An energy-producing system comprising an axle configured to be driven by an electric vehicle's wheels when in motion. The axle supports a series of wind-catching cups contained within an aerodynamic housing configured to direct air to the cups while also increasing the air speed. During vehicle motion, the cups are acted upon by rushing air causing the rotation of the axle such that the rotation may be transferred into energy via a generator/alternator linked thereto. A series of similarly polarized magnets integrated on said cups and/or spacers and/or housing proximate thereto further maintain the axle in motion during short vehicle stops. The system extends the life of the batteries between charges as well the distance the vehicle can travel between charges. A power controller is configured to distribute power from said generator to an axle drive motor, vehicle drive motor and/or start-up battery pack.
