ABSTRACT:
A vehicle drive system in which batteries provide power for driving an electric motor connected to a pump for either compressing air or pressurizing hydraulic fluid for loading a fluid cylinder that is operatively connected for reciprocatably driving a series of drive gears operably connected to and for providing rotation to a series of worm screw gears having an output shaft connected for driving the wheels of a vehicle. A kinetic energy recovery system in which a series of gravitational alternators are operably connected between the axle and chassis/frame of a vehicle for providing electricity during vehicular movement. Additional kinetic energy is recovered as steam is generated by deriving heat from the operative fluid cylinder to the screw engine and transmitting the heated fluid to a low pressure steam boiler for providing steam in operating a screw engine generator for generating electricity.
