Oh, right, I understand now, thanks.

  I love radiative cooling. When you first realise what the hell is going on, it is one of those 'aha' moments of real deeper appreciation of a subject.

    My favorite demo is an electric stoves, turn it on and stare at it from a point along the plane that it's on and you start to marvel at how much heat can be transferred by radiation.

      Isn’t that convection? The air coming in to contact with the hot surface rapidly heats and rises and cooler air rushed in to replace it. I thought that’s what we saw as per your instructions? I thought air (mostly nitrogen and oxygen) is mostly transparent to infrared radiation?
