Can scientists make a space elevator?

(CNN) -- It sounds like science fiction. And it was.
Now, 30 years after "2001" author Arthur C. Clarke wrote about an elevator that rises into outer space, serious research is happening all over the world in an effort to make the far-fetched-sounding idea a reality.
The benefits of a fully realized elevator would make carrying people and goods into space cheaper, easier and safer than with rocket launches, proponents say, opening up a host of possibilities.
Restaurants and hotels for space tourists. Wind turbines that provide energy by spinning 24 hours a day. A cheaper, easier and more environmentally friendly way to launch rockets.
Scientists envision all of the above -- possibly within our lifetimes.
"Space elevator-related research is valid, but there are hurdles to overcome," said David Smitherman, a space architect at NASA's George C. Marshall Space Flight Center.

First, I think the question should not be "Can scientists make a space elevator?", but "Should scientists make a space elevator?"

Yes. - Aside from the design considerations - such a device allows a cheap access and, because of necessary design characteristics, large scale solar power can be fed down without tremendous adverse environmental problems accruing.
We could have several such elevator/power stations/space and craft stations.
There are many financial aspects that would make profound and on-going wealth for the world as a whole.

I dreampt up a space elevator in '82, from never hearing of the idea. There are physics aspects that I conceived and answered that remain of un-thought of, by all these "designers", still.
The mass of all elevators so far expounded would pull their structures apart. Utterly.But I know the way... :-}

The main thing I worry about is how ugly that thing would be. A seemingly endless tube in the sky. Who would want that in their view?
Plus there's a ridiculously large amount of manmade refuse stuck in orbit around this planet. It seems like it would pose a bit of a threat.
And what if it fell over? Haha.
Okay. It's exciting. - 2 years ago

"A merely clever man could never have thought of it" lol... I thought about this idea when I was 14, now that i'm 33, I don't see this happening at all. We might support it, but the government and it's old farts some of you keep electing, won't do it because it's not profitable enough.
Our government is made up of millionaires, they would only do this if they can make money out of it.

Except that would be physically impossible. Sure, we could have the capacity to build one. But, mind you, the planet is rotating and there are asteroids and comets passing near our planet all the time. Even if we DID build one, it will most likely be destroyed within months.

The rotation of the earth would have no effect on such an elevator since it would be attached to a geostationary satellite.

I'm not saying the rotation is a problem. My biggest problem with this are the debris in space that may impact the structure. It's a great idea nonetheless.

Would it be futile to create a space elevator? How will it work and will it rotate with the earth?
However, I do love the space hotel idea. I wish I was filthy rich to stay there just for 1 day. I don't even like to fly and I still want to experience space.

It could only be linked to a geostationary satellite, so yes, it would "rotate" with the earth, i.e. remain in the same spot above earth.

what we need is skrith ( ring world engineers).
where do we put it? the equator has a bulge due to the spin and is shorter but the spin is at 1000mph.. the poles rotate once a day at almost 0 speed but the problems there are legion. i think maybe jim kirk's home town in iowa.
our tower of babble might be made of diamond, at 22,000 miles that's a lot of carbon. 90% of diamonds are artificial and are industrial not gem quality. actually most diamonds mined are used industrially. a diamond tower could transmit energy and even cool the earth as diamond has the greatest heat transfer( that's why their called ice, they are always cold to the touch). - 2 years ago

I'm a huge fan of this idea because its very theoretically possible. Geostationary orbit is about 222,236 miles above sea level so it would be an incredible engineering accomplishment, but it would save a ton of money since most of the fuel in our rockets is just to get through the atmosphere.

I have a feeling that it would fail catastrophically unless the "anchor" in geostationary orbit was several hundred times the mass of the payload it was carrying. For instance, if we "tied" the moon to a cable.
Otherwise, the force on the cable would just pull the anchor towards earth rather than the pull the payload up. Even still the anchor in the "sky" would be pulled into a tighter and tighter orbit, and some sort of force opposite to the payload would still be required to move the payload away from the earth's surface as it overcomes gravity.

Arthur C Clarke had to have been an alien. His books accurately predicted iPods, external hard drives, Skype, flash memory, search engines like Google, email, and more, back when computers were the size of buildings and could barely compute 2+2.
He also holds credit for inventing the communications satellite. Brilliant man.

A space elevator will be seen by 2030. Unless of course we kill ourselves off with pollution and/or disease.
Self replicating carbon nano-tubes were looked at a few years ago. Don't know if anyone is still working on it from that direction.
Wonder if they'll let an old lady like me up there when it's built? - 2 years ago

Nano-tech and buckyballs and buckytubes MIGHT do it, once we already have a manufacturing colony on the moon or asteroid belt, but not any time even remotely soon. With fusion plants to provide energy on a colony,...really really efficient batteries and conductive materials,..... Basically its hard to get a handle on how advances in multiple fields will reinforce potential.

I don't know about you guys, but wouldn't gravity combined with both the speed of the Earth's rotation and the speed in which it orbits the sun kinda, I dunno, rip the whole thing apart?
This seems like a pretty impractical way of getting to space, considering that one guy even created a space ship that flies using - wait for it...

That's what they said about the lunar landing. It might seem that things like this are totally impossible, but remember: we as a species fricking crazy. That's how things like this get done.
When we were still animals, all the other animals laughed at how stupid those apes were playing with fire, eating everything in sight just to see if it was edible, and jumping off cliffs while holding big leaves. Now those apes are building hundred meter windmills and trying to throw ropes into space.
