There has been a great deal of debate on electric vehicles and their distances traveled between recharging, the availability of recharging stations, home or commercial, and whether the electricity provided is “Green renewable energy” or electricity created by burning fossil fuel. The invention uses wind energy and the Gemini Electric generator to produce free electric energy. I can hear the argument that if the wind does not blow no electric energy is created, but when used on a electric vehicle, every time the vehicle is moving air passes over the vehicle. For example a vehicle traveling at 60 kph there is a 60 kph air flow traveling over the vehicle, and at 110 kph there is a 110 kph air flow traveling over the vehicle. Now you might argue that a propeller type wind turbine can not operate in high wind speeds. But the Ettridge Wind turbine is a Savinius rotor wind turbine that is not limited by the wind speed, it achieves its performance by using overhead air scoops to direct air passing over the turbine, down onto the moving blades beneath for the full 360 degrees, creating much more usable torque. By mounting the Gemini electric generator in the center of the Ettridge Wind turbine and positioning the wind turbine on the roof of a vehicle or behind where the radiator would have been positioned a serious amount of electricity can be generated and fed into the battery or directly into the electric motor. It should also be noted that if the vehicle is stationary and a strong wind is blowing, if the vehicle is positioned facing the direction of the oncoming wind the wind turbine will generate an electric current which can be stored in the vehicle’s battery.
