Surely the coat makes you feel warmer by preventing heat loss by (mostly) convection? Your body core temperature is not warmer than it was before you put the coat on, you just feel warmer. I cannot find any reference to cooler radiation actually being absorbed by a warmer surface *for net energy gain* as that would appear to invalidate the @nd Law of Thermodynamics. Do you have such a reference? Thanks for replying.
