In the last few years several projects have been proposed to collect solar power in orbit and then transmit it to Earth.
- Two of the possible designs are: a) generate power using solar cells in space and transmit the energy to Earth as microwaves, and b) reflect sunlight to boost power generation for Earth-based solar panels.
- Several experiments have been run so far to examine the viability of the long-distance power transmission.
- However, up to my knowledge, direct power transmission from space to ground hasn't been tested yet.
- This question will resolve positively as soon as it is first demonstrated.
- To distinguish power transmission from a radio or laser communication, the receiver has to have efficiency >0, i.e. it should produce more power than it uses for the reception.
