   A space elevator is not possible in reality.  It is a running joke in   
   engineering land.   
      
   	calculate the mechanical loads.   
      
   	calculate the weight of copper cables, and the mechanical cables   
      
   	calculate the weight of the tower, and estimate the sizes of tower   
   sections to support the weight at different levels   
      
   	estimate the weight of the electric motor 150 HP   
      
     going to use a counterweight ?   
      
      
   just ballpark it,  assume 0.1 m/sec and 2000 # weight of cargo, and   
   100,000 foot high.
