US Patent 6838782 Wind energy capturing device for moving vehicles

A wind energy capturing device for moving vehicles including a wind turbine powered electrical power generator for installation on the roof of a moving vehicle such as a truck cab or tractor. The invention takes advantage of the powerful wind force generated by the vehicle moving on the road at moderate to high speed impinging against the wind deflector mounted on the truck cab or tractor. This otherwise “wasted” wind energy is captured and directed to the face area of the rotor blade, rotating the turbine, which, in turn, drives the generator to generate electricity. The electrical energy may be stored in a battery system and used to drive the motors of an electric vehicle or hybrid-electric vehicle.
