We need natural batteries like solar power lifting water from a lake into a reservoir so that when we need that energy and the sun isn't making it, released water does

A cubic meter of water above your roof has the storing capacity of a AAA cell. That's why you need huge, massive damms to store any significant amount of power. But unfortunately it's not flexible enough (you need mountains nearby) or dense enough.

What about storing energy as potential energy using some high density objects. This may work.. Right?? gravitricity Check out their work.
