Electric power transmitted wirelessly in Japan

In a breakthrough, Japanese researchers have successfully transmitted electric power wirelessly to a pinpoint target using microwaves, an advance that brings space-based solar power closer to reality. According to Japan Aerospace Exploration Agency, or Jaxa, the researchers were able to transform 1.8 kilowatts of electric power into microwaves and transmit it with accuracy into a receiver located 55 metres away. In space-based solar power generation, sunlight is gathered in geostationary orbit and transmitted to a receiver on Earth. If implemented, microwave-transmitting solar satellites would be set up approximately 35,000 kilometres from Earth.
