Beschreibung
Zusammenfassung:	An electrically operated vehicle in which a battery provides energy for driving an electric motor coupled to a pump for pressurizing hydraulic fluid that is transmitted to a hydraulic motor transmission comprising either a worm screw gear or rack gear with each end operatively connected to a piston inside a cylinder having a chamber for receiving pressurized fluid providing power for reciprocatably driving either a worm screw gear or a rack gear to operative elements for providing rotation to an output shaft operatively connected either to the axles or the differential of a vehicle. Provision is also made for the recovery of kinetic energy by the application of a series of wind generators and a series of gravitational generators responsive to vehicular movement. Additional electricity is generated by connecting a second hydraulic motor transmission to a series of alternators arranged for supplying electricity to the principal battery source for electrical power for driving the vehicle and also to a second battery source for driving the second hydraulic motor.
