Abstract

A system and method for generating electricity from the movement of vehicles over a traveling surface is provided. In one embodiment, the system includes a stator having a plurality of windings, a rotor configured to rotate and configured to be mounted adjacent the traveling surface, the rotor having a perimeter and a plurality of magnets mounted to the perimeter and wherein each magnet creates a magnetic field and is mounted to the rotor so that the magnetic field of the magnets induces an electric current in the windings of the stator during rotation of the rotor, and results in an attractive force between the magnets and the vehicles moving over the traveling surface to urge the rotation of the rotor.

Claims
