How do flywheels store energy?

It follows on from these basic laws of physics that a flywheel will store more energy if it has either a higher moment of inertia (more mass or mass positioned further from its center) or if it spins at a higher speed. Water wheels use the simple flywheel principle to keep themselves spinning at a steady speed. This is a model of an

How Energy Storage Works

Flywheel Energy Storage Systems convert electricity into rotational kinetic energy stored in a spinning mass. The flywheel is enclosed in a cylinder and contains a large rotor inside a vacuum to reduce drag. Electricity drives a motor that accelerates the rotor to very high speeds (up to 60,000 rpm). To discharge the stored energy, the motor
