Electric car recharging | |||||||||||||||||
Beginning with "Diamond," or HOV lanes; a miles-long linear electromagnet is imbedded in the middle of the lane; hybrid and all-electric cars have a pickup coil installed underneath the chassis, so that the batteries are recharged by the underground electromagnet as they drive over the recharging lane. (This technology exists as "inductive power transfer," and is already a mature industry). The only real obstacle (after paying for the installation, of course) would be determining how to charge motorists for recharging, I'm thinking road use tolls collected electronically and billed to motorists.

One question would concern the energy losses in the creation of the required magnetic field.
Another would be whether the energy received by the car would exceed the energy expended while driving over this magnet. If so there would be no net charging of the automobile battery.
In a way, this is a variation on the third rail concept used by city subway systems, with the physical sliding contact replaced by a magnetic field.
WHY NOT HAVE CARS WITH WHEELS AND MAG LEVITATION SLIDES. THE CAR CAN TRAVEL ON GAS ON BATTERY POWER OR MAGNETIC LEVITATION. CARS CAN RUN ON GASIN THE CITY- ON BATTERY POWER IN NON-POLLUTING AREAS- ON HIGHWAYS MAGNETICLEVITATION.
