Its running for 15 minutes and then must shut down for a long time to cool down. Thats exactly why those "science-fluencers" said its a dumb idea. This is far away from proving that its a viable idea.
_Radiative cooling_ is the only option because it's in vacuum. But you can transfer heat to the radiator either passively (using thermal conductivity), or actively (using coolant). The second option allows to effectively use larger radiators.
BTW, we seem to have Noisesphere instead of Noosphere.
