In a major breakthrough, Caltech scientists have successfully collected solar energy in orbit and wirelessly transmitted it to a receiver on Earth for the first time.

Overview Space has successfully tested a laser-based system for beaming solar power from the sky, a crucial step toward providing continuous clean energy from space.

Decades after it was first proposed, space-based solar power remains a distant goal, caught between its promise of unlimited clean energy and immense cost.

A new study reveals that the biggest hurdles for space-based solar power are not in orbit but on Earth, citing land availability for receiving stations as the main constraint.

A new documentary, “Bright Harvest,” showcases Caltech's groundbreaking Space Solar Power Project, which successfully beamed solar energy from orbit to Earth.

Aetherflux, a startup led by Robinhood's co-founder, has raised $60 million to develop a satellite system that beams solar power from space to Earth using lasers.
