Space Elevators: Low Cost Ticket to GEO?

Space 429

Crocuta writes "The current issue of Science News features a cover story that discusses the current developments in space elevator technology. NASA has been working on such devices for many years, but private companies such as Highlift Systems are now jumping on the space elevator bandwagon, no doubt seeing the huge potential profit in a low cost per pound delivery system. PhysicsWeb has a somewhat older, but much more technical article on the formation and structure of the carbon nanotubes that form the basis of the proposed tether cables. With a development like this, we could shoot entire boy bands into space and make the world a better place."

Egenia Loli is a fat PIs stop her NOW STOP HER (-1, Troll)

Anonymous Coward | more than 11 years ago | (#4411433)

PLEASE STOP REPOSTING OSNEWS PLEASE

Ok. I am really getting tired of Slashdot reposting the crap rag OSNEWS on here. Please, PLEASE stop "editors". I don't know which of you has a fetish for Eugenia Loli, but this is supposed to be a Nerds site, not a technically impaired idiot site. Please, I implore you, please, STOP RE-POSTING OSNews *Crap* here. Here stuff is devoid of technical cross examinations, rife with conjecture and poor spelling and grammar, and she does what has long been disallowed here, the censoring of Anonymous Cowards. It is bad enough Slashdot isn't critically edited or reviewed, but in the absence of recourse by a commenting public free from censorship and suppression, OSNews is a totalitarian one way street. Please consider that she is likely to be getting kickback to review and announce things, and with her one way system, she could very well be lying to suit the needs of her underwriters without having recourse.


Eugenia Loli needs to exposed. I will post 3 articles that show how fascist the Greeks can be, and that people like Eugenia perpetrate. Then I will cover My Big Fat GReek Wedding, with Fat being the operative word. Then some random Eugenia quotes. I hate you Eugenia, for being a fascist at OSNEWS. You are a pathetic waif who can not accept dissent, and you dictate to your small and withering community. I hope you get ovarian cancer.

Fat Eugenia Loli's Friends Ban all electronig games by mistake. Its people like Eugenia Loli that show that the formerly great state of Greece has erorded into a festering inbred, stupid hairy totalitarian fucks like herself. Now is the fatty greases sweltering out of her cellulite that makes it seem like Grease would be a more apropro name than Greece.

The Night Defender Fat Eugenia Loli Fat

Sweating and farting nervously on the verge of mental meltdown, ELQ reloads each of her precious OSNews pages, making sure all is well. Fifty Internet Explorer windows are open in Windows XP, it's gridning the hard drive to death. ELQ's cable modem and NIC activity LEDs are nearly solid from the raw frenzy of almost constant browser reloading. Eugenia's eyes twitch rapidly from window to window with Mercurial speed to make sure that any rogue comments do not escape her attention, always hitting her refresh buttons with pinpoint accuracy. No logical order for checking, purely random and impulse driven by raw Mediterranean temper, stopping for the occasional savage bite from a pork loin still affixed to the bone, Eugenia's eyes never leave the monitor.

"N-n-n-n NO! No TIME for Dance Dance Revolution, oh but it's been so long! I cannot allow the BASTARD flooders' comments to be seen. MY DOMAIN IS SACRED!"

Hair is frizzled and days unwashed, asscrack just barely half wiped in a frenzy to return to her monitor, having taken a large shit earlier. No time to flush! Her armpits are over-ridden with pubic hair, her fat flaps reek of B.O. and yeast from days of neglect and hour upon hour of sweating. Relentless sweating.

"Cannot to be keeps up this pace! I may be need to go to hospital for exhaustions" she pants in desperation, wiping the sweat from a matted hair lock with her week-old t-shirt offering.

The hour of judgement approaches! Comment number 45 in thread 374 is clearly of anti-Greek sentiment! It reads "Eugenia continues to post yet another story that's simply ripped off from other websites. How much longer can this continue? It's my opinion that she has poor editorial skills. I think they should be revoked."

"YOU BASTARD FUCK!", Eugenia erupts in raw hatred, simultaneously ripping a 120 decibel-at-1-meter fart into the back of her chair. "Nobody is to be attack my site!" Eugenia blasts away at 10 words per minute in a barely-coherant broken English. She's on a mission. After several hours, the words on the screen are completely shattered and in disarray, they make no sense. Eugenia is impressed with her English progress and submits her lousy retort. Relaxing only for several seconds to savor the rush, she continues her patrol, sleepless into the night.


Yup, a self-employed pissing loser with a family, 600 acres of deeded land, several automobiles and a four-story house. What do you have? 2,000 British pounds to your name, a playstation2, some computers and a husband that picks up the tab for everything? That's what I thought, you fucking olive-picking, highboot fecal smear of a bridge troll.

QUIP: Well, what a waste of a good fortune. Assuming that it were true, of course. Which is something that most of us won't do, given your guttermouth rambling and apparent poor breeding.

Taken from OS News posting by Eugenia 03/04/2000 Your post would be a lot more credible if you omitted like every 25th word to simulate your bad english. Actually I didn't even read it at all, isn't that awesome?

Eugenia--

Have you ever taken a step back and looked at your life? Taken a calming deep breath, cleared your head, and
assessed the situation? Looked around at what you have made for yourself, what you've done and how it's affected
you? If you had, it wouldn't be hard to see that things aren't as rosy as most people would be comfortable with;
furthermore, it seems as if you're not comfortable with you or your situation either. It's no large feat to
realize that things in your life are falling apart, and have been for quite a while. In fact, you don't really
seem to have a life now and all that you own or have is going to go away eventually because it's not yours. Yes,
Eugenia, here's the simple, terrible truth: your life is in shambles and it's only getting worse.

Let's take a look at the swill and depravity that you live in.

Your Slashdot journal entry from Saturday, March 02, 2002 encapsulates your attitude toward hygiene (or lack
thereof) in one sordid little pill:

there is only ONE thing I can't stand: The upstairs people. They do things with the water at 6:30 in the
morning, every morning
[I though you had a four story house, you fucking lying fat bitch]

Eugenia, this is known as bathing. The concept may be foreign to your rancid Greek arse but it's a fact of life to millions of Americans everyday. Oops! I forgot you're not an American citizen. Well, we'll touch on that
later...

Here are a few quotes out of your Slashdot journal, taken from Sunday, March 03 through Thursday, March 14, 2002 that do well to exemplify your lack of will-power and discipline.

Today, I started a "real" diet. And yes, this time, the diet IS HERE TO STAY [...] my diet goes well
[...] Diet goes ok, I suppose. I mean, I feel that I do a more balanced diet now, as opposing of losing
weight right here, right now. I hope it continues well [...] I feel a bit weak, but it is not too bad
[...] Argh, I got a terrible headache now [...] I am roasting some pork and oven potatoes


Within just a short eleven-day period we see a rapid downward spiral into fleshly indulgence and lack of self-
control, hastened by physical sickness and ailments resulting from simply eating properly. Your body has attuned
itself so finely to your horrid eating habits that it actually grows ill over these eleven days to the point
that finally, in desperation over a migraine, you cook up a grease-laden meal to satiate your thirst for all
things fat.

Have you no self control? Look at yourself! You have a gut that just won't go away-- you look like an ugly,
stinky, fat little troll even on your wedding day for Christ's sake! Have you no pride or respect for yourself?
Not even just enough to make you stave off those pork and potatoes? Gluttony will destroy your life, Eugenia.
It's already destroyed your body.

Eugenia, it's clear to me (and everyone else) that you're mentally unbalanced and delusional. Please, seek help
immediately. You are in dire need of counseling and/or therapy for a myriad of issues, among which are hygeine,
self-discipline, and proper English grammar. We're behind you all the way, Eugenia, you can do it.

Eugenia: The Fat Fucking Smelly Greek Pig

You fat fucking smelly Greek whore! Do you even wash on the rare occasions when your husband wants to fuck you? I bet your arse smells like a pig farm after eating all of the fucking pork and potatoes you cook-- you do nothing but sit all day, sweating and farting. It must smell like a swamp where criminals dump bodies in the sweltering heat.

Do you even shave? You sound like a lazy fucking wart of a housewife who wouldn't even bother. I bet the place is a mess too: dishes needing done, a layer of dust over everything, and stains and spills here and there. What a fucking pig-- a hairy fucking Greek bitch-pig.

Oh yeah, and your "skills" are laughable. You can't code for shit-- there's more holes in your PHP site than in a Greek brothel. Your English is terrible, which is pathetic for an editor-in-chief of a news site that reports in the language. Your obvious biases and slants make you look even more silly and unprofessional, as well as your multi-paragraph rants and fits of rage you write in your own forums. It's no wonder no one takes you seriously.

In short, ELQ, FUCK YOU. You are a loser, a no-lifer, a wanna-be, and a fecal smear in the world of technology. You are a detriment to the community you claim you serve. I challenge you to refute one thing I have said. You can't; it's all true.

And you know it.


Eugenia, why you're a drain on society.
I am Greek and english is not my native language. We do OSNews for fun (however, OSNews takes most of my time every day), so if you have a problem with my spelling and grammar either a) do not come back (spare us and save your time too) b) send me a proofread version of the article in question. Whining about something I can't radically improve overnight, is not an option.

Ahem, Eugenia. You've been living in English language countries for AT LEAST A DECADE from what I gather. You've spent the last year and a half giggling moronically and getting your bologna tits caught in a wringer after you've been trolled. Here's an idea you smelly twat: Get some advanced ESL text books and read those. Fuck, you've probably spent more time eating the dried phlegm from your nasal cavity than studying English. You are living in an English language nation, and are therefore a burden on society without sufficient language skills. You're not fit to be my house maid, as far as your language skills are concerned. Furthermore, you are a lazy cunt since you've not been motivated to do this relatively simple task as of yet. Please stop polluting the technology/operating system scene with your garbage writing, you seek out the spotlight like a fucking tomahawk missile seeks heat. It's PATHETIC! Get English text books and get a fucking life you stupid little olive-smuggling whore!

In case Eugenia Loli-Queru is reading
Brilliant. Absolutely brilliant. Next week on OSNews she's going to review a commercial floppy disk formatting program. She gives it 95%. DUMB CUNT.


Greeks ban electronic games by mistake
Beware Greeks writing laws
By Adamson Rust: Sunday 01 September 2002, 17:40

ONE OF THE SO-CALLED CRADLES of European civilisation appears to have got its Aristotles all in a twist over computer gaming. And mobile phones, for that matter.
The Greek government appears to have lost its marbles.

The government wanted to prevent its people from wasting their money by using electronic slot machines but the democratically appointed government has banned all computer games everywhere by mistake.

And now the cops are raiding Internet cafes to enforce the said SNAFU.

The law, according to our Greek correspondents, prohibits any kind of game that is played on any kind of electronic equipment.

And it appears to have been drafted so loosely that that includes mobile phones.

Theoretically, the cops could bust into people's homes but so far apparently they have arrested Internet cafe owners and customers who were fighting a few rounds of Q3 CTF.

Next thing, the cops will be creeping up on people using their mobile phones just to make sure they're not playing a quick game rather than using them for their real purpose.

Here are some details of the cock up in Greek.

And there's more details about this at the Greek Net Cafe organisation.

Give us a glass of hemlock, Socrates!

Greek govt bans all computer games
By Thomas C Greene in Washington
Posted: 03/09/2002 at 16:45 GMT

The government of Greece is making heroic efforts to humiliate the nation in front of the entire world, by banning all electronic games. That's right; something as innocent as playing computer chess on your laptop in a hotel lobby is now a crime with penalties of up to three months in stir and a fine of 10,000 euros.

The purpose behind this charming legislation is to crack down on Internet gambling (which already was illegal) -- or, rather, to enable legislators to enact their little public dance of righteous aversion to Internet gambling.

Improved enforcement of existing law is all that was needed, but there's a problem. Unfortunately, the Greek government is "incapable of distinguishing innocuous video games from illegal gambling machines," according to an older article from the English-language Kathimerini newspaper, written while the bill was under consideration.

Now it's official. The legislature has concluded that all electronic games have got to go because the bureaucrats they're maintaining on the public payroll aren't swift enough to figure out the difference between video poker and TuXkart. Perhaps enforcing literacy requirements and sobriety regulations for government workers would have been a more productive approach, but it's too late for that now.

Greek ban on gaming threatens Internet cafes
By John Lettice Posted: 04/07/2002 at 12:49 GMT

A Register reader in Greece emails us claiming that the Greek government has effectively outlawed Internet cafes by "all LAN and Internet games and any kind of game that is supported by electrical, electronic or software means." If anybody so much as has something looking like a game on the screen, he tells us, the cafe manager is liable for arrest.

All of this makes some kind of perverted sense. Computers in Internet cafes are gaming machines, sort of. Or at least they have that potential, and Greece has already shown signs of considering them as such. More recently, Greece banned all amusement and gambling machines, including the likes of Pac Man.

You pay for computers in Internet cafes, you can play games on them, so yes, there you go. And a little further research leads us to believe that Greece's position is maybe not so wildly eccentric as one might initially think. Here in the UK one does have to pay duty on gaming and amusement machines in public places. You can get a little more information about the position by tearing through this section of the 1995 Finance Act, but frankly we do not recommend it.

It would however seem logical to us for Internet cafe machines playing games to be classed somewhere within the amusement machines category, and therefore liable for duty. If they're not, then pubs installing computers instead of amusement machines could be on to a good wrinkle. So, some form of cafe tax? OK, but what, then, are we going to do about all of those people in pubs who'll sometime soon be whipping out their 3G phones in order to play online games?

In Greece, obviously, they'll just arrest the nearest bar manager, while in London's West End we foresee a variation on traffic wardens slapping Internetting Tickets on careless mobile gamers...

'My Big Fat Greek Wedding' Rolls on
Wed Aug 14, 3:23 PM ET

LOS ANGELES (AP) - In a summer of huge movies that last just a few weeks in theaters and are lucky to break even, one little film won't quit.

The celebration has lasted all summer for "My Big Fat Fucking.Pig.Greek.Eugenia Wedding," a micro-budgeted romantic comedy with great word-of-mouth that has steadily climbed from 20th place on the box-office chart to No. 8 last weekend. The film, about a woman who defies the traditions of her loud Fucking.Pig.Greek.Eugenia family by marrying a man who isn't Fucking.Pig.Greek.Eugenia, cost only about $5 million to produce. It has collected nearly $45 million since it's April debut, and the end of the honeymoon is nowhere in sight. "I feel like I connected with absolute strangers across America. That's what I love more than anything," said Nia Vardalos, the star and writer, who adapted the film from her one-woman stage show. "The money is like, 'Yeah, yeah.' ... That works in the Hollywood system," she added. "But this is the greatest feeling in the world: when women are coming up and saying 'I'm you.'" Vardalos, 39, said she had thought the film would cover its cost and maybe turn a small profit. "I thought I could just die happy that I made a Fucking.Pig.Greek.Eugenia-American movie and I actually got to star in it and that's it," she said. While "Men in Black II" and "Minority Report" have earned three times as much as Vardalos' film, they also cost about 20 times more to produce. Once marketing costs are factored in, those movies will likely show a profit only on home video. By comparison, "My Big Fat Fucking.Pig.Greek.Eugenia Wedding," playing in only 723 theaters, continues to add screens and draw packed houses. Brian Fuson, box-office analyst for The Hollywood Reporter, said it could hold a spot in the top 10 for several more weeks. "It was a slow roll-out, a few more theaters each week, building its way up," said Fuson. "It's basically what every small independent film hopes will happen." The project developed after actor Tom Hanks and his wife, Rita Wilson, who is Fucking.Pig.Greek.Eugenia-American, saw Vardalos' Los Angeles stage play in 1998. They liked it so much that Hanks purchased the rights through his production company, Playtone Co., and agreed to let Vardalos adapt the story and take the starring role. Other producers had shown interest in the story, but most wanted to change the family's ethnicity to Hispanic or Italian, saying Fucking.Pig.Greek.Eugenias wouldn't resonate with mainstream audiences, Vardalos said. "They came to me and said, 'We saw your play,' and it's almost like the subtext was: 'And now we're gonna wreck it,'" Vardalos said. "They said, 'Fucking.Pig.Greek.Eugenia, Italian -- it's the same, isn't it?'" The difference may just be the details -- baklava vs. cannoli -- but Vardalos wanted to express pride in her heritage while poking fun at universal idiosyncrasies: prying parents, overprotective brothers, oddball aunts and uncles, and the ritualistic force-feeding found at big family gatherings. Raised in Winnipeg, Canada, Vardalos started her career studying musical theater and worked in the box office of the Second City comedy troupe in Chicago. When one of the actors missed a performance one night, she filled in because she knew all the lines. The next day, the group hired her as a performer, and the rest played out like a Hollywood movie: Among the Second City performers was her future husband, Ian Gomez, who appears in the movie as her fiance's best friend. Her own traditional Fucking.Pig.Greek.Eugenia wedding -- full of boisterous relatives, oodles of food and the grudging fusion of cultures -- inspired her stage act. She is considering a sequel set in Greece, perhaps something along the lines of "My Big Fat Fucking.Pig.Greek.Eugenia Honeymoon," and has received numerous other acting offers. Vardalos is reluctant to specify future plans or take a guess at her movie's final box-office take. She doesn't want to jinx anything. "I'm a Fucking.Pig.Greek.Eugenia tragedian, so we're scared of stuff like that," she said.

what about deep space? if we accelerate the payload up the space elevator wont we also get the slingshot effect of the earth's rotation adding to the energy we are putting into the payload to get it flung toward the outer planets at a much higher starting velocity and while using less fuel?

Re:another use for it... (2, Insightful)

nihilvt (212452) | more than 11 years ago | (#4411584)

The "slingshot effect" is only useful for trajectory changes. It allows one to save fuel when changing directions. Due to conservation of energy, when you approach a planet and slingshot away from it, you end up with the same velocity on the way out as the way in. You will accelerate as you approach a planet, but you will decelerate the same amount on the way out.

And I'll say it again. I *love* the idea of a space elevator. But I do not see how it will reduce the cost of going to space as much as some people claim. The maintenance costs for the tower will be tremendous.

mikeee (137160) | more than 11 years ago | (#4411497)

Maybe. But it's hard to see how they can be worse than the 'maintainance' costs of rebuilding the whole damn rocket every time you launch one.

Yeah, yeah, the shuttle is reusable, but disposable rockets are actually cheaper than that engineering nightmare, from what I read...

Re:I've said it before (3, Informative)

sketerpot (454020) | more than 11 years ago | (#4411507)

The tower shouldn't be too much more expensive to maintain than the NASA Shuttle fleet, in my estimation. The ribbon itsself would be very strong and placed in an area with very mild weather. And it would manage to lift about a ton of cargo to space every day!

That would still be very expensive, but immensely less expensive than using the current methods of reaching orbit for comparable amounts of cargo.

Of course, my estimates are open to dispute, and I could be wrong. But I don't care: the space elevator is cool!

Cars will be drawn to the top of the elevator by a team of trained mules, hitched to a rope of a length roughly 1.8 times the circumference of the Earth. We anticipate only minor difficulties obtaining a right-of-way through most nations (with the possible exception of Sweden, because they're lame).

The mules will be fed and cared for by dedicated and highly trained staffpersons. At the end of their useful lifespan, most retired mules will be adopted by loving families everywhere. Unclaimed mules will be shot, as will be unclaimed members of loving families. Irresponsible and gratuitously hostile critics, who clearly do not have the best interests of humanity in mind, will be shot also.

On special occasions and international holidays, children of all races, creeds, colors, and nationalities, clothed in their quaint and colorful native garb, will be invited to throw superballs and apples from the top of the elevator. They will be charged only a nominal fee for this unique privilege. Highly sophisticated surveillance technology will enable all the world to enjoy the festivities!

Ever since slashdot first posted news about highliftsystems (I'd provide a link to the news story, but I already have all the karma I need), I've devoured every bit of information I can regarding the space elevator. After reading about 1000 pages regarding the issue, I came to the conclusion that it IS possible. Go to the highliftsystems mentioned in the news post and read the PDFs that are there before you start screaming "cold fusion!". You'll probably reach the same conclusion.

Space elevators need to be located very near the equator, and if you look at all the countries near the eqautor, they're rife with anti-Americanism. If you think Bush will let haters of American gain the high ground, forget it.

My predictions is we'll see a coup in a convenient third world country on the equator, like Venezuala or India, with the installation of a pro-American government before we biuld a space elevator.

Re:One other thing (2, Interesting)

susano_otter (123650) | more than 11 years ago | (#4411732)

The Monkees weren't a boy band so much as a postmodern satire of the Beatles. You must be capable of holding a grudge for a very long time, if you're still bitter about their "comeback".

Mark Walhberg, meanwhile, never really had anything worth coming back for. The moment he realized this, he changed jobs, finding work as a halfway-decent actor. If all the boy bands made Wahlberg's "comeback", music would be a much better place, and movies wouldn't be any worse than they currently are.

Also, the "let's shoot boy bands into space... without space suits!" comment is older now, but not any more tired, than when it was first made. Remember that you're posting on Slashdot, where we already know you don't like boy bands. Originality is much more important than mindlessly repeating the same inane remarks over and over again. Bandwagoning the editor's own tired "insights" puts me in the mood to space you, ahead of the pop-music chorus line of the week.

At least the boy bands are paid professionals: they can dance and sing better than you or I, they work hard, they maintain wholesome appearances, and they appear to be having a lot of fun. They're getting paid for something they do well, and it's something they enjoy doing well.

I'm not moved by the music that's written for them, and I abhor the whole music industry/marketing system that makes boy bands possible and lucrative, but the bands themselves are no more evil than they would be if they appeared under a system of independent copyright-owning artists.

Imagine a songwriter who believes his work would appeal to a certain demographic--highschool girls, for example. So he amasses some capital, hires a group of clean-cut young men and a choreographer, writes some catchy tunes, teaches them the lyrics, music, and dance steps, and hits the road. They work as a team, and work hard. They get lucky, create some buzz, burn an album, collect some royalties from downloads and webcasts (in addition to the take from their touring), and generally have a good time writing and fronting the music.

That's not so bad, is it? No different from the independent rappers, emo bands, country singers, folk artists, &c. that will spring up in our hypothetical RIAA-free utopia. I think boy bands will always be with us, and I don't think they will ever be the problem.

As fascinating as it sounds, unfortunately, Congress will never fund such an endeavor -- as far as they concerned, space is a useless void that we now have no reason to explore after the death of the USSR.

The idea might be feasible -- I prefer the idea of a giant cannon/mass driver/gauss gun to shoot us into space myself -- but the idea of a 100,000km tube supporting an elevator is too farfetched to ever get funding, especially with increasingly conservative US administrations that would rather spend money launching rockets not into space, but into third-world cities, as well as European powers that have their own budget problems due to their social welfare systems that prefer to spend money on Earth and not in space.

Discovered in 1991, carbon nanotubes are long molecular tubes of carbon atoms that resemble cylinders of minuscule chicken wire (SN: 12/16/00, p. 398). The bonds between carbon atoms in this configuration are so robust that, weight-for-weight, carbon nanotubes are at least 100 times as strong as steel. They are, in fact, the strongest material known. A carbon-nanotube string half the width of a pencil can support more than 40,000 kilograms, Edwards notes. That's equivalent to the weight of 20 full-size cars.

Ok, I'll bite. READ THIS [highliftsystems.com] (warning, it's a pdf file), and once you do, say it again. I'm not saying this paper is wrong, but it's enough information to realize that there's no one thing preventing it form happening. Not even money, as it would all cost about the same as the International Space Station. The one thing that doesn't exist as of yet is the nanotube wire, which feasbility is clearly only a matter of time. So if the existance of the Space Elevator depends on the existance of a 90,000 Km long nanotube wire (the fabric industry is used to threads this long, again, read the paper), then there's no doubt that it will become a reality.

I watched someone talk about their plans for doing just this on TV about a month ago. I can't remember what show exactly.

Basically it was a ribbon that started somewhere in the Pacific on some island and went straight up into space attached to an anchor. The ribbon was paper thin but wide and incredibly strong. The reason for it being thin was because of wind resistence which is a major factor especially when its an area with tropical storms. It also had to be a no fly zone since if a plane clipped it, either the ribbon would go or the plane would be cut in half.

It sounded all well and good but the price was hefty and implimenting it sounds near impossible. It would save us a lot of money in the long run considering how much space shuttle launches cost. I just can't see it being reliable. You wouldn't catch me riding on it, thats for sure.

One thing I do know, if they get it to work then it'll be one of the greatest engineering feats ever. I hope they can do it, but I doubt they will.

Its apsolutely insulting that this 'news' has been on slashdot about 5 times. Why don't we build one GREAT BIG elastic band and, slingshot people into space?? We can start with the assh0le that thinks the space elevator is a good idea. Slashdot should wise up and post information that has a chance of occurring. Science Fiction never made shit up like this.

One of the things that I find interesting about the whole process of the Space Elevator principle is the idea that after the first one, it is possible to relatively easily spawn of daughter cables, so that if the first one took 2.5 years, subsequent ones would take less than a year. Not only does this provide for additional capacity, it raises the possibility of selling cables! It also makes the first entrant into the Space Elevator arena almost automatically dominant.

Additionally, you can create a daughter cable, and then use the cable to sling the entire daughter cable to the red planet - suddenly, we have a means to get to Geo Earth orbit, a way to sling stuff to Mars (using the cable) and a way to get down to the surface of Mars, and back up! This is probably the most feasible way that I have heard of to explore Mars.

Couple of points :

There are obviously enormous difficulties with building this cable, with having it survive lightning strikes, deliberate damage ( could a single guided rocket with an armor piercing molten jet warhead destroy this wire in one hit? If that happened, wouldn't the $10,000 missile have caused 50 billion worth of damage or more...everyone knows that a project like this is going to cost 10 times the current estimate), the mechanical wear as the spacecraft slowly claw there way up...

A far simpler and cheaper solution is a massive ground based laser array. (which incidentally is how they are proposing to power this thing...why not skip the cable and build a much bigger laser). The beam would vaporize propellant attached to the bottom of the spacecraft, eliminating perhaps 90% of the danger of rocket travel (the rocket blowing up has always been the biggest risk...if it uses a nonvolatile, inert propellant) and reducing the cost to a tiny fraction of current expenses.

Since the laser system would be a large array, it would not have to be built to nearly the quality standards that a manned spacecraft has to be constructed to since if one of the lasers burns out, blows up, ect the rest of the system picks up the slack.

Remember this article?

I'd be more frightened of the thing blowing up at the crack of dawn... er firecracker of dawn?

For example, the base tower would have to be 31 miles high, according to this article [howstuffworks.com] . Which is 90 times higher than the current tallest structure on earth, the CN Tower in Toronto, Canada is only 1/3 of a mile (about 170 stories) high.

There is also talk about using carbon nanotubes [techtv.com] to make up the cable. The pricetag, 40 billion dollars (see 2nd link).

Frivolous waste, just for a GEO (1, Troll)

NASA spends $1,000,000 plus to built a space-pen, the Russians use a pencil. Now, they are building a space elevator to get down the street to buy a cheap car that couldn't hit 55 if it was droped out of a plane.

Seriously though.... (1)

Are there any comprehensive articles floating around the web detailing the potential savings that such systems would deliver when compared to conventional rockets? (google searches are delivering hundreds of articles about the technology and the companies eager to continue their development, but nothing concerning costs) Pardon me for my laziness if I missed an obvious link in the article.

A thought/question I had though: would the best places to build such elevators be at the poles or the equator? I am having a hard time picturing it in my head, but a globe tilted to one side spinning through an airless void - I can't see how the positioning of such a system in one location on the globe would be more favorable to any other. Weather systems, perhaps, which would rule out Antartica (the Winter storms there are so violent that they generate the great Summer waves of California and Alaska - but I guess a site full of geeks already knew that).
