Comments on Japanese Company To Build Space Elevator?
Establish an elevator system linking Earth to space! (Read
the complete story)
| "A question that nage at me is what will keep the weight of the cable itself from pulling the counterweight down into the atmosphere and crashing?" (Joey1058 2/24/2012 1:05:39 PM) |
| "A counter weight has to project away from the Geo-stationary point. Objects released from the counter-weight will be at escape velocity." (Peter Jacobs 2/24/2012 4:39:55 PM) |
| "Joey, you're right, the weight of the cable is a big problem; that's why Arthur C. Clarke spent a lot of time thinking about what to use as a material. Take a look at this discussion of a (fictional) one-dimensional diamond (carbon) crystal. This sounds very close to carbon nanotubes discovered about twenty years later." (Bill Christensen 2/24/2012 6:08:12 PM) |
| "Another example of a science-fictional material that anticipated modern developments and coud be used for space elevator fiber is the Sinclair molecule chain from Larry Niven's 1968 novel A Gift From Earth. See also this real-life example of an amazingly light yet strong nanotube stretched between two tungsten needles that acts like a wire cheese slicer." (Bill Christensen 2/24/2012 6:10:50 PM) |
