Space-based solar power can be generated via a line of solar panels in a geostationary orbit, and then transmitted by wireless down to earth.
As there is no weather in space, solar power can be continuously generated there, so it is considered to be five to ten times more efficient than on earth.
That may sound like a fantasy, but it is one of the goals stated in Japan’s 2013 Basic Plan on Space Policy, and JAXA and private corporations are jointly conducting practical research to achieve it.
Japan seeks to realize its application by about 2030. One key technology in this endeavor is wireless power transmis-sion.
