An
electric bus that charges its batteries while driving (rather than while
sitting idle in a charging station) is no longer science fiction.
Researchers at Korea’s Advanced Institute of Science and Technology (KAIST) recently constructed a seven and a
half mile stretch of asphalt roadway in the city of Guami in South Korea with
specialized electric cables designed to power batteries on a moving passenger
bus.
The first of it’s kind technology doesn’t need the vehicles
to stop at a point to charge.
The bus’s batteries are equipped with a novel
technology called “Shaped Magnetic Field In Resonance” that sends
electromagnetic fields created by the electric cables buried in the asphalt to
the bus but not normal cars.
The technology recognizes vehicles capable of
accepting the electric charge and those that cannot.
A coil in the battery can turn the electromagnetic
fields into electricity at a distance of more than half a foot above the road.
