In recent years, China has been at the forefront of space solar power research and development. A space solar power system is a way to collect solar energy in space and then convert it into electricity that can be used on Earth. nnThe advantage of a space solar power system is that it can collect solar energy 24 hours a day, 7 days a week, and 365 days a year. China successfully tested a space solar power system in 2016, and more recently in 2022 and since then, the country has been working to commercialize the technology. Space solar power system has great potential to meet the growing demand for clean energy on Earth. nnHowever, the technology is still in its early stages of development and faces many challenges. For example, a space solar power plant would need to be very large to generate enough electricity to be economically viable. In addition, space solar power plants would need to be located in geostationary orbit, which is 36,000 kilometres above the Earth's surface. The high altitude would make the construction and maintenance of space solar power plants challenging and expensive. Despite these challenges, the space solar power system remains an exciting potential source of clean energy for the future.
