My main concern is the ramification of a possible accident.

Guest That's one thing you needn't worry about, we will not see a cosmic beanstalk in our lifetime.

If the technology has arrived, which it has not, who by chance would pay for it?
Can you imagine the cost overruns if we let NASA build it, yikes.

Certainly not the USA as we're already 9.4 trillion dollars in debt.

If it operates like the elevator where I work, it'll take years to get from the ground to space. Assuming some a-hole hasn't pushed the buttons for every stop.

Hmm...stops on a space elevator...sounds like a skydiver's dream.

Space elevators must exist! They actually have their own website. www.spaceelevator.com

So, if the Earth is Mother Earth, female, according to the Gaia theory, would the space elevator be the birth canal, or is Earth more of a Divine-sort of female??

Cord? Placenta?

My main concern is the electric potential difference that exists between the ground and the upper ionosphere. It's tens of thousands of volt, people! If not more. All experiments performed to date with tethers lowered from a space vehicle have ended up with the tether melting down due to a sudden catastrophic dielectric breakdown. I hope that space elevator is impossible. Because if it is possible, then we will rue the day it is constructed. You want to short the auroral circuit? You want to bring down the voltage that ultimately powers all lightnings on Earth? You have no idea what you're asking for.

P.S. And don't get me started on things like Dyson spheres. Trying to stop the solar wind? Yeah, right.

Then think of it as transportation and a power source.

Those physicists I know who aren't too square to have heard about the concept do seem mostly to think it's probably not possible, materials-wise.

Also, if it were possible, it would be the ultimate terrorist incident waiting to happen.

Trust me, if it falls, that would be a relief, compared to what would happen if it shorts the auroral circuit. Of the two evils, I would rather choose the simple mechanical crash.

There is another possibility that may be worse than a crash or a short circuit - being stuck between floors.

It does seem unlikely that the technological and engineering difficulties can be overcome--but, of course, at one time they would have said the same thing about the Golden Gate Bridge, the Panama Canal, the Chunnel, or 100-story-high skyscrapers.

Or the Transatlantic tunnel, Hurrah!
