Vertical weight energy storage

Why don''t we use weights to store energy?

$begingroup$ @dotancohen Ignoring a few complications and efficiency losses, yup, almost. And you could gain extra efficiency from employing counter-weights, for example. Gravity is really, really weak - consider how easy it is for your puny chemical-powered body to counteract the force of the whole planet whenever you jump or walk the stairs (and a typical
