All Electric for the Millennium - Mobile Vehicle Recharge 2000-01-1058

The development of a pollution-free transportation system for the millennium is provided by the recharging of a vehicle's non-polluting on-board energy storage unit (batteries, flywheel, whatever) as the vehicle travels unrestricted down the highway. This futuristic concept is called “VEHICLE REMOTE CHARGE - All Electric Vehicle Transportation via Wireless Power Transmission”. The MOBILE VEHICLE RECHARGE utilizes microwave or laser technology for the mobile recharging of an energy storage unit on a non-hydrocarbon-fueled vehicle as well as sophisticated guidance systems to track and guide the energy beam to the vehicle. Thus the system uses military technology in a commercial application.
The transportation system incorporates technology from both the automotive and defense industries to combine the two in a commercial venture. This benefits the economy and assures economic growth into the new millennium while providing people the freedom of movement and mobility they currently have with the internal combustion engine vehicle. This recharge system can be used with electric or hybrid-electric vehicles.
This is for both public transportation vehicles and private automobiles. The system can start out small in downtown areas with public transportation, then expand into suburban and even rural areas.
To date, the most reliable electric source, especially for city travel, has been overhead tethered lines or on-ground tracks in public transportation. But these greatly reduce the convenience of route changes and are at the mercy of small traffic pattern changes which can cause traffic tie-ups. The ideal electric bus would have a completely mobile energy source, such as a battery pack. But the limited range of a battery powered vehicle has restricted its use to only specific cases. In private vehicles also, the limited range of zero-pollution battery power has reduced the desirability of all-electric transportation.
The charging of these on-board electrical energy storage systems will take place via a wireless power transmission network that will be established along the roadside on existing power line (telephone) poles or new stand-alone poles that would be in conjunction with the existing poles. The idea of transmitting electric power using a conductorless method has been in existence since the turn of the century. Microwave and laser based systems provide wireless energy transmission.
There will be issues about the environment, safety, and government regulations that must be addressed. But technological advances with a discerning government can make this system a reality. These concerns will be discussed in the paper.
