SOUTH Korea's top technology university has developed a plan to power electric cars through recharging strips embedded in roadways that use a technology to transfer energy found in some electric toothbrushes.
The plan, still in the experimental stage, calls for power strips about 20cm to 90cm wide and perhaps several hundred metres long to be built into the top of roads.
Vehicles with sensor-driven magnetic devices on their underside can suck up energy as they travel over the strips without coming into direct contact.
"If we place these strips on about 10 per cent of roadways in a city, we could power electric vehicles," said Cho Dong-ho, the manager of the "online electric vehicle" plan at the Korea Advanced Institute of Science and Technology.
The university has built a prototype at its campus in Daejeon, about 140km south of Seoul, for electric-powered golf carts and is working on designs that would power cars and buses.
