   There were a lot of YouTube science-fluencers talking about how dumb this idea was. Google themselves called it a Moonshot (har har).

   Curious to see if the experiment changes our understanding of space radiators at a certain scale for non-space exploration purposes.

      It is 700w of heat radiating by 1m2 at 70C ( ie one GPU can sit on such a radiator) What is not to work ok here?

         No air. No convection, only radiation.

            That is what I said.

               What you said was just a statement, not something with evidence or reasoning for why it should work. How large of an area is required to dissipate that much heat in a vacuum at a constant rate?

                  that is exactly what i said.

                  >something with evidence

                  middle-school physics, basic knowledge, at least if you decided to participate in such a discussion.

                     I read your statement as just stating what they had done (or planned to do), not that you had calculated that as the correct/sufficient amount. If you read it that way it sounds like 'they provided X amount, why shouldn't that work?' which reads like a statement without evidence of why it would work.

                     Sorry for misinterpreting your statement.
