    It’s slithly better the more dense the material, but that’s basically the same thing. You could say that depending on the location, using water is much more practical.

    A much more interesting one I saw was the molten salt ones, where basically you store the energy as heat in a sealed place, and then when you need it, you use that heat to run turbines.
