Abstract: A diesel engine with an associated rotary pump pumps a fluid in a path of travel. A linear cylinder motor oscillates a disc. First and second multi stage cylinder pumps with associated attachment members operate in response to the movement of the disc. A hydraulic motor with a generator and pressure tank has a line for feeding fluid. An electric motor with a pressure tank and lines feeds fluid from the multi stage cylinder pumps to the pressure tank and feeds fluid from the pressure tank to the generator for powering the generator.
