Carbon Nanotubes

[GSG1298]

00:24 "About a centimetre (About half an inch)". Seems so unjust when talking about carbon nanotubes!!

Take that Diamond!

[Virusly]

0:12 thumbs up if you have to watch that part twice to get it

[NicolasMichael1]

@Virusly can't say i needed to watch it twice to understand it

[ZanyRocket]

There is a competition every year to build the strongest nanotube tethers. If the winner gets a strength/mass ratio of over 20GPa (I think), they win $2,000,000 from NASA, because tethers of this strength can be used to make space elevators. No one has yet succeeded, but strengths much higher than this have been observed for small samples (5 grams is required for the competition). The theoretical limit is 200GPa - definitely enough for orbital elevators. These are exciting times we live in.

[maxchowla]

good video

[Spiritboymark]

Umm... I think it's wrong... "nano" means "dwarf/small".... thus getting it's name..

but it's sure a billionth of a meter

[HORRORTV1]

MAXIMUM DEFENCE

[REAPER3382]

Just one step closer to become joker or prophet or aztech or nomad. Or god forbid that mute mutherfucker alkatraz.

[Spiritboymark]

MAXIMUM ARMOR!!

[asianmacker]

Could this be used in automobile applications?

[meatisdeliciouse]

what is the strongest natural substance? How much stronger is a nano tube than steele? How much stronger is it than a diamond?

[roetemeteor]

@meatisdeliciouse

Around the same strength if it's low quality.

Read what the material is. CARBON nanotubes.

Diamond is essentially carbon arranged in a certain way and treated via tons of pressure and heat.

Even though this is somewhat inaccurate, Nanotubes are a shortcut of that, but it's complicated to explain.

[meatisdeliciouse]

@roetemeteor Finally, a message that WASENT abusive or rude. 

[PinkProgram]

Has anyone tried braiding nanotubes and then coiling the braids around a nanotube core to mimic the structure of wood fibers except with a pure carbon aggragate... a springy super-diamond? I'm trying to find a material for my prosthetic skeleton. It seems rhenium diboride isn't suitable.

[hazonku]

@PinkProgram Yes, they've figured out how to spin carbon nano tubes into yarn.

[quangluu96]

1cm LOL dang, so how are we guna make 250,000 miles for space elevator

[dandvd]

@quangluu96 You are wrong by an order of magnitude. The other end of the space elevator needs only be 24,000 miles away from Earth.

[sinshiro]

@dandvd besides a space elevator made our of nanotubes would completely burn out our atmosphere....

[leo1300177]

Nano = Billionth not billion!

[quangluu96]

@leo1300177 i know people got mistaken alot, billionth mean 1/1,000,000,000 and BILLION is 1,000,000,000/1

[quangluu96]

This thing is transparent- CLOAK ENGAGE!

[paul486]

who reckens we will have a space elevator with the stem made out of carbon nanotubes

[crazygeek777]

now nanotubes are produced in the feet

[DPat6590]

@crazygeek777 Wait, what exactly do you mean in the feet, like they put them in the feet or what?

[crazygeek777]

a foot is a measurment used in the united states... for some reason

[paranoid492]

MAXIMUM STRENGTH

[quangluu96]

@paranoid492 LOLz and maximum speed

[quangluu96]

@paranoid492 LOL also our future NANOSUIT =))

[kriskillerX]

@paranoid492 MAXIMUM OWNAGE

[Planbskate230]

I'm going to laugh when a huge lock cutter breaks when trying to cut something one thousandth the diameter of a piece of hair.

[REZOFFICIAL]

LMAO! That's quiet an imagination you got there, very good laugh!!!!

[Etrician55]

something strong and extremely tiny is not a good combination for our lungs, look at asbestos... long, lightweight and stronger then steel, they imbed themselves in your lungs and can cause permanent damage, this may very well be the next asbestos, because its starting just how asbestos did, construct now, test later when people are getting sick

[vgta88]

no he has a point, i hate asbestos. its a good concern. More research needs to be done. They should do more stem cell research so I can replace my lungs.

[okkima]

I want electric car made from nanotubes :D

The big next step from carbon fiber.

[Ryangdotexe]

I can't wait until they find a way to manufacture graphene sheets. I want a computer that uses graphenes conductivity in it's circuit boards.

[pgtv69]

why can they only be 1cm long??

how long can a corbon sheet be made??

[melistanbul]

I am not an expert in this subject, but I guess it's because of the synthesis process. We cannot really control the synthesis process, the growth process of the carbon nanotubes is not totally discovered. The tubes occur on its own, then we just purify and measure them .

[allgoo19]

pgtv69:

Remeber, this video was posted in 2007.

I have heard about nanotubes which can be grown in length, which means it's always pure and doesn't need to be purified. The length can be in feet.

Another story I have heard about is nanotube sheet(or graphene) in size 4 ft, x 6ft. or something close.

If you subscribed to google alert, you get all the latest information.

Some of the information may not be reliable, though.

[meloveanna]

they are long as hell now

[f38stingray]

I don't know how big they can be made now, but a nanotube is essentially one very long monoatomic molecule. Molecules very rarely get this big, no matter what they are made of.

However, the fact that it is just one molecule is what makes it that much harder to destroy.

[pandapowerjamie]

if its stonger than steel then why arent they using it on everything or basically replacing steel?, or are they worried of the enviromental effects?

[irbaileyus]

Thats a well thought out considered response, you should take your suggestion to a researcher or maybe just do it yourself and get really rich.

[mroddy2]

the cost of making nanotubes is much greater than the cost of steel and other metals. As the technology gets better the cost will go down but that will take a long time

[DevoiranGamer]

Also, as it starts, they have only been able to manufacture lengths of one centimeter, or 2/5 of an inch.

And you can't bond them together, yet.

[mshaw88]

they say nanotubes are stronger than steel but thats only in axial tension, they suck in compression and bending

[DPat6590]

@mshaw88 Wait, axial tension what is that exactly? Being pulled apart? So like, nano tubes would not be good armor or somethin for like a tank? I heard the military is researching with nano tech. now.

[allgoo19]

None of us today will live to see the full potential of this material.

[pavlovcik]

Not the fullest, but soon we will see many more products!

[n1bigdaddy]

yes we will

with nanotechnology aging can be halted

probably within 3 decades

[Ryebreads]

Probably not ever.

[jmario232]

@n1bigdaddy

Agreed.

[easilydiappointed]

nice work
