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.
