A technology that wirelessly transmits electricity to cars driving along concrete roads may encourage more consumers to embrace gas-free EVs.
Fear of running out of?juice while out and about has limited adoption of all-electric vehicles, according to the Detroit Free Press. Sales of the Nissan Leaf, for example, plummeted 69 percent in June from a year earlier.
Researchers at Toyohashi University of Technology in Japan recently demonstrated a proof-of-concept version of wireless technology that transmits electricity to a car?s tires through four inches of concrete.
The tires have steel belts that then?route the electricity to a battery or straight to the engine.
For now, the group is able to transmit 50 to 60 watts of electricity to life-sized automobile tires, enough to power a light bulb.
The electric power needs to be increased 100 times in order to be practical. Such a scale-up is technically and economically?feasible, the group noted.
The team presented the EVER project (electric vehicle on electrified roadway) at the Wireless Technology Park 2012 trade show earlier this month in Japan.
