This is an exciting idea and one that has been around for a while.
Instead of building massive rockets to blast people into space,
have a permanent space elevator to take people to space.
The idea is to have a very large weight in space on the end of a
VERY strong cable attached to earth, and have an elevator
run up & down the cable.
The centrifugal force of the weight spinning around is supposed to counter
the force of gravity.
With the advent of new materials such as carbon nano-tubes, a cable strong enough
is now feasible. Given enough money it seems that the space elevator could
be built. Nasa has even sponsored research into the concept.
