The Japan Aerospace Exploration Agency and the University of Fukui are jointly promoting the development of a device that can efficiently convert sunlight into laser light in space and transmit it to the ground. Once this device is completed, it is expected that it will not be affected by weather and time periods to achieve solar power generation. According to a report by the Japan’s “Yomiuri Shimbun†website, the research team is developing a large mirror-like device about 200 meters high and about 2 kilometers wide, and it plans to launch it to an orbit of about 38,000 kilometers from Earth. This device contains a new material developed by Jinbian Fukui, an associate professor at Fukui University. It easily absorbs the energy of sunlight and stimulates the generation of laser light. According to reports, after completion of this space-based solar power plant, the ground facilities receive the laser and use it to generate electricity. Its power can reach approximately 1 million kilowatts, which is equivalent to the power generation capacity of a nuclear reactor. The Japan Aerospace Exploration and Development Agency plans to launch test devices between 2025 and 2030. At present, there are two ideas for ground-based solar power generation. One is that photovoltaic panels directly convert sunlight into electricity; the other is that concave mirrors gather the heat of sunlight and heat water vapor to drive turbines to generate electricity. Their common defect is the large area of ​​land, which is also subject to sunshine hours, which can not generate electricity at night, and is extremely inefficient when the weather is harsh. If satellites are equipped with solar panels for space power generation, it is difficult for energy to be efficiently transmitted back to the ground. Compared with natural light, the laser has very little divergence and great energy density. It is considered to be the best medium for transmitting energy between heaven and earth. Japan has been researching this field for many years. In 2007, the Japan Aerospace Exploration Agency and Osaka University announced a breakthrough. They used a chrome-bismuth hybrid powder to absorb sunlight and stimulate laser emission.
