I really canot understand why this is being discussed at such length. The
laws of thermodynamics state that heat energy (radiation is a form of
heat) flows from warm to cold and entropy increases, end of, surely?

I now realise that the problem is that we are talking at cross purposes.

No. You cannot see the problem. The problem for you is that cold radiation does not exist and you are the only person in this newsgroup and perhaps the scientific world, who thinks it does.

See the problem now?
