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.

- duckymcduckface 7y agoMy 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.
- TheSpiceIsLife 7y agoIsn’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?
