my air conditioner is rejecting 3000 watts to the outdoors right now, even though my bedroom is the same temperature as the nighttime outdoors. doing that with radiative cooling would require 8 square meters of emitter area at 400 watts per square meter and a clear, low-humidity sky (not necessarily night, but in the daytime, you additionally have to keep the sun off the panels). my air conditioner's condenser is significantly less than 1 square meter as seen from the sky and also works when it's cloudy or humid outside

basically forced-air convection heat transfer is a motherfucking miracle, and vapor-compression refrigeration even more so

I am disappointed you could not come up with a more concrete term for an improvement over a 'motherfucking miracle'. :)

But, yes, heat pumps are magic shite.
