A US company, Aetherflux, is developing a revolutionary space-based solar power system. Funded by a $50 million investment, the project uses modular satellites in low Earth orbit to collect solar energy and transmit it to Earth via infrared lasers, unlike previous microwave-based concepts. A test launch is planned for 2026 with SpaceX. This technology aims to provide clean, reliable energy globally, sparking an international race in space-based solar power with competition from China and the European Space Agency. The US Department of Defense supports Aetherflux, highlighting the strategic importance of this technology.
