Space Elevator Prizes Proposed 214

Posted by michael from the up-up-and-away dept.
colonist writes "Space elevator proponents are planning competitions for space elevator technologies, similar to the Ansari X Prize. Elevator:2010 will organize annual competitions for climbers, ribbons and power-beaming systems. In other space elevator news, researcher Bradley C. Edwards recently left the Institute for Scientific Research to work at two companies on materials and technology. Also, the space elevator has caught the interest of Google's founders: 'At a space camp in Alabama last year, Brin talked about creating a space elevator to transport cargo up a special tether attached to earth. Also last year, Brin joined Page in proclaiming they should found a nanotech lab at Google.'"

    No link to pursue, but one feels that if it's at Google that would be more like a discussion forum than a lab. Unless, of course, they are proposing that Google starts funding a research center. If they follow, for instance, IBM's and ATT's footsteps, that would be a Great Thing(TM).

      Seriously, these guys must be developing some sort of messiah complex if they think space elevators and nanotech have anything to do with their core skills. I met Brin in 2000 and he was getting full of himself then. The last few years of success and money must have convinced these two they're invincible and that any field could benefit from their presence. It's the same "I'm rich because I'm the smartest" attitude that too-young Wall Street traders get after they get rich at the first thing they try.

      The real test if Google is any different from any other flash-in-the-pan will be when they hit some real adversity. Until then, they're just the latest Lycos/Altavista/Inktomi fair-haired boy to make a splash with VC funding and a slightly better idea. The truth is, no search engine has substantially improved once it's been deployed on a large scale. If no one's passed Google on quality, it's mainly because they were the last to get funded before the crash.

    From a link from the FA link: [nasa.gov]
    In 1895 a Russian scientist named Konstantin Tsiolkovsky looked at the Eiffel Tower in Paris and thought about such a tower. He wanted to put a "celestial castle" at the end of a spindle shaped cable, with the "castle" orbiting the earth in a geosynchronous orbit (i.e. the castle would remain over the same spot on the earth). The tower would be built from the ground to an altitude of 35,800 kilometers. It would be similar to the fabled beanstalk in the children's story "Jack and the Beanstalk," except that on Tsiolkovsky's tower an elevator would ride up the cable to the "castle".
    Depending on how it was written, wouldn't this cover at least part of Arthur C. Clarke's idea (and patent) for using geostationary orbits? To fully cover it, the castle would have needed radios, but Marconi hadn't stolen the radio yet... Did it have semaphores?

    Such prize awards might have a wonderful side-effect.

    Hans Moravec's Rotovator(tm) [google.com] picks up hypersonic (near mach 12) payloads from an altitude of 100km and slings them to orbit.

    Current proposals for implementation of the Moravec's design [tethers.com] rely on a hypersonic air-breather of advanced aerodynamic design like the Boeing DF-9 (that exists only on paper).

    Is there anything likely come along in the near future that could take paylods to 100km and mach 12?

    Probably the same thing that is driving the bureaucrats to make all this noise about space elevators now:

    The prospect that centralized space programs will be left behind by the emergence of a competitive suborbital launch industry with the emergence of suborbital space tourism and prizes like the Ansari X-Prize.

    A key to the Rotovator(tm) is getting hub mass in place to keep it out of the atmosphere while it picks up mass from 100km@mach12 -- but that mass can be any old space junk (what is the dry weight of the International Space Station?) -- at least at the hub where it counts the most for high strength materials like carbon nanotubes. However, you can do a Rotovator(tm) with off-the-shelf commercially available fibers and still have a factor of 2.

    Nice thing about Rotovators(tm) is that they can be built with much lower capitaliztion over a much shorter period of time using existing commercial materials. All you need is a bunch of mass orbiting near earth, some quite-doable tethers, and sufficient manuverability and speed in the atmospheric leg to hook up with the tether as it reaches the nadir.

    Modest prize awards toward early milestones of a space elevator could end up enabling the Rotovator(tm) as well.

    The Ansari X-prize seeks to reproduce an effort that had already succeeded, and been substantially surpassed, by several governments.

    A "space elevator", on the other hand, is totally unlike anything ever done before. As I read in a Slashdot post some years ago (referring to nanotubes, the favorite among space-elevator aficionados), "When somebody has built a 40,000 millimeter bridge across a creek on campus, then we can start to talk about a 40,000 kilometer bridge straight up".

    The fact that we have not yet achieved one millionth of the task (and in fact fall several orders of magnitude for that) suggests to me that, much as I would love to see a space elevator in place, the job today belongs to materials scientists who are looking at shorter-term goals.

    An eye to the future is great, but experimenting on climbers is like practicing the high jump: if you're jumping twice as high today as last year, I wouldn't start drawing any exponential curves. The ribbon is the really, really hard part, and we're currently so far away from it that research energy is better spent elsewhere for a while. 2010 is way, way too close.

    Maybe with enough motivation we could get that 40,000 mm bridge by 2010, but somehow I doubt you're going to raise $10 million to build a bridge. The X-prize shot somebody into space for that kind of money.

    I'm prepared to be wrong. I'm a software developer, and I've learned that as a consultant I can say, "Your project is doomed" with 95% accuracy before I've even heard your name. Being a nay-sayer is easy. But the real trick is being able to spot the 5% that will actually be profitable, and there are a lot of projects more immediately deserving of this kind of money.

    for example, say i wanted to lift a 100kg man up to 380 km (ISS height). This would put a force of 1000N(the man) + 380km *area * density (of cable).area of say 30 cm^2 gives a force of 1000 +1140* density. failure is usually measured in stress (force per area) soooo lets see.....

    with
    material/stress/density steel 250Mpa 7850 kg/m^3 nanotubes 63GPa 3520kg/m^3 calculated stress steel = 2.9Gpa calculated nanotubes = 1.3 GPa

    SO nanotubes may handle the stress, but noone can make 380 km of nanotube rope yet. Even that much kevlar would be tough. and this is without incorporating the added stress of accelerating the man (starting his trip up the rope).

    In short, new materials are needed!

  • Sergey Brin speaks publicly about space elevators. David Brin (science fiction author) speaks publicly about space elevators too. Does anyone know if these two fellows are related? It just seems too coincidental to me.

    Remember, you are special, just like everyone else.
    • I have wondered that myself, but I think it is just a coincidence - Sergey was born in Moscow, and his family emigrated to the US in 1979 according to this [go.com]. David was born in the US in 1950. Still could be distantish relations, but if you google (what else?) on "david brin" and "sergey brin" then you only find 4 pages of hits with both names, all of which seem to be coincidental. So if there is a relation, they are keeping it well hidden!

    I think the idea of building a space elevator the instant we can is fundamentally flawed.

    A space elevator would be an insanely profitable project, one that has tremendous implications for things like power generation, communications, space exploration, tourism, and precision manufacturing.

    No doubt about any of those things.

    But, before we go building a space elevator, wouldn't it be a good idea to give it a few thorough evaluations here dirtside?

    There are countless questions that people are going to want to ask - is it strong enough? What if it breaks? Are C-tubes durable enough? Will it conduct electricity and "short out" the ionosphere? What about storms? What about terrorists? Do C-tubes wear out?

    The first, best use of C-tubes would be a good bridge. If you had a suspension bridge built with pencil-thick C-tubes, people would get used to the idea that something to small would be so strong.

    I figure the best place would be to build a suspension bridge over the straight of Gibraltar. Can you imagine how beautiful and spider-web like such a bridge would/could be?

    That would provide major economic boon to North Africa, provide cheap tourism for Europeans, and provide an excellent proof of the viability of C-tubes as a building tool all in one.

  • Or else we're finished would have to be some kind of a geostationary site that collects energy from the sun directly.

    The reason why I surmise this is based on a few reflections I made about modern society and what we're doing. Here are a few starting points (certainly not the defining factors of what makes our present society tick):

    1. Since 1900 our civilization has grown almost completely dependant on fossil fuels

    2. These fossil fuels are not replaceable and the current "replacements" for these fuels cannot
