Technology for a Solar-Punk future.

Hi, I've had some good discussions here in the past, so I thought I'd reach out with an idea for a resource I'd like to try to put together for solarpunk writers and artists.

I was talking with A.E. Marling about a story he's working on, and one of the things he was looking for was uses for old cars.

I think the obvious answer you'll get from solarpunks (aside for limited use where it makes sense) is to melt them down for your society's steel manufacturing needs - electric arc furnace smelters running off a green grid, recycling, are about as close to zero emission steel as you're likely to get, and the metal is already refined so I think you could get pretty tight control over the quality on the output.

But I think reuse offers some much more interesting opportunities. I'm only just starting to learn about fixing cars, but I've already been struck by the fact that at least some parts in cars can go into other things. For example, it looks like certain old alternators can be used to generate a wide range of amperage and voltage, suitable for different needs, including welding: https://diysolarforum.com/threads/diy-low-cost-generator-from-vehicle-alternator-alternating-generator.1843/ so perhaps one could be hooked by belts (adjusting speed) to a waterwheel or something?

I feel like a solarpunk society with a really strong library economy might start cataloguing parts of more complicated machines (even salvaged from machines like cars).

And looking for parts commonalities and alternative uses strikes me as a really cool step towards building an open-source manufacturing sphere. Perhaps starting with a database of hardware/parts so they could be identified and repurposed, and alternatives identified.

So the actual proposal:

I'd like to try and put together a list of common car parts which can be reasonably used in other (more solarpunk) contexts. This doesn't have to be specific down to the model number or include a how-to guide, (though I recognize that some reuses might only be possible with a specific model) just something solarpunk writers could casually drop into a description of a room or workshop, or an artist could put in the background of a scene. Something that shows that this isn't a scratch-built future, but that they're repurposing stuff where they can. Think of all the weird ways postapoclyptic movies dress the sets with misused items from the present - we could offer something like that to solarpunk, but grounded in at least some practicality. If you have any suggestions, I'd love to hear them.

Thanks!

edit: I've built out a list and it's located over here: https://slrpnk.net/post/13032570

This is a great list with a bunch of stuff I wouldn't have thought of - the transmission reuse is a cool idea!

I think some LED headlights are goood for growing plants. I remember some local news panic piece from years ago about how criminals were stealing headlights for their grow ops. A quick search online confirmed they work fine (probably not worth stealing though) and this post I think suggested a couple other car parts alternative uses I'll have to go back and get later: https://www.rollitup.org/t/is-it-possible-to-convert-a-headlamp-into-a-grow-light.496815/

Thanks again!

Yeah, if you watch a video on old water powered mills, they had all sorts of transmissions built out of wood, including clutches to turn on and off the power.

The headlight thing is really cool
