> there might be three gathering-arrays, 120 degrees apart. Not sure why we would want to limit it to 3 arrays. I think we're more apt to see far more satellites, each no larger than Manhattan, than what you describe. But I do think you're right in figuring that the only real ultimate limits to growth are SPS shadowing other SPS. I'm certainly not expert enough to derive more-realistic models and end results, but even assuming your 60,000 Terawatts is in the ballpark, I'd say that's an admirably-distant limit to growth. I think every other potential source of power would run into technical absurdities before that. A lot of your questions indicate that you probably need to better acquaint yourself with the SBSP concept before confidently asserting that nuclear is clearly superior.
