Recent Wireless Power Transmission technologies in Japan for space solar power station/satellite

Wireless Power Transmission technology via microwave (Microwave Power Transmission ; MPT) was advanced from 1960's and many researchers which had a dream to realize the Space Solar Power Satellite/Station (SPS). In Japan, many kinds of the SPS were proposed and designed in recent ten years. We will show the newest Japanese SPS and its characteristics. We also show some results of the recent Japanese MPT experiments, Ubiquitous Power Source, MPT for moving rover, Wireless charging system of electrical vehicle.
