Is there any reason why (in theory) we can't release heat to space in some other way? I can think of many (imaginary) ways of releasing space, for example shooting superheated materials to space, maybe some planet-scale laser-powered heat pump or radiator [1]. I realise such solutions (in general, please don't focus on my examples) are not currently possible and very far from what we can do, but there's no physical reasons we can't invent them during the next 300 years, right?
