Stanford University researchers believe they've found a better
way to build a long-range electric car. Amazingly, their
solution has nothing to do with batteries. By using resonating
metal coils to wirelessly transmit large amounts of current
between roadways and vehicles, the researchers say it's now
possible for an electric car to have virtually limitless range.
Using magnetic resonance coupling, coils in the roadway could
wirelessly transmit power to electric cars cruising down the
highway. (Source: Stanford University) "The idea is that the
energy transfer would take care of the base load that you would
need to propel the car," Sven Beiker, executive director of the
Center for Automotive Research at Stanford (CARS), told us. "If
you do the math, you see that it would provide enough energy for
the car to cruise down the road at about 65mph." CARS's idea is
to use a concept called magnetic resonance coupling to transfer
the energy. A resonating coil in the roadway would be connected
to an electric current,
