Carbon nanotube ribbons held together by nothing but the van der Waals force are less than one thousandth the thickness of your hair and are stronger than steel.

How would you use an inert gas as a fuel?

Not at all. It's too small and too far away to cast a shadow that far down(assuming you're talking about the top). The atmosphere refracts light all over the place below the object, which is why the sky is blue during the day btw.

You wouldn't. I was saying, we could create more Helium which we are in a shortage of once Fusion plants go online. Worded it badly.

Reminds me of Gundam 00. Now all we need is GN drives and humanity will be set to fight aliens.

[quote name="wedge" url="/t/1222564/th-japanese-firm-to-build-space-elevator#post_16589839"][QUOTE]The elevator is expected to be able to carry up to 30 people at a time, but don't expect to be able to hop on it spontaneously. Obayashi said that the elevator may be traveling at a speed of 200 km/h (124 MPH), which means that the a one-way trip will take about 180 hours or 7.5 days. [URL=http://www.overclock.net/image/id/1912505/width/250/height/482][IMG]http://www.overclock.net/image/id/1912505/width/250/height/482[/IMG][/URL][/QUOTE] [URL=http://www.tomsguide.com/us/japanese-space-elevator-sci-fi-carbon-nanotubes,news-14259.html]Source[/URL] How cool is that? It would be way more efficient to use this elevator to exit the Earth's gravity, then launch shuttles that are already in space to the moon or mars or anywhere else.[/quote]

 

 

Can everyone please look at the diagram again. This is obviously a translation error. The earth itself is (approximaty) 12,742 kilometers wide, why on earth would someone want to make a tether seven and a half times the width of the planet itself? It is obviously meant to be 96,000 METERS.

 

Also, wouldn't it be great if they just used it as a way to generate nuclear electricity off planet? If anything goes wrong you just eject it into space! That someone is looking at this seriously is the best news I've ever heard in my entire life.

The existence of an elevator would make it possible to build large modules (like US aircraft carriers) on Earth and send them into orbit to build space stations and ships, we could mine titanium from the moon.

it was incompetency at management that caused those rockets to break up. not some random act of god.

challenger - ignored warnings from engineers that o rings would fail under cold temperatures of the launch
columbia - ignored damages to the shuttle after several flights cuz "dint cause no problem befur"

Edit: Oh, and question. What happens when they build this thing and there is another massive earthquake/tsunami? Will the elevator rip from the ground and float off into space?

I like how you assumed that just because it's a Japanese company they must execute the plan in Japan.

ILoveHighDPI, geostationary orbit is at 36k km. not 36 km but 36000. counter weight height is written correctly
