Transmission of electricity through a concrete block to Auto Tires

Team of researchers with demonstration

A team of researchers from Japan’s Toyohashi University of Technology have successfully transmitted electricity through nearly 4-inch thick concrete block using wireless power transmission technologies based on electric field coupling (i.e. inductive coupling). In a demonstration at the Wireless Technology Park 2012 in Yokohama, Japan, which ran from July 5-6, the team transmitted between 50 and 60 watts of power through a concrete block to the two tires that was able to light a bulb.

This project is called as EVER (Electric Vehicle on Electrified Roadway) that could be used in future to recharge the cars through a constant stream of electricity from the road i.e. inductors.

However, there are difficulties which still needs attention such as transmission of 100 times of electricity through a thickness of twice (as has been demonstrated) as reported by Takashi Ohira, professor at the university’s Department of Electrical and Electronic Information Engineering, who leads the research group.
