The rotor assembly includes a plurality of spokes (20) emanating from a central rotational axis (26), with high-performance magnetic coils (22) mounted on the outer end portions of the spokes. The rotor assembly (12) is drivingly connected to AC/DC generator (32), the output of which is routed to a power transfer switching unit (40) which outputs electricity as either AC or DC and at various desired voltages. A programmable system controller (24) controls the polarity of the magnetic coils (22) mounted on the ends of the spokes (20), as well as the operation of the generator (32) so as to power and constantly change the polarity of the magnetic coils as the rotor assembly rotates, thereby to cause the rotor assembly to rotate by virtue of interaction with the Earth's magnetic field.Type: GrantFiled: May 14, 2014Date of Patent: July 4, 2017Assignee: Wahoo Energy LLCInventor: Benjamin M.
