Question....if satellite TV that already beams microwaves to earth has issues during cloud cover...how will this be any better? Sure the power may blast through but the efficiency of that will drop depending on the weather.

Well, I guess progress is progress. If you don't try, you won't know. You keep going until you get it.

However here is an idea, what about using this for, i don't know, powering habitats etc on the Moon?

"Microwave" is a big range, from 1 to 1000 GHz. Satellite TV is in the ~10-20 GHz range, but I believe there are frequencies where clouds and rain are more transparent.

Edit: https://en.wikipedia.org/wiki/Microwave_transmission#/media/...

So I guess the goal would be to pick one of the high points on that graph that also wouldn't wreck havoc with telecommunications.
