   Wrong again.  you skipped over the part where you get ore from dirt, how   
   much energy is that ?   
      
   AND you skipped over the fact that the steel making facility is built   
   and operated in a vacuum, add in those costs in terms of energy, and   
   cleaning the air inside from fumes, that cost.   
      
   your responces to posts here are simplistic, from 100,000 feet high with   
   no reality, a salesman from Musk.
