Abstract: A vehicle electric power generating system may include an alternator communicatively coupled to a wind driven turbine and to the existing vehicle battery. A belt may be rotatably coupled to the alternator and the wind driven turbine respectively. A controller may be communicatively coupled to the alternator to automatically regulate the power transfer rate of the alternator. A plurality of sensors may be communicatively coupled to the controller and may be communicatively coupled to the existing vehicle battery as well as an existing vehicle electric motor. First and second switches may be intermediately coupled between the existing vehicle battery and the controller as well as the existing vehicle electrical motor and the controller respectively. Upon synchronous rotation of the wind driven turbine and the belt respectively, the alternator generates an electrical power output adapted to charge the existing vehicle battery.
