Abstract
The mechanism recharges the batteries of electric powered vehicles while the vehicle is in motion. As a vehicle moves forward it creates an air flow that enters the air scoop of the mechanism. The air flow passes through the air reduction tunnel and turns the wind blades of the mechanism which turns a drive shaft. The drive shaft has two gears, one turns a governor, the other turns an alternator that creates electric current that passes through a voltage regulator and on to the batteries that drive the vehicles motor. Air velocity entering the mechanism varies by the forward speed of the vehicle. A governor maintains the desired rpms of the drive shaft by changing the pitch (angle) of the variable pitch wind blades. A drain hole is located in the bottom of the base for moisture taken in through the scoop.
