So we have all the technology to build a working space elevator.
Why do you think no ones built one yet? Is it simply because no believes its of any value? |

I still think we have a ways to go with the carbon nanotube technology until we are running lines to the L points.

Contrary to what you've seen on Star Trek, there's really nothing all that interesting beyond the atmosphere that we could get to within a human's lifespan.

View Quote If someone takes a picture of it with a flash the cables will fail. That, and the anchor has to be in geosynchronous orbit, which means any non-geosynchronous satellite is going to have to dodge the cables. |

There's not so much going on @ geosynchronous orbit that can't be done w/ conventional chemical rockets far cheaper than a space elevator. And then you've got to pay Space Elevator Operator Union wages. |

Bullshit. Building a simple wall on our border with Mexico is too complex and costs too much. There is no way we can build a space elevator. .....at least with fucking democrats in charge. |

Space elevator is the stupidest way to get into space I have ever seen. We do not have material yet to make it or any way to erect it. A completed elevator would cross through every orbit possible to an altitude a bit above geosync creating a collision hazard for all those satellites below the counter weight at the top. Its 22000 mile to geosyne where you get off, at 1000mph it takes a day to get there. What are you using to propel the elevator car up the ribbon over that great distance. Retarded idea!

View Quote I don't think the technology is there yet, and how are you going to protect it? Missles, guns, suicide planes, and lasers will be some of the threats. |

The minute you put the cable under any kind of sizable load it will pull the orbital station out of orbit and it'll all come crashing down.
And that's bad M'kay... |

Elevator isn't really what you need , more like a funicular. The cars coming down loaded with ore from mining the asteroids would pull the cars up the cable to the orbital station. Once it was built and running the power for its operation would basically be free.

Getting close, but we have yet to fab a carbon nanotube or graphene belt or cable. But we are close. I would SWAG that we will be able to build a 1 km proof of concept device within the next 20~40 years, possibly within a decade.
Although admittedly it's a big step going from 1 km to 35,786 km. Lots of issues to consider. Lots... cable tension, electric and air current effects, Van Allen radiation, ionospheric free oxygen... space junk... ETA: there was a Shuttle experiment several years ago that involved lowering a tether a few km, and it ran into all sorts of problems. It might have been attempting to charge the cable to demonstrate altitude control or power generation, but what ever it was, they fried the tether. ETA2: Atmospheric free oxygen -- read up on the Long Duration Exposure Facility experiment. Wow. |

Best sci-fi description of working elevators I've read was in Kim Stanley Robinson's "Red Mars".

No one knows how to build a space elevator, despite Pop Sci articles.
It's one thing to make a couple of sketches, and another to maybe do a free body analysis of the basic tension load in a string, and it's four or five orders more complicated to do a first order analysis and design to solve the problem, a problem that isn't defined as in "what's it going to do to make money?".

Why climb mount everest for a cup of ice when you live on a glacier?
|

Fuck the needle, gas chamber, and electric chair. Once they build a space elevator, you can just ride em up there, open the door, and space the motherfuckers.
|
|
No, we don't.
Current industrially produced carbon nanotubes are just over the theoretical minimum strength needed to build a space elevator from Earth. This leaves no safety margin. Which means it will not work. Something 20-100% stronger may be required. Graphene ribbons are promising. |

All the humans to farm are here... Let them start wandering off and who knows what they might do. Can't have large populations moving to a new territory and potentially declaring independence... just look at how that turned out last time.

Not enough strands to make the cables right now. A slow-process in making them.
|
|
We don't really.. We don't have way to build a single nanotube cable 22,000 miles long that could support its own weight let alone all the added forces..
|

Because the costs would be full retard, it would fuck with the airways, and serve no purpose.

space travel will remain rather stagnant until there is profitable money to be made there.
Our technology needs to be up to task as well. Good news is we are still in our infancy of space travel. The first ship builders didnt cross the oceans 50 years after building the first ship either. A lot has to be learned and new techniques, and technologies developed. |

High altitude lightning, sprites, etc. will probably mess with any graphene ribbon too - as well as the UFOs and other aerial critters.

Space elevator is the stupidest way to get into space I have ever seen. We do not have material yet to make it or any way to erect it. You don't erect it. You drop it in... Derect it? That is a complicated task though. A completed elevator would cross through every orbit possible to an altitude a bit above geosync creating a collision hazard for all those satellites below the counter weight at the top. Uh, no, that isn't how it works. Orbits are three dimensional. An orbit at a lower orbit does not inherently conflict with an elevator. Its 22000 mile to geosyne where you get off, at 1000mph it takes a day to get there. Is a week to orbit such an unacceptable idea? Especially if multiple cars can be ascending at once. What are you using to propel the elevator car up the ribbon over that great distance. Retarded idea! Electrical power from the ribbon, just like a streetcar or subway. |

No reason to go to space right now until we develop better energy sources. Whether better batteries or a sort of non-chemical rocket for propulsion. Which then we would need faster speeds and faster communication. Near light speed stuff is a long way off.
Maglev launches are more promising them a space elevator currently. Especially for non-human cargo. This would be good for getting back to the moon or going to mars. Which could open up a bit more. |

i hears someone once say that relativity prohibited it. Something about how the speed of time being different at teh surface and in orbit b/c the thing is orbit is going 15k+MPH. It was a scientits that said it but it was just mentioned in passing in a radio interview. I have NO idea if it makes snese or not.

Because Muslims would blow it up?
Because the feds won't allow it to be built by private ventures because the fed would want to control it, and won't spend taxpayer money on it because the free shit army needs to be bribed to not riot? |

I think the moon, Mars and the asteroid belt would do for starters. Plenty of territory to rape out there. Don't need a Space Elevator for that when a cheap rocket powered tug will do, hear me out. If we were to find an asteroid in the vicinity of Earth or one approaching, I suppose it would be cheaper to send a traditional ship out there to tether it and bring it to a Near Earth Orbit for mining. Do we need an elevator when we can just drop the mined ore into orbit? Sure getting up there will be more difficult, but the cost of a Space Elevator will far and beyond eclipse the cost of anything we have ever built in Human history. One good metal rich asteroid would change the economy of the world. tldr version: I think it would be cheaper to send a fleet of tugs out, tether and asteroid, bring it closer, set up a mining facility and drop the booty back to Earth. |
