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.

Can you elaborate on that ?

#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.

How old is this vid?
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.

According to my knowledge: the moon rotates/moves around the earth !!

I'll have to say: Never. Never in my life time and any members on Snotr today.
