. . . and unlike iss, Bigalow can do materials experiments.

yea, but that wouldn't exactly be good for the environment(at least for humans).

#54 Re: Interplanetary transportation » one reason nuclear propulsion may be ok'd » 2006-07-12 23:30:58

because all the other fuels will be dried up . . . nuclear might be so common place that nuclear rockets may make more sence in a generation(human) or two.

He got it up there didn't he? I think the important point is he makes space stations cheaper and maybe even interplanetary spacecraft. Cheap rockets are of course still a problem . . . .

I'm sure they'll learn both limitations and new tricks while they're up there!(not people; not yet, but soon enough I think!)

"Today, non-experts can design and create shapes in at least two molecular systems: DNA--which can be "stapled" together according to very simple procedures--and Christian Schafmeister's polymers, which take a rigid form without even needing to fold. But building these molecules takes significant time, because they are still built using large tools that take a relatively long time to do each step. Molecule-scale manufacturing tools (Ned Seeman's polymer builder is a step in the right direction) should eventually speed up the process thousands or millions of times per molecule, as well as parallelizing it."

. . . and nobody criticizes the bible, or, the bible is socially/politically uncriticizable - amazing.

#60 Re: Science, Technology, and Astronomy » meteorite strike? » 2006-06-10 11:14:19

well, the news has spread to this website, but, it is still not confirmed; although, the article did give a new detail about a mountainside getting hit; probably, it's just taking time to get out in the wilderness to see the extent of what happened. This news item will surelly spread bigger and bigger as the news spreads from word of mouth.

#61 Re: Science, Technology, and Astronomy » meteorite strike? » 2006-06-09 23:31:12

has humanity become numb to science and nature?

instead of the inefficient billions of atom nano-assemblers positioning and binding individual atoms, we have a kind of mechanically directed self-assembly!

usually, when a theoretical crisis like this is presented, an innovative solution is found which speeds the whole development;

#65 Re: Interplanetary transportation » Space Elevator news » 2006-05-13 21:38:55

well, 97 percent increase in nanotube purity got to put a pretty good dent in the materials problem for space elevators.


As for the statistical calculation that space elevators will be impossible to build, I just saw a spacedaily article about genetic algorithms being used on nuclear propulsion; certainly, advanced computing can be used on controlling the making of the space elevator ribon; if it turns out to need that much computing, what a technological marvel the space elevator will turn out to be!(yes, i view technologies as precious and the more marvelous the better!  I have my own rationality about it all, but it seems to be all my own!)

#66 Re: Interplanetary transportation » Space Elevator news » 2006-05-12 21:34:19

i'm affraid I don't know all the latest results on nanotubes well enough to exactly say where they are in making bulk nanotube materials, even if I put in 'nanotube alignment' or something like that in yahoo or google; i'd say ask Liftport!  They probably monitor the state of the art much more closelly than I there.

But!  As I've mentioned, I remember seeing video of some kind of nanotube sheet maker that spat out about two or three meters of plastic sheet looking nanotube material in a few minutes time(this seems almost years ago now), so, they have the nanotube alignment problem down to some pretty good degree.

I'd post this here because it is a way of getting us out into space, even as a sort of interplanetary propulsion.

I saw this article

http://www.yomiuri.co.jp/dy/features/sc … Y02006.htm

an article about some more nanotube work that increased nantube purity by like 97 percent!  And!  They can already roll out nanotube sheets meters long, so, I decided to go look for some of the latest news on space elevators; the link given shows some pretty good stuff including an entertaining countdown meter!

#68 Re: Human missions » Alt.space debacle (GCNRevenger 's gonna love this) » 2006-05-05 11:31:20

wow, did I say the earth is round?  That space and time are flexible?

#69 Re: Human missions » Alt.space debacle (GCNRevenger 's gonna love this) » 2006-05-04 10:01:31

maybe I was right all along, we need to make a scientific culture - bare minimum, a science cultured corporation, if not a whole country; this is the only way to get space colonization funded.

#70 Re: Interplanetary transportation » New anti-matter engine ideas, » 2006-04-17 21:36:47

which link did you want?

http://www.google.com/search?hl=en&q=an … gle+Search

well, I've made the same mistake a couple of times myself(not looking things up I could have myself).  So, take care!

#72 Re: Interplanetary transportation » New anti-matter engine ideas, » 2006-04-17 17:03:18

i've recalled that what I knew about 80's anti-matter containers was not that they had just learned how to contain anti-matter, but they had just made and contained anti-hydrogen, so, physicists ability to contain antimatter was at a fairly high level even back then.

#73 Re: Interplanetary transportation » New anti-matter engine ideas, » 2006-04-17 14:29:21

it's been awhile, so, I can't generate a reference link immediatelly, but I remember some recent news about scooping up anti-matter from the earth's own radiation belts; apparently, there is enough to scoop up!

250 million just to make and store the anti-matter; they've had anti-matter storage since the eighties at least, so they can't be too bad considering the pace of development in the particle physics industries; i guess all that basic research can really pay off!

#75 Re: Human missions » Gcnr, i have private space colonization cracked! » 2006-04-17 11:47:31

I'd like to say that I did not see or read any previous discussion with avenger about private space colonization.
