In energy storage, the principle of the flywheel can be used. Flywheels store energy in the form of the angular momentum of a spinning mass, called a rotor. The work done to spin the mass is stored in the form of kinetic energy. Video 1 is a simple video that illustrates the concept of flywheel electrical energy storage.
Flywheels are among the oldest machines known to man, using momentum and rotation to store energy, deployed as far back as Neolithic times for tools such as spindles, potter''s wheels and sharpening stones. Today, flywheel energy storage systems are used for ride-through energy for a variety of demanding applications
