There is no reason to build this that big and we simply can't do it with the technology we have now or can expect to have in the next 38 years.
A tether to the ISS with an elevator though? I think if we truly wanted to we could have it in place in a couple years. Just need to get some one to pay for it and shooting up a rocket every now and then is cheaper and gets the job done.

i am by no means even close to knowing much about orbits or geosynchronous orbits so i wont go there all i know is that it has been proposed alot before and we just didnt have the tech to do it

its actually alot cheaper in the long run to put an elevator up and use it to haul stuff into space i dont remember the exact numbers but its something like $10,000 for every pound of crap that we send into space plus most of the weight of a launch is the fuel it takes to get it to space with something like this in place costs of going to space could theoretically be cut by a factor of a 1000

The question here is why do you hate progress?

I don't hate progress, I hate stupid ideas. It's far more economical and safe to fly to space than it is to take an elevator, especially one that could be destroyed by natural occurrences. All of the progress made in the X-Flight space races have proved that we can get aircraft into space without having to experience excessive G-forces or sit on top of ginormous rocket boosters.

But sure, go ahead, build it. But when the thing gets ripped out and sends 30 people hurtling out into space and we'll never be able to retrieve them, don't say I didn't tell ya so.

It costs multiple millions of dollars to haul a small amount of cargo into space. Those millions would become a much smaller number if there were a space elevator. A space elevator may not happen soon, but it will happen eventually, and it will be economical.

I understand your concerns, but you should probably have some faith that large teams of scientists with PhDs may know better than you.

Safe?

Sitting on top of close to a million gallons of liquid helium and liquid oxygen that is going to be mixed and combusted just below where you are sitting is considered safe in your book? Perhaps you don't know this, but an 18-gallon tank of gasoline is a small firecracker compared to an equivilant level of liquid oxygen. If that explodes, you're in for a ride that will hurtle you into the middle of next week. The ONLY thing that makes it safe is that there is a massive team of engineers sitting on the ground monitoring every tiny little occurrence throughout the entire mission. Have you ever considered that one microscopic crack in the fuel tank or one of the booster rockets could create a fireball so large that it would incinerate the entire rocket and shuttle in a matter of seconds? Not to mention the untold costs of each launch... and that's only if everything goes right. If something goes wrong, the costs go even further into the stratosphere.

As for the proposed space elevator, no fuel needed... at all. There is a strong chance that this would be a world endeavor. This means around the clock monitoring, security, and precautionary measures would be in place to keep any sort of issues from arising. After that, maintaining this elevator becomes the only real obstacle. If you haven't read about the tensile strength of carbon nanotubes, I suggest you do some research on it. They truly are a miracle of nature that could lead to some amazing creations in our near future. They're expensive right now because no one makes them. However, get some large scale production going, and they will become as cheap to produce as a plastic toy. At that point, the sky becomes the limit.

If you know of a better way to get people into space other than this, please let us know, because those massive rockets just aren't doing it for us. Astronauts are trained sometimes for years for a single mission, and then that's the end of it. If that's the pinnacle of human interactions outside of our tiny little marble in space, then our race is doomed.

The accomplishments of the those projects are extremely modest. They are barely touching the legal definitions of space, and pretty far from reaching orbital velocities, or anything of practical value. By the time the project nears completion, there will be an armada of support craft, free standing space stations, etc. there to catch any elevator passengers that go whizzing into space.

Why do we need this?

What is it thats 96,000 km up in space that we need an elevator to get to it?

if i go, i would want an elevator all to myself. i hate to be the person to admit they ripped a fat one during the trip, me being a very gassy person, and all..

We bring stuff into space all the time. Telescopes, satellites, space stations, space shuttles, etc. Those things all get into space through very expensive launches of rockets, if we had an elevator capable of hauling even a few tons, you could bring almost everything you would need into space using the elevator and save billions of dollars. Also, we would be able to bring stuff into space much more often. And getting back to Earth would be much safer.

I guess I don't see the reason it would need to be up that high for a geosync. That is one of the many reasons for the cables. They should hold it in place. Though I guess a geosync orbit might take some strain off of it, but still...that is a long way to build it. I think a 400km very strong cable system would be easier than a 96,000km cable system that would only be slightly less as massive.

The cost effectiveness of it could be debated in many ways. The cost to build something like this will be enormous. There is no telling how many launches can be done with normal rockets with that amount and it isn't like we have stuff to put in orbit every day. Plus there isn't any way to know what the operational cost of something like this would be. It might be more expensive than a rocket launch...but one thing is for sure. It would need repairs and re-running the cables would not be cheap...it's initial build cost would likely come back again every few years of operation.

It is a cool concept...but unless we can put something like this up and have it require little maintenance I don't know if it's practical. Though I suppose we would never develop a system like that without first trying one that is money pit. So I am certainly hoping to see it get off the ground...literally.
