I have a generator but I’m concerned about being able to get fuel in a crisis scenario

Meh. Just hook it up to an exercise bike. :-P

I know it would not be practical, but my mind just wandered into an idea regarding storing kinetic energy from solar cells. Imagine some huge concrete blocks or rocks attached to a chain connected to a drive at the top of a tree that drives a generator. During the day, the solar powered motor cranks them up to the very top. Then, at night, as you use power, they drop, spinning the generator, supplying power kinda like the weights of a cookoo clock.

I suppose you wouldn’t get all that much power out of such a thing though, unless you had a tree a couple miles high.

It also sounds kinda rube goldbergish...

lol I’m too old and fat to get on a bike for too long :D

There are some pretty nice flywheel setups available to store kinetic energy as an alternative to batteries, but it’s going to be more expensive.

Iirc, there’s pumped hydro storage. Same principle but with water.

No. It actually sounds like Neal Stephenson giant millennial clocks in “Anathem”
