Here we have the necessary 'I am smarter than Elon' post.
I wonder if Jan realizes that there are 11,184 Starlink satellites in space, 'cooling' right now through their radiative structures.
Not the same heat dissipation requirements as the Starmind sats, but I think it's reasonable to say Elon knows a thing or two about satellite thermal management.
Jan got his impression count, though I am not sure that was his objective.
