A new experiment in China showed drones could one day be recharged mid-air using microwave energy transmitted from the ground.
During the trial, a car-mounted emitter successfully beamed energy to an antenna array installed beneath a fixed-wing drone, transferring power without physical connections.
The system enabled the unmanned aircraft to remain airborne for up to 3.1 hours at an altitude of 15 meters (49 feet).
