One of my neighbors is principal engineer in a company that is making flywheel technology uninteruptible power supply devices. I don't remember the specifics, but from when the power is shut off, the UPS flywheel will power a big computer server for like 48 hours. All on a flywheel spinning away in a vacuum. I remember reading about this as conceptual stuff in Scientific American over 30 years ago.
