>Also, to be clear, we're talking about Dyson _Swarms_. This is the original design idea that was called Dyson Spheres but that name is often not used because people mistakenly think we're talking about a rigid shell that encompasses a star. That is not and never was the intent. It's also impossible for many reasons.

Thank-you for clearing this up for me. I made a post after you, but you addressed the issues that I discarded. I now know more then I did. Thanks!
