Found a cool book Called "DIY Solar Projects". Has some good info on PV solar but the big thing is the book has incredible build guides for passive solar ovens along with passive solar water and air heaters. Also has one of the best guides I've seen to build a solar still. #solarpunk

I've been wanting to do more builds like this mainly because I see the power in passive things. I use solar PV because it's one of the few non fossil fuel powered energy production sources. Ideally I would want all of my systems to be passive or powered by the sun/environment.This stuff needs to be built more often, and more research needs to be done to make these alternatives the standard in a post fossil fuel (and I would argue post capitalist) world. All of this with the idea that we should recycle and reuse these materials instead of wasting it.To build a truly sustainable future we have to look at alternatives that not only decouple from the fossil fuel loop, but also require less resources and less technological constraints. All of these can be made with salvaged parts.There are ways to generate electricity with similar methods. Some are close to being entirely passive. So we could decouple from both fossil fuels, and from the need of highly extractive practices. These systems aren't accessible to most people, but they should be, and free.The passive alternatives mean breaking from the fossil fuel system, and cutting down on extractive practices required by higher tech methods. Regular people can make these things and don't have to rely on technocratic structures or crumbling supply chains. These passive systems can be made locally by people, with the things around them. And that builds autonomy and resilience with sustainable practices like coppicing, or using plastic waste and using that to build passive systems, stopping plastic from going to the landfill. This means we can make a post scarcity, post fossil fuel, post capitalist world happen from the bottom up. Taking the infrastructures of our lives away from states and corporations and giving them back to the people, while making less impacts to our ecosystem around us.
