Researchers at the Department of Energy’s Oak Ridge National Laboratory last week announced they've managed to transfer 120 kw of power at an efficiency of 97 percent—more efficiently than any currently available physical charging connection. A version of the 20-kw wireless charging system that the same laboratory previously designed... Wireless charging could widen efficiency edge over cords, suggests DOE lab
