A drive system moved by the power of repelling magnets causes a big wheel to rotate. The big wheel induces the rotation of a smaller wheel, connected to the shaft of an alternator (if we want to obtain obtaining an a.c. current) or a generator (for a c.c. current) which, through a forced rotation, produces electric energy. This is a maximum simple and cheap system which produces alternating
