Space-sourced power could beam electricity where needed

Capturing solar energy in space and then beaming it down to Earth could provide consistent electricity supplies in places that have never seen it before. Should the as-yet untested idea work and be scalable, it has applications in IoT-sensor deployments, wireless mobile network mast installs and remote edge data centers.

The radical idea is that super-efficient solar cells collect the sun’s power in space, convert it to radio waves, and then squirt the energy down to Earth, where it is converted into usable power. The defense industry, which is championing the concept, wants to use the satellite-based tech to provide remote power for forward-operating bases that currently require difficult and sometimes dangerous-to-obtain, escorted fuel deliveries to power electricity generators.
