Gravity batteries aren't exactly a new idea. You can store energy by lifting something heavy, converting kinetic energy into potential energy. To get it back, you let the mass fall and convert that motion to electricity. [Valeriamayara22] shows how to

There's a line in a [Weird Al] (no relation) song that says, “I upgrade my system at least twice a day…” I know how that is.
