My concept idea for a carbon negative solar azolla farm and vertical panel soybean farm

As per following all the rules, Rule 6, "AI-assisted posts must be labeled" so these images were generated using AI.

You have the solar panels protecting the lower ponds of azolla which don’t like direct sun. The solar panels provide excess electricity and power any machinery used to harvest the azolla. The azolla grows over TEN TIMES as fast as grass or any other plants, so you are cycling it rapidly producing truckloads of green biomass on a monthly basis.

I also added a concept image of a soybean farm with vertical solar fences. The idea being that you can harvest solar energy using very little horizontal space, while the plants still get full mid day sun.

What would be necessary for a public climate refuge shelter?

Hi, I am fantasizing the concept of public, free, periodically located structures that offer refuge from the extremes of climate. With worsening heat waves and bitter winters common moving forward, providing water, shade, temperature control, etc could be a matter of survival. What offerings should such a shelter provide? I want it to be in-line with the aesthetic and philosophy of solar punk so interested to hear ideas. In my view, solar punk party means constructing infrastructure for the good of people for greater sustainable alignment with their (now changing) environment. Ideally it would be powered by sustainable energy and could even serve to offer volunteer services like community courses. If we had a template for such a structure and placed them every X miles, there could be a network of these facilities serving the local community. This is a hypothetical at present, just considering ideas, thank you for inputs.

Solarpunk Permaculture in Tucson, Arizona, USA

Bro couldn't get people to understand, so he chopped up the city curbs himself to make rain basins, and then his neighbors followed suit, and then he ratted himself out to the city and THE CITY OF TUCSON MADE RAIN BASINS MANDATORY!!! A great example of Punk Activism changing the law! (even if he didn't know he was solarpunk, he's got the spirit.) https://youtu.be/lQ-jdUGCxcc?si=9KnsHDsz0cBC5zI1

"Solar punk won't exist if we don't try" altordo quote

I came across this company altordo. They live by solar punk ideology and let you build your dream solar punk housing online and help you by listing expenses. People that agree to those expenses will get their home built and set up by their design, the solar punk way.

Sadly this is now only available for the US, but are trying to go global. We as a community might be able to get them global.

Let me know what you think of this opportunity.

Solar USB Charger

I was asked for pictures of a solar usb charger that I made.

You can buy solar chargers that are as good or better than this one. The advantage this one has is that it is a 50W solar panel which means it has enough power to charge on cloudy days.

The components:

50W flexible solar panel nominal 12V (peak around 18V)

Flexible Solar Panel 50W 12V Monocrystalline Module Fiberglass Lightweight Charge for RV Trailer Boat Cabin Van Car Uneven Surfaces (50W-1)

Automotive cigarette lighter outlet

3 Pcs 18AWG Female Car Cigarette Lighter Socket with Bare Wire Open End Cable,1FT 12/24V Car Charger Power Cigarette Lighter Female Socket Replacement Cable for Equipment Within 120W

Do you know any false narratives about renewables injuring customers that we should watch out for?

I know fascists like the idiot liars at Fox News often point to renewables being supposedly harmful to the economy or supposedly harming the environment in manufacturing, however I haven’t heard anything from mainstream sources about renewables actually physically hurting individual customers.

What specific false testimonies actually would have started these rumors? I know it’s best to assume something as false when it comes from a fascist source, but I need to know the specific lies so I can fact check them properly and expose them.

I love the idea of solar ovens does anyone here have drawn plans I could follow to make my own diy?

I have a dish style solar cooker already which is great but I'd love to do more baking outside of the house especially with increasing heat waves

Solarpunk: A Short Guide to the Decolonization of the Sun

>In her book, entitled Solar Politics, Oxana Timofeeva makes the argument against an extractive cosmo-logic, in which not only the resources of the Earth itself are extracted (which would amount to an extractive geo-logic), but in which the Sun and the planets in the Solar system are now taken up by the capitalist economy. The Sun itself is only another nuclear fusion reactor.
And so, today, green capitalism is also a moniker for a new form of colonialism on a cosmological scale, in which natural resources are exploited for economic gain. The once free-giving economy of the Sun is reinstated into the capitalist economy of demand and offer.
Yet, solar politics does not suggest that we should return to worshipping the Sun, nor that we continue to extract from it. Solar power should neither be placed above or below the economy as such, but rather reconceptualized in the framework of an economy of free exchange.
How is it to be done?

Solarpunk Reality Check: Update on the bio-receptive "green bricks" one year later. (Spoiler: Not dead, just complicated)

Hey everyone! A while ago I shared an update here about the Swiss solar-rail project and how it holds up in real life. You guys loved the reality check, so today let’s look at another viral Solarpunk darling from about a year ago: The Dutch Bio-receptive Moss Bricks (spearheaded mostly by TU Delft and the startup Respyre).

The viral videos promised us cities where concrete walls magically turn into self-sustaining, lush green vertical forests using nothing but rainwater.

One year later, the initial internet hype has cleared, and the engineering reality has set in. Here is the actual status of the project:

  1. The "Moss doesn't just spawn" bottleneck

In the lab, it looked easy. In the real world, city smog, heavy wind, and intense UV rays mean that moss won't just grow on these bricks naturally from spores in the air.

The fix: They found out they have to pre-grow the moss in indoor climate labs for about 6 weeks before shipping the bricks to construction sites.

The reality: Right now, there is zero industrial supply chain for "living bricks." It adds months of delay to construction logistics.

  1. The 3-Month Blanket Problem

You can't just put these pre-grown bricks under the sun immediately. Current field protocols require that once the wall is built, it must be covered with a special light-blocking textile for 3 months. This acts as a shield to help the lab-grown moss acclimatize to the harsh outside world. As you can imagine, contractors aren't thrilled about covering new buildings in giant blankets for a quarter of a year.

  1. The Seasonal "Ugly Phase" 🍂

Instagram showed us vibrant, neon-green walls. Reality showed us that during dry summers, the moss goes into a dormant state, turning a patchy, brownish-yellow color. It only looks truly "Solarpunk" during wet autumns and springs.

The Good News: It actually cools!

It’s not all bad. The pilot walls (like the ones in Leiden and university campuses) proved the physics right:

  • The walls are 5–7°C cooler than traditional concrete during heatwaves.
  • They actually absorb massive amounts of particulate matter (urban dust).
  • Structure testing proved that the internal wall stays dry—the moss root-acids do not destroy the core building structure.

Conclusion: Where are we now?

The project did not fail, but it is officially out of its "residential house" phase. It is currently in an extended pilot phase (2025–2028). Instead of apartment buildings, they are shifting focus to urban infrastructure where aesthetics and construction speed matter less: highway sound barriers, retaining walls, and public bus stops.

It’s a classic Solarpunk lesson: turning our cities green is a slow, grueling battle of biochemistry and supply chains, not a 30-second TikTok miracle.

What do you think? Is a 3-month blanketed wall and brown summer moss a fair price to pay for a 6-degree cooler building?

hi, can you describe one prototypical solarpunk object ?

in cyberpunk, we have the face augmentation, usually one eye or two eyes which have fancy camera-corp made lenses with amazing technology to view things with a neon overlay showing computer generated text to show different things that are seen by the character

in steampunk, we have the steam overpowered vehicle, usually a flying ship or some kind of gadget bicycle / car which has a ton of tubes going all different parts to drive invisible engines which power multiple things in the vehicle

in biopunk, we have the synthetic / alien organism which can be either more powerful than an average human or make an average human into something much more powerful, sometimes as some kind of parasite or symbiosis

what would be a prototypical solarpunk object?

would it be the typical every day farm tool which seems to have some computer, hologram or mysterious functionality?

would it be the farm which is set in such a way that requires little to no special attention to produce crops?

what do you think ?

Our balcony solar storage market in Germany is getting wild

Just wanted to share whats happening in Germany right now because I feel like the rest of the world doesnt really know about it. We have this thing called Balkonkraftwerk which is basically a plug and play solar panel you stick on your balcony, 800W max feed in. Theres now like 3 million of these installed and the storage market is exploding because people realized they produce way more than they use during the day. The interesting part is the new regulations keep the 800W feed-in limit but panel input can go well beyond 2000W now, some systems take up to 5.000 Wp of panels, so with storage you can capture everything the panels make and use it at night. Brands are competing hard right now on capacity, cycle count, smart features. Some are doing 5kWh single units, others are modular. Its like the early days of powerwall but for apartments
