ABSTRACT:
A system is disclosed for storing electrical energy and for converting DC power to AC power. The system includes a very large flywheel which is mounted in an evacuated housing and is driven by a plurality of wheels powered by DC electric motors which receive current from an input power source. An independent plurality of wheels coupled to AC generators selectively engage the rotating flywheel to withdraw energy from the rotating mass of the flywheel in the form of alternating current. Control systems are provided for adjusting the radial position of the drive and output wheels in dependence upon the speed of the flywheel. Additional control systems are provided to change the number of driving motors or output generators in contact with the flywheel depending upon the input power available or output power required.
