   Wrong.  Of course there is.  Just take them outside, heat them, and   
   take them back inside before they cool.

   We already established that your "rocks and sand in a vacuum" is   
   false.  The fact that you still repeat it says you're stupid.

   Water, oxygen, various other gases, including methane for rocket fuel.   
   As a colony gets bigger it will start to pay to locally produce   
   metals.   
      
   Try and keep up.
