Abstract: An energy conversion device includes batteries and a DC motor. A rotary member is driven by a hydraulic pump, which acts through pistons engaging a eccentric U-shaped rod to impart torque to the rotary member. Bevel gears transfer the torque to the rotary member, which can be connected to a DC generator or a battery charger. The pistons include hollow piston head and piston rods, which reduce the amount of hydraulic fluid that must be pumped. This energy conversion device may be employed in a vehicle. Hydraulic fluid, activated steam or air may be employed as a working medium.

This energy conversion device may be employed in a vehicle, which may also employ a windmill as an auxiliary power source. Air is outlet from this windmill through hollow rotating windmill arms and through a hollow central shaft.

Abstract: A power system or an energy system conversion including a bank of batteries operatively connected to a converter or voltage multiplier. The voltage multiplier adjusts the voltage from the bank of batteries and directs an output voltage to a DC motor. The DC motor in turn drives a gear box which in turn drives a workpiece. In the course of performing work, energy associated with the workpiece is captured and directed back through one or more electrical components where the recaptured energy is stored or otherwise used by the bank of batteries. In one embodiment of the present invention, the energy recaptured from the workpiece is directed to an alternator which is in turn connected to a voltage regulator. The energy provided by the alternator is used to drive the voltage regulator which in turn produces an output that is connected to the bank of batteries.
