Okay, hear me out, I was just looking at pictures of beavers and thought to myself, what if someone used a beaver dam for hydropower? I mean my first thought is of course that wouldn't work...unless? I mean I know nothing about dam construction or hydropower, so I can't actually disprove this to myself. Why wouldn't this work? Or could it?
Not sure if this is what you're talking about, but small-scale hydropower is definitely a thing and can be done fairly cheaply: https://youtu.be/1KyL1-0A0Gw
You're not going to generate enough electricity from a small damn to provide power to anything for more than a very small group of people though.
If society collapses and we haven't achieved communism I guess my plan is going out to the forest and living among the beavers
