wind, weather, birds, all things considered there are so many fail points, but I am still optimistic this would work some day. Something flash to mind is, in the movie Star trek chronicle 2009, where Nero dropped that flame torch down on planet volcan and earth, that method would apply; instead of building a way UP, you do it top down. Have a space craft stay top orbit to hold the thing, it could become an elevator stair way to space. Gravity and weight and build materials ? leave that to crazy scientists

I'm somewhat disappointed that they didn't bother to mention the #1 problem with building a space elevator.

Extending a conductive material through each of the "osphere's" (atmo, strato, etc) would cause each and every one of our protective layers to electrically ground out and either result in:

a) eliminating the production of lightning world wide.

b) almost instantaneousnessly vaporize the "cable" with the tremendous amount of current/amps passing through the cable, causing the entire elevator to fail.

wow, im like super excited. if i could do it all over again id go be a scientist.

'Extending a conductive material through each of the "osphere's" (atmo, strato, etc) would cause each and every one of our protective layers to electrically ground out and either result in:

Can you elaborate on that ?

If this can be done within the realm of physics it will happen. With the brilliant minds we have in the world today it more then likely will happen. First the physics then the economics. :) Fantastic idea!! :)

Space Elevator idea is completely bogus. Alternative propulsion systems is only right way to get into space. Anti-gravity is very real. Just not quite in our reach yet.

#2 Doesn't sound right to me.

Lightning production won't be eliminated... Sure this structure would be a prime target for local lightning but this won't really have any effect as long as it's grounded. What do you think happens when lightning strikes skyscrapers?

And as mentioned in the video, the idea is to power the lift by lasers beamed from the ground, not by electricity via carbon nanotubes (it's just for construction).

Anyway, everything in this video is just theories, when we finally build this thing I wouldn't be surprised if it turns out completely different. Just hoping it happens in my lifetime. :'(

why cant power be transferred thought the cable like light rails and subways?

#1 its probably easy to guard cable from birds and what not since you only have to shield it for a few thousand feet. bird dont fly that high.

anyone watch gundam seed? they did this in the movie. mainly to connect solar panels from outer space. solar panels is more efficent in outer space cuz theres no atmosphere to get in the way.

Yes because we all know a jojo string *never* snaps. I went through a gazillion jojos when i where a kid. The problem was that the string near the center would always wear out due to excessive use.

Not saying the same would apply to this theory. Was just an odd way of explaining it, for me, and my experiences with jojos!

'The Fountains of Paradise' by Arthur C.Clarke. Read it.You'll see the idea is not that stupid.

The only thing stopping the production of the space elevator is the cost involved.
The technology has existed long enough for me to have done a study on it 6 years ago in Uni.
You can actually escape the gravitational pull of mars using a series of tethers(the proper name for the ribbon) on the planet and both moons.

i guess they toss out the battery idea just because of the seer power it needs to lift everything up.

im up for using the nanotubes as a way to deliver power to the motors since they said its a really good conductor.

if you could harness the energy into batteries you would be a multi billionaire
