Good day,

Has there been any work to demonstrate the technology needed to send large amounts of energy through a comparable distance of atmosphere? Is that part just a given or has it already been demonstrated? For some reason it rings a bell but I can't remember if or where I heard of it being tried.

Anonymous, it was the photo from the japanese source article.

Qraal: I recognize that this is a long shot, which is why I mentioned small steps in the title. I think the low earth orbit approach seems like a better way to go. If Japan is going to make SPS then I think the direct to laser power transmission that they are working on is better

Messing about with antennae is all very well, but there's a long way to go to get to 1 GW. Smaller demosats might be a better way to test microwave power transfer.

Hi. The pic attached to your 'solar array' post has nothing to do with the subject. It is a traditional offset fed C band parabolic.
