Abstract: An energy conversion apparatus is disclosed adapted to convert any type of rotatable mechanical energy into electrical energy in an efficient manner which includes a plurality of generators positioned upon a rotating wheel of arms wherein the wheel is secured to a rotating drive shaft. Cylinders such as drums are axially oriented around the drive shaft and are caused to rotate in an opposite direction therefrom by a reversing gear system driven by the drive shaft. These cylinders include grooves therein which are adapted to receive a drive belt which extends outward along the individual arms to a pulley located on the rotor shaft of each generator.
