You’ve heard of drivers having “road rage,” but how about “range anxiety?” Well that’s the term being used to describe owners of electric cars who nervously peer at the battery charge indicator on their dashboard to see if they have enough juice to get where they’re going. But now comes word that the Korea Advanced Institute of Science and Technology is working on a system that would embed transmitting coils in roadways, and put receiving coils in cars that would allow them to charge as they ride down the road. Such wireless power transmission isn’t a new idea and still has lots of kinks to work out, but it could eventually pull the plug on range anxiety and put some new zip in electric transport.
