According to a report from the Japan Times on May 27, 2014, JAXA has been exploring the concept of large-scale solar sails for space-based power generation. This ambitious project is part of a broader vision for space-based solar power systems (SSPS), which aim to harness solar energy in geostationary orbit and transmit it back to Earth. The core idea behind SSPS is to construct massive solar power stations in space that can collect sunlight continuously, convert it into electricity, and then beam it down to Earth using microwaves or laser beams. Unlike terrestrial solar farms, these systems are not affected by weather or day-night cycles, making them highly efficient. In fact, their potential output could be 5 to 10 times greater than that of ground-based solar installations. A single SSPS measuring 2.5 kilometers by 2.3 kilometers could generate up to one gigawatt of power—equivalent to a typical nuclear power plant. Japan has been focusing on developing key technologies for building large structures in space, as well as methods for safely transmitting energy to Earth. JAXA is also working on ways to fold and launch solar sails using rockets, with plans to deploy them once in orbit. The agency initially aimed to conduct space-based demonstration tests by 2017 and begin commercial operations by 2030. However, due to various challenges, this timeline has become increasingly unrealistic, and JAXA is expected to announce revised goals in the near future. One of the biggest obstacles remains cost. JAXA estimated the total cost of building an SSPS at around 1 trillion yen (approximately $9.83 billion), but experts believe this figure is far too low. The scale of such a project is enormous—JAXA’s proposed design would weigh 26,600 tons and be 750 times larger than the International Space Station. Launching all the components would require numerous space missions. With Japan's current H-2A rocket capable of carrying only 5 to 6 tons per flight, and each launch costing about 10 billion yen, the financial burden is staggering. Additionally, there are concerns about the safety of microwave transmission and its potential impact on the environment and human health. If Japan were to use lasers instead, the system could be smaller, but lasers would not work effectively through clouds, limiting their reliability. Despite these challenges, the vision of space-based solar power continues to attract attention as a promising solution for sustainable energy in the future. With ongoing research and technological advancements, it may one day become a reality.
