Efficient storage of energy. The flywheel works through a heavy cylinder that is kept floating in vacuum containers by the use of a magnetic field. By adding power to it – e.g. energy from a wind turbine – the flywheel is pushed into motion. As long as the wheel is rotating, it stores the energy that initially started it.
Flywheel energy storage (FES) can have energy fed in the rotational mass of a flywheel, store it as kinetic energy, and release out upon demand.
