The conversion efficiency would probably only be about 25% efficient end to end. The solar flux at the earths orbit is approximately 1600 Watts/meter-squared. You’d need about one square mile of orbiting collectors per gigawatt delivered power. The power could safely be focused on area the size of a football field, the collecting antenna. Spreading the receiving antennas would be unnecessary and probably unwise. You need to spread the transmitters to effect a small ground spot and to keep them “decorrelated” in the event of the failure of any one satellite.
I just used New England as the foot print size of any one transmitter as an example.
I’m not at all convinced it would be economically feasible.
You obviously know what you are talking about
