In what could be the most audacious clean energy plan this year, authorities in the US have approved Pacific Gas and Electric Company (PG&E) to generate solar power in space and beam it to earth.

According to a press release, the experimental technology uses orbiting satellites equipped with solar cells to convert the sun’s energy into electricity, which is then converted into radio frequency energy that can be transmitted to a local receiver station. Space-based solar power has been researched in the U.S. for several decades and this summer the Japanese government announced plans to pursue a space-based solar program.

According to this report, the 200-megawatt orbiting solar farm would convert solar energy collected in space into radio frequency waves, which would be beamed to a ground station near Fresno, Calif. The radio waves would then be transformed back into electricity and fed into the power grid.
