This is like the gravity generators they're looking to use old mines for.

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.

That's my second favorite solution. One of the cons of the mines is they tend to be too remote from urban areas. But if that's not a factor then you're golden.
