Imagine an electric car that charges up as it’s zooming along the highway. The road is the charger, able to wirelessly transmit power to a vehicle while it’s in motion. This vision could be a step closer thanks to work by Stanford University researchers, who have come up with a new way to transfer power to an appliance even as it moves away from the source. The team, led by Shanhui Fan, showed that they could provide continuous wireless power to an LED light bulb while they moved it away from the power source, up to a distance of about one metre. They published their results in Nature.
