I beg you pardon, im not arguing for the idea of a earth to moon microwave power link as viable. or sensible. I think it's beautifully insane, i have severe doubts about the actual practicality of such a thing, etc.

But thats the thing: now i want to do a mad max maser on a truck with maybe dozens of magnetrons if i could tow a generator...

It fits with my "Orbital Slingshot" project so well, too.
