A fly wheel is a rotating mechanical device for storing rotational energy, and rotates by receiving power from a driving source such as a motor. Since the energy stored in such a flywheel is proportional to the size and speed of the flywheel, the size of the flywheel can be increased to store a large amount of energy, which is accompanied by an increase in the output of the driving source that rotates the flywheel. will do

It may be provided by an energy production facility or the like. However, in the prior art, no technology has been proposed for more efficiently providing the energy of the flywheel to an energy load facility or/and an energy production facility.
