   If the elevator continues to stretch out way beyond the balance point,   
   at a certain length if we cut the anchors on Earth, it would float out   
   away from Earth, wouldn't it? If the center of mass is at escape   
   velocity for it's orbit altitude, the whole thing will float away.   
      
   So we can use that capability by just tossing off mass at a much greater   
   altitude (thereby slowing the Earth's rotation) and using that to lift   
   the elevator. via a long cable loop. We could toss off bags of water, or   
   something else that would disperse and cause no harm.
