A future concept transportation technology is being developed to provide all-electric vehicle recharging while traveling on the roadway for public and private vehicles, utilizing a renewable energy source. These vehicles will have the same range, power and maneuverability currently enjoyed by those powered with the internal combustion (IC) engine. The vehicles will have an electric drive motor (or motors) with minimal on-board energy storage (flywheel, capacitor, battery or fuel cell) as a reservoir when not in the range of the recharge network. The goal is to retain all the positive attributes of the IC-engine driven vehicles while eliminating pollution and dependency on hydrocarbon fuels. The recharge network is called the remote charging system for a vehicle, or simply the vehicle remote charge (VRC). This is a wireless power transmission system that replenishes the on-board energy storage system of a moving (or parked) vehicle with a microwave or laser power beam. The concept of transmitting electric power using a conductorless method has been in existence since the early 1900s. In the 1960s the idea was proposed to beam orbiting satellite-collected solar energy to the surface of the earth for use in the existing electric power grid. Hence utilizing a fully integrated network from satellite-collected solar power to on-board energy storage of a moving vehicle would entail a completely pollution-free, renewable energy transportation system for the country. Research in this field is an on-going effort, and the efficacy of wireless power transmission has been demonstrated in many tests around the world. A simple power transmission model demonstrates that the wireless power beam energy can be transmitted effectively to the vehicle, providing the necessary motive power to operate the vehicle.
