Last month, JAXA demonstrated wireless microwave transmission of solar power in space by beaming 1.8 kilowatts of electricity via microwave transmission 55 meters to a pinpoint target on a receiver.
In the late 1970s and 1980s, the U.S. Department of Energy and NASA jointly investigated the concept of space-based solar power under the Satellite Power System Concept Development and Evaluation Program. In 1999, the Space Solar Power Exploratory Research and Technology program (SERT) was created by NASA to study the feasibility, design, and requirements of space-based solar power.
"When space solar energy becomes our main energy, people will no longer worry about smog or the greenhouse effect," Xiji said.
