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

Today, flywheel energy storage systems are used for ride-through energy for a variety of demanding applications
Read MoreTL;DR - Because of how flywheel energy storage scales it is unlikely that significant efforts will be made to develop the technology for home use. This is similar to the case for windmills, where the power output increases as the square of the diameter, and the cube of the wind speed (which itself doubles roughly every 20m of elevation).
