Sugarcrete: Annopen access, eco-friendly and remarkably effective building material

slrpnk.net/post/21314742

slrpnk.netSugarcrete: Annopen access, eco-friendly and remarkably effective building material - SLRPNKAt Panchsheel Inter College in Uttar Pradesh, students now study inside a new school wing built not from concrete or traditional brick, but from sugarcane. The innovation was born at the University of East London (UEL) and its creators argue it could reshape how buildings are made and how the planet pays for it. Sugarcrete combines the fibrous residues of sugarcane, called bagasse, with sand and mineral binders to produce lightweight, interlocking blocks. Lab tests show that Sugarcrete has strong fire resistance, acoustic dampening, and thermal insulation properties. It’s been tested to industrial standards and passed with flying colors. In terms of climate impact, the material is a standout. It’s six times less carbon-intensive than standard bricks, and twenty times less than concrete, by some estimates. Yet the real excitement doesn’t only come from what Sugarcrete is, but how it’s made and used. It is purposely ‘open access’ in order to establish partnerships to produce new bio-waste-based construction materials where sugarcane is grown. Unlike conventional building materials locked behind patents, Sugarcrete can be made by anyone with the right ingredients and basic manufacturing tools. That choice decentralizes construction innovation, allowing small-scale producers — especially in the Global South — to lead.

The Kratky Hydroponic Lettuce Wall will be comprised of a couple of things:

1) A utility shelf with adjustable shelving
2) Full spectrum LED "grow" light strips w/ timer
3) Grow bins

That's it.

The utility shelf can be broken down into the following requirements:
- DANGER!!! WARNING!!! IMPORTANT!!!: The shelves should be able to actually hold the weight of your grow bins. Water is heavy. Many shelves by themselves cannot support the weight of the water and will need support. So check the weight rating on the shelves you get. We'll continue to talk about this further as we built out the shelf.
- ANOTHER DANGER!!! WARNING!!! IMPORTANT!!!: You need a way to anchor your shelves to the wall SECURELY!!! You don't want this thing tipping over. You build it too high and it falls on your kid or dog or cat and they may die. Secure this to your wall. Especially the higher you build it.
- Shelves need to be adjustable to allow enough space for the bin to sit and for the plant to grow
- A way to attach the light strips to the shelf above the grow bin
- Bonus: Make it pretty

The Grow Light Strips can be broken into the following requirements:
- They should fit the length of the shelf you pick and be attachable to it in some way
- You should be able to control them with a timer (either on the light itself or set up with a wall socket timer
- Have a method of increasing the light or decreasing the light (easily add more light strips if needed, or adjust brightness, etc)
- Be full spectrum "grow" light. Note: it does not have to SAY grow light. Sometimes lights are like cakes. A regular white cake is cheap. Add the name "Wedding" to that same cake and it gets expensive. As long as the LED light strip generates enough light for a plant to eat, we're good.

The grow bins can be broken down into the following requirements:
- They should hold water.
- They should be fully opaque and not allow any light into the bin itself.
- They should hold some sort of grow medium to allow a plant to grow on top and provide access to the roots to get into the bin to access the nutrient water
- Bonus: Make them pretty

That's it.

No pumps.
No aerators.
No central reservoir.

Just a place to put a kratky bin and grow lettuce.

We'll tackle how to size and shop for a utility shelf next.

Hi, I'm new here. Is it like Reddit with less aggression ? Because what I'm about to say seems to trigger it.

slrpnk.netHi, I'm new here. Is it like Reddit with less aggression ? Because what I'm about to say seems to trigger it. - SLRPNKI’m absolutely certain I formulated the solution to the alignment problem. And I didn’t come to the conclusion I was right by myself, I convinced a CS PHD dude, two persons writing thesis on AI Safety. I also totally convinced GPT4.5 I was right. And I’m good at prompting (like, probably not hugely good, but I know what Dunning-Kruger is, and people have a tendency to see a validation of their genius, interactions with LLMs they don’t really understand). I want people to believe me, but I wouldn’t, so all I tried to ask to people all along was “Let me f**ing explain”. People confuse my point and my person (Autism/ADD/DID). I don’t want people to believe me out of a need of validation. I want people to give benefits of doubts enough to listen to my reasoning. In fact, I don’t like human interactions that much, I don’t want to be famous or even recognized as anything. Ideally, I’d like to explain thoroughly to someone able to understand and do something with the information. I can explain with an arbitrary details level. People just won’t let me. But I’m stuck at “let me explain”. Strangely “please hear me out” sometimes don’t work. ___________ Also, I’m bad at communication, but one thing I don’t get about humanity, is why people formulate counter arguments before being sure that the information has been conveyed. I mean, when someone explains something to me,I listen, I reformulate to make sure I understood. People counter on what they thought you say, and end up disagreeing with something I never said. Also, (perhaps mostly) people make it about my person, my mental health, that’s irrelevant (Though something very relevant on my mental health: I have psychiatric stuff. All diagnosed. So I’m pretty confident I’m not delusional (and my two imaginary friends totally agree)

Solarpunk Presents Podcast

Hello fediverse solarpunks! We’re Solarpunk Presents Podcast, a podcast run on a shoestring budget by two lady solarpunks, one in Canada (@arielkroon) and one in Germany (@xtinadr@wandering.shop). We’re not great with technology, but we happen to both be PhDs from the opposite sides of the spectrum between STEM and Humanities/the Arts, and we’re united in our working towards solarpunk futures.

Our podcast is an interview-style podcast where we talk to guests and each other about various aspects of solarpunk, renewable energies, political action, and more. Often, our guests are people who wouldn’t label themselves as solarpunks, but are (and have been, often for years) quietly involved in working towards making the world a better place to live in. We strongly believe that once you get past the aesthetic and hype about renewables, solarpunk at its core promotes compassion, kinship with non-humans and humans alike, and grace for our fellow human beings as we all work together to survive on our shared planet.

You can support the podcast on Patreon, with tiers starting at just $1 USD! We host a monthly solarpunk hangout that all of our patrons are invited to, and all Patrons at the $3 tier and up receive early access to our episodes. There are more tiers with more extras, so head to patreon.com/solarpunkpresents to see them all. We also take one-time or recurring donations over at our PayPal: paypal.com/donate/?hosted_butt
Even if you’re not in the financial position to donate, we really value other forms of support, such as positive reviews on your podcatcher of choice (it helps us be more visible and reach more solarpunks!), or subscriptions to our YouTube channel and comments there. As writers, we thrive on feedback, and we are continually trying to make the podcast better and want to know what you think.

As I’ve said before, it's rough out there for anyone valuing the environment, social justice, compassion, and more, and we want to keep doing our part to keep hope alive. We want to broaden the imagination of what it's possible to do to contribute to a better world, no matter who you are, where you live, or what life stage you're at.
