Dialogue: 0,0:00:00.95,0:00:02.67,Default,,0000,0000,0000,,I'm here to show you
Dialogue: 0,0:00:02.67,0:00:06.37,Default,,0000,0000,0000,,how something you can't see can be so much fun to look at.
Dialogue: 0,0:00:06.37,0:00:10.17,Default,,0000,0000,0000,,You're about to experience a new, available
Dialogue: 0,0:00:10.17,0:00:13.15,Default,,0000,0000,0000,,and exciting technology that's going to make us rethink
Dialogue: 0,0:00:13.15,0:00:15.28,Default,,0000,0000,0000,,how we waterproof our lives.
Dialogue: 0,0:00:15.28,0:00:18.00,Default,,0000,0000,0000,,What I have here is a cinder block
Dialogue: 0,0:00:18.00,0:00:20.50,Default,,0000,0000,0000,,that we've coated half with a nanotechnology spray
Dialogue: 0,0:00:20.50,0:00:23.09,Default,,0000,0000,0000,,that can be applied to almost any material.
Dialogue: 0,0:00:23.09,0:00:25.43,Default,,0000,0000,0000,,It's called Ultra-Ever Dry,
Dialogue: 0,0:00:25.43,0:00:27.85,Default,,0000,0000,0000,,and when you apply it to any material,
Dialogue: 0,0:00:27.85,0:00:30.96,Default,,0000,0000,0000,,it turns into a superhydrophobic shield.
Dialogue: 0,0:00:30.96,0:00:33.48,Default,,0000,0000,0000,,So this is a cinder block, uncoated,
Dialogue: 0,0:00:33.48,0:00:37.78,Default,,0000,0000,0000,,and you can see that it's porous, it absorbs water.
Dialogue: 0,0:00:37.78,0:00:40.44,Default,,0000,0000,0000,,Not anymore.
Dialogue: 0,0:00:40.44,0:00:44.67,Default,,0000,0000,0000,,Porous, nonporous.
Dialogue: 0,0:00:44.67,0:00:47.42,Default,,0000,0000,0000,,So what's superhydrophobic?
Dialogue: 0,0:00:47.42,0:00:49.91,Default,,0000,0000,0000,,Superhydrophobic is how we measure
Dialogue: 0,0:00:49.91,0:00:52.39,Default,,0000,0000,0000,,a drop of water on a surface.
Dialogue: 0,0:00:52.39,0:00:54.79,Default,,0000,0000,0000,,The rounder it is, the more hydrophobic it is,
Dialogue: 0,0:00:54.79,0:00:57.72,Default,,0000,0000,0000,,and if it's really round, it's superhydrophobic.
Dialogue: 0,0:00:57.72,0:01:00.67,Default,,0000,0000,0000,,A freshly waxed car, the water molecules slump
Dialogue: 0,0:01:00.67,0:01:03.61,Default,,0000,0000,0000,,to about 90 degrees.
Dialogue: 0,0:01:03.61,0:01:06.70,Default,,0000,0000,0000,,A windshield coating is going to give you about 110 degrees.
Dialogue: 0,0:01:06.70,0:01:09.48,Default,,0000,0000,0000,,But what you're seeing here is 160 to 175 degrees,
Dialogue: 0,0:01:09.48,0:01:13.49,Default,,0000,0000,0000,,and anything over 150 is superhydrophobic.
Dialogue: 0,0:01:13.49,0:01:15.04,Default,,0000,0000,0000,,So as part of the demonstration,
Dialogue: 0,0:01:15.04,0:01:17.55,Default,,0000,0000,0000,,what I have is a pair of gloves,
Dialogue: 0,0:01:17.55,0:01:19.72,Default,,0000,0000,0000,,and we've coated one of the gloves
Dialogue: 0,0:01:19.72,0:01:22.42,Default,,0000,0000,0000,,with the nanotechnology coating,
Dialogue: 0,0:01:22.42,0:01:24.22,Default,,0000,0000,0000,,and let's see if you can tell which one,
Dialogue: 0,0:01:24.22,0:01:26.56,Default,,0000,0000,0000,,and I'll give you a hint.
Dialogue: 0,0:01:31.28,0:01:35.90,Default,,0000,0000,0000,,Did you guess the one that was dry?
Dialogue: 0,0:01:35.90,0:01:40.61,Default,,0000,0000,0000,,When you have nanotechnology and nanoscience,
Dialogue: 0,0:01:40.61,0:01:43.28,Default,,0000,0000,0000,,what's occurred is that we're able to now
Dialogue: 0,0:01:43.28,0:01:45.79,Default,,0000,0000,0000,,look at atoms and molecules and actually control them
Dialogue: 0,0:01:45.79,0:01:48.22,Default,,0000,0000,0000,,for great benefits.
Dialogue: 0,0:01:48.22,0:01:50.22,Default,,0000,0000,0000,,And we're talking really small here.
Dialogue: 0,0:01:50.22,0:01:52.49,Default,,0000,0000,0000,,The way you measure nanotechnology is in nanometers,
Dialogue: 0,0:01:52.49,0:01:56.32,Default,,0000,0000,0000,,and one nanometer is a billionth of a meter,
Dialogue: 0,0:01:56.32,0:01:57.97,Default,,0000,0000,0000,,and to put some scale to that,
Dialogue: 0,0:01:57.97,0:02:01.27,Default,,0000,0000,0000,,if you had a nanoparticle that was one nanometer thick,
Dialogue: 0,0:02:01.27,0:02:04.09,Default,,0000,0000,0000,,and you put it side by side, and you had 50,000 of them,
Dialogue: 0,0:02:04.09,0:02:06.94,Default,,0000,0000,0000,,you'd be the width of a human hair.
Dialogue: 0,0:02:06.94,0:02:09.94,Default,,0000,0000,0000,,So very small, but very useful.
Dialogue: 0,0:02:09.94,0:02:12.85,Default,,0000,0000,0000,,And it's not just water that this works with.
Dialogue: 0,0:02:12.85,0:02:15.60,Default,,0000,0000,0000,,It's a lot of water-based materials like concrete,
Dialogue: 0,0:02:15.60,0:02:17.77,Default,,0000,0000,0000,,water-based paint,
Dialogue: 0,0:02:17.77,0:02:19.42,Default,,0000,0000,0000,,mud,
Dialogue: 0,0:02:19.42,0:02:22.80,Default,,0000,0000,0000,,and also some refined oils as well.
Dialogue: 0,0:02:27.22,0:02:31.60,Default,,0000,0000,0000,,You can see the difference.
Dialogue: 0,0:02:31.60,0:02:33.10,Default,,0000,0000,0000,,Moving onto the next demonstration,
Dialogue: 0,0:02:33.10,0:02:35.39,Default,,0000,0000,0000,,we've taken a pane of glass and we've coated the outside of it,
Dialogue: 0,0:02:35.39,0:02:38.64,Default,,0000,0000,0000,,we've framed it with the nanotechnology coating,
Dialogue: 0,0:02:38.64,0:02:42.41,Default,,0000,0000,0000,,and we're going to pour this green-tinted water inside the middle,
Dialogue: 0,0:02:42.41,0:02:44.38,Default,,0000,0000,0000,,and you're going to see, it's going to spread out on glass
Dialogue: 0,0:02:44.38,0:02:45.92,Default,,0000,0000,0000,,like you'd normally think it would,
Dialogue: 0,0:02:45.92,0:02:49.52,Default,,0000,0000,0000,,except when it hits the coating, it stops,
Dialogue: 0,0:02:49.52,0:02:53.30,Default,,0000,0000,0000,,and I can't even coax it to leave.
Dialogue: 0,0:02:53.30,0:02:54.91,Default,,0000,0000,0000,,It's that afraid of the water.
Dialogue: 0,0:02:54.91,0:02:58.63,Default,,0000,0000,0000,,(Applause)
Dialogue: 0,0:02:58.63,0:03:00.38,Default,,0000,0000,0000,,So what's going on here? What's happening?
Dialogue: 0,0:03:00.38,0:03:03.67,Default,,0000,0000,0000,,Well, the surface of the spray coating
Dialogue: 0,0:03:03.67,0:03:05.43,Default,,0000,0000,0000,,is actually filled with nanoparticles
Dialogue: 0,0:03:05.43,0:03:07.50,Default,,0000,0000,0000,,that form a very rough and craggly surface.
Dialogue: 0,0:03:07.50,0:03:10.09,Default,,0000,0000,0000,,You'd think it'd be smooth, but it's actually not.
Dialogue: 0,0:03:10.09,0:03:12.86,Default,,0000,0000,0000,,And it has billions of interstitial spaces,
Dialogue: 0,0:03:12.86,0:03:15.97,Default,,0000,0000,0000,,and those spaces, along with the nanoparticles,
Dialogue: 0,0:03:15.97,0:03:18.32,Default,,0000,0000,0000,,reach up and grab the air molecules,
Dialogue: 0,0:03:18.32,0:03:20.39,Default,,0000,0000,0000,,and cover the surface with air.
Dialogue: 0,0:03:20.39,0:03:23.13,Default,,0000,0000,0000,,It's an umbrella of air all across it,
Dialogue: 0,0:03:23.13,0:03:25.77,Default,,0000,0000,0000,,and that layer of air is what the water hits,
Dialogue: 0,0:03:25.77,0:03:28.82,Default,,0000,0000,0000,,the mud hits, the concrete hits, and it glides right off.
Dialogue: 0,0:03:28.82,0:03:30.84,Default,,0000,0000,0000,,So if I put this inside this water here,
Dialogue: 0,0:03:30.84,0:03:34.96,Default,,0000,0000,0000,,you can see a silver reflective coating around it,
Dialogue: 0,0:03:34.96,0:03:36.41,Default,,0000,0000,0000,,and that silver reflective coating
Dialogue: 0,0:03:36.41,0:03:38.68,Default,,0000,0000,0000,,is the layer of air that's protecting the water
Dialogue: 0,0:03:38.68,0:03:42.45,Default,,0000,0000,0000,,from touching the paddle, and it's dry.
Dialogue: 0,0:03:45.34,0:03:47.84,Default,,0000,0000,0000,,So what are the applications?
Dialogue: 0,0:03:47.84,0:03:50.28,Default,,0000,0000,0000,,I mean, many of you right now are probably going through your head.
Dialogue: 0,0:03:50.28,0:03:51.78,Default,,0000,0000,0000,,Everyone that sees this gets excited, and says,
Dialogue: 0,0:03:51.78,0:03:53.71,Default,,0000,0000,0000,,"Oh, I could use it for this and this and this."
Dialogue: 0,0:03:53.71,0:03:55.77,Default,,0000,0000,0000,,The applications in a general sense
Dialogue: 0,0:03:55.77,0:03:58.60,Default,,0000,0000,0000,,could be anything that's anti-wetting.
Dialogue: 0,0:03:58.60,0:04:00.87,Default,,0000,0000,0000,,We've certainly seen that today.
Dialogue: 0,0:04:00.87,0:04:03.45,Default,,0000,0000,0000,,It could be anything that's anti-icing,
Dialogue: 0,0:04:03.45,0:04:06.91,Default,,0000,0000,0000,,because if you don't have water, you don't have ice.
Dialogue: 0,0:04:06.91,0:04:09.18,Default,,0000,0000,0000,,It could be anti-corrosion.
Dialogue: 0,0:04:09.18,0:04:11.21,Default,,0000,0000,0000,,No water, no corrosion.
Dialogue: 0,0:04:11.21,0:04:13.40,Default,,0000,0000,0000,,It could be anti-bacterial.
Dialogue: 0,0:04:13.40,0:04:16.11,Default,,0000,0000,0000,,Without water, the bacteria won't survive.
Dialogue: 0,0:04:16.11,0:04:19.93,Default,,0000,0000,0000,,And it could be things that need to be self-cleaning as well.
Dialogue: 0,0:04:21.63,0:04:25.50,Default,,0000,0000,0000,,So imagine how something like this
Dialogue: 0,0:04:25.50,0:04:29.62,Default,,0000,0000,0000,,could help revolutionize your field of work.
Dialogue: 0,0:04:29.62,0:04:32.02,Default,,0000,0000,0000,,And I'm going to leave you with one last demonstration,
Dialogue: 0,0:04:32.02,0:04:34.62,Default,,0000,0000,0000,,but before I do that, I would like to say thank you,
Dialogue: 0,0:04:34.62,0:04:36.66,Default,,0000,0000,0000,,and think small.
Dialogue: 0,0:04:45.10,0:04:52.65,Default,,0000,0000,0000,,(Applause)
Dialogue: 0,0:04:52.65,0:04:57.04,Default,,0000,0000,0000,,It's going to happen. Wait for it. Wait for it.
Dialogue: 0,0:04:57.04,0:05:01.82,Default,,0000,0000,0000,,Chris Anderson: You guys didn't hear about us cutting out the Design from TED? (Laughter)
Dialogue: 0,0:05:01.82,0:05:03.57,Default,,0000,0000,0000,,[Two minutes later...]
Dialogue: 0,0:05:03.57,0:05:06.25,Default,,0000,0000,0000,,He ran into all sorts of problems in terms of managing the medical research part.
Dialogue: 0,0:05:06.25,0:05:08.81,Default,,0000,0000,0000,,It's happening!
Dialogue: 0,0:05:08.81,0:05:12.81,Default,,0000,0000,0000,,(Applause)
