South Korea has switched on a road that can recharge electric vehicles as they drive along it. The project’s developer says the 12km route is the first of its kind in the world.
It means vehicles fitted with compatible equipment do not need to stop to recharge and can also be fitted with smaller-than-normal batteries. Two public buses are already using the technology and there are plans to add 10 more by 2015.
A device fitted to the bottom of the buses receives power from the road using a technology called Shaped Magnetic Field In Resonance.
However, another transportation expert warned that the costs involved in installing the equipment meant it was less practical than other schemes that involved vehicles wirelessly charging at specific locations or using overhead cables.
