The present invention provides an air-wind power system for a vehicle having an electrically operable drive system. The system includes at least one battery which is mounted within an interior portion of such vehicle and which is connected to such drive system and at least one air-wind powered turbine which is mounted on the vehicle and which is electrically coupled to the at least one battery. The air-wind powered turbine has a propeller fixed in a vertical plane and mounted on a horizontally disposed shaft having an axis thereof being disposed perpendicular to a longitudinal axis of such vehicle. A rotational movement of the propeller caused by an air current enables the at least one turbine to generate an electric energy which is stored in the at least one battery and which is used by such drive system to move such vehicle in a direction of travel.
