[@MrHansiping]

For those who got to the end and had no inkling what he's actually doing: The challenge is very hard: You have a bunch of carbon nanotubes that you want to make into a computer circuit, you want to get them to sit down on a silicon wafer in a way that allows you to make billion-element circuits with switch sizes smaller than today's smallest transistors. How do you do this? The solution, in principle, is actually very simple. You suspend a bunch of individual carbon nanotubes in solution. Then you make very fine patterns of things that stick nanotubes and don't stick nanotubes down on your silicon wafer. Then you just wash the nanotubes over the silicon wafer until they stick in the right place. Well, in detail this is actually really really hard to achieve: First, you need a way of generating patterns that are denser than those achievable by modern lithography. People have come up with very clever ways of doing this. Two of the best ways are something called block-copolymer lithography and DNA nanotechnology. In either case what you are doing is making chemical polymers that self-assemble together to create very fine patterns. Second, you need a way of purifying semiconducting carbon nanotubes, cutting them to the exact right length for your circuits, then suspending them in solution. This is actually also no an easy problem, but people have come up with ways of making small polymers (eg, short strands of DNA) that bind onto carbon nanotubes, wrap around them, and suspend them in water. Third, you need to create just the right interaction between the patterns on the surface and nanotubes in suspension for them to land on the right spots and wiggle into place along the patterns you define. This is pretty hard. You need to engineer the right chemical handles onto both the surface and the polymers wrapping the nanotubes. You might have to have the surface help channel stuff into the right place with morphological features. Then you create just the right conditions so that nanotubes will align themselves onto surface patterns via many weak chemical interactions (if the interactions are too strong they can lay down in the wrong directions, make tangled messes, etc). This is pretty hard. People are still figuring this out. Lastly, you need to scale up all of these processes so that IBM or Intel can make perfect wafers with literally trillions of these devices. This is -really- hard because once you get down to nanoscales, thermodynamics fights against you every step of the way. You can make things easier by simplifying the requirements for assembly: eg instead of having nanotubes lay down on the surface to make circuits, just have them all forming parallel arrays pointing in one direction. Use lithography to define the other features that make up the circuit on top of them. Even so, it takes tons and tons of work. Finally, here's the one question that nobody has asked: Why carbon nanotubes? It turns out, it's not impossible for Intel or IBM to make transistors that are about as small as carbon nanotube transistors. The problem is that if the electricity flowing through the transistor is carried by silicon, there will be so much power dissipation that your CPU will literally melt itself before you can finish one game of Call of Duty. Semiconducting carbon nanotubes, are just about, the most power efficient semiconductors known. Graphene could be even better but it's actually not a semiconductor, so, no real good way to make it into a good transistor. So, carbon nanotubes are really, one of just a handful of materials that could possibly allow Moore's Law to continue down to transistors on the size of 10 nm wide or so, which is why IBM is still at it. (BTW, 10 nm transistor is not the same as a 10 nm node on the semiconductor roadmap. The 10 nm node actually has much bigger transistors). Anyways, I hope IBM succeeds. I'm rooting for them.

[@renzo5282]

[@CorMaestro]

Fascinating! I can only hope that carbon nanotube and graphene based technology reaches factory production in my lifetime. The uses of graphene alone, blows my mind! I can't help but think that if we were able to make an AI that could learn and do complex equations for us and assist us that our technological advancements would blow ahead by decades or even centuries. I digress though. Thank you for the more detailed explanation Mr. Han! When he explained the difficulties of aligning carbon nanotubes, I had thought they were going to employ the use of tiny robots to do it haha! Tiny robots with really tiny precise claws.

I think his intention was to encourage or inspire new nanotechnology´s scientists.

[@lawrencegalvan]

why is nanotechnology likened to creating a statue out of a pile of dust?? tho

[@Wesley-Insley-Comedy]

So the first step I was thinking was...you need a model or set of parameters for the particles to follow. Let's dumb it down and say it's a flower vase. Simple shape to make in a 3D modeling program. Then what if we set each point as a place for the particles to go. That is all sound hypothetically...but then how do you get the particles to move there? And what kind of particles are these? Could we somehow involve magnets or magnet fields? Way above my pay grade, but if I had the money for it I would invest heavily into this tech. Seems world changing

[@justDIY]

Sand sculptures are statues made from millions of tiny particles... at least I would consider that a statue made from a pile of dust, hardly impossible.

[@brunolima1997]

It's been a long time since I last watched something this good in this channel. Keep up like this!

[@Mornys]

When we learn to do this properly we can start creating open source computational hardware which can be expected to be safer than current hardware, because of possible manufacturer backdoors. Cheaper, smaller, faster, more power efficient and safer.

[@GETn2UNED]

Would be cool to Flash Build.. Have a computer linked to an area. The area full of electric chips or whatever. Flash the blueprint on the computer to the chips, therefore electrifying a hologram of the blueprint. Pump the nanotubes in and they'd begin to form around the hologram. After some time, turn off the hologram for the nanotubes to cool and become solid. -THIS IS ALL IMAGINARY-

Still damn waiting for a decent nano-coating I can have applied to my car (incl. windshield) so I never have to clean it again.

[@jeraldtango7790]

What are the possible innovation can nanotechnology can offer???

[@mechadense]

0:40 "The only way you get a statue out of dust is to let the statue build itself" 3:00 "We couldn't place one by one millions of particles together" This remarks are only true with the current state of technology. In the long run massively parallel pick and place positional assembly of single atoms (and bigger assemblies of them) to advanced systems is predictably much more performant and desirable than chemical synthesis (in liquid phase) and subsequent self assembly. Chemical synthesis (in liquid phase) and self assembly will be powerful tools though to get to positional assembly (more precisely: mechanosynthesis of diamondoid materials in machine phase). Also these soft/wet techniques may make early forms of nanotube-computers and other things the presenter is talking about possible a bit sooner - early forms. 7:18 "Mother nature builds everything this way". There are big areas where the capabilities of nature and the capabilities of human technology do not intersect. Both ways. While there is lots of nature we do not understand and can't replicate there are also many examples of human technology that are probably "eternally" inaccessible by incremental evolution.

Where are the nanobots? We have seen devices assemble themselves for various uses already. Why wasn't that referenced and expanded upon?

[@skripnigor]

josh71111 I admire all those nice people working on it. My sorrow is about the fact that we still don't see any tangible snippets of success. At least nothing on this TED talk. And I haven't found any practical implementations on the Foresight Institute website either. It's not to say I am not excited by the idea of nanotechnology. But my layman's impression is that in 2017 it's still nothing but an idea.

[@arjunjayakumar4518]

Give it time bro.These are at the highest levels of technology.So obviously, it takes time.

[@nathansmith3244]

At least he's figured out the biggest problem. Is you will never efficiently assemble them using any man made process. You need to rely on chemistry doing the work and then you can just mine the stuff. I can picture a company going to the coal mines filling them with a chemical solution that then converts the coal into carbon nano tubes maybe it takes 100 years for them to change but worth the wait.
