I'm here to show you

Gaur, ikusi ezin duzuen zerbait behatzea

how something you can't see can be so much fun to look at.

zein dibertigarria den erakusteko nago hemen.

You're about to experience a new, available

Teknologia berri, baliozko eta

and exciting technology that's going to make us rethink

zoragarri bat probatzear zaudete, gure bizitza nola iragazten dugun

how we waterproof our lives.

pentsatzera eramango gaituena hain zuzen ere.

What I have here is a cinder block

Hemen dudana errauts bloke bat da

that we've coated half with a nanotechnology spray

eta erdia nanoteknologia spray batekin estali dut,

that can be applied to almost any material.

ia material guztiei aplika daitekeen spray bat.

It's called Ultra-Ever Dry,

Ultra-Ever Dry du izena

and when you apply it to any material,

eta edozein materiali aplikatzean

it turns into a superhydrophobic shield.

babeski superhidrofobiko bihurtzen da.

So this is a cinder block, uncoated,

Beraz, hau errauts bloke bat da, ezerekin estali gabe dago,

and you can see that it's porous, it absorbs water.

eta ikus dezakezuen bezala porotsua da, ura xurgatzen du.

Not anymore.

Baina honek ez.

Porous, nonporous.

Porotsua, iragazgaitza.

So what's superhydrophobic?

Orduan, zer da superhidrofobikoa?

Superhydrophobic is how we measure

Superhidrofobikoa ur tanta bat edozein gainazaletan

a drop of water on a surface.

neurtzea da.

The rounder it is, the more hydrophobic it is,

Geroz eta borobilagoa, orduan eta hidrofobikoagoa da

and if it's really round, it's superhydrophobic.

eta borobil-borobila bada, superhidrofobikoa da.

A freshly waxed car, the water molecules slump

Ezkoztatutako auto batean ur molekulak

to about 90 degrees.

90 bat gradutan erortzen dira.

A windshield coating is going to give you about 110 degrees.

Haizetako estaldura batek 110 bat gradu emango dizkigu.

But what you're seeing here is 160 to 175 degrees,

Baina hemen ikusten ari garena 160 eta 175 gradu tartean dago.

and anything over 150 is superhydrophobic.

150 baino gehiagotara dagoen edozer superhidrofobikoa da.

So as part of the demonstration,

Frogapen honetako atal honetan

what I have is a pair of gloves,

pare bat eskularru ditut

and we've coated one of the gloves

eta bat nanotekologia estalkiarekin

with the nanotechnology coating,

gainkatu dut.

and let's see if you can tell which one,

Ikus dezagun ea esan diezadakezuen zein

and I'll give you a hint.

eta nik seinale bat emango dizuet.

Did you guess the one that was dry?

Asmatu al duzue zein zegoen lehor?

When you have nanotechnology and nanoscience,

Nanoteknologia eta nanozientzia

what's occurred is that we're able to now

dugunean zera gertatzen da,

look at atoms and molecules and actually control them

onura askotarako atomo eta molekulak behatu

for great benefits.

eta kontrolatzeko gai garela.

And we're talking really small here.

Hau ez da garrantzitsuena;

The way you measure nanotechnology is in nanometers,

nanoteknologia nanometroetan neurtzen da

and one nanometer is a billionth of a meter,

eta nanometro bat metro bat milioi bat zatitan zatituz gero, horietako bakoitza da.

and to put some scale to that,

Argiago ikus dezagun:

if you had a nanoparticle that was one nanometer thick,

nanometro bat neurtzen duen nanopartikula bat badugu,

and you put it side by side, and you had 50,000 of them,

eta guztira elkarren ondoan horietako 50 000 jartzen baditugu,

you'd be the width of a human hair.

gizakion ile baten zabalera izango luke guztira.

So very small, but very useful.

Oso txikia beraz, baina era berean oso erabilgarria.

And it's not just water that this works with.

Eta ez du urarekin bakarrik funtzionatzen,

It's a lot of water-based materials like concrete,

urean oinarritutako material askorekin baizik, hormigoiarein,

water-based paint,

urean oinarritutako margoekin,

mud,

lokatzarekin edota

and also some refined oils as well.

findutako olioekin, besteak beste.

You can see the difference.

Aldea ikus dezaezue.

Moving onto the next demonstration,

Hurrengo frogapenera pasatuko gara.

we've taken a pane of glass and we've coated the outside of it,

Beira zati bat hartu dugu eta

we've framed it with the nanotechnology coating,

nanoteknologia babeskiarekin inguratu dugu.

and we're going to pour this green-tinted water inside the middle,

Orain berdez tindatutako ur hau botako dugu erdiko zatira

and you're going to see, it's going to spread out on glass

eta ikusiko duzuen bezala, beiran zehar zabalduko da,

like you'd normally think it would,

pentsatzen zenuten moduan,

except when it hits the coating, it stops,

baina babeskira iristen denean gelditu egiten da

and I can't even coax it to leave.

eta ezin dut ezer egin gehiago barreiatzeko.

It's that afraid of the water.

Urari beldur dio.

(Applause)

(Txaloak)

So what's going on here? What's happening?

Orduan, zer da gertatzen dena?

Well, the surface of the spray coating

Spray estalkiaren gainazala

is actually filled with nanoparticles

nanopartikulez beteta dago eta

that form a very rough and craggly surface.

oso gainazal sendoa izatea eragiten du honek.

You'd think it'd be smooth, but it's actually not.

Leuna dela pentsatuko zenuten beharbada, baina ez.

And it has billions of interstitial spaces,

Gainera, bilioka espazio interstizio ditu

and those spaces, along with the nanoparticles,

eta nanopartikulekin batera, espazio horiek

reach up and grab the air molecules,

goruntz joaten dira eta aire molekulak hartzen dituzte,

and cover the surface with air.

modu honetan gainazala airez estaliz.

It's an umbrella of air all across it,

Airezko aterki bat bezala da;

and that layer of air is what the water hits,

airezko kapa horri egiten dio urak,

the mud hits, the concrete hits, and it glides right off.

lokatzak edo hormigoiak talka eta berehala irristatzen da.

So if I put this inside this water here,

Honako objektu hau uretan sartzen badut

you can see a silver reflective coating around it,

zilar koloreko babeski islatzaile bat ikus daiteke inguruan,

and that silver reflective coating

eta zilar koloreko babeski islatzaile hori

is the layer of air that's protecting the water

ura arraunetik babesten duen airezko kapa da

from touching the paddle, and it's dry.

eta lehorra dago.

So what are the applications?

Zeintzuk dira honen onurak edo abantailak?

I mean, many of you right now are probably going through your head.

Ziurrenik zuetako asko hori ari zarete galdetzen zuen buruari.

Everyone that sees this gets excited, and says,

Guztiei izugarri gustatzen zaie hau eta zera esaten dute:

"Oh, I could use it for this and this and this."

"Honetarako eta honetarako eta beste honetarako erabili dezaket"

The applications in a general sense

Orokorrean ez hezetzeko edozein

could be anything that's anti-wetting.

gauzari aplika daiteke.

We've certainly seen that today.

Hori ikusi dugu gaur hemen.

It could be anything that's anti-icing,

Ez izozteko ere erabil daiteke,

because if you don't have water, you don't have ice.

ura izan ezean ezin baitugu izotzik eduki.

It could be anti-corrosion.

Ez herdoiltzeko ere bai:

No water, no corrosion.

ez badago urik, ezin da ezer herdoildu.

It could be anti-bacterial.

Bakterien aurka ere erabil daiteke,

Without water, the bacteria won't survive.

urik gabe bakteriek ez bailukete biziraungo.

And it could be things that need to be self-cleaning as well.

Gauzak bakarrik garbi daitezen ere bai.

So imagine how something like this

Irudikatu horrelako zerbaitek nola alda dezakeen

could help revolutionize your field of work.

zuen lan eremua goitik behera.

And I'm going to leave you with one last demonstration,

Eta azkeneko frogapen bat egingo dugu orain,

but before I do that, I would like to say thank you,

baina hasi aurretik eskerrak eman nahi dizkizuet,

and think small.

eta baita modu sinplean pentsatzeko aholkatu.

(Applause)

(Txaloak)

It's going to happen. Wait for it. Wait for it.

Gertatuko da. Itxaron. Itxaron.

Chris Anderson: You guys didn't hear about us cutting out the Design from TED? (Laughter)

Chris Anderson: Ez al diguzue entzun TED-en diseinua mozten? (Barreak)

[Two minutes later...]

[Bi minutu geroago...]

He ran into all sorts of problems in terms of managing the medical research part.

Mediku ikerketa zuzentzeko era guztietako arazoiak izan zituen

It's happening!

Gertatzen ari da, begira!

(Applause)
