I'm here to show you
1
12946
1724
Ukážem vám,
00:14
how something you can't see can be so much fun to look at.
2
14670
3701
aká zábava je vidieť neviditeľné.
00:18
You're about to experience a new, available
3
18371
3803
Zažijete novú, dostupnú a vzrušujúcu
00:22
and exciting technology that's going to make us rethink
4
22174
2980
technológiu, ktorá pomôže prehodnotiť
00:25
how we waterproof our lives.
5
25154
2128
spôsob, akým utesňujeme naše životy.
00:27
What I have here is a cinder block
6
27282
2720
Mám tu tvárnicu, jednu
00:30
that we've coated half with a nanotechnology spray
7
30002
2496
polovicu som nasprejoval nanotechnologickým sprejom,
00:32
that can be applied to almost any material.
8
32498
2592
aplikovateľným takmer na každý materiál.
00:35
It's called Ultra-Ever Dry,
9
35090
2337
Volá sa Ultra-Ever Dry (vždy-ultra-suchý),
00:37
and when you apply it to any material,
10
37427
2426
jeho aplikáciou na akýkoľvek materiál
00:39
it turns into a superhydrophobic shield.
11
39853
3105
sa premení na superhydrofóbny štít.
00:42
So this is a cinder block, uncoated,
12
42958
2526
Toto je tvárnica, nenasprejovaná
00:45
and you can see that it's porous, it absorbs water.
13
45484
4301
a vidíte, že má póry, absorbuje vodu.
00:49
Not anymore.
14
49785
2654
A už nie.
00:52
Porous, nonporous.
15
52439
4227
Pórovitá, nepórovitá.
00:56
So what's superhydrophobic?
16
56666
2752
Čo znamená superhydrofóbna?
00:59
Superhydrophobic is how we measure
17
59418
2493
Superhydrofóbnosťou meriame
01:01
a drop of water on a surface.
18
61911
2482
kvapku vody na povrchu.
01:04
The rounder it is, the more hydrophobic it is,
19
64393
2400
Čím okrúhlejšia, tým je hydrofóbnejšia,
01:06
and if it's really round, it's superhydrophobic.
20
66793
2928
úplne okrúhla je superhydrofóbna.
01:09
A freshly waxed car, the water molecules slump
21
69721
2946
Na čerstvo navoskovanom aute
01:12
to about 90 degrees.
22
72667
2940
molekuly vody klesnú na 90 stupňov.
01:15
A windshield coating is going to give you about 110 degrees.
23
75607
3088
Neprefúkavé oblečenie dá okolo 110 stupňov.
01:18
But what you're seeing here is 160 to 175 degrees,
24
78695
2781
Ale tu vidíte 160 až 175 stupňov.
01:21
and anything over 150 is superhydrophobic.
25
81476
4012
Všetko nad 150 je superhydrofóbne.
01:25
So as part of the demonstration,
26
85488
1549
Súčasťou demonštrácie
01:27
what I have is a pair of gloves,
27
87037
2514
sú aj rukavice.
01:29
and we've coated one of the gloves
28
89551
2168
Jedna je nasprejovaná
01:31
with the nanotechnology coating,
29
91719
2704
nanotechnologickým prípravkom.
01:34
and let's see if you can tell which one,
30
94423
1800
Uvidíme, či zbadáte, ktorá.
01:36
and I'll give you a hint.
31
96223
2336
Dám Vám nápovedu.
01:43
Did you guess the one that was dry?
32
103280
4624
Typovali ste na suchú?
01:47
When you have nanotechnology and nanoscience,
33
107904
4702
S nanotechnológiou a nanovedou
01:52
what's occurred is that we're able to now
34
112606
2672
sme schopný sa zrazu
01:55
look at atoms and molecules and actually control them
35
115278
2513
pozrieť na atómy a molekuly a
01:57
for great benefits.
36
117791
2432
kontrolovať ich v náš prospech.
02:00
And we're talking really small here.
37
120223
1999
Hovoríme o fakt malých rozmeroch.
02:02
The way you measure nanotechnology is in nanometers,
38
122222
2272
Mierka nanotechnológie sú nanometre,
02:04
and one nanometer is a billionth of a meter,
39
124494
3827
Jeden nanometer je miliardtina metra.
02:08
and to put some scale to that,
40
128321
1647
Na porovnanie,
02:09
if you had a nanoparticle that was one nanometer thick,
41
129968
3306
jedna nanočastica o hrúbke 1 nm vedľa druhej,
02:13
and you put it side by side, and you had 50,000 of them,
42
133274
2815
dokopy 50,000 nanočastíc
02:16
you'd be the width of a human hair.
43
136089
2848
by mali šírku ľudského vlasu.
02:18
So very small, but very useful.
44
138937
3008
Takže malinké, a veľmi užitočné.
02:21
And it's not just water that this works with.
45
141945
2904
Funguje to nielen s vodou ale aj
02:24
It's a lot of water-based materials like concrete,
46
144849
2751
mnohými materiálmi na vodnej báze ako
02:27
water-based paint,
47
147600
2169
betón, farby,
02:29
mud,
48
149769
1648
blato,
02:31
and also some refined oils as well.
49
151417
3383
a niektoré rafinované oleje.
02:39
You can see the difference.
50
159216
4389
Vidíte ten rozdiel.
02:43
Moving onto the next demonstration,
51
163605
1490
Pokračujme ďalšou demonštráciou.
02:45
we've taken a pane of glass and we've coated the outside of it,
52
165095
2294
Po pokrytí okrajov skla
02:47
we've framed it with the nanotechnology coating,
53
167389
3250
nanotechnologickým plášťom
02:50
and we're going to pour this green-tinted water inside the middle,
54
170639
3775
nalejeme vstred zelenú vodu
02:54
and you're going to see, it's going to spread out on glass
55
174414
1961
a vidíme ako sa leje
02:56
like you'd normally think it would,
56
176375
1550
normálne až po hranicu,
02:57
except when it hits the coating, it stops,
57
177925
3594
za ktorú
03:01
and I can't even coax it to leave.
58
181519
3785
ju už nevyženiem.
03:05
It's that afraid of the water.
59
185304
1603
Tak veľmi sa jej bojí.
03:06
(Applause)
60
186907
3720
(Aplauz)
03:10
So what's going on here? What's happening?
61
190627
1752
Čo sa deje?
03:12
Well, the surface of the spray coating
62
192379
3288
Povrch nasprejovaným plášťom
03:15
is actually filled with nanoparticles
63
195667
1761
je plný nanočastíc,
03:17
that form a very rough and craggly surface.
64
197428
2074
ktoré tvoria drsný až 'skalnatý' povrch.
03:19
You'd think it'd be smooth, but it's actually not.
65
199502
2589
Vyzerá hladký, ale nie je.
03:22
And it has billions of interstitial spaces,
66
202091
2771
Má miliardy voľných priestorov,
03:24
and those spaces, along with the nanoparticles,
67
204862
3109
ktoré spolu s nanočasticami
03:27
reach up and grab the air molecules,
68
207971
2352
priťahujú molekuly vzduchu
03:30
and cover the surface with air.
69
210323
2063
a pokrývajú nimi povrch.
03:32
It's an umbrella of air all across it,
70
212386
2745
Ako dáždnik potiahnutý vzduchom,
03:35
and that layer of air is what the water hits,
71
215131
2640
na ktorý naráža voda,
03:37
the mud hits, the concrete hits, and it glides right off.
72
217771
3048
blato a betón, a stekajú z neho.
03:40
So if I put this inside this water here,
73
220819
2016
Ponorením tohoto do vody
03:42
you can see a silver reflective coating around it,
74
222835
4120
vidíte strieborný lesklý plášť,
03:46
and that silver reflective coating
75
226955
1456
ktorý je
03:48
is the layer of air that's protecting the water
76
228411
2271
vzdušnou blanou brániacou vode v
03:50
from touching the paddle, and it's dry.
77
230682
3767
dotyku s pádlom. Je suché.
03:57
So what are the applications?
78
237340
2497
Aké sú aplikácie?
03:59
I mean, many of you right now are probably going through your head.
79
239837
2448
Mnohým z Vás víri hlavou.
04:02
Everyone that sees this gets excited, and says,
80
242285
1498
Kto toto vidí, hovorí nadšene
04:03
"Oh, I could use it for this and this and this."
81
243783
1929
"Dá sa to použiť na to a tamto."
04:05
The applications in a general sense
82
245712
2062
Aplikácie sú všeobecne
04:07
could be anything that's anti-wetting.
83
247774
2830
čokoľvek proti zamočeniu,
04:10
We've certainly seen that today.
84
250604
2265
čo sme práve videli.
04:12
It could be anything that's anti-icing,
85
252869
2584
Môže to byť čokoľvek nemrznúce,
04:15
because if you don't have water, you don't have ice.
86
255453
3455
lebo bez vody nebude ľad.
04:18
It could be anti-corrosion.
87
258908
2272
Čokoľvek anti-korózne.
04:21
No water, no corrosion.
88
261180
2026
bez vody nebude korózia.
04:23
It could be anti-bacterial.
89
263206
2198
Čokoľvek anti-bakteriálne.
04:25
Without water, the bacteria won't survive.
90
265404
2709
Bez vody baktérie neprežijú.
04:28
And it could be things that need to be self-cleaning as well.
91
268113
3819
Čokoľvek samočistiace.
04:33
So imagine how something like this
92
273629
3872
Predstavte si, ako to môže
04:37
could help revolutionize your field of work.
93
277501
4121
priniesť revolúciu vo vašej oblasti.
04:41
And I'm going to leave you with one last demonstration,
94
281622
2399
Kým vas opustím s poslednou demonštráciou,
04:44
but before I do that, I would like to say thank you,
95
284021
2601
chcem sa Vám poďakovať,
04:46
and think small.
96
286622
2043
myslite v malom!
04:57
(Applause)
97
297098
7548
(Aplauz)
05:04
It's going to happen. Wait for it. Wait for it.
98
304646
4389
Príde to. Počkajte. Čakajte.
05:09
Chris Anderson: You guys didn't hear about us cutting out the Design from TED? (Laughter)
99
309035
4782
Chris Anderson: "Nepočuli ste, že Design sme z TED-u vystrihli?" (Smiech)
05:13
[Two minutes later...]
100
313817
1750
(Dve minúty neskôr....)
05:15
He ran into all sorts of problems in terms of managing the medical research part.
101
315567
2684
Narazil na problémy so zdravotnou časťou tohto výskumu.
05:18
It's happening!
102
318251
2563
Ono sa to deje!
05:20
(Applause)
103
320814
