this is a simple reason why the space elevator will not work.
there is too much reletive movement between the earth and the
orbit for such a task to take place. if someone has an explanation
please explain

The geosats I've worked with (only a couple) have always danced
around in
an
odd figure 8 pattern over the equator. It's only fractions of a
degree,
but
wouldn't this make for quite a problem on the ground?


Unless the orbit is perfect, the elevator will have to flex, and
that's OK.
Tall buildings are designed for it, bridges are designed for it, and
the elevator would be designed for it.


I wasn't too worried about flex, it's the fact that the end being
lowered to the ground would be moving over a fairly large area and
might be hard to grab hold of. I don't know--just a thought.

Most space elevators designs are anchored at the Earth end. They only have
to be grabbed once. The "figure 8" pattern you describe has a period of a
day - very slow movement - and it's caused by orbit perturbations that
build up over time. So as long as the elevator is deployed fairly
expediently, the magnitude of the pattern should not be too wide.
