Patent ID: 7808121

Claim:
An energy efficient land vehicle, including a conventional land vehicle having land power means, and having at least one storage battery and at least one power consuming mechanism directly or indirectly connected to said at least one storage battery, for controlled delivery of electric power to said at least one power consuming mechanism, the improvement comprising: a supplemental electric power generation system located on said conventional land vehicle, said supplemental power plant including: i.) a housing; ii.) at least one set of rotatable blades mounted within said housing; iii.) a movable shaft connected to said at least one set of rotatable blades; iv.) a generator for generating electricity connected to said shaft; v.) a voltage regulator; and, vi.) a connection to said at least one storage battery for providing electric power thereto; wherein said housing has at least an open front for air ingress and an open area downstream from said blades for air egress, and said open front has at least one gate, said at least one gate having an open position allowing air to drive said at least one set of rotatable blades, and having a closed position preventing air to drive said at least one set of blades, and gate control means adapted to maintain said at least one gate in the open position when said vehicle is at rest and when said vehicle is moving during deceleration, and adapted to maintain said at least one gate closed when said vehicle is moving at a fixed speed and when said vehicle is moving during acceleration; such that when said vehicle is decelerating and said at least one gate is open, said rotatable blades are moved by wind speed created by movement of said land vehicle, said shaft rapidly rotated causing said generator to impart electricity through said voltage regulator, to said at least one storage battery, whereby said power consuming mechanism is indirectly powered by said generator so that electrical load on said storage battery is reduced.
