I'm here to show you

Jeg er her for at vise jer
00:14
how something you can't see can be so much fun to look at.
1
2670
3701
hvordan noget man ikke kan se, kan være så sjovt at kigge på.
00:18
You're about to experience a new, available
2
6371
3803
Om lidt vil I opleve en ny, tilgængelig
00:22
and exciting technology that's going to make us rethink
3
10174
2980
og spændende teknologi der vil få os til at genoverveje
00:25
how we waterproof our lives.
4
13154
2128
hvordan vi gør vores liv vandtætte.
00:27
What I have here is a cinder block
5
15282
2720
Det, jeg har her, er en cementblok
00:30
that we've coated half with a nanotechnology spray
6
18002
2496
som vi har belagt halvt med nanoteknologisk spray
00:32
that can be applied to almost any material.
7
20498
2592
der kan anvendes på næsten ethvert materiale.
00:35
It's called Ultra-Ever Dry,
8
23090
2337
Det hedder Ultra-Ever Dry,
00:37
and when you apply it to any material,
9
25427
2426
og når man påfører det på et hvilket som helst materiale
00:39
it turns into a superhydrophobic shield.
10
27853
3105
forvandler det sig til et superhydrofobisk skjold.
00:42
So this is a cinder block, uncoated,
11
30958
2526
Dette er en cementblok, ubehandlet,
00:45
and you can see that it's porous, it absorbs water.
12
33484
4301
og som I ser er den porøs; den absorberer vand.
00:49
Not anymore.
13
37785
2654
Ikke længere.
00:52
Porous, nonporous.
14
40439
4227
Porøs, ikke porøs.
00:56
So what's superhydrophobic?
15
44666
2752
Men hvad betyder "superhydrofobisk"?
00:59
Superhydrophobic is how we measure
16
47418
2493
Superhydrofobi er den måde vi måler
01:01
a drop of water on a surface.
17
49911
2482
en dråbe vand på en overflade.
01:04
The rounder it is, the more hydrophobic it is,
18
52393
2400
Jo rundere dråbe, jo mere hydrofobisk er overfladen,
01:06
and if it's really round, it's superhydrophobic.
19
54793
2928
og hvis den er virkelig rund, er overfladen superhydrofobisk.
01:09
A freshly waxed car, the water molecules slump
20
57721
2946
På en nyvokset bil falder vandmolekulerne sammen
01:12
to about 90 degrees.
21
60667
2940
til cirka 90 grader.
01:15
A windshield coating is going to give you about 110 degrees.
22
63607
3088
En belagt forrude vil resultere i 110 grader.
01:18
But what you're seeing here is 160 to 175 degrees,
23
66695
2781
Men det I ser her, er 160 til 175 grader,
01:21
and anything over 150 is superhydrophobic.
24
69476
4012
og alt over 150 er superhydrofobisk.
01:25
So as part of the demonstration,
25
73488
1549
Som en del af demonstrationen,
01:27
what I have is a pair of gloves,
26
75037
2514
har jeg et par handsker,
01:29
and we've coated one of the gloves
27
77551
2168
og jeg har belagt en af handskerne
01:31
with the nanotechnology coating,
28
79719
2704
med den nanoteknologiske belægning,
01:34
and let's see if you can tell which one,
29
82423
1800
og lad os se, om I kan gætte hvilken en det er,
01:36
and I'll give you a hint.
30
84223
2336
-- jeg vil give jer et vink.
01:43
Did you guess the one that was dry?
31
91280
4624
Kunne I gætte hvilken der var tør?
01:47
When you have nanotechnology and nanoscience,
32
95904
4702
Når man har nanoteknologi og nanovidenskab,
01:52
what's occurred is that we're able to now
33
100606
2672
er vi nu pludselig i stand til
01:55
look at atoms and molecules and actually control them
34
103278
2513
at se på atomer og molekuler og faktisk kontrollere dem
01:57
for great benefits.
35
105791
2432
med store fordele.
02:00
And we're talking really small here.
36
108223
1999
Og vi taler om noget virkelig småt her.
02:02
The way you measure nanotechnology is in nanometers,
37
110222
2272
Måden man måler nanoteknologi på, er i nanometer,
02:04
and one nanometer is a billionth of a meter,
38
112494
3827
og en nanometer er en milliardtedel af en meter,
02:08
and to put some scale to that,
39
116321
1647
og for at sætte det ind i et målestoksforhold:
02:09
if you had a nanoparticle that was one nanometer thick,
40
117968
3306
Hvis man har en nanopartikel der er en nanometer tyk,
02:13
and you put it side by side, and you had 50,000 of them,
41
121274
2815
og man sætter dem side om side, og man har 50.000 af dem,
02:16
you'd be the width of a human hair.
42
124089
2848
så har man bredden af et menneskehår.
02:18
So very small, but very useful.
43
126937
3008
Meget småt, men meget brugbart.
02:21
And it's not just water that this works with.
44
129945
2904
Og det er ikke kun vand dette virker med.
02:24
It's a lot of water-based materials like concrete,
45
132849
2751
Det er mange vandbaserede materialer som cement,
02:27
water-based paint,
46
135600
2169
vandbaseret maling,
02:29
mud,
47
137769
1648
mudder,
02:31
and also some refined oils as well.
48
139417
3383
og også nogle typer raffineret olie.
02:39
You can see the difference.
49
147216
4389
Man kan se forskellen.
02:43
Moving onto the next demonstration,
50
151605
1490
Vi går videre til den næste demonstration,
02:45
we've taken a pane of glass and we've coated the outside of it,
51
153095
2294
hvor vi har taget glasrude og vi har belagt ydersiden,
02:47
we've framed it with the nanotechnology coating,
52
155389
3250
vi har indrammet den med nanoteknologi-beklædningen,
02:50
and we're going to pour this green-tinted water inside the middle,
53
158639
3775
og vi hælder dette farvede grønne vand ind i midten,
02:54
and you're going to see, it's going to spread out on glass
54
162414
1961
og som I kommer til at se, vil det sprede sig ud på glasset
02:56
like you'd normally think it would,
55
164375
1550
ligesom man normalt ville forvente det gjorde,
02:57
except when it hits the coating, it stops,
56
165925
3594
bortset fra at når det rammer belægningen, så stopper det,
03:01
and I can't even coax it to leave.
57
169519
3785
og jeg kan ikke engang lokke det til at forsvinde.
03:05
It's that afraid of the water.
58
173304
1603
Så bange er det for vandet.
03:06
(Applause)
59
174907
3720
(Bifald)
03:10
So what's going on here? What's happening?
60
178627
1752
Hvad foregår der her? Hvad er det der sker?
03:12
Well, the surface of the spray coating
61
180379
3288
Jamen, spraybelægningens overflade
03:15
is actually filled with nanoparticles
62
183667
1761
er faktisk fyldt med nanopartikler
03:17
that form a very rough and craggly surface.
63
185428
2074
der danner en meget ru og forreven overflade.
03:19
You'd think it'd be smooth, but it's actually not.
64
187502
2589
Man skulle tro at den er glat, men det er den ikke.
03:22
And it has billions of interstitial spaces,
65
190091
2771
Og den har milliarder af interstitielle rum,
03:24
and those spaces, along with the nanoparticles,
66
192862
3109
og de rum, sammen med nanopartiklerne,
03:27
reach up and grab the air molecules,
67
195971
2352
rækker op og tager fat i luftmolekylerne,
03:30
and cover the surface with air.
68
198323
2063
og dækker overfladen med luft.
03:32
It's an umbrella of air all across it,
69
200386
2745
Det er en paraply af luft over hele overfladen,
03:35
and that layer of air is what the water hits,
70
203131
2640
og det luftlag er det, vandet rammer,
03:37
the mud hits, the concrete hits, and it glides right off.
71
205771
3048
mudderet rammer, cementen rammer, og det glider lige af.
03:40
So if I put this inside this water here,
72
208819
2016
Hvis jeg sætter det ned i vandet her,
03:42
you can see a silver reflective coating around it,
73
210835
4120
kan man se den sølvfarvede reflektion af belægningen,
03:46
and that silver reflective coating
74
214955
1456
og den sølvfarvede reflekterende belægning
03:48
is the layer of air that's protecting the water
75
216411
2271
er det lag af luft der beskytter vandet
03:50
from touching the paddle, and it's dry.
76
218682
3767
fra at røre ved padlen, og det er tørt.
03:57
So what are the applications?
77
225340
2497
Hvad er anvendelsesmulighederne så?
03:59
I mean, many of you right now are probably going through your head.
78
227837
2448
Jeg mener, mange af jer går det sikkert igennem i jeres hoved lige nu.
04:02
Everyone that sees this gets excited, and says,
79
230285
1498
Alle der ser dette bliver begejstrede, og siger,
04:03
"Oh, I could use it for this and this and this."
80
231783
1929
"Åh, jeg kunne bruge det til det og det og det."
04:05
The applications in a general sense
81
233712
2062
Overordnet set kan anvendelsesmulighederne
04:07
could be anything that's anti-wetting.
82
235774
2830
være hvad som helst der er anti-befugtende.
04:10
We've certainly seen that today.
83
238604
2265
Det har vi bestemt set her i dag.
04:12
It could be anything that's anti-icing,
84
240869
2584
Det kan være hvad som helst der er anti-frysende,
04:15
because if you don't have water, you don't have ice.
85
243453
3455
fordi hvis der ikke er vand, er der ikke is.
04:18
It could be anti-corrosion.
86
246908
2272
Det kunne være anti-korroderende.
04:21
No water, no corrosion.
87
249180
2026
Ingen vand, ingen korrosion.
04:23
It could be anti-bacterial.
88
251206
2198
Det kunne være anti-bakteriel brug.
04:25
Without water, the bacteria won't survive.
89
253404
2709
Uden vand kan bakterier ikke overleve.
04:28
And it could be things that need to be self-cleaning as well.
90
256113
3819
Og det kunne være ting der også har brug for at være selvrensende.
04:33
So imagine how something like this
91
261629
3872
Forestil jer hvordan noget som dette
04:37
could help revolutionize your field of work.
92
265501
4121
kunne hjælpe med at revolutionere jeres arbejdsområde.
04:41
And I'm going to leave you with one last demonstration,
93
269622
2399
Og jeg vil efterlade jer med en sidste demonstration,
04:44
but before I do that, I would like to say thank you,
94
272021
2601
men inden jeg gør det, vil jeg gerne sige tak,
04:46
and think small.
95
274622
2043
og tænk småt.
04:57
(Applause)
96
285098
7548
(Bifald)
05:04
It's going to happen. Wait for it. Wait for it.
97
292646
4389
Det kommer til at ske. Vent på det. Vent på det.
05:09
Chris Anderson: You guys didn't hear about us cutting out the Design from TED? (Laughter)
98
297035
4782
Chris Anderson: I har ikke hørt noget om at vi har skåret Design væk fra TED? (Latter)
05:13
[Two minutes later...]

[To minutter senere …]
05:15
He ran into all sorts of problems in terms of managing the medical research part.
100
303567
2684
... han løb ind i alle mulige problem med hensyn til at lede den medicinske forskningsdel.
05:18
It's happening!
101
306251
2563
Det sker!

ABOUT THE SPEAKER
Mark Shaw - MacroencapsulatorMark Shaw develops technologies to contain hazardous waste, storm water and radioactives.
Why you should listen
On graduating from college, Mark Shaw saw a news broadcast on a toxic waste clean-up called Love Canal. The footage showed leaking steel drums of toxic waste being lowered into larger steel drums. It was then he was inspired to “save the world from toxic waste” and build a drum that would never leak. At 23, an economics major working out of a rented storage locker, he developed his first patent, an overpack container with resistance wiring built into the lid that would automatically heat-weld the lid to the container with the push of a button. He dubbed it “Macroencapsulation” and today, it is not only an EPA-approved treatment for hazardous waste but is also used extensively at the U.S. Department of Energy National Labs for shipping and treating mixed radioactive waste that is both chemically and radioactively hazardous. Many of his inventions and products have become the market standard worldwide. Shaw and his companies are also pioneers in the spill containment, stormwater management and spill response industries and are now bringing over 500 practical and innovative products and technologies to industry on a global basis through its 1,500 distributors covering 40 countries.
