Kinetic energy has been the energy well known since ancient times. The generator with a flywheel is an electric power amplifier that stores electric power and is made to generate large electric power at the short time, and used to be in a nuclear fusion institution. In recent years, the flywheel has been recognized an electric power tool for power stabilization. An example of application in the industry and in an electric power community is introduced. In addition, a characteristic application is developed despite the fact the energy efficiency of compressed air energy storage is generally poor.
