ABSTRACT:
A passenger car deriving all or a part of its motive power from the wind through a system of one or more rigid vertical airfoils symmetrically aligned with respect to the fore-and-aft axis of the car. The relative wind velocity acting on the airfoil system under typical conditions produces a force tending to propel the car forward. The production of this sailing force occurs automatically, without requiring any adjustment of the airfoil system. The sailing force can be increased by having a tall airfoil system, which retracts to a lesser height for convenience in garaging or for safety in high winds. The wind-derived sailing force can significantly improve the fuel economy of a car using this invention, and in some applications of the invention, it can enable the car to cruise at a respectable speed in average wind conditions on wind power alone. When the car is traveling at speeds less than the maximum speed obtainable from the existing wind conditions, the excess wind power can be used to charge an energy storage device, from which energy can later be withdrawn as required to propel the car in periods of insufficient wind or when greater acceleration is desired.
