|
||||
<p>Plastics offer significant material benefits, such as durability and versatility, yet their
|
||||
widespread use has led to severe environmental pollution and waste management
|
||||
challenges. This thesis develops alternative concepts for collaborative participation in
|
||||
recycling processes by examining existing waste management systems. Exploring the
|
||||
historical and material context of plastics, it investigates the role of making and hacking as
|
||||
transformative practices in waste revaluation. Drawing on theories from Discard Studies,
|
||||
Material Ecocriticism, and Valuation Studies, it applies methods to examine human-waste
|
||||
relationships and the shifting perception of objects between value and non-value. Practical
|
||||
investigations, including workshop-based experiments with polymer identification and
|
||||
machine-based interventions, provide hands-on insights into the material properties of
|
||||
discarded plastics. These experiments reveal their epistemic potential, leading to the
|
||||
introduction of novel archiving practices and knowledge structures that form an integrated
|
||||
methodology for artistic research and practice. Inspired by the Materialstudien of the
|
||||
Bauhaus Vorkurs, the workshop not only explores material engagement but also offers new
|
||||
insights for educational science, advocating for peer-learning scenarios. Through these
|
||||
approaches, this research fosters a socially transformative relationship with waste,
|
||||
emphasizing participation, design, and speculative material reuse. Findings are evaluated
|
||||
through participant feedback and workshop outcomes, contributing to a broader discussion
|
||||
on waste as both a challenge and an opportunity for sustainable futures and a material
|
||||
reality of the human experience.</p>

|
||||
<p>Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system. On top of the meanest cyberpunk vibes my past self was able to conjure.</p>
|
||||
<p>Enjoy!</p>

|
||||
<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
|
||||
Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
|
||||
<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
|
||||
It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
|
||||
<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
|
||||
For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
|
||||
<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>

|

<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

<p><img src="/assets/images/electricity_tiers.png" alt="The electricity tiers defined by the UN" /></p>
|
||||
<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
|
||||
The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
|
||||
But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

<p>Towards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur.
|
||||
The goal was to work on one of the 17 UN-defined sustainable development goals – electricity.</p>
|
||||
<p>Worldwide, an estimated 1 billion people have no or insubstantial access to the grid.
|
||||
Some of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.</p>

<p>This is Tashi Gang, a village close to the Monastery. It houses around 50 people and only has road access during 3-4 months in the summer. For the rest of the time, the people rely on first aid services by helicopter, which can only be called with a working cell phone tower.</p>

|
||||
<h2 id="The_Project">The Project</h2>
|
||||
<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
|
||||
<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
|
||||
<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
|
||||
The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
|
||||
To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
|
||||
I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
|
||||
The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>
|
||||
<h2 id="Research">Research</h2>
|
||||
<p><img src="/assets/images/Key_Monastery_Spiti.png" alt="The Electricity layout of the Key Monastery" /></p>
|
||||
<h2 id="Data_Collection">Data Collection</h2>
|
||||
<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
|
||||
<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
|
||||
<p>The participants range from 11 to 53 years, with an average of 17 years.
|
||||
The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
|
||||
The average total amount of electrical devices is around 11 electrical appliances per house.</p>
|
||||
<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
|
||||
<blockquote>
|
||||
<p>Average quality in summer: 7.1
|
||||
Average quality in monsoon: 5.6
|
||||
Average quality in autumn: 7.1
|
||||
Average quality in winter: 4.0</p>
|
||||
</blockquote>
|
||||
<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
|
||||
As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
|
||||
As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
|
||||
<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
|
||||
<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
|
||||
<h2 id="Simulation">Simulation</h2>
|
||||
<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
|
||||
<img src="/assets/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
|
||||
<img src="/assets/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
|
||||
<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
|
||||
And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
|
||||
<h2 id="Closing_words">Closing words</h2>
|
||||
<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
|
||||
But ensuring efficient use is not the only way to bring down the overall demand.</p>
|
||||
<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
|
||||
By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
|
||||
<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
|
||||
<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
|
||||
I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>

<content type="html" xml:base="https://aron.petau.net/blog/plastic-recycling/"><p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
|
||||
Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
|
||||
The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
|
||||
<p>What can be done about it?
|
||||
We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
|
||||
Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
|
||||
<p>{% include video id="vqWwUx8l_Io" provider="youtube" %}</p>
|
||||
<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
|
||||
<h1 id="The_Master_Plan">The Master Plan</h1>
|
||||
<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
|
||||
This only really works when I am thinking in a local and decentral environment.
|

The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
|
||||
Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
|
||||
Now I have to take apart the trash into evenly sized particles.

<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
|
||||
<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
|
||||
<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
|
||||
We cut it in half and attached it to the shredder box.</p>
|
||||
<p>{% include video id="QwVp1zmAA4Q" provider="youtube" %}</p>
|
||||
<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
|
||||
<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
|
||||
As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
|
||||
<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
|
||||
<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
|
||||
<p>Here you can see the extrusion process in action.</p>
|
||||
<p>{% include video id="FX6--pYrPVs" provider="youtube" %}</p>
|
||||
<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
|
||||
<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
|
||||
<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" />
|
||||
So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
|
||||
<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
|
||||
The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

|
||||
<p>Last year, I wrote my thesis during the pandemic. With the struggles our university had transitioning to online teaching, I selected a guided topic, although my initial dream was to start writing about my proposed plan for automated plastic recycling. You can read more about that here:</p>
|
||||

|
||||
<p>I chose a project that wanted to examine the possibilities of a novel smart hearing protection device specifically designed for auditory hypersensitivity, which is often, but not always, and not exclusively a phenomenon visible in people with an autism spectrum disorder.</p>
|
||||
<p>A common reaction to this elevated sensitivity is stress and avoidance behavior, often leading to very awkward social situations and impairing the ability to take part in social situations.</p>
|
||||
<p>Schools are one such social situation and we all know the stress a noisy classroom can produce. Concentration is gone, and education, as well as essential skills like language reproduction, suffer.</p>
|
||||
<p>There is lots of prior research on these fields, and there is some evidence that sensory information in people on the Autism spectrum is processed differently than in a neurotypical brain. It seems that a certain adaptability, needed to overcome noise issues and bridge asynchrony between auditory and visual sensory input, is reduced in some people on the Autism Spectrum.</p>
|
||||
<p>In essence, my experiment was responsible for looking at neurotypical people and measuring any effect on language perception produced by varying the delay between auditory and visual input, as well as the loudness.</p>
|
||||
<p>Here, I had the possibility to conduct an entire reaction-time-based experiment with over 70 participants and went through all the struggles that come with proper science.
|
||||
I did extensive literature research, coded the experiment, and learned a lot about the reasons nobody really ever does reaction time-based studies like this via a common internet browser.
|
||||
It was an almost 9 months long learning experience full of doing things I had never done before.</p>
|
||||
<p>I learned and got to love writing in Latex, had to learn JavaScript for the efficient serving of the stimuli, and R for the statistical analysis. I also got to brush up on my data visualization skills in Python and made some pretty graphs of the results.</p>
|
||||
<p>The experiment is still working and online if you want to have a look at it. Be mindful though that measuring reaction speed every millisecond is important, which is why it makes heavy use of your browser cache and has been known to crash and defeat some not-so-tough computers.</p>

|

</div>
|
||||
<p>Even with writing alone I had extensive helpful feedback from my supervisors and learned a lot about scientific processes and associated considerations.</p>
|
||||
<p>There was always the next unsolvable problem. Just one example was scientificity and ethical considerations clashing, data privacy against the accuracy of results. Since the machines participants participated on, were private devices, I was unable to know important data like their internet speed and provider, their type of GPU, and their type of external hardware. Turns out, for an auditory experiment, the type and setup of the speakers do play an important role and influence response speed.</p>
|
||||
<p>The final version of my thesis has something around 80 pages, much of it utterly boring, but nevertheless important statistical analyses.

||||

<p>I am a fan and proponent of open source and open science practices.
|
||||
So here you can also find the rest of the project with the original source code.
|
||||
I am not yet where I want to be with my documentation practices, and it scares me a bit that anyone can now have a full grasp of all the mistakes I did, but I am throwing this out there as a practice step. I learned and gained a lot from looking at other people's projects and I strive to be open about my processes too.</p>

|
||||
<p>I have attended a fair share of philosophical seminars in my studies and consider it a core topic connected both to science and to digital environments.
|
||||
Normative and feminist social theory, as well as the theory of science and phenomenology, are all brought to me through seminar formats at university and made up a good part of my education there.
|
||||
I find it hard to properly demonstrate what interests me without presenting often long-winded and dull term papers.
|
||||
The courses I loved most also often had a format with a weekly hand-in, where students are asked to comment on the paper they just read to identify points to carry into next week's discussion. I am incredibly thankful for this methodology of approaching complex philosophical works, often complete books with supplicant essays surrounding the course topic. In my opinion, nearly all of the value created during these seminars is contained within the live discussions fed by reading materials and little opinion pieces in the form of forum comments. That's why I decided to share here a selection of these weekly commentaries and the sources they are based upon. They are often unrefined and informal, but they indicate the centerpiece of the seminars and demonstrate many thought processes that happened within me during these sessions. Although I took only a small selection, in sum they are a substantial read. Feel free to just skip through and read what catches your interest.</p>

<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
|
||||
<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.

<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them. I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.

|
||||
<p>Plastics offer significant material benefits, such as durability and versatility, yet their
|
||||
widespread use has led to severe environmental pollution and waste management
|
||||
challenges. This thesis develops alternative concepts for collaborative participation in
|
||||
recycling processes by examining existing waste management systems. Exploring the
|
||||
historical and material context of plastics, it investigates the role of making and hacking as
|
||||
transformative practices in waste revaluation. Drawing on theories from Discard Studies,
|
||||
Material Ecocriticism, and Valuation Studies, it applies methods to examine human-waste
|
||||
relationships and the shifting perception of objects between value and non-value. Practical
|
||||
investigations, including workshop-based experiments with polymer identification and
|
||||
machine-based interventions, provide hands-on insights into the material properties of
|
||||
discarded plastics. These experiments reveal their epistemic potential, leading to the
|
||||
introduction of novel archiving practices and knowledge structures that form an integrated
|
||||
methodology for artistic research and practice. Inspired by the Materialstudien of the
|
||||
Bauhaus Vorkurs, the workshop not only explores material engagement but also offers new
|
||||
insights for educational science, advocating for peer-learning scenarios. Through these
|
||||
approaches, this research fosters a socially transformative relationship with waste,
|
||||
emphasizing participation, design, and speculative material reuse. Findings are evaluated
|
||||
through participant feedback and workshop outcomes, contributing to a broader discussion
|
||||
on waste as both a challenge and an opportunity for sustainable futures and a material
|
||||
reality of the human experience.</p>

|
||||
<p>Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system. On top of the meanest cyberpunk vibes my past self was able to conjure.</p>

<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
|
||||
Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
|
||||
<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
|
||||
It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
|
||||
<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
|
||||
For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
|
||||
<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>

|

<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

<p><img src="/assets/images/electricity_tiers.png" alt="The electricity tiers defined by the UN" /></p>
|
||||
<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
|
||||
The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
|
||||
But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

The goal was to work on one of the 17 UN-defined sustainable development goals – electricity.</p>
|
||||
<p>Worldwide, an estimated 1 billion people have no or insubstantial access to the grid.
|

Some of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.</p>

<h2 id="The_Project">The Project</h2>
|
||||
<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
|
||||
<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
|
||||
<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
|
||||
The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
|
||||
To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
|
||||
I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.

The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

||||
<h2 id="Research">Research</h2>

<p><img src="/assets/images/Key_Monastery_Spiti.png" alt="The Electricity layout of the Key Monastery" /></p>
|
||||
<h2 id="Data_Collection">Data Collection</h2>
|
||||
<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
|
||||
<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
|
||||
<p>The participants range from 11 to 53 years, with an average of 17 years.
|
||||
The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
|
||||
The average total amount of electrical devices is around 11 electrical appliances per house.</p>
|
||||
<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
|
||||
<blockquote>
|
||||
<p>Average quality in summer: 7.1
|
||||
Average quality in monsoon: 5.6
|
||||
Average quality in autumn: 7.1
|
||||
Average quality in winter: 4.0</p>
|
||||
</blockquote>
|
||||
<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
|
||||
As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
|
||||
As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
|
||||
<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
|
||||
<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
|
||||
<h2 id="Simulation">Simulation</h2>
|
||||
<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
|
||||
<img src="/assets/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
|
||||
<img src="/assets/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
|
||||
<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
|
||||
And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
|
||||
<h2 id="Closing_words">Closing words</h2>
|
||||
<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
|
||||
But ensuring efficient use is not the only way to bring down the overall demand.</p>
|
||||
<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
|
||||
By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
|
||||
<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
|
||||
<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
|
||||
I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>

<title>Plastic Recycling</title>
|

|
||||
<description xml:base="https://aron.petau.net/blog/plastic-recycling/"><p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
|
||||
Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
|
||||
The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
|
||||
<p>What can be done about it?
|
||||
We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
|
||||
Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
|
||||
<p>{% include video id="vqWwUx8l_Io" provider="youtube" %}</p>
|
||||
<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
|
||||
<h1 id="The_Master_Plan">The Master Plan</h1>
|
||||
<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
|
||||
This only really works when I am thinking in a local and decentral environment.
|
||||
The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
|
||||
Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
|
||||
Now I have to take apart the trash into evenly sized particles.
|
||||

<h2 id="The_Shredder">The Shredder</h2>
|
||||
<p>We built the Precious Plastic Shredder!</p>

|
||||
<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
|
||||
<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
|
||||
<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
|
||||
We cut it in half and attached it to the shredder box.</p>
|
||||
<p>{% include video id="QwVp1zmAA4Q" provider="youtube" %}</p>
|
||||
<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
|
||||
<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
|
||||
As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
|
||||
<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
|
||||
<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
|
||||
<p>Here you can see the extrusion process in action.</p>
|
||||
<p>{% include video id="FX6--pYrPVs" provider="youtube" %}</p>
|
||||
<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
|
||||
<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
|
||||
<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" />
|
||||
So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
|
||||
<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
|
||||
The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

|
||||
<p>Last year, I wrote my thesis during the pandemic. With the struggles our university had transitioning to online teaching, I selected a guided topic, although my initial dream was to start writing about my proposed plan for automated plastic recycling. You can read more about that here:</p>

||||

|
||||
<p>I chose a project that wanted to examine the possibilities of a novel smart hearing protection device specifically designed for auditory hypersensitivity, which is often, but not always, and not exclusively a phenomenon visible in people with an autism spectrum disorder.</p>
|
||||
<p>A common reaction to this elevated sensitivity is stress and avoidance behavior, often leading to very awkward social situations and impairing the ability to take part in social situations.</p>
|
||||
<p>Schools are one such social situation and we all know the stress a noisy classroom can produce. Concentration is gone, and education, as well as essential skills like language reproduction, suffer.</p>
|
||||
<p>There is lots of prior research on these fields, and there is some evidence that sensory information in people on the Autism spectrum is processed differently than in a neurotypical brain. It seems that a certain adaptability, needed to overcome noise issues and bridge asynchrony between auditory and visual sensory input, is reduced in some people on the Autism Spectrum.</p>
|
||||
<p>In essence, my experiment was responsible for looking at neurotypical people and measuring any effect on language perception produced by varying the delay between auditory and visual input, as well as the loudness.</p>
|
||||
<p>Here, I had the possibility to conduct an entire reaction-time-based experiment with over 70 participants and went through all the struggles that come with proper science.
|
||||
I did extensive literature research, coded the experiment, and learned a lot about the reasons nobody really ever does reaction time-based studies like this via a common internet browser.
|
||||
It was an almost 9 months long learning experience full of doing things I had never done before.</p>
|
||||
<p>I learned and got to love writing in Latex, had to learn JavaScript for the efficient serving of the stimuli, and R for the statistical analysis. I also got to brush up on my data visualization skills in Python and made some pretty graphs of the results.</p>
|
||||
<p>The experiment is still working and online if you want to have a look at it. Be mindful though that measuring reaction speed every millisecond is important, which is why it makes heavy use of your browser cache and has been known to crash and defeat some not-so-tough computers.</p>

|
||||
</div>
|
||||
<p>Even with writing alone I had extensive helpful feedback from my supervisors and learned a lot about scientific processes and associated considerations.</p>
|
||||
<p>There was always the next unsolvable problem. Just one example was scientificity and ethical considerations clashing, data privacy against the accuracy of results. Since the machines participants participated on, were private devices, I was unable to know important data like their internet speed and provider, their type of GPU, and their type of external hardware. Turns out, for an auditory experiment, the type and setup of the speakers do play an important role and influence response speed.</p>
|
||||
<p>The final version of my thesis has something around 80 pages, much of it utterly boring, but nevertheless important statistical analyses.

So here you can also find the rest of the project with the original source code.
|
||||
I am not yet where I want to be with my documentation practices, and it scares me a bit that anyone can now have a full grasp of all the mistakes I did, but I am throwing this out there as a practice step. I learned and gained a lot from looking at other people's projects and I strive to be open about my processes too.</p>

|
||||
<p>I have attended a fair share of philosophical seminars in my studies and consider it a core topic connected both to science and to digital environments.
|
||||
Normative and feminist social theory, as well as the theory of science and phenomenology, are all brought to me through seminar formats at university and made up a good part of my education there.
|
||||
I find it hard to properly demonstrate what interests me without presenting often long-winded and dull term papers.
|
||||
The courses I loved most also often had a format with a weekly hand-in, where students are asked to comment on the paper they just read to identify points to carry into next week's discussion. I am incredibly thankful for this methodology of approaching complex philosophical works, often complete books with supplicant essays surrounding the course topic. In my opinion, nearly all of the value created during these seminars is contained within the live discussions fed by reading materials and little opinion pieces in the form of forum comments. That's why I decided to share here a selection of these weekly commentaries and the sources they are based upon. They are often unrefined and informal, but they indicate the centerpiece of the seminars and demonstrate many thought processes that happened within me during these sessions. Although I took only a small selection, in sum they are a substantial read. Feel free to just skip through and read what catches your interest.</p>

<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
|
||||
<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.
|
||||
In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.

<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them. I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.

||||
Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.

<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
|
||||
<p>I want more than designing figurines or wearables.
|

I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.

<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
|
||||
And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
|
||||
<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

|
||||
<p>Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system. On top of the meanest cyberpunk vibes my past self was able to conjure.</p>

<p>Enjoy!</p>

<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
|
||||
Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
|
||||
<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
|
||||
It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
|
||||
<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
|
||||
For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
|
||||
<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>

|
||||
<p>Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system. On top of the meanest cyberpunk vibes my past self was able to conjure.</p>
|
||||
<p>Enjoy!</p>

<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
|
||||
Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
|
||||
<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
|
||||
It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
|
||||
<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
|
||||
For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
|
||||
<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>

<content type="html" xml:base="https://aron.petau.net/blog/plastic-recycling/"><p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
|
||||
Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
|
||||
The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
|
||||
<p>What can be done about it?
|
||||
We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
|
||||
Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
|
||||
<p>{% include video id="vqWwUx8l_Io" provider="youtube" %}</p>
|
||||
<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
|
||||
<h1 id="The_Master_Plan">The Master Plan</h1>
|
||||
<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
|
||||
This only really works when I am thinking in a local and decentral environment.
|
||||
The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
|
||||
Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
|
||||
Now I have to take apart the trash into evenly sized particles.

<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
|
||||
<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
|
||||
<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
|
||||
We cut it in half and attached it to the shredder box.</p>
|
||||
<p>{% include video id="QwVp1zmAA4Q" provider="youtube" %}</p>
|
||||
<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
|
||||
<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
|
||||
As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
|
||||
<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
|
||||
<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
|
||||
<p>Here you can see the extrusion process in action.</p>
|
||||
<p>{% include video id="FX6--pYrPVs" provider="youtube" %}</p>
|
||||
<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
|
||||
<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
|
||||
<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" />
|
||||
So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
|
||||
<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
|
||||
The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
|
||||
<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.

In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.

<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them. I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
|

Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.

<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
|
||||
<p>I want more than designing figurines or wearables.

<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
|
||||
<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.
|
||||
In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.

<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them. I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
|
||||
Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.

<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
|
||||
<p>I want more than designing figurines or wearables.
|
||||
I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.

<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
|
||||
And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
|
||||
<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
|
||||
Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
|
||||
<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
|
||||
It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
|
||||
<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
|
||||
For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
|
||||
<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>

|
||||
<p>I have attended a fair share of philosophical seminars in my studies and consider it a core topic connected both to science and to digital environments.
|
||||
Normative and feminist social theory, as well as the theory of science and phenomenology, are all brought to me through seminar formats at university and made up a good part of my education there.
|
||||
I find it hard to properly demonstrate what interests me without presenting often long-winded and dull term papers.
|
||||
The courses I loved most also often had a format with a weekly hand-in, where students are asked to comment on the paper they just read to identify points to carry into next week's discussion. I am incredibly thankful for this methodology of approaching complex philosophical works, often complete books with supplicant essays surrounding the course topic. In my opinion, nearly all of the value created during these seminars is contained within the live discussions fed by reading materials and little opinion pieces in the form of forum comments. That's why I decided to share here a selection of these weekly commentaries and the sources they are based upon. They are often unrefined and informal, but they indicate the centerpiece of the seminars and demonstrate many thought processes that happened within me during these sessions. Although I took only a small selection, in sum they are a substantial read. Feel free to just skip through and read what catches your interest.</p>

<description xml:base="https://aron.petau.net/blog/philosophy copy/"><h2 id="Critical_considerations_during_my_studies">Critical considerations during my studies</h2>
|
||||
<p>I have attended a fair share of philosophical seminars in my studies and consider it a core topic connected both to science and to digital environments.
|
||||
Normative and feminist social theory, as well as the theory of science and phenomenology, are all brought to me through seminar formats at university and made up a good part of my education there.
|
||||
I find it hard to properly demonstrate what interests me without presenting often long-winded and dull term papers.
|
||||
The courses I loved most also often had a format with a weekly hand-in, where students are asked to comment on the paper they just read to identify points to carry into next week's discussion. I am incredibly thankful for this methodology of approaching complex philosophical works, often complete books with supplicant essays surrounding the course topic. In my opinion, nearly all of the value created during these seminars is contained within the live discussions fed by reading materials and little opinion pieces in the form of forum comments. That's why I decided to share here a selection of these weekly commentaries and the sources they are based upon. They are often unrefined and informal, but they indicate the centerpiece of the seminars and demonstrate many thought processes that happened within me during these sessions. Although I took only a small selection, in sum they are a substantial read. Feel free to just skip through and read what catches your interest.</p>

<p>Plastics offer significant material benefits, such as durability and versatility, yet their
|
||||
widespread use has led to severe environmental pollution and waste management
|
||||
challenges. This thesis develops alternative concepts for collaborative participation in
|
||||
recycling processes by examining existing waste management systems. Exploring the
|
||||
historical and material context of plastics, it investigates the role of making and hacking as
|
||||
transformative practices in waste revaluation. Drawing on theories from Discard Studies,
|
||||
Material Ecocriticism, and Valuation Studies, it applies methods to examine human-waste
|
||||
relationships and the shifting perception of objects between value and non-value. Practical
|
||||
investigations, including workshop-based experiments with polymer identification and
|
||||
machine-based interventions, provide hands-on insights into the material properties of
|
||||
discarded plastics. These experiments reveal their epistemic potential, leading to the
|
||||
introduction of novel archiving practices and knowledge structures that form an integrated
|
||||
methodology for artistic research and practice. Inspired by the Materialstudien of the
|
||||
Bauhaus Vorkurs, the workshop not only explores material engagement but also offers new
|
||||
insights for educational science, advocating for peer-learning scenarios. Through these
|
||||
approaches, this research fosters a socially transformative relationship with waste,
|
||||
emphasizing participation, design, and speculative material reuse. Findings are evaluated
|
||||
through participant feedback and workshop outcomes, contributing to a broader discussion
|
||||
on waste as both a challenge and an opportunity for sustainable futures and a material
|
||||
reality of the human experience.</p>

<content type="html" xml:base="https://aron.petau.net/blog/plastic-recycling/"><p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
|
||||
Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
|
||||
The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
|
||||
<p>What can be done about it?
|
||||
We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
|
||||
Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
|
||||
<p>{% include video id="vqWwUx8l_Io" provider="youtube" %}</p>
|
||||
<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
|
||||
<h1 id="The_Master_Plan">The Master Plan</h1>
|
||||
<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
|
||||
This only really works when I am thinking in a local and decentral environment.
|
||||
The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
|
||||
Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
|
||||
Now I have to take apart the trash into evenly sized particles.

||||

|
||||
<p>We built the Precious Plastic Shredder!</p>

|
||||
<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
|
||||
<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
|
||||
<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
|
||||
We cut it in half and attached it to the shredder box.</p>
|
||||
<p>{% include video id="QwVp1zmAA4Q" provider="youtube" %}</p>
|
||||
<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
|
||||
<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
|
||||
As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
|
||||
<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
|
||||
<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
|
||||
<p>Here you can see the extrusion process in action.</p>
|
||||
<p>{% include video id="FX6--pYrPVs" provider="youtube" %}</p>
|
||||
<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
|
||||
<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
|
||||
<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" />
|
||||
So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
|
||||
<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
|
||||
The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

|
||||
<p>Last year, I wrote my thesis during the pandemic. With the struggles our university had transitioning to online teaching, I selected a guided topic, although my initial dream was to start writing about my proposed plan for automated plastic recycling. You can read more about that here:</p>

|
||||
<p>I chose a project that wanted to examine the possibilities of a novel smart hearing protection device specifically designed for auditory hypersensitivity, which is often, but not always, and not exclusively a phenomenon visible in people with an autism spectrum disorder.</p>
|
||||
<p>A common reaction to this elevated sensitivity is stress and avoidance behavior, often leading to very awkward social situations and impairing the ability to take part in social situations.</p>
|
||||
<p>Schools are one such social situation and we all know the stress a noisy classroom can produce. Concentration is gone, and education, as well as essential skills like language reproduction, suffer.</p>
|
||||
<p>There is lots of prior research on these fields, and there is some evidence that sensory information in people on the Autism spectrum is processed differently than in a neurotypical brain. It seems that a certain adaptability, needed to overcome noise issues and bridge asynchrony between auditory and visual sensory input, is reduced in some people on the Autism Spectrum.</p>
|
||||
<p>In essence, my experiment was responsible for looking at neurotypical people and measuring any effect on language perception produced by varying the delay between auditory and visual input, as well as the loudness.</p>
|
||||
<p>Here, I had the possibility to conduct an entire reaction-time-based experiment with over 70 participants and went through all the struggles that come with proper science.
|
||||
I did extensive literature research, coded the experiment, and learned a lot about the reasons nobody really ever does reaction time-based studies like this via a common internet browser.
|
||||
It was an almost 9 months long learning experience full of doing things I had never done before.</p>
|
||||
<p>I learned and got to love writing in Latex, had to learn JavaScript for the efficient serving of the stimuli, and R for the statistical analysis. I also got to brush up on my data visualization skills in Python and made some pretty graphs of the results.</p>
|
||||
<p>The experiment is still working and online if you want to have a look at it. Be mindful though that measuring reaction speed every millisecond is important, which is why it makes heavy use of your browser cache and has been known to crash and defeat some not-so-tough computers.</p>

|
||||
</div>
|
||||
<p>Even with writing alone I had extensive helpful feedback from my supervisors and learned a lot about scientific processes and associated considerations.</p>
|
||||
<p>There was always the next unsolvable problem. Just one example was scientificity and ethical considerations clashing, data privacy against the accuracy of results. Since the machines participants participated on, were private devices, I was unable to know important data like their internet speed and provider, their type of GPU, and their type of external hardware. Turns out, for an auditory experiment, the type and setup of the speakers do play an important role and influence response speed.</p>
|
||||
<p>The final version of my thesis has something around 80 pages, much of it utterly boring, but nevertheless important statistical analyses.

|

<p>I am a fan and proponent of open source and open science practices.
|
||||
So here you can also find the rest of the project with the original source code.
|
||||
I am not yet where I want to be with my documentation practices, and it scares me a bit that anyone can now have a full grasp of all the mistakes I did, but I am throwing this out there as a practice step. I learned and gained a lot from looking at other people's projects and I strive to be open about my processes too.</p>

I am not yet where I want to be with my documentation practices, and it scares me a bit that anyone can now have a full grasp of all the mistakes I did, but I am throwing this out there as a practice step. I learned and gained a lot from looking at other people's projects and I strive to be open about my processes too.</p>

<p>The original video stimuli are not mine and I have no right releasing them, so they are omitted here.</p>

<content type="html" xml:base="https://aron.petau.net/blog/plastic-recycling/"><p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
|
||||
Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
|
||||
The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
|
||||
<p>What can be done about it?
|
||||
We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
|
||||
Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
|
||||
<p>{% include video id="vqWwUx8l_Io" provider="youtube" %}</p>
|
||||
<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
|
||||
<h1 id="The_Master_Plan">The Master Plan</h1>
|
||||
<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
|
||||
This only really works when I am thinking in a local and decentral environment.
|
||||
The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
|
||||
Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
|
||||
Now I have to take apart the trash into evenly sized particles.

<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
|
||||
<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
|
||||
<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
|
||||
We cut it in half and attached it to the shredder box.</p>
|
||||
<p>{% include video id="QwVp1zmAA4Q" provider="youtube" %}</p>
|
||||
<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
|
||||
<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
|
||||
As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
|
||||
<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
|
||||
<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
|
||||
<p>Here you can see the extrusion process in action.</p>
|
||||
<p>{% include video id="FX6--pYrPVs" provider="youtube" %}</p>
|
||||
<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
|
||||
<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
|
||||
<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" />
|
||||
So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
|
||||
<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
|
||||
The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

|
||||
<p>Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system. On top of the meanest cyberpunk vibes my past self was able to conjure.</p>
|
||||
<p>Enjoy!</p>

|
||||
<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
|
||||
Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
|
||||
<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
|
||||
It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
|
||||
<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
|
||||
For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
|
||||
<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>

<p>Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system. On top of the meanest cyberpunk vibes my past self was able to conjure.</p>
|
||||
<p>Enjoy!</p>

<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
|
||||
Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
|
||||
<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
|
||||
It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
|
||||
<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
|
||||
For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
|
||||
<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>

<content type="html" xml:base="https://aron.petau.net/blog/plastic-recycling/"><p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
|
||||
Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
|
||||
The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
|
||||
<p>What can be done about it?
|
||||
We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
|
||||
Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
|
||||
<p>{% include video id="vqWwUx8l_Io" provider="youtube" %}</p>
|
||||
<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
|
||||
<h1 id="The_Master_Plan">The Master Plan</h1>
|
||||
<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
|
||||
This only really works when I am thinking in a local and decentral environment.
|
||||
The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
|
||||
Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
|
||||
Now I have to take apart the trash into evenly sized particles.

|
||||
<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
|
||||
<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
|
||||
<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
|
||||
We cut it in half and attached it to the shredder box.</p>
|
||||
<p>{% include video id="QwVp1zmAA4Q" provider="youtube" %}</p>
|
||||
<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
|
||||
<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
|
||||
As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
|
||||
<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
|
||||
<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
|
||||
<p>Here you can see the extrusion process in action.</p>
|
||||
<p>{% include video id="FX6--pYrPVs" provider="youtube" %}</p>
|
||||
<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
|
||||
<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
|
||||
<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" />
|
||||
So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
|
||||
<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
|
||||
The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

|
||||
<p>Plastics offer significant material benefits, such as durability and versatility, yet their
|
||||
widespread use has led to severe environmental pollution and waste management
|
||||
challenges. This thesis develops alternative concepts for collaborative participation in
|
||||
recycling processes by examining existing waste management systems. Exploring the
|
||||
historical and material context of plastics, it investigates the role of making and hacking as
|
||||
transformative practices in waste revaluation. Drawing on theories from Discard Studies,
|
||||
Material Ecocriticism, and Valuation Studies, it applies methods to examine human-waste
|
||||
relationships and the shifting perception of objects between value and non-value. Practical
|
||||
investigations, including workshop-based experiments with polymer identification and
|
||||
machine-based interventions, provide hands-on insights into the material properties of
|
||||
discarded plastics. These experiments reveal their epistemic potential, leading to the
|
||||
introduction of novel archiving practices and knowledge structures that form an integrated
|
||||
methodology for artistic research and practice. Inspired by the Materialstudien of the
|
||||
Bauhaus Vorkurs, the workshop not only explores material engagement but also offers new
|
||||
insights for educational science, advocating for peer-learning scenarios. Through these
|
||||
approaches, this research fosters a socially transformative relationship with waste,
|
||||
emphasizing participation, design, and speculative material reuse. Findings are evaluated
|
||||
through participant feedback and workshop outcomes, contributing to a broader discussion
|
||||
on waste as both a challenge and an opportunity for sustainable futures and a material
|
||||
reality of the human experience.</p>

|
||||
<p>Plastics offer significant material benefits, such as durability and versatility, yet their
|
||||
widespread use has led to severe environmental pollution and waste management
|
||||
challenges. This thesis develops alternative concepts for collaborative participation in
|
||||
recycling processes by examining existing waste management systems. Exploring the
|
||||
historical and material context of plastics, it investigates the role of making and hacking as
|
||||
transformative practices in waste revaluation. Drawing on theories from Discard Studies,
|
||||
Material Ecocriticism, and Valuation Studies, it applies methods to examine human-waste
|
||||
relationships and the shifting perception of objects between value and non-value. Practical
|
||||
investigations, including workshop-based experiments with polymer identification and
|
||||
machine-based interventions, provide hands-on insights into the material properties of
|
||||
discarded plastics. These experiments reveal their epistemic potential, leading to the
|
||||
introduction of novel archiving practices and knowledge structures that form an integrated
|
||||
methodology for artistic research and practice. Inspired by the Materialstudien of the
|
||||
Bauhaus Vorkurs, the workshop not only explores material engagement but also offers new
|
||||
insights for educational science, advocating for peer-learning scenarios. Through these
|
||||
approaches, this research fosters a socially transformative relationship with waste,
|
||||
emphasizing participation, design, and speculative material reuse. Findings are evaluated
|
||||
through participant feedback and workshop outcomes, contributing to a broader discussion
|
||||
on waste as both a challenge and an opportunity for sustainable futures and a material
|
||||
reality of the human experience.</p>

<p>Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system.

<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
|
||||
Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
|
||||
<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
|
||||
It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
|
||||
<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
|
||||
For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
|
||||
<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>

<content type="html" xml:base="https://aron.petau.net/blog/plastic-recycling/"><p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
|
||||
Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
|
||||
The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
|
||||
<p>What can be done about it?
|
||||
We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.

This only really works when I am thinking in a local and decentral environment.

The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.

Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.

<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
|

<p>Here you can see the extrusion process in action.</p>
|

<p>{% include video id="FX6--pYrPVs" provider="youtube" %}</p>
|
||||
<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
|
||||
<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
|
||||
<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" />
|
||||
So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
|
||||
<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
|
||||
The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

<description xml:base="https://aron.petau.net/blog/plastic-recycling/"><p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
|
||||
Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
|
||||
The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
|
||||
<p>What can be done about it?
|
||||
We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
|
||||
Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>

<p>Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system.

<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
|
||||
Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
|
||||
<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
|
||||
It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
|
||||
<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
|
||||
For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
|
||||
<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>

<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

|
||||
<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
|
||||
The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
|
||||
But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>
|

<h3 id="Location">Location</h3>
|
||||
<p>Towards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur.
|
||||
The goal was to work on one of the 17 UN-defined sustainable development goals – electricity.</p>
|
||||
<p>Worldwide, an estimated 1 billion people have no or insubstantial access to the grid.
|
||||
Some of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.</p>

<p><img src="/assets/images/tashi_gang.jpg" alt="tashi gang" /></p>
|

<p>This is Tashi Gang, a village close to the Monastery. It houses around 50 people and only has road access during 3-4 months in the summer. For the rest of the time, the people rely on first aid services by helicopter, which can only be called with a working cell phone tower.</p>

|

<h2 id="The_Project">The Project</h2>
|
||||
<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
|
||||
<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
|
||||
<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
|
||||
The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
|
||||
To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
|
||||
I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
|
||||
The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>
|
||||
<h2 id="Research">Research</h2>
|
||||
<p><img src="/assets/images/Key_Monastery_Spiti.png" alt="The Electricity layout of the Key Monastery" /></p>
|
||||
<h2 id="Data_Collection">Data Collection</h2>
|
||||
<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
|
||||
<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
|
||||
<p>The participants range from 11 to 53 years, with an average of 17 years.
|
||||
The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
|
||||
The average total amount of electrical devices is around 11 electrical appliances per house.</p>
|
||||
<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
|
||||
<blockquote>
|
||||
<p>Average quality in summer: 7.1
|
||||
Average quality in monsoon: 5.6
|
||||
Average quality in autumn: 7.1
|
||||
Average quality in winter: 4.0</p>
|
||||
</blockquote>
|
||||
<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
|
||||
As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
|
||||
As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
|
||||
<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
|
||||
<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
|
||||
<h2 id="Simulation">Simulation</h2>
|
||||
<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
|
||||
<img src="/assets/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
|
||||
<img src="/assets/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
|
||||
<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
|
||||
And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
|
||||
<h2 id="Closing_words">Closing words</h2>
|
||||
<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
|
||||
But ensuring efficient use is not the only way to bring down the overall demand.</p>
|
||||
<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
|
||||
By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
|
||||
<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
|
||||
<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
|
||||
I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
