1
00:00:01,713 --> 00:00:03,079
Can I get a show of hands --

2
00:00:03,103 --> 00:00:06,805
how many of you in this room
have been on a plane in this past year?

3
00:00:08,258 --> 00:00:09,411
That's pretty good.

4
00:00:09,435 --> 00:00:12,320
Well, it turns out that you
share that experience

5
00:00:12,344 --> 00:00:15,179
with more than three billion
people every year.

6
00:00:15,203 --> 00:00:18,340
And when we put so many people
in all these metal tubes

7
00:00:18,364 --> 00:00:19,950
that fly all over the world,

8
00:00:19,974 --> 00:00:22,647
sometimes, things like this can happen

9
00:00:22,671 --> 00:00:24,558
and you get a disease epidemic.

10
00:00:25,116 --> 00:00:27,067
I first actually got into this topic

11
00:00:27,091 --> 00:00:29,723
when I heard about the Ebola
outbreak last year.

12
00:00:29,747 --> 00:00:31,207
And it turns out that,

13
00:00:31,231 --> 00:00:34,061
although Ebola spreads
through these more range-limited,

14
00:00:34,085 --> 00:00:35,419
large-droplet routes,

15
00:00:35,443 --> 00:00:37,421
there's all these other sorts of diseases

16
00:00:37,445 --> 00:00:39,421
that can be spread in the airplane cabin.

17
00:00:39,445 --> 00:00:42,629
The worst part is, when we take
a look at some of the numbers,

18
00:00:42,653 --> 00:00:44,066
it's pretty scary.

19
00:00:44,090 --> 00:00:45,850
So with H1N1,

20
00:00:45,874 --> 00:00:48,263
there was this guy that decided
to go on the plane

21
00:00:48,287 --> 00:00:50,058
and in the matter of a single flight

22
00:00:50,082 --> 00:00:52,336
actually spread the disease
to 17 other people.

23
00:00:52,360 --> 00:00:54,488
And then there was this
other guy with SARS,

24
00:00:54,512 --> 00:00:56,614
who managed to go on a three-hour flight

25
00:00:56,638 --> 00:00:59,480
and spread the disease to 22 other people.

26
00:00:59,504 --> 00:01:02,912
That's not exactly my idea
of a great superpower.

27
00:01:03,658 --> 00:01:06,222
When we take a look at this,
what we also find

28
00:01:06,246 --> 00:01:09,222
is that it's very difficult
to pre-screen for these diseases.

29
00:01:09,619 --> 00:01:11,710
So when someone actually
goes on a plane,

30
00:01:11,734 --> 00:01:12,940
they could be sick

31
00:01:12,964 --> 00:01:15,359
and they could actually
be in this latency period

32
00:01:15,383 --> 00:01:17,542
in which they could actually
have the disease

33
00:01:17,566 --> 00:01:19,138
but not exhibit any symptoms,

34
00:01:19,162 --> 00:01:21,353
and they could, in turn,
spread the disease

35
00:01:21,377 --> 00:01:23,050
to many other people in the cabin.

36
00:01:23,074 --> 00:01:25,156
How that actually works is that right now

37
00:01:25,180 --> 00:01:27,466
we've got air coming in
from the top of the cabin

38
00:01:27,490 --> 00:01:29,916
and from the side of the cabin,
as you see in blue.

39
00:01:29,940 --> 00:01:34,142
And then also, that air goes out
through these very efficient filters

40
00:01:34,166 --> 00:01:38,714
that eliminate 99.97 percent
of pathogens near the outlets.

41
00:01:39,444 --> 00:01:40,921
What happens right now, though,

42
00:01:40,945 --> 00:01:43,012
is that we have this
mixing airflow pattern.

43
00:01:43,036 --> 00:01:44,868
So if someone were to actually sneeze,

44
00:01:44,892 --> 00:01:47,596
that air would get swirled
around multiple times

45
00:01:47,620 --> 00:01:50,865
before it even has a chance
to go out through the filter.

46
00:01:51,785 --> 00:01:54,998
So I thought: clearly, this
is a pretty serious problem.

47
00:01:55,022 --> 00:01:58,755
I didn't have the money
to go out and buy a plane,

48
00:01:58,779 --> 00:02:01,017
so I decided to build a computer instead.

49
00:02:01,041 --> 00:02:04,313
It actually turns out that
with computational fluid dynamics,

50
00:02:04,337 --> 00:02:06,938
what we're able to do
is create these simulations

51
00:02:06,962 --> 00:02:08,756
that give us higher resolutions

52
00:02:08,780 --> 00:02:12,400
than actually physically going
in and taking readings in the plane.

53
00:02:12,836 --> 00:02:15,850
And so how, essentially, this works
is you would start out

54
00:02:15,874 --> 00:02:17,546
with these 2D drawings --

55
00:02:17,570 --> 00:02:20,698
these are floating around
in technical papers around the Internet.

56
00:02:20,722 --> 00:02:23,615
I take that and then I put it
into this 3D-modeling software,

57
00:02:23,639 --> 00:02:25,418
really building that 3D model.

58
00:02:25,442 --> 00:02:29,901
And then I divide that model
that I just built into these tiny pieces,

59
00:02:29,925 --> 00:02:33,502
essentially meshing it so that
the computer can better understand it.

60
00:02:33,526 --> 00:02:37,247
And then I tell the computer where
the air goes in and out of the cabin,

61
00:02:37,271 --> 00:02:38,770
throw in a bunch of physics

62
00:02:38,794 --> 00:02:43,015
and basically sit there and wait until
the computer calculates the simulation.

63
00:02:44,015 --> 00:02:47,642
So what we get, actually,
with the conventional cabin is this:

64
00:02:47,666 --> 00:02:49,913
you'll notice the middle person sneezing,

65
00:02:50,767 --> 00:02:54,159
and we go "Splat!" -- it goes
right into people's faces.

66
00:02:54,882 --> 00:02:56,703
It's pretty disgusting.

67
00:02:56,727 --> 00:02:59,075
From the front, you'll notice
those two passengers

68
00:02:59,099 --> 00:03:00,885
sitting next to the central passenger

69
00:03:00,909 --> 00:03:02,615
not exactly having a great time.

70
00:03:02,639 --> 00:03:04,825
And when we take a look
at that from the side,

71
00:03:04,849 --> 00:03:08,842
you'll also notice those pathogens
spreading across the length of the cabin.

72
00:03:10,017 --> 00:03:12,367
The first thing I thought was,
"This is no good."

73
00:03:12,391 --> 00:03:15,899
So I actually conducted
more than 32 different simulations

74
00:03:15,923 --> 00:03:19,288
and ultimately, I came up
with this solution right here.

75
00:03:19,312 --> 00:03:22,828
This is what I call a -- patent pending --
Global Inlet Director.

76
00:03:22,852 --> 00:03:25,418
With this, we're able to reduce
pathogen transmission

77
00:03:25,442 --> 00:03:27,210
by about 55 times,

78
00:03:27,234 --> 00:03:30,387
and increase fresh-air inhalation
by about 190 percent.

79
00:03:30,411 --> 00:03:32,015
So how this actually works

80
00:03:32,039 --> 00:03:35,168
is we would install this piece
of composite material

81
00:03:35,192 --> 00:03:38,160
into these existing spots
that are already in the plane.

82
00:03:38,184 --> 00:03:40,185
So it's very cost-effective to install

83
00:03:40,209 --> 00:03:42,057
and we can do this directly overnight.

84
00:03:42,081 --> 00:03:45,629
All we have to do is put a couple
of screws in there and you're good to go.

85
00:03:45,653 --> 00:03:48,512
And the results that we get
are absolutely amazing.

86
00:03:48,536 --> 00:03:52,072
Instead of having those problematic
swirling airflow patterns,

87
00:03:52,096 --> 00:03:53,838
we can create these walls of air

88
00:03:53,862 --> 00:03:56,032
that come down in-between the passengers

89
00:03:56,056 --> 00:03:57,954
to create personalized breathing zones.

90
00:03:57,978 --> 00:04:00,963
So you'll notice the middle passenger
here is sneezing again,

91
00:04:00,987 --> 00:04:03,700
but this time, we're able
to effectively push that down

92
00:04:03,724 --> 00:04:06,437
to the filters for elimination.

93
00:04:06,461 --> 00:04:07,857
And same thing from the side,

94
00:04:07,881 --> 00:04:11,110
you'll notice we're able to directly
push those pathogens down.

95
00:04:11,682 --> 00:04:15,176
So if you take a look again now
at the same scenario

96
00:04:15,200 --> 00:04:16,889
but with this innovation installed,

97
00:04:16,913 --> 00:04:18,929
you'll notice the middle
passenger sneezes,

98
00:04:18,953 --> 00:04:22,026
and this time, we're pushing
that straight down into the outlet

99
00:04:22,050 --> 00:04:25,771
before it gets a chance
to infect any other people.

100
00:04:25,795 --> 00:04:28,919
So you'll notice the two passengers
sitting next to the middle guy

101
00:04:28,943 --> 00:04:31,176
are breathing virtually
no pathogens at all.

102
00:04:31,200 --> 00:04:33,728
Take a look at that from the side as well,

103
00:04:33,752 --> 00:04:35,307
you see a very efficient system.

104
00:04:35,331 --> 00:04:37,953
And in short, with this system, we win.

105
00:04:39,255 --> 00:04:42,144
When we take a look at what this means,

106
00:04:42,168 --> 00:04:45,640
what we see is that this not only works
if the middle passenger sneezes,

107
00:04:45,664 --> 00:04:48,438
but also if the window-seat
passenger sneezes

108
00:04:48,462 --> 00:04:50,557
or if the aisle-seat passenger sneezes.

109
00:04:51,167 --> 00:04:54,254
And so with this solution, what does
this mean for the world?

110
00:04:54,278 --> 00:04:57,792
Well, when we take a look at this

111
00:04:57,816 --> 00:05:00,385
from the computer simulation
into real life,

112
00:05:00,409 --> 00:05:03,171
we can see with this 3D model
that I built over here,

113
00:05:03,195 --> 00:05:05,283
essentially using 3D printing,

114
00:05:05,307 --> 00:05:08,266
we can see those same
airflow patterns coming down,

115
00:05:08,290 --> 00:05:09,876
right to the passengers.

116
00:05:10,920 --> 00:05:13,990
In the past, the SARS epidemic
actually cost the world

117
00:05:14,014 --> 00:05:15,943
about 40 billion dollars.

118
00:05:15,967 --> 00:05:17,126
And in the future,

119
00:05:17,150 --> 00:05:19,696
a big disease outbreak
could actually cost the world

120
00:05:19,720 --> 00:05:21,578
in excess of three trillion dollars.

121
00:05:21,942 --> 00:05:25,419
So before, it used to be that you had
to take an airplane out of service

122
00:05:25,443 --> 00:05:27,315
for one to two months,

123
00:05:27,339 --> 00:05:30,911
spend tens of thousands of man hours
and several million dollars

124
00:05:30,935 --> 00:05:32,258
to try to change something.

125
00:05:32,282 --> 00:05:35,793
But now, we're able to install
something essentially overnight

126
00:05:35,817 --> 00:05:37,544
and see results right away.

127
00:05:37,568 --> 00:05:40,774
So it's really now a matter of taking
this through to certification,

128
00:05:40,798 --> 00:05:41,988
flight testing,

129
00:05:42,012 --> 00:05:45,004
and going through all of these
regulatory approvals processes.

130
00:05:45,028 --> 00:05:48,092
But it just really goes to show
that sometimes the best solutions

131
00:05:48,116 --> 00:05:49,554
are the simplest solutions.

132
00:05:49,935 --> 00:05:53,125
And two years ago, even,

133
00:05:53,149 --> 00:05:54,918
this project would not have happened,

134
00:05:54,942 --> 00:05:57,768
just because the technology then
wouldn't have supported it.

135
00:05:57,792 --> 00:06:00,261
But now with advanced computing

136
00:06:00,285 --> 00:06:02,471
and how developed our Internet is,

137
00:06:02,495 --> 00:06:05,134
it's really the golden era for innovation.

138
00:06:05,158 --> 00:06:08,401
And so the question I ask all
of you today is: why wait?

139
00:06:08,425 --> 00:06:10,746
Together, we can build the future today.

140
00:06:11,123 --> 00:06:12,274
Thanks.

141
00:06:12,298 --> 00:06:15,404
(Applause)
