Flywheel energy storage From Wikipedia, the free encyclopedia Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy
In inertial energy storage systems, energy is stored in the rotating mass of a fly wheel. In ancient potteries, a kick at the lower wheel of the rotating table was the energy input to maintain rotation.
