California-based startup Aetherflux, working on transmitting solar energy from orbit to Earth, has announced a $50 million investment round. The funding will expand research into space-based solar power, with a strong focus on military and defense applications.
The company is developing technology to collect solar energy on satellites and beam it back to Earth using microwave or laser transmissions. This approach is seen as a potential alternative to ground-based generation — especially in scenarios where access to traditional power sources is limited or impossible.
Investors believe such technologies are particularly valuable for mobile army bases, remote facilities, and any scenario where autonomy and resilience are critical. In the future, Aetherflux also plans to expand into the civilian market, including remote areas and developing countries.
The project could mark a turning point in space energy development, transforming orbit into a new source of stable, round-the-clock power supply.
