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?
I have no idea how beaver dams work, this was pretty much just a shower thought. I assume though the beavers are living in dry areas and the turbines would go in the water where the beavers are not.
