At team at Caltech recently successfully launched a space solar power technology demo which aims to study the feasibility of harvesting solar energy directly in space.
The hardware, which went up via SpaceX’s Transporter-6 mission, uses photovoltaic cells on it’s frame, and beams the energy back to earth using microwaves.
