Patented 'space elevator' may put astronauts into orbit

[QUOTE=HybridTheroy;48492869]yeah at 35768 fucking km (seriously you're not teaching anything here, especially since it's already been brought up in this thread) that's not a space elevator that's just a large ass cable dangling from earth.[/QUOTE]
How about you do an ounce of research before acting like you know everything. I'm not teaching anything only because you refuse to learn.
Also an actual space elevator is technically in space and extends down to Earth; it doesn't start at Earth and go into space (it is under tension - pulled away from Earth - not compression - pulled towards Earth).

This thread is so hostile
Even idealized theoretical-quality carbon nanotubes aren't a miracle enough material to build a space elevator.
[URL="http://io9.com/5984371/why-well-probably-never-build-a-space-elevator"]Here's[/URL] a good write up of why it's damn difficult to build one.
iirc kevlar might be good enough for an elevator on the moon or mars. Though the moon's slow rotation provides other issues. Anyways on either planet if you made the elevator long enough you could ride the elevator up, let go, and then be on an escape trajectory. Be a nice boost to get cargo back to Earth.
[QUOTE=HybridTheroy;48493113]A cable that dangles around earth and eventually reaches orbit and at the same time contain vehicles that would bring you to the end would be pretty redundant let alone impossible.
The best logical choice is a plan like the one in OP, pretty much an airport on top of a giant tower.

Welcome to fucking language buddy, jesus christ.[/QUOTE]
Except the plan in the OP is fucking useless because all it does is get you a bit closer to space without providing any speed boost whatsoever. You still need a massive delta-v to get to orbital speed, and raising the rocket 20 km up isn't going to help anything.
20km up is nothing at all. You still have another 80km to go before you're even considered to be in space. The most I can see this structure being used for (this is a stretch too) is for a hugely elevated launch platform so you can ignore the first 20km of atmosphere.

gj not reading even the OP lol
[QUOTE=thrawn2787;48486071]I'm sure the inventor knows. But whoever is marketing this as a "space elevator" is kind of a twat.
If you jumped off the top of a space elevator you'd be in orbit.
If you jumped off this thing you'd fall to your death.

For actual space elevators it depends on where it breaks. It could fall and wrap around the earth a few times or it could go flying out into space.[/QUOTE]
you would be dead before hitting the ground, due to the thinner atmosphere and colder temperatures, assuming you are not an idiot and keep your space suit on.
[QUOTE=sltungle;48492410]Presumably you'd be able to get a small enough spaceplane up in a similar manner to the people (i.e. by hoisting it up there).[/QUOTE]
Ya but the issue is winds up there and lack of oxygen would make working on a space plane so high up all but impossible

Depends, currently its been shown you can dive from the edge of space and land just fine, as for re-entering from orbit, I cant exactly do the math but its going to be a lot more violent because you have to slow down much faster, but landing should be fine if you can survive reentry
