The cooling problem is more tractable than commonly assumed
I have been extremely skeptical that this is the case, and there is an error in your analysis (you need the more expensive AZW/LA-II paint rather than the cheaper AZ-93), but the 45°C operating temperature announcement of Jun 21, 2026 [1], makes all this possible if still unproven in practice, even if you still need 1.2 square kilometers of radiator per GW. Thank you for researching this information!
