I think once its built, elevate up loads more cable and landers quick before a bit of space debris hits it and don't just have 1 cable have about 9 so even if 1 gets hit you've got 8 more and get the lift to drag down replacement cables on the way down,.
Only problem I can see is as you tug on the elevator cable, won't you deorbit your satellite?
@kayaking4autism good question. this is my opinion so I wouldn't hold it as gospel. I think the weight of the lifting body's travelling up and down the tether would be negligible to the overall weight of the entire structure (think of a couple of ants climbing a vine). I suppose one way to increase the load carrying capability would be to extend the range of the tether creating a greater centrifugal force to counteract added weight.
@MrDenniski Also if you put the space elevator at altitudes above 14,000km (GEO) the spin of the Earth itself would yank on the cable and even if it didn't snap it would yoink the satellite into an eliptical orbit and thus slackening the cable. I think the "top floor" would need a lot of fuel and rockets in every direction to keep it in place every time wind blows on the cable, every time some fatso goes up etc.
I think we need one more piece of transitional technology to get to a space elevator: Nuclear lifters. Chemical rockets can only provide so much energy. The Rover/NERVA engines have demonstrated twice the power of chemical rockets, which means bigger payloads, wider safety margins, and making impossible missions achievable. Even with nano-technology, over 20,000 miles of cable is going to require heavy lift capability.

@SunHail8 - You mean like the elliptic orbits our current geosynchronous satellites go through? Which is why you have to re-aim your dish antenna every fifteen minutes? Oh wait - you don't. That's because they geosynchronous satellites don't have elliptic orbits. From the ground perspective, they are locked into place. Adding the cable and counterweight doesn't change the orbital dynamics one bit. Now resonance, the "plucked guitar string" effect, on the other hand, may be an issue.
@SunHail8 - Huh? Well, most of them. 80 - 1.2 k miles is mostly Earth observation. Spy sats, weather, mapping and crops. From 1.2 k miles to 6k miles or so is mostly science - some physics, some astronomical, some large-scale Earth observation. From 6k to 12k miles, you'll find stuff like GPS. 22.2k miles is geosynchronous. And we don't much use orbits past that point. So - in answer to your query, most of the useful orbits are within the GEO orbit - with the highest concentration fairly close.
@47f0 hmmm... you missed what i was talking about: rope to reach down to Earth's surface from satellite needs to be continued through dozens of elliptic orbits. Just assume rope as chain of the balls goes from satellite to surface, what each ball will do???
@SunHail8 - You seem to view orbits as a kind of railroad track in space. Oops, we bumped into an elliptical orbit, guess we'll have to orbit elliptically. It's absolutely within orbital mechanics for an object to have a circular orbit at any altitude. Nothing weird happens when an object in a circular orbit crosses the path of an object in an elliptical orbit. It just continues on its circular orbit - at least, as long as the two objects don't occupy the same space at the same time.
@47f0 in short, you think that angular velocity of each orbit has the same value. please, my friend, spend some time to read how to compute orbit through velocity of satellite.
@SunHail8 - Really? That's what I think? Interesting. What does that have to do with the elliptic vs. circular orbit? An orbit is a path which is a balance between a the tangential velocity of a free object vs. it's gravitational attraction - which happens to be A) not necessarily elliptical, and B) Not applicable to tethered systems. Every piece of the space elevator inside of 22.2k miles is moving too slowly to orbit. But that's okay.
@47f0 well, let's look to the situation in the more details: GEO's orbital velocity == 3.1 km/s, but below GEO, this speed isn't orbital at all. in short, payload will freely fall to the Earth, this free falling must be stopped with additional force, not of just kinetic energy of satellite. as i said, satellite has to use quite powerful thrusters to keep own orbit on. and Yep -- elliptic orbits don't belong to our case, my fault. however i think you'll be agreed this way is to waste $:-)

@toogoodbw I respect u and no offense but atheism is mostly pushed for by people for political reasons. If theres no 1 higher to account to, leaders can press for more and more inhumane laws.atheist tend to be self diluted, arogant and stupid, their beliefs are based on a man that went insane and ate his own shit. Now to prove a point I dnt actualy feel tht way but now u know how it feels for a pompus ass to degrade u just cauz his need to give an opinion is valued more than anothers feelings.
@flyingfoo99 I mostly agree with you about atheism. I would not call myself an atheist. However, I do not believe in a god who intercedes in our lives. If eternal life is real then what is 80 -100 years here on earth? It is irrelevant. God has no reason to intercede. Surely there is more to gain by God not intercedeing then if here were to give into our wants/needs. Suffering here on earth is nothing when compared to eternal life. I know I write it in a confusing way. I hope you understand.
@flyingfoo99 - "I respect u and no offense but atheism is mostly pushed for by people for political reasons."
.
If atheism is being "pushed" it is ENTIRELY for political reasons. As an atheist, I really don't give a damn what kind of silly thing you believe. That is, until you start trying to teach my grandchildren in science class that Jesus rode a dinosaur. Or until you start trying to rewrite the Constitution so it reads like Leviticus. At that point, yes, you'll see solid atheist push-back
What I don't understand why everybody are sticking to those carbon nanotubes? Three decades ago Paul Birch suggests special constructs for such kind of structures called dynamic compression members. In short it can be constructed from usual materials like kevlar or steel. It relies not on mechanical strength of material but on electrodynamic strength of magnetic particles's flow. This technology will be applicable to any megastructures.
@DmAlexeyev I think its because materials apply different to electrodynamics carbon especially. Yes it could be done with steel & Kevlar assuming. The overall structure would still be lighter & stronger with carbon fiber. We could be seeing the beginning of the end for steel & other materials. This nano tube science has everyone scrambling for applications & usage. We are seeing the birth of Unobtainium :)
@dylanlp1999 You know we have a new law similar to Moore's Law but it applys to Modern Health Medicine. Every 2 years we now learn what we learned over the entire history. 20 years from now we may be able to manufacture all needed break throughs in order to achieve life for ever for all. This technology expansion is accelerating faster and faster every day. I would not be surprised if we achieve some miracle break throughs with the LHC and existing world science discovery programs here shortly!
The really big question is whether this cable can withstand something hitting it. Every satellite spends part of its time over the Northern Hemisphere and part of it over the Southern. If it makes this crossing at precisely the wrong time it can hit the cable and disasters happen. The top end flies away and the lower part falls - on what? And what happens to whatever was climbing the cable at the time.
@Wizardess - "And what happens to whatever was climbing the cable at the time"
.
Depends on where the break occurred. The most likely break is in low Earth orbit - within a couple hundred miles of the surface, because that's where most of the orbital junk is. Since the climbers will be at some random point on a 23,000 mile-long cable, the odds of the climber being below that level at the time of the break are less than 1%, and if they were, would fall within 200 miles to the west of the base.
@Wizardess the chances of anything hitting it are pretty slim, and besides the idea would be to have it anchored to a movable oil-rig kind of structure so its orbit can be modified in the event that a satellites trajectory would cross within its airspace. A much more likely end to the space elevator would be project cancellation before its even built
@Wizardess Dude, there are literally hundreds of satellites up there in space, so howcome they havn't collided with each other? Because we can program them to avoid each other, plus, satellites have manuverable thrusters, in case they lose their altitudes, we can just activated from the surface, so it will reenter its orbit. A space elevator wouldn't be as fragile as most people think, which is probably why our space agencies are hesitant to build one or fund private companies to work on it.
@Wizardess Well, I know that carbon nanotubes have been measured at strengths of 400 times stronger than steel, pound for pound. This makes it potentially the strongest material known in the universe. It certainly seems like a promising material. But yes, your question is certainly an important question.
every country in the world should unite in this project it would become our greatest achievement a monument to human ingenuity. plus cheap hollidays to space
The company working on the Space Elevator is called Liftport Group. They have the world's largest carbon nanotube factory and they are testing climbers on Kevlar ribbon cables. It has been a while since I checked their progress, but they were climbing almost 1 mile on balloon tethered cables. They're testing laser power transmission, too. All for defense apps short term.
if they have about 5 cables instead of 1 that would reduce the tension and give it more secuirty so that the station doesnt break up and go into space
@jukio02 No because they are talking about strength compared to weight. for example steel can only hold up about 20 to 30 miles of itself, while carbon nanotubes (at current technology) can hold up 5000-6000 miles of itself. No matter how thick you make it steel can still only hold up 20 to 30 miles of itself because you get more weight. just as a side comment they may make 2 cables, one as the rope for the climber and one to supply power to the climber
Yes, the cable will weigh a lot - how much depends on how much load you want to carry. You need a material with enough specific strength to carry its own weight, and the climbers, without snapping. Right now, only carbon nanotubes are theoretically strong enough to do the job.
@TedSemon Carbon Nanotubes are amazing however I believe Boron Nitride nanotubes also have the right properties. They are second only to carbon nanotubes in strength and has some different chemical properties such as being an electrical insulator.
WAAAH!!! It won't work! WAAAH!!! It's impossible! WAAAH!!! It's too dangerous! WAAAH!!! It's too costly! WAAAH!!! We have other problems! WAAAH!!! WAAAAAAH FUCKING WAAAAAAH!!!
Anyone thought of all the space debri floating around up there,and asteroids as pointed out by Mr juno06,there is apparently millions of tons of crap floating around up there that could sever any line they place there.
@yogi1707 : Clearing the space junk orbiting Earth, or at least a large portion of it, would be one of the preliminary steps. Sort of like clearing the brush before building a house. It wouldn't be easy, but if we can figure out how to build a 100,000 km cable from carbon nanotubes, we can probably handle the clean-up. :)
@yogi1707 it's not a single line of carbon nanotubes. its design calls for thinning near the earth so that it weighs less and thicker higher up where asteroids or other debris may hit. Even though its thicker the farther you go out, it wont add more weight bc of the weightlessness of something falling around earth (its going to be at a geosynchronous orbit)
In theary it would cost a airplane ticket but one elevator for mabby the 4 billion people who want to go in to space? People will charge alot for that.
@1good100 if you bulid one, the second one will be about 10% as expensive,...at current standards the elevator will cost around 15 billion dollars, which may sound like alot, but for a government is pretty much chump change for the economic boost it may give. The second or however many more we *MAY* make, would cost roughly a few billion dollars.
half a billion dollars to go the moon? i could make a steven spielberg film of me being on the moon, pay off all the people involved and keep it a secret for 100+ years.
Uhmwpe is a acronym for ultra high molecular weight polyethylene and is marketed as 'spectra' and is the strongest synthetic fiber available. We need it to have a molecular weight of 6000000 amu
it will be like a yoyo to the earth. you put a station in synchronous orbit and you extend the station to another 30000miles to compensate the gravity of the cable itself. Once thats done you add more gravity to the end of the yoyo by taking the first cargo to the top of the cable.
Then we can finally make large launch platforms and factories into orbit and industrialize space from there on.
Once we can make 1 elevator, the next elevator will eb way cheaper.
@NMEdrone Probably be the longest elevator ride of your life... a few hours. It takes 6 hours to dive from the surface to Titanic because of pressure build up. Since pressure is decreasing, the elevator can mover faster (although it is probably has several hundred miles to travel).
so is it realy that easy? send a satellite to orbit and drop a long ass cable then tada bitches we got a space elevator.....i think not but i bet we'll have one possibly in 10-15 years.. 5 even if bill gates invests in it
@xmamoneyx It will be hard to make a strong enough cable, but that is the only technical problem. Everything else we can do right now, if someone provided the money.
@TheRealCartoon ive heard that carbon nanotubes could possibly be strong enough to build it, but the actual construction would be sight to see like would it be possible to actually just drop the nanotubes to the ground without sumthin happenin to them if so bill gated better send a good 100mill, but i dont think it would be too ,much to build one
This elevator would fail because of the violent weather in the entire atmosphere (as the cable is extremely light, it would not take much to upset the balance) and Newtons third law: every action has an equal and opposite reaction. As the elevator goes up, the satelite goes down, unless it has something to counteract the force produced by the elevator. But then it wouldn't be so cheap anymore, would it?
@manbearpig91 - that's exactly what I was talking about, if it pulls itself up, the satelite will come down unless it has thrusters. You know that they demonstrated the concept with a balloon filled with helium and attached to it, a cable and an elevator with solar panels. The balloon uses a constant force due to the difference in density with air. The satelite would have to have a force against the pull of the elevator.
@manbearpig91 - For such a long distance? I don't think it will be unaffected by the constant pull of the elevator. You must also think about the cable. Even with a relatively light cable, the mass would be enormous anyway, and it would be pulled by the earth's gravity, wouldn't it? And would a satelite with such a mass ever go into space without some new technology? And wouldn't the satelite tilt as the cable comes down to earth?
@simily22 - So you think that just because it's orbiting it will not change its trajectory? Think about this: the satelite is in orbit with the cable still inside, and it has mass m. As the cable is rolled out, the satelite has less and less mass. The trajectory will therefore change: it's orbit will not be geostationary anymore. And think about the rest of the comments. I'm open to all ideas, but this one hasn't convinced me yet.
@Archimedes555453525 There is a component left out in the video. You have the cable, the lift car, the satellite in geosync orbit serving as the end station and transit point and then further out you attach a weight. A small asteroid would do just fine. This will pull at the cable to keep it taunt and you can adjust its orbit to keep the pull and force constant.
@kokofan50 - Then I guess we need one HEAVY satelite. And even then, the effects would be the same, only at a smaller scale. I think the idea of the space elevator is brilliant, but it needs more elaboration. But hey, if this is possible, then it should be made, as long as it doens't harm our beautiful planet in any way.
@Archimedes555453525 i think that the people planing to build one have done the mathas to what we need to keep it up. I think you should care more about whats happening to the planet now more than what that would do
@bcta302 if we could harvest resources from other planets then the supply of minerals wouldn't be an issue, but it's getting to the minerals, delivering them back to earth and refining them that would be a problem, and that would 'cost' a lot, in terms of fuel and money
the problem is that energy can not be created it can only be transformed from one form to another. the efficiency of transforming chemical battary energy to electrical then mechanical energy is very low, compared to normal combustion engines.
it would take thousands of battery to make an electrical vehicle run like a 4 cylinder engine car
@bcta302 i think nasa should make electric space vheicles too, they would probably harvest solar power in the form of solar sails, but the only problem with that is that the sun is to far away to produce any meaningful power
@jesman1985 Seriously? You have religious objections to a more energy efficient method of doing something we've been doing for over half a century? I've been following the development of the precursors to a space elevator for years, and this is the first time that I've heard "It'll make God mad" presented as an objection.
@Datan0de lolol.. woow.. thats not quite what i was saying.. in babylon they did that for the reason of purposely reaching God.. is that our reason? im just pointing out the obvious that it looks familiar.. take it how you want.. and truth be told. i feel that the technology of civilization before the great flood were much more advanced than ours today.. were how old as a civilization vs? but on a different note.. i think our $ could go somewhere much more productive than for the time being..
@SirMaximus21 Yeah man it would start of melodic with an ever incresing ryhtem as the elevator progreses then finally when it hits the top full blown slamers with everyone Hard STOMpIN AND SpaZin out woop woop,Lucozade's halfway up cant wait!!!!
To be able to supply the space station efficiently and fast. To eventually lead to the colonization of mars and other planets. To further our scientific knowledge. To develop a material that can withstand this time of tension which would then lead to other practical scientific advancements that would help and enhance the lives of industrialized nation's citizens and potential provide more cost effective materials to provide for third world countries.
If any of you had any idea how aerospace companies operate these days, you would realize that the cost of access to space could be significantly reduced just with companies that operate WAY more efficiently and employ technologies that don't have as much fatty (expensive) manufacturing processes behind them.
@5600981 Don't compare the space elevator to airplanes. That's like comparing an apple to an entire orange grove...that grows in the tundra...outside.
Planes have ample historical precedent in birds, insects, etc... Space elevators have absolutely none of the such. Don't just spout off statements like that thinking it's always clever. You'd also help your cause if you spelled 'said' correctly.
@5600981 Well, I think the internet does have historical precedent on a fundamental level in the human brain. Regardless, you are right that it is a weak argument. If you want some serious issues with the space elevator, I will list them for you--at least the ones I know.
@gosale1 Proponents of the space elevator don't do any of the math behind the idea. Not only is the space elevator incredibly far-fetched technologically, it is also impractical in a lot of ways outside of engineering. If someone asks I will list a few.
Do any of you space elevator fans know what a polar orbit is? How about a Molniya orbit? Hell, even a low inclination low earth orbit? Most satellites sent up would still require conventional launch vehicles to get them into the right orbit.
So do you know how much delta V it would take to get a satellite from a geostationary orbit to a polar low earth orbit? A 90 degree plane change is an incredibly costly maneuver in terms of energy required.
Carbon nanotubes are great and all but with the discovery/invention of Graphene. We'll, all I can think if now is the possibility of Graphene reinforced carbon nanotubes :3

@Jerusrad I respect your beliefs; however, you do realize that nearly every language being spoken today is not that old (relative even to the bible timeline). They are all variations and mixtures of other languages, most of which are dead now. If you seperate groups of people from each other they start to speak differently. Do it long enough and you have a different language. For the record I do think that ganjahyute's comment was uncalled for an very rude. Tower of Babel is probably BS.

@flyingfoo99 I mostly agree with you about atheism. I would not call myself an atheist. However, I do not believe in a god who intercedes in our lives. If eternal life is real then what is 80 -100 years here on earth? It is irrelevant. God has no reason to intercede. Surely there is more to gain by God not intercedeing then if here were to give into our wants/needs. Suffering here on earth is nothing when compared to eternal life. I know I write it in a confusing way. I hope you understand.

If atheism is being "pushed" it is ENTIRELY for political reasons. As an atheist, I really don't give a damn what kind of silly thing you believe. That is, until you start trying to teach my grandchildren in science class that Jesus rode a dinosaur. Or until you start trying to rewrite the Constitution so it reads like Leviticus. At that point, yes, you'll see solid atheist push-back

What I don't understand why everybody are sticking to those carbon nanotubes? Three decades ago Paul Birch suggests special constructs for such kind of structures called dynamic compression members. In short it can be constructed from usual materials like kevlar or steel. It relies not on mechanical strength of material but on electrodynamic strength of magnetic particles's flow. This technology will be applicable to any megastructures.
DmAlexeyev 5 months ago
@DmAlexeyev I think its because materials apply different to electrodynamics carbon especially. Yes it could be done with steel & Kevlar assuming. The overall structure would still be lighter & stronger with carbon fiber. We could be seeing the beginning of the end for steel & other materials. This nano tube science has everyone scrambling for applications & usage. We are seeing the birth of Unobtainium :)

The really big question is whether this cable can withstand something hitting it. Every satellite spends part of its time over the Northern Hemisphere and part of it over the Southern. If it makes this crossing at precisely the wrong time it can hit the cable and disasters happen. The top end flies away and the lower part falls - on what? And what happens to whatever was climbing the cable at the time.

@Wizardess everything fails eventually but that should not stop us from moving forward. No matter the cost.

@Wizardess - "And what happens to whatever was climbing the cable at the time"
.
Depends on where the break occurred. The most likely break is in low Earth orbit - within a couple hundred miles of the surface, because that's where most of the orbital junk is. Since the climbers will be at some random point on a 23,000 mile-long cable, the odds of the climber being below that level at the time of the break are less than 1%, and if they were, would fall within 200 miles to the west of the base.
47f0 2 months ago
@Wizardess the chances of anything hitting it are pretty slim, and besides the idea would be to have it anchored to a movable oil-rig kind of structure so its orbit can be modified in the event that a satellites trajectory would cross within its airspace. A much more likely end to the space elevator would be project cancellation before its even built
MrDenniski 2 months ago
@Wizardess Dude, there are literally hundreds of satellites up there in space, so howcome they havn't collided with each other? Because we can program them to avoid each other, plus, satellites have manuverable thrusters, in case they lose their altitudes, we can just activated from the surface, so it will reenter its orbit. A space elevator wouldn't be as fragile as most people think, which is probably why our space agencies are hesitant to build one or fund private companies to work on it.

jukio02 10 months ago
@jukio02 No because they are talking about strength compared to weight. for example steel can only hold up about 20 to 30 miles of itself, while carbon nanotubes (at current technology) can hold up 5000-6000 miles of itself. No matter how thick you make it steel can still only hold up 20 to 30 miles of itself because you get more weight. just as a side comment they may make 2 cables, one as the rope for the climber and one to supply power to the climber

Yes, the cable will weigh a lot - how much depends on how much load you want to carry. You need a material with enough specific strength to carry its own weight, and the climbers, without snapping. Right now, only carbon nanotubes are theoretically strong enough to do the job.

rjpugh 1 year ago
@yogi1707 it's not a single line of carbon nanotubes. its design calls for thinning near the earth so that it weighs less and thicker higher up where asteroids or other debris may hit. Even though its thicker the farther you go out, it wont add more weight bc of the weightlessness of something falling around earth (its going to be at a geosynchronous orbit)

it will be like a yoyo to the earth. you put a station in synchronous orbit and you extend the station to another 30000miles to compensate the gravity of the cable itself. Once thats done you add more gravity to the end of the yoyo by taking the first cargo to the top of the cable.
Then we can finally make large launch platforms and factories into orbit and industrialize space from there on.
Once we can make 1 elevator, the next elevator will eb way cheaper.

xmamoneyx 1 year ago
This elevator would fail because of the violent weather in the entire atmosphere (as the cable is extremely light, it would not take much to upset the balance) and Newtons third law: every action has an equal and opposite reaction. As the elevator goes up, the satelite goes down, unless it has something to counteract the force produced by the elevator. But then it wouldn't be so cheap anymore, would it?
Archimedes555453525 1 year ago
@Archimedes555453525 what if the cable and satellite dont move, and the car or elevator climbed the wire by its own power? perhaps solar panels?
manbearpig91 1 year ago
@manbearpig91 - that's exactly what I was talking about, if it pulls itself up, the satelite will come down unless it has thrusters. You know that they demonstrated the concept with a balloon filled with helium and attached to it, a cable and an elevator with solar panels. The balloon uses a constant force due to the difference in density with air. The satelite would have to have a force against the pull of the elevator.
Archimedes555453525 1 year ago
@Archimedes555453525 won't the centrifical force from being in orbit of the much larger and heaver elevator be enough to keep it in orbit?
manbearpig91 1 year ago
@manbearpig91 - For such a long distance? I don't think it will be unaffected by the constant pull of the elevator. You must also think about the cable. Even with a relatively light cable, the mass would be enormous anyway, and it would be pulled by the earth's gravity, wouldn't it? And would a satelite with such a mass ever go into space without some new technology? And wouldn't the satelite tilt as the cable comes down to earth?
Archimedes555453525 1 year ago
@Archimedes555453525 the satelite is orbiting my friend!
simily22 1 year ago
@simily22 - So you think that just because it's orbiting it will not change its trajectory? Think about this: the satelite is in orbit with the cable still inside, and it has mass m. As the cable is rolled out, the satelite has less and less mass. The trajectory will therefore change: it's orbit will not be geostationary anymore. And think about the rest of the comments. I'm open to all ideas, but this one hasn't convinced me yet.
Archimedes555453525 1 year ago
@Archimedes555453525 There is a component left out in the video. You have the cable, the lift car, the satellite in geosync orbit serving as the end station and transit point and then further out you attach a weight. A small asteroid would do just fine. This will pull at the cable to keep it taunt and you can adjust its orbit to keep the pull and force constant.

One Cable can not be the idea.
Lets say this, if you were on the elevator, say going downwards, and the elevator all of a sudden, cuts a peice of the cable.
It would cause a tremendous failure and cause the ring to collapse.
My Idea, add support rings around it, just like the one from Halo, so that it wouldnt cut off and be sucked upward in a sub-space vortex.
Cause that will lead to a unplotted orbit around the earth. And might crash land somewhere, where lots a people are at.

Do any of you space elevator fans know what a polar orbit is? How about a Molniya orbit? Hell, even a low inclination low earth orbit? Most satellites sent up would still require conventional launch vehicles to get them into the right orbit.

Sure, but at that point you have a 'delivery vehicle' that takes the satelite from the elevator to its new location.
