I truly hate to add to what may be perceived as a growing dog pile here, and I only speak in hopes of clarifying what I believe is the underlying question by the OP.

To wit: in other threads at other times Warrior has indicated that he either does not believe in radiative heat transfer, or that he believes it is an effect of too small an order to be important in the thermal design of spacecraft.

I will not put words in his mouth. What I would like to respectfully suggest, however, is that we back off and allow him to clarify the point in his original post that he wishes to draw our attention to. If it is, as I believe, what I have indicated above, then detailed discussion of thermal design is basically a sideline to the subject of this thread.
