Vehicle-mounted generator

A vehicle-mounted generator for improving fuel efficiency of a motor vehicle having a drive train comprising an internal combustion engine that drives a transmission connected to a drive shaft, said generator comprising:

• a rigid cylindrical housing forming an enclosed interior chamber, said housing having an inlet located on one side of a central longitudinal drive shaft for asymmetrically inputting wind into the interior chamber, and having an outlet located at a first end of the housing;
• means for mounting a second end of the housing to the motor vehicle in a position such that relative wind is directed into the inlet, said relative wind being produced by the combination of ambient wind and motion of the vehicle;
• a spiraling parabolic deck forming a floor of the interior chamber, said deck spiraling around the central longitudinal shaft from the second end of the housing to the outlet at the first end of the housing, wherein at the second end of the housing, the deck is aligned with the inlet;
• a turbine mounted on the drive shaft within the outlet for converting wind energy to mechanical energy as the wind passes through the turbine;
• an electrical generator connected to the drive shaft for converting the mechanical energy produced by the turbine into electrical energy;
• and
• means for supplying the electrical energy to recharge a battery that powers an electric motor connected to the transmission in parallel with the internal combustion engine.
