Electric Cars

A new wireless power system could help people avoid the inevitable jumbled mess of tangled cords and offer a more efficient way to charge electric vehicles on the go, according to a new study.

Researchers at Stanford University adapted a concept from quantum physics to produce a wireless charger that does something other wireless chargers cannot: automatically tune the frequency of the radio wave — the medium that transfers the power — to account for changes in the distance between the charging pad and the device.
