   This actually isn't the reason it won't work. It will ATTEMPT to radiate in   
   all directions, but it won't be able to radiate effectively through the mass   
   of the material around it. That said, it WILL reduce efficiency considerably.   
   You ARE correct that it won't work, because of your second reason...   
      
   >   Second, you now have all points on the radiating surface "looking at"   
   other points on the radiating surface reducing their ability to lose heat.   
   Heat emitted by any point that impacts those other points is reabsorbed and   
   has to be re-emitted, raising    
   the temperature of the whole emitting surface. While that helps radiativity   
   because heat flows better from a hotter radiator to cold space, it becomes a   
   choke point for heat flow.   
      
   Quite correct. I was thinking about that almost as soon as I sent the message.   
   I was not considering the opposite side, which will now be angling in the   
   direction of the proximal lip.   
   A flat surface will be best, angled away from suspected platform positions.   
   While there WILL be emissions in all available directions, on edge emissions   
   will be quite weak.   
      
      
      
   On a completely unrelated note: I would like to remind everyone that my   
   schedule is quite erratic at the moment. I don't know when I will be able to   
   find time to respond.    
   I still have more responses I would like to make. I will get back to them when   
   I can. Don't be surprised if several days or more pass between responses.
