Flywheel energy storage composition
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.
A typical system consists of a flywheel supported byconnected to a . The flywheel and sometimes motor–generator may be enclosed in ato reduce friction and.
TransportationAutomotiveIn the 1950s, flywheel-powered buses, known as , were used in() and() and there is ongoing research to make flywheel systems that.
