   How much energy can mirrors focus onto a solar panel before it begins to   
   melt?  2x?10x? 100x? It's an SSPS based question. Could large light-weight   
   mirrors and small solar arrays replace the traditional massive structures of   
   the NASA 1980s design study? This is something I haven't found in all my   
   googling.   
      
   Anyone here know? ;)
