[Rhodes22-list] Going green

[Ronald Lipton]

>From Wikipedia:

For example, the complete Space Shuttle system has:

  a.. weight at liftoff: 4,500,000 lb (2,040,000 kg)
  b.. weight at end of mission: 230,000 lb (104,000 kg), and
  c.. maximum cargo to orbit: 63,500 lb (28,800 kg)
So it is burning 4,270,000 pounds of fuel to put 63,000 pounds into
a low earth orbit.  Not real efficient.  I sure one can do better with
a one-way rocket but this real far from practical.
