One of the problems with switching to electric cars is the range of the vehicles per charge. But what if the roads themselves provided a constant charge, like a third rail?
Txchnologist (a news website that is presented by General Electric) reports on a concept from the Energy Dynamics Laboratory at Utah State University for roads that would charge electric vehicles as they drive on them:
"Electric vehicles, or EVs, could pick up small amounts of electricity as they drive over charging pads buried under the asphalt and connected to the electrical grid. Researchers say that a continuously available power supply would allow EVs to cut battery size as much as 80 percent, drastically reducing vehicle cost."
A Korean institute has recently developed a similar concept which it is developing to charge a bus system in Seoul.

Alternative Infrastructure: Electrified Roads
The concept is no different from trains travelling along a charged track. While any real-world implementation is a long way off, the TEV team is building a trial road for a lower estimated cost per mile than traditional highway.
