The rapid rise of the electric car still faces a substantial obstacle that keeps many people from buying them: their limited range. Nobody likes the risk of stalling on the highway after the car battery runs out. The UK government wants to solve the problem with a wireless power-transfer technology that it hopes to build under British motorways. The government has announced that it’s testing the technology that could someday let electric vehicles and hybrids “refuel” while driving. Charge-as-you-drive technologies have already been pioneered in South Korea. The wireless charging technology works by a process called Shaped Magnetic Field In Resonance. Electric cables buried under the road are used to generate electromagnetic fields, which are picked up by a coil inside the device and converted into electricity.
