Japanese Begin Working On Space Elevator Anonymous Mon Sep 22 18:49:41 2008 No.1351311 [Reply] [Original]

From cyborg housemaids and waterpowered cars to dog translators and rocket boots, Japanese boffins have racked up plenty of near-misses in the quest to turn science fiction into reality.

Now the finest scientific minds of Japan are devoting themselves to cracking the greatest sci-fi vision of all: the space elevator. Man has so far conquered space by painfully and inefficiently blasting himself out of the atmosphere but the 21st century should bring a more leisurely ride to the final frontier.

Japan is hosting an international conference in November to draw up a timetable for the machine.

Also, some US companies have been working on the carbon-carbon nanotubes for the anchor for a few years.

A project of this scale will require international cooperation

Mr. Weeaboo's racist comments above ignore the fact that Asian cultures by their deliberate emphasis of the group of the individual stifle the sort of creativity we in the West value and has provided the vision for all the tech toys the Japs have made

>Current technology is not capable of manufacturing materials that are sufficiently strong and light to build an Earth based space elevator as the total mass of conventional materials needed to construct such a structure would be far too great. Recent proposals for a space elevator are notable in their plans to use carbon nanotube-based materials as the tensile element in the tether design, since the theoretical strength of carbon nanotubes appears great enough to make this practical. Current technology may be able to support elevators in other locations in the solar system however, and other designs for space elevators exist that use current materials.

>Cable strength

>The current strength/mass ratio of cables of any construction is inadequate to build a space elevator at the present time. Although carbon nanotubes embedded in the tether would give it enough strength to be practical, nanotubes of sufficient length have not yet been made.

>Theoretical objections have been raised to manufacturing bulk carbon nanotube structures with strengths approaching that which simple models and microscopic strengths suggest. H. K. D. H. Bhadeshia argues that the presence of defects would significantly reduce the strength actually attainable.

When Clark first proposed this idea there simply was no way to make such an engineering feat. I was not aware of the carbon nanotubes idea but as far as I was aware current technology made this idea completely impossible. My statement >>1351385 was based on the knowledge I had of the current technological ability of the world.

Whether these nanotubes can strong enough to withstand the tidal pull such an object would create and light enough to keep it from collapsing on it's own weight remains to be seen.

I doubt this would work, they do know how to produce the materials or how to construct it, theory is one thing but actually building it is much more difficult. I'd say they go back to trying to make a mile wide solar panel satellite to send into orbit around the sun to collect solar energy and send the energy by microwave to a receiver on earth. 5 trillion yen? looks like Strategic Defense Initiative aka Star Wars all over again, the whole project is probably used to divert government funds for their own spending anyways HOORAY democracy and government corruption, this is why communism is superior.

thats centripetal acceleration not centrifugal force, the planet is constantly rotating the rotational energy will get transferred to the nano carbon elevator rope, since the elevator rope is flexible it would begin to twist, the situation is comparable to a swing being twisted by a force.

That's exactly what happened in Clark's story. Except being made of nanotubes it would be like a whole buliding made out of diamond. Clark reckons you would need nukes to sever the tower.

Note that also, if you manage to destroy the base of the space elevator, it will just hang there in the air. The forces on either wide of the half-way station balance each other out.

It will hang in the air because it's not a very very tall building, it's actually a very very long geosynchronous satellite.

Think about it, how is it built? Well first you place a geosynchronous satellite in orbit, then you start building the track on either side (earthward and spaceward) of the satellite so that the forces on either side remains balanced and the satellite maintains it's geosynchronous orbit. Keep going until the earth end reaches the ground. Yeah sure the ground end is now tethered to the ground, but the whole damn structure is still essentually a geosynchronous satellite and if you cut the ground end it will still just float there in space.

>What about if we just float rockets using hydrogen balloon, and then high up in the edges of the atmosphere then fire the rockets?

weight of one cubic feet of air = 1.2041 kg
weight of space shuttle = 2,029,203 KG
and this is not including the rocket boosters! and you have to add more force to make up for the weight of the balloon

You would need to make a balloon that 2029203/1.2041 square meters large to be able to float a space shuttle not to mention the balloons need to survive the rough conditions of the ionosphere. It would actually cost more money to construct and fill this fail balloon than our current method.

Yes there is, there difference isn't that great but it's there. This is why if the whole space elevator was just midway station and tracks the spaceward track would have to be slightly longer than earthward track to balance the acceleration.

Improved plans for the space elevator include a counterweight at the space end, to reduce the length of the spaceward track. It could either just be some space rock that is captured for the purpose, or a full on space station that have sections added to it to increase mass as the earthward track is being built.

Well, first you send up a large number of long-range spacecraft with interplantary capabilities, and send them to rendevous at the nearest suitable specimin. Then landers would be sent down to survey the area. Once the asteroid has been suitably mapped out, the thermonuclear warheads are attatched at precise locations, where they are detonated remotely, thus sending the asteroid on a finely calculated trajectory into near-earth orbit, where it can be suitably used for purposes at hand.

You don't have to capturing an asteroid for counterweight. You can just keep adding tracks to the space end then fix a small ISS style space station to the end.

People want to capturing a counterweight because it saves them the rockets that would otherwise be needed to lift that mass out of the Earth's gravity well.

Dear builders of the Space Elevator,

If you need sperms for the construction of this glorious Elevator, then I am your man. Please contact me if you'd requrie my sperms. Spearm is a liquid, and you could probably use it for oil or maybe some type of coolant liquid. I highly recommend the use of sperms with Space Elevators. Please contact me at the 4chan if you are interested in using my sperms for this project.

Thank you gentlemen.

No there isn't, there are geosynchronous orbits, but those make a figure 8 in the sky. Only geostationary is perfectly still in the sky (except for the orbital perturbations).

A geostationary orbit (GEO) is a geosynchronous orbit directly above the Earth's equator (0° latitude), with a period equal to the Earth's rotational period and an orbital eccentricity of approximately zero.

In other words, geostationary orbit is a subset of geosynchronous orbit, which is directly above the equator, and is the only suitable orbit for a space elevator.

You do know that such structures aren't rigid? It wouldn't have to be perfectly geostationary to work. You might have the astrophysics background, but I have an architectural background. Depending on how much the orbit differs from the location on the Earth, the structure could support it.

Way to sound like a retard. A "civil engineer" has a little bit of specialization in that, but also does city planning, landscaping, other things, etc. "Structural Engineer" isn't a position I've heard of, but probably is more of an inspector thing. "Architectural Engineers" are the people that get the drafts from the architects, then use physics and mathematics to determine which materials and construction methods have to be used to make the building stand. They are the ones directly responsible if the building falls down (provided it wasn't a fuck up on the constructor's part).

Next time you try to insult someone by saying that their field of study doesn't exist, you might wanna make sure that you're not just wrong.

I can tell you that to do ARCE, you need to know everything there is to know about structural integrity.

USE FUCKING MAGENETISM.
Its simple enough to have multiple stages with magnetic fields and shield the interior of the elevator against the field. You could slowly accelerate to incredible speeds.. like a slow railgun in a way.. similarily you could also decelerate nicely and get back down easily with assist by reversing polarity.

What I mean is: Build a shaft, but instead of worrying about ropes and tension use magnetism for the propellant between stages, every few stories is a electromagnet that reacts to a magnet on the elevator itself. that way you can bypass rope tension and maintenance issues.
