So hi #solarpunk people, i have a question: As a to become #Historian of #Technology and avid fan of "#low #tech" i want to know, which is the technology (or practice) you use from day to day you could imagine re-designed for a solar punk #future and how should it be different? I am less interested in #Software, but #tools, #hardware, #practices, #maschines etc. Any ideas? Suggestions? Please share!
@syndikalista Hydrogen fuel cells are going to be important to energy storage. A solar/hydrogen system also purifies water in the process.
@oorta how come that hydrogen is so much in your favor and not some other energy storage like compressed air storages?
@syndikalista Hydrogen can be generated by passing electricity from solar through grey water. In the fuel cell the hydrogen is recombined with oxygen to create electricty and steam. So, one system creates electricty, heat and purified water. It allows people to be autonomous from several utilities at once, and it recycles wastewater on site.

I can imagine solar cookers. I used them. Always worked with enough sun. Super simple to make.
@andrej i have no idea, if they would scale enough to supply a bigger environment. I mean, i have problems to imagine a peoples kitchen running with solar cookers, which would benefit the avoidance of foodwaste ect. But several energy sources combined? Why not?
I could imagine them scale for bigger kitchens, especially in parts of the world where the sun likes to shine.
Use bigger, or many solar concentrators (lenses or mirrors - which could be fairly 'low tech') onto big pans.
I've seen people use vacuum evacuated tubes (the 'proper' kit for solar water heating) for cooking. Filling them with food and leaving them in the sun.

@dazinism @syndikalista Yes, these setups actually exists. I heard about clinics in parts of Africa where collectors are used. I didn't find any references to it though right away. If you do a google image search you find some pictures of possible setups.
@syndikalista I had a hand cranked blender once that was pretty dope. Hand cranked flourmills (with an auger design) are also rad, but probably less practical for the average person. The nice thing about hand cranked tech is the ease of modification to pedal power.
@OmnaBrain well, i am not so much in favor for handcranked or personal-scale devices. Like grinding flour-mills, there is a reason community growth was connected to bigger integrated technological systems. blender is a different thing, but could be done with other energysystems as well (pressured steam, high-pressure water). :)
I worked on the design and construction of this stove.

Making #biochar, which has big potential for soil improvement and atmospheric carbon sequestration, while doing the cooking and space heating.
@dazinism this looks interesting. i guess i will take a deeper look into this design after my vacation
@syndikalista As a practice, using lightweight Linux distros to extend the life of old hardware is an easy one. Not #solarpunk, per se, but still helping to reduce waste and carbon footprints.
