- Wireless power transmission is a technology that transmits power across space to a receiver device, which extracts power from the field and supplies it to an electrical load1. Conventional electric cables cannot be used to transfer electricity from the ground to space due to the huge distances and spacecraft velocities involved2. The only way to transfer power over long distances in space is by electromagnetic radiation2. Laser beam and microwave power transmission systems are currently the most promising technologies for wirelessly transmitting power over the long distance from a satellite in orbit to the surface of the Earth3. Scientists in Japan have successfully managed to transmit energy wirelessly with high accuracy, which could one day allow us to place huge solar sheets in space and beam the energy back to Earth4.
