I wish someone would figure out a better flywheel.

  Limited by strength of materials.

    Interesting. Have you a reference? I had a friend working on industrial UPS systems that used large flywheels. Was years ago so I do not know the details. I think they could supply a lot of energy quickly (no start up time) but maybe not for long?
