Pumped water storage is kinda a gravity battery, and it's currently the largest stored energy source for most countries.

    Yeah, they mention it in the vid. It's the exact same principle, but this way you can do it anywhere without needing a large body of water near by.

    Watched the vido now. Seems these gravity battery facilities might not be as efficient (80% to pumped hydro's 90%), but you can construct them anywhere, and don't need a mountainous land area nearby. Nice.
