lol, that would not work on so many levels, mainly the physics that would wrap the elevator around the earth due to the earth's spin and moons orbital period being nothing alike

I can't think of any contradictory inventions right now

Except for the multimillion dollar investment of a pen that works in space, when a pencil is perfectly useable...
