That's dope. Nothing quite like that. It's like how bicycles are ~99% efficient; just one of those weird, archaic things you would never expect to work as well as it does.
Only thing I’d say is that it’s probably not that scalable for grid storage. Like, they would take a lot more resources per watt to make en masse than, say, a pumped-hydro reservoir. All you need is one pump and one turbine, basically.
That’s why batteries and things like that haven’t really become a part of grid storage. We just need to store a LOT of energy. Lithium-ion batteries are efficient, sure, but they just take so many resources and so much labour to make per watt of storage, that they just can’t compete with a big lake hahaha
So cool. My friend's dad has like an antique car that has one of these in it to save momentum energy when you're coasting/decelerating. Just such a wild concept haha

Wheels are already the common tech for overflow storage (which isn't the same as general storage, but proves the concept)
