Michigan-Based Startup Teams up with SpaceX to Explore Solar Power from Space
In a reminiscent nod to childhood activities, scientists are now testing satellites that could beam solar power from space. Michigan-based startup Virtus Solis is leading the charge, believing that this technology could unlock unlimited solar energy potential. Their partnership with SpaceX’s Starship is set to propel this innovative concept into reality.
Speaking at the International Conference on Energy from Space, Virtus Solis founder John Bucknell outlined the key components necessary for space-based solar power to succeed. These include heavy-lift launch capabilities, wireless power transfer, and cost-effectiveness. SpaceX’s promise of launching satellites into space for as little as $10 per kilogram provides hope for the project’s economic feasibility.
The plan involves using the SpaceX Starship to launch a solar array into a Molniya orbit, described by NASA Earth Observatory as an elliptical path that enables a satellite to orbit the same spot every 24 hours. The solar array would convert sunlight into microwaves, which would then be relayed to a ground rectenna for energy use.
Virtus Solis Chief Technology Officer Dr. Edward Tate explained that the rectenna, an antenna with added circuitry, could convert radio frequency into usable energy. This technology could potentially outperform traditional ground-based solar plants in efficiency.
Looking ahead, Virtus Solis aims to launch a demonstration satellite by 2027 and eventually deploy a network of 16 arrays to cover the globe. If successful, this project could revolutionize the way we harness solar energy on Earth.
