The Japanese Aerospace Exploration Agency and the Osaka Institute of Laser Engineering are planning to launch plates made of chromium and neodymium into orbit, which will convert 42% of solar light into lasers. These will shoot down onto a facility that converts the laser power into usable power. They claim that collectors 100 to 200 metres long will produce 1 Gigawatt of power. Unfortunately, they don’t expect it to be in production until 2030.
