A disturbance travels up a space elevator cable in a simulation, with the horizontal scale of the wave exaggerated for clarity (Animation: David Lang, Software: Paul Snow)

  • oh true. yeah you're right. there must exist an optimal distance from earth's surface so that its rotation will keep the elevator's carbon ribbon in tension. i think they are calculating for 22,000 miles.... not sure what that is in kilometers. after america is done making the space elevator, they should work on converting to the metric system.

  • Or a giant bullwhip.

  • *cough* Graphene *cough*

  • if earth is dragging the anchor, why not make the anchor a huge kite instead of trying to reach 22,000 or w/e miles to space? we could slowly accelerate up to a speed that would escape earths gravity without needing anymore ribbon to ride. it shouldn't be a casual elevator, it should be a runway.

  • when its in tension it should be stronger than steel. i suppose nothing can screw with it.

  • @Nexstarcrazyness

    They've already sorted this, the bigger issue is space junk, orbiting trash and satellites. But then again they more or less have solutions for those too.

  • it looks like the space elevator is goin to collaspe.

  • A bird innocently flying by would just smack right into it causing this shockwave.

    Place it in a part of the world void of flying animals, weather and wind (not bloody likely).

    This elevator better not be like flying a kite!

  • But how is the strength of the force that holds the nanotubes together, is it a weak point?

  • *apparently*

  • apperently

  • absurd idea isnt it? i thought it would be clear it was a joke, apparently not.
