the Space Solar Power System 宇宙太陽熱システム
———————-
Scientists all over the world are trying to find ways to make “green energy”, energy that is made from sources that don’t run out. Also called “green power”, it can be made from such things as the wind, the sun, and the movement of the ocean. Japan, however, has an idea, called the Space Solar Power System (SSPS), that seems like it is out of a movie. Sun energy will be collected in space, where it is five times stronger than on Earth. They will do this with dishes several square kilometers in size. Then, the energy will be sent to Earth. There are problems, though, like how to take everything to space and how to collect the energy safely. No one knows the future, but with time and luck, maybe Japan’s space agency will succeed.
