Japanese group transmits electricity through 4-inch concrete block, could power cars on roads

The decision to invest in an electric vehicle would be much easier to justify if the car in question offered unlimited range. That appears to be the concept behind a Toyohashi University research group's wireless power prototype, which can successfully transmit electricity through a 10 centimeter-thick concrete block. During a demonstration in Yokohama, Japan, the team sent between 50 and 60 watts of power through a pair of concrete blocks to two tires, which then juiced up a light bulb (you can see the rig just above).
