Space exploration and aerospace research

Technology that transmits electrical power through the air using microwaves to a distant receiver. JAXA demonstrated transmission of 1.8 kilowatts over 55 meters with high directivity control.

A proposed system for generating solar energy in space and transmitting it to Earth. The system would use satellites positioned approximately 36,000 kilometers from Earth equipped with sunlight-collecting panels and microwave transmission antennae.

A long-term JAXA initiative to develop technology for generating solar energy in space and transmitting it to Earth via microwave beams. The system would use satellites positioned in geostationary orbit equipped with sunlight-collecting panels and microwave transmission antennae.

A demonstration project by JAXA scientists showing the feasibility of transmitting electrical power wirelessly via microwaves. Successfully transmitted 1.8 kilowatts over 55 meters with high directivity control.
