Abstract
A system and method are described for powering a vehicle using radio frequency (“RF”) signals. For example, a method according to one embodiment of the invention comprises: positioning a plurality of RF generators beneath the road surface of a roadway, the RF generators configured to transmit RF signals in the direction of vehicles traveling over the roadway; coupling a rectenna on a vehicle, the rectenna configured to receive the RF signals transmitted from the RF generators and to generate power from the RF signals; and using the power generated by the rectenna to power the vehicle.
