that good ol' space elevator

slight breezes for the lose :(

lol

Wouldn't the wobbling of the earth and its slight irregular shape (compared to the shape of the orbit) pretty much put too much stress on this even for carbon nanotubes?

Besides which, i think the psychological stresses of a 15 hour elevator ride (complete with cheesy music and the other crew members farting) would be WAY too much for the human mind :D

not to mention the weight of the aparatus, would it not take quite a bit of force to hold it in orbit? forgive me if I'm wrong, I'm no expert with this.

*cough*. Once an object is in orbit...you know, zero gravity....I don't think it matters how much it weighs. It's in zero gravity.

Right?

yeah, once in orbit, it wouldn't need any more force, there's an equilibrium between Earth's gravity and the pull from space, both equalling 0. However, once in orbit, the satellite needs a miniscule amount of force to be knocked out of its orbit or pushed into a new one, on a trajectory towards (to use the example in the article) Saturn. It would be very cost efficient, as long as the elevetor has a decent operating cost and is quick. If not, this would be totally awful. It would break easily too, I'm fairly sure. Those stupid aeroplanes... what with their spelling errors and all...

Overall, I'm guessing the elevator wouldn't be as efficient as the shuttles, unless we truly embark on the space era where all people go to space.

It wouldn't be efficient unless we made a bunch of them around the equator and made a ring connecting them. Can anyone say "Kane Band"?

heh, not in this lifetime, either way, good point with the zero gravity, however what about the cable's weight, since it will still be in earth's gravitational influence throughout most of its structure, but eh, I'm no physicist

if im correct the carbon nanotubes that were spoken of are way stronger than steel and hundreds of times lighter as well. im not sure on the exact stats for carbon nanotubes vs. steel
Mar 23, 2005 epadafunk link
they are about 20 times stronger than steel when mass is taken into consideration.

it is possible that they can be made much stronger, up to 100 times as strong as steel

PS is it really impossible to post this stuff on the elevator forum?
