  1. Pumping water into a storage tank located at a higher elevation is another potential source of stored energy; pump it up while the grid is in surplus, and open the floodgates directed into generators when availability of power is otherwise low.

  2. As kids we hadron airplanes made of balsa wood. They had a small wind up propellor that you’d wind up with a rubber elastic band which ran along the length of the ‘fuselage’ from the back of the prop to the tail. I’ve often wondered if this concept couldn’t be employed on a massive scale for things like tractors, lawn mowers, golf carts, etc. using rubber as a source of stored energy. And what about large steel springs? Take the same concept from a Swiss watch with its miniature springs and flywheels and enlarge it.
