  • only one thing wrong with that video - the nature of centrifugal force means that the only viable place to put a space elevator has to be the equator - I suppose that means a bit of good old fashioned smash and grab from the global powers.

  • if this can be done then next should be a pipe to pump exess water from rising oceans.

  • great video, really educated the generation who are most likely to build an space elevator

  • wait this thing is just sticking out of earth right? I would feel sorry if an asteroid hit it or something.

  • @dbznerffan212 mobile seafaring platforms are designed to counter just that.

  • Ionosphere + charge, Earth - charge . Tesla knew this , lightning proves this. Has this been thought through ?

  • this stuff is awerson

  • i can see so clearly now

  • OH MY GOD THEY HAVE TO MAKE THIS... if i had a lot of money i would donate it all to people to make this

  • @Pacmanghost really? i wont.

    i will make my own. ha ha GO USA! and me

  • What a bullshit ! Technically impossible to build a space elevator !

  • @Corvard LOL so was a powered heavier then aircraft, a rocket to the moon, and trying to fly faster then the speed of sound. The impossible just takes a little longer.

  • Going Up: The Space Elevator

  • Cmon you guys, wouldn't it be cooler to bailout GM or some investment banks?

  • @skyelevator Will they give me a cheap ride to space if I do bail them out? I think not! ;)

  • OK, all you Chubby Chasers, your gonna have to dump that FAT 200lb girlfriend because it will cost you $40,000 just to get her up the elevator. 1 more benefit of having a girlfriend who weights less :)

  • Wooh! Great video!

    Space solar power doesn't need a space elevator if built from asteroidal or lunar materials. And it doesn't even need those if energy prices get high enough!

  • I understand the cost effectiveness of the space elevator for bringing cargo into space, but what about the reverse, bringing material from space to the earh. If one had a mining operation on an asteroid would it be better to send the ore to earth through the space elevator or a more common re-entry capsule?

  • @d6shoup Actually it might be cheaper to have it on the elevator. Use it as a counter weight (in some designs, I'm reminded of the early sea transport that would take folk and supplies to the colonies and stones back for balace). However dropping it in an ocean or bringing it on a craft would require fuel and recovery.

  • Japan is making one.

  • I've looked over another space elevator climb tests video don at MIT in 2005. I noticed that the cable had some slack and wobble to it. Do you think this would this re occur in our future space cables? How can we prevent this problem?

  • @jmacri remember that the ribbon in that video was made from silk and hung from a rooftop, a space elevator cable/ribbon is mostly likely going to be made from carbon Buckminsterfullerene nano tubes, at distances stretching over 100 000km (longer than the equator from end to end) it would hardly made a difference to the viewer's perspective than a straight railroad track.

  • cant wait :)

  • How would the suborbital anchor stay in orbit while accomidate payloads going up that exceed several thousand pounds? Would there be some kind of thrust unit behind the actual elevator module providing lift?

    I think the another big challenge to provide enough lift for the elevator to go up while not exerting force of the anchor.

  • The idea is that the weight of the cable itself, being pulled by centrifugal force, will provide sufficient tension to allow the cable to remain aloft, even when very many tons of cargo are placed upon it.

  • @beechamDesign

    Then at the base must be something that weighs in at x amount to that of the payload. Thats alot of pressure on the base and on the cable. NOt only that, but thats a pretty damn heavy anchor (how do we get that up there?unless its the moon?)

    Supposedly carbon nanotubes are many times stronger than steel.

    any good space elevator documentaries out there?

  • I suggest you read "The Fountains of Paradise" by Arthur C Clarke.

  • @beechamDesign What kind of material would they use for this cable?

  • I presume that your depiction of space elevators rising from Europe, Australia and China was for illustration only, as you will be aware that the equator is the only place where they can work.

  • @MarsFKA

    Why could it only work at the equator?

  • A space elevator needs an anchor point in geosynchronous orbit. Also called geostationary orbit, at an altitude of 35,900 km it is equal to Earth's sidereal rotation of 23 hours 56 minutes 4.1 seconds. If such an orbit is circular, a satellite will appear stationary in the sky, which is exactly what a space elevator requires. In any orbit that is inclined to the equator, the satellite will appear to oscillate north and south of the equator in a figure-8. No good for an elevator anchor point.

  • @MarsFKA you do realize though that the space elevator will probably be anchored in the ocean, on a mobile naval platform, to avoid interstellar debris?

  • @TheMushopiaChannel Indeed, there is no reason why an elevator should not work from a site in the open ocean, considering that the elevator cable is not actually attached to Earth, but in orbit around it. The cable is located above the equator, with its center of mass at the geo-synchronous orbit altitude of 37,300 kilometres, making it, in effect, a satellite that extends right down to the planet's surface. Orbiting debris will be a constant hazard, regardless of where the cable is located

  • Very nice! What fonts did you use?

  • I used "Folio" (from Linotype) and "Enigmatic"

  • Why must one be first? People are still deluded about technology. Nobody should try to compete. We should work together. Together we have 20 fold the ressources. There is no need for "lead". We've had enough of this shitty competition thinking which hinders rapid development.

  • Its true that working together can lead to great things... such as the international space station. In an ideal world, this is how all human acheivements would come about.

    However, if we look back to the 1960s, the era of the greatest strides in space technology, it was intense competition that was spurring rapid development. Without this motivation, governments aren't as willing to fund space programs, and progress takes a back-seat to maintaining the status-quo.

  • On the contrary competition thinking is what spurs development. Most of the technological advances of the 20th century came out of competition of some form, be it war, the space race or simple business competition. There is nothing that makes men strive more to create and improve than conflict.

  • super super super strong cable

  • i don't see how it could work with all the debris in space, you would be bound to hit something eventually.
