Startup beams solar power from aircraft to Earth in breakthrough test

Overview Energy, a Virginia-based startup, has emerged from stealth mode after achieving a major breakthrough in space-based solar power. The company successfully transmitted energy from a moving aircraft to a ground receiver, proving key technologies for its ambitious plans. Founded in 2022, it now aims to beam solar power from orbit to Earth by 2030. The recent demonstration involved sending power wirelessly from an aircraft in flight to a receiver on the ground. This test validated critical hardware, including lasers and optical systems, which will later operate in space. The company’s approach uses low-intensity, near-infrared light to deliver energy safely to existing solar grids.

Overview Energy has already raised $20 million to develop a fleet of satellites in geosynchronous orbit. These satellites will collect solar power in space and transmit it to high-demand users on Earth, such as data centres, city grids, or military bases. Unlike traditional solar energy, this system could provide reliable power even at night.

The next phase includes a demonstration in Low Earth Orbit (LEO) by 2028. If successful, commercial energy transmission from geosynchronous orbit is planned for 2030. CEO Marc Berte emphasised that the system is being designed to meet real-world energy demands from the outset. The company’s progress marks a step toward making space-based solar power a practical reality. With $20 million secured and key technologies now proven, Overview Energy is moving closer to its goal of delivering continuous, reliable energy to Earth’s most power-hungry industries. Further tests in orbit will determine the system’s scalability and efficiency.
