Overview Energy is a startup working to harvest sunlight in space and transmit it to Earth, enabling solar farms to deliver power both day and night. The company plans to deploy large solar arrays in geosynchronous orbit (~22,000 miles up) that convert sunlight into infrared laser beams aimed at ground-based receivers co-located with existing solar facilities. A recent airborne test saw the system successfully send power across 5 km from a light aircraft to a ground receiver, demonstrating proof of concept. Future milestones include launching a demonstration satellite to low Earth orbit in 2028 and beginning megawatt-scale power delivery from geosynchronous orbit by 2030. By re-using existing solar farms, Overview hopes to sidestep the need for bespoke ground stations and reduce public-safety concerns associated with high-power beams. The company faces competition from firms pursuing microwave-based wireless power as well as falling grid-scale battery costs. Overview has raised $20 million so far to fund technology development, backed by Aurelia Institute, Earthrise Ventures, Engine Ventures, EQT Foundation, Lowercarbon Capital, and Prime Movers Lab.
