will man harness the energy of the hurricane
will man fall to earth
will I invent anti-gravity plates

The cable itself has to extend past this (60,000 miles is a decent ball park) to allow a counterweight at the top. You can't take a space elevator to low Earth orbit, the physics doesn't work. Remarkably enough Wikipedia's article is, at least at time of writing, fairly good, see http://en.wikipedia.org/wiki/Space_elevator for more details.

how fast will the elevator climb?
