Umm, not only do you have to fuel the power sats but you have to fuel the

BTW, it is totally unnecessary for the sats to be in phase if you are using
a laser sail concept. You are simply delivering a concentrated replacement
for sunlight, it doesn't even have to be monochromatic. I'm not familiar
enough with your microwave concept to know if you NEED coherent microwave
energy at the the receiving end.

in a Vague and Undetermined State.
