   How much energy can mirros focus onto a solar panel before it begins to   
   melt? 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? ;)
