Flywheel energy storage devices could be looked at as a radical application of very traditional technology. They work by maintaining rotational energy by moving a flywheel. This same idea is used to keep a mechanical watch ticking.
A majority of modern FES devices use electricity to put the flywheel in motion, but some researchers are interested in the idea of using mechanical energy to start and stop the wheel. Read More →
