Flywheels are good as a very short term buffer where you don''t do any conversion -- you store excess kinetic energy, and you dump it immediately back out as kinetic energy. But they just don''t scale. Same with capacitors. Great for what they do in the small, but they don''t scale up. The greatest returns have always been efficiency improvements

That is, it stores energy in the form of kinetic energy rather than as chemical energy as does a conventional electrical battery. Theoretically, the flywheel should be able to both store and extract energy quickly, and release it, both at high speeds and without any limit on the total number of cycles possible in its lifetime.
