My dad told me that if you put nanotubes on somthing it can grow very fast is that true?
mars 9th, 2010 at 23:30
Could this be used for a hull of a space ships
mars 11th, 2010 at 21:19
I have heard that if they ever build a space elevator this is the stuff they will us to construct it but how would in be constructed in such a great quantity?
mars 20th, 2010 at 15:02
Sweet. To quote The Discovery Channel… “The World Is Just Awesome…” Such endeavors give me some much needed hope and optimism…

@DPat6590 , indeed, the nanotubes we show in this video are Carbon Nanotubes. We grow them on a regular basis for our research.
april 16th, 2010 at 7:41
@moniker127, Yup, that is correct. We use nanotubes in nano- to micro-sized semiconductor applications. This includes wires as well as transistors.
april 16th, 2010 at 7:43
@Bestdogsintheworld, Perhaps it could. I will not officially speculate on the possibility of that, however, I have heard that some people are making ships with carbon nanotubes and carbon composites. These are ships that sail in the ocean, not in space, though.
april 16th, 2010 at 7:45
@lloydyz1150. As I mentioned to a previous commentor, I can’t really speculate on whether this is a suitable material for a space elevator. However, I have heard much talk about this being a good potential. Now, to make carbon nanotubes in large enough quantities for such an application (as you mentioned), I think that will indeed be a big challenge! (but something very do-able if people are motivated enough)

@skimmy6, As of now, I can’t say I know anything about that…

@Christian9872
Well, as you state with your last sentence about money, I must disagree. Even if capitalism isn’t a great thing for many people, in the R&D field, it induces competition amongst companies which would therefore induce faster production.
However, if humans were able to work optimally, in somewhat of a communistic environment, then of course faster progress would be made by working in collaboration. This is impossible at the moment given the diverse morality nature of humans.
april 20th, 2010 at 5:43
@Christian9872 very true, but, people need boundaries. Without boundaries people would go mad. They would kill, steal, etc. Money is what keeps humanity sane, even if that is what keeps us from advancing in some fields.

So they can basically build food from atoms…
april 29th, 2010 at 7:42
Any info on CNT’s being used for paper batteries/super capacitors? Back in December I read about professors at Berkeley having a break through with carbon nanotubes on normal copier paper!?
april 29th, 2010 at 18:27
but they dont say that so much power will be wasted!
maj 1st, 2010 at 21:23
Theres on-going research going on about how to manufacture carbon nanotubes in excess. Im looking for resources of any kind to help assist in this research. Do you know any new manufacturing processing or state of the art equipment that has a promising future in this research?
maj 6th, 2010 at 9:58
@Christian9872
I think if people didn’t worry about money, they would have to make their own food, and wouldn’t have time to research things like this.
maj 8th, 2010 at 6:01
which is harder; carbon nanotubes or aggrogated diamond nanorods?
maj 14th, 2010 at 6:58
@Christian9872 Hey thos was some good questions! They would be awsome for the military! I think they already have a Full body suit, they can make u super strong and Fast! ijust for get the name its Called! …

@skimmy6
Unlikely. May bey you can somehow replace bone-tissue, but your metabolism, proteome and many other physiological aspects that are supposed to happen gradely throughout maturing., will stay behind, which will do much damage to your body. Growing is more then gaining length alone, you also need to alter muscles, tendons, sensory organs, metabolism, blood flow, etc etc
maj 22nd, 2010 at 22:10
Thank for the video. It was very educational.
I hope you will post more videos in the future.

@laitela01, I think that may be quite a leap from what we are proposing here. But nanotechnology does take us a step closer towards controlling materials at the nano / atomic level.
maj 23rd, 2010 at 0:09
@jpc1105 , Yes, there has been a lot of interest in carbon nanotube applications in batteries. Some have demonstrated flexible batteries using “paper” coated with carbon nanotubes to serve as the electrodes. If you are interested in technical papers on this, may I suggest searching for “carbon nanotube battery” in google scholar. Quite a lot turns up!

@rroge5 Using carbon nanotubes to make digital logic circuits will save power! Imagine a laptop or a LCD monitor that doesn’t heat up. CNT circuits can be more power efficient, and thus require less power to do the same job.
maj 23rd, 2010 at 0:14
@deanominatorx Many existing companies already do this. Of course, it depends on what kind of nanotubes you want – multi-walled or single-walled? long or short? …etc. One group of researchers at Rice Univeristy is researching how to manufacture CNTs into “threads”, and this work was recently featured in the May/June issue of MIT’s Technology Review.

@OmnibusWhiteLion I can’t say I know much about diamond nanorods…so I’m afraid I can’t answer this…
