It's exactly like gravity batteries, but do get fooled with fancy renders and inspirational music.

Lol that's great, and I was more talking about the ones for mines that already have deep holes, this one is hilariously stupid though. Water does make a lot more sense though, only issue I can see with it would be evaporation.

It's easy to use closed tanks. Mines are still a good site for energy storage, but using water instead of weighted sleds still makes more sense. Simpler over all system.
