Soon, electric cars to be powered through tyres

A team of researchers from Japan has come up with a method of sending electricity through 12 inches of concrete.

The technological achievement could see cars being recharged through special tyres that could charge up through the tarmac while being on the move.

The Toyohashi University of Technology has said that there are no technological hurdles to bringing ‘EVER’ – or Electric Vehicle on Electrified Roadway – to the roads, other than gaining mass-approval and adoption.

The team’s demonstration used the same concrete that is used for public roads in Japan, and showed electricity being sent through six inches of road surface.

In the demo, electricity between 50 and 60 watts had been sent to actual tyres, with a light-bulb lighting up to show how the electricity moved from the base, through six inches of concrete, and then into full-size automobile tyres, the Daily Mail reported.

Lead professor Takashi Ohir said that the concrete could be scaled up to 12 inches without a problem, although the voltage would need to be increased up 100 times in order to power a car.

However, Ohir said that this was not a technical issue.

He added that the efficiency of the power transmission through the concrete was 80 to 90 percent or higher.

Other companies that are looking at similar technologies are Toyota, which suggests a system of metal plates on the road.
