Clean Energy From Space

Researchers at Caltech are turning a once-considered sci-fi technology into a reality — transforming collected sunlight from space into electricity and beaming it to Earth, to provide a global supply of clean and affordable energy.

"This is an extraordinary and unprecedented project," says Harry Atwater , an SSPP researcher and Otis Booth Leadership Chair of Caltech's Division of Engineering and Applied Science. "It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world."
