Understanding the Difference Between Energy and Power in Flywheel
In summary: Watts per second" would be the power output of a generator over a period of time (e.g. 5 seconds). "Watts" is a unit of power summary, the flywheel has a radius of 38mm, weighs 112.34g and has a angular speed of 89,011 rad/s. The flywheel has a moment of inertia of 0.5*m*r2 and generates 321 Joule of kinetic energy.
Flywheel Energy Storage System (FESS) | Energy Storage
Flywheel energy storage systems (FESS) use electric energy input which is stored in the form of kinetic energy.

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 to the system correspondingly results in an increase in the speed of th

Flywheel energy and power storage systems
Energy storage in flywheels. A flywheel stores energy in a rotating mass. Depending on the inertia and speed of the rotating mass, a given amount of kinetic energy is stored as rotational energy. The flywheel is placed inside a vacuum containment to eliminate friction-loss from the air and suspended by bearings for a stabile operation.
