Parabolic Steam Generators versus PV

I probably didn't explain very well what I mean. SPBS is in GSO at an essentially constant place above the surface and fine steering is done to keep it at an optimum position for the rectenna.

If you beam from the moon, I assume from one of the poles, you aim it toward the Earth. Then at some point you have have to reflect it to the surface, more than once when you reflect to the opposite side of the Earth from where the moon is. But essentially the Earth is rotating every 24 hours under the moon so you have to constantly adjust the distance that you are 'shooting' at the reflectors.

I know the microwaves and reflected sunlight are variable based on distance so if lasers are used and are less sensitive that makes more sense to me.
