ABOUT THE SPEAKER
Justin Hall-Tipping - Science entrepreneur
Justin Hall-Tipping works on nano-energy startups -- mastering the electron to create power.

Why you should listen

Some of our most serious planetary worries revolve around energy and power -- controlling it, paying for it, and the consequences of burning it. Justin Hall-Tipping had an epiphany about energy after seeing footage of a chunk of ice the size of his home state (Connecticut) falling off Antarctica into the ocean, and decided to focus on science to find new forms of energy. A longtime investor, he formed Nanoholdings  to work closely with universities and labs who are studying new forms of nano-scale energy in the four sectors of the energy economy: generation, transmission, storage and conservation.

Nanotech as a field is still very young (the National Science Foundation says it's "at a level of development similar to that of computer technology in the 1950s") and nano-energy in particular holds tremendous promise.

He says: "For the first time in human history, we actually have the ability to pick up an atom and place it the way we want. Some very powerful things can happen when you can do that."

Why can't we solve these problems?
0
1000
5000
00:21
We know what they are.
1
6000
3000
00:24
Something always seems to stop us.
2
9000
4000
00:28
Why?
3
13000
3000
00:31
I remember March the 15th, 2000.
4
16000
4000
00:35
The B15 iceberg broke off the Ross Ice Shelf.
5
20000
4000
00:39
In the newspaper it said
6
24000
3000
00:42
"it was all part of a normal process."
7
27000
3000
00:45
A little bit further on in the article
8
30000
3000
00:48
it said "a loss that would normally take
9
33000
3000
00:51
the ice shelf 50-100 years to replace."
10
36000
5000
00:58
That same word, "normal,"
11
43000
3000
01:01
had two different,
12
46000
2000
01:03
almost opposite meanings.
13
48000
3000
01:06
If we walk into the B15 iceberg
14
51000
3000
01:09
when we leave here today,
15
54000
3000
01:12
we're going to bump into something
16
57000
3000
01:15
a thousand feet tall,
17
60000
2000
01:17
76 miles long,
18
62000
4000
01:21
17 miles wide,
19
66000
3000
01:24
and it's going to weigh two gigatons.
20
69000
3000
01:27
I'm sorry, there's nothing normal about this.
21
72000
3000
01:30
And yet I think it's this perspective of us
22
75000
3000
01:33
as humans to look at our world
23
78000
3000
01:36
through the lens of normal
24
81000
2000
01:38
is one of the forces
25
83000
2000
01:40
that stops us developing real solutions.
26
85000
4000
01:46
Only 90 days after this,
27
91000
3000
01:49
arguably the greatest discovery
28
94000
2000
01:51
of the last century occurred.
29
96000
2000
01:53
It was the sequencing for the first time
30
98000
2000
01:55
of the human genome.
31
100000
3000
01:58
This is the code that's in every single one
32
103000
4000
02:02
of our 50 trillion cells
33
107000
2000
02:04
that makes us who we are and what we are.
34
109000
4000
02:08
And if we just take one cell's worth
35
113000
2000
02:10
of this code and unwind it,
36
115000
3000
02:15
it's a meter long,
37
120000
4000
02:19
two nanometers thick.
38
124000
2000
02:21
Two nanometers is 20 atoms in thickness.
39
126000
4000
02:25
And I wondered,
40
130000
2000
02:27
what if the answer to some of our biggest problems
41
132000
3000
02:30
could be found in the smallest of places,
42
135000
3000
02:33
where the difference between what is
43
138000
2000
02:35
valuable and what is worthless
44
140000
2000
02:37
is merely the addition or subtraction
45
142000
2000
02:39
of a few atoms?
46
144000
2000
02:41
And what
47
146000
2000
02:43
if we could get exquisite control
48
148000
3000
02:46
over the essence of energy,
49
151000
2000
02:48
the electron?
50
153000
3000
02:51
So I started to go around the world
51
156000
2000
02:53
finding the best and brightest scientists
52
158000
2000
02:55
I could at universities
53
160000
2000
02:57
whose collective discoveries have the chance
54
162000
2000
02:59
to take us there,
55
164000
2000
03:01
and we formed a company to build
56
166000
2000
03:03
on their extraordinary ideas.
57
168000
2000
03:05
Six and a half years later,
58
170000
2000
03:07
a hundred and eighty researchers,
59
172000
2000
03:09
they have some amazing developments
60
174000
2000
03:11
in the lab,
61
176000
2000
03:13
and I will show you three of those today,
62
178000
2000
03:15
such that we can stop burning up our planet
63
180000
3000
03:18
and instead,
64
183000
2000
03:20
we can generate all the energy we need
65
185000
3000
03:23
right where we are,
66
188000
2000
03:25
cleanly, safely, and cheaply.
67
190000
3000
03:28
Think of the space that we spend
68
193000
2000
03:30
most of our time.
69
195000
2000
03:32
A tremendous amount of energy
70
197000
2000
03:34
is coming at us from the sun.
71
199000
2000
03:36
We like the light that comes into the room,
72
201000
2000
03:38
but in the middle of summer,
73
203000
2000
03:40
all that heat is coming into the room
74
205000
2000
03:42
that we're trying to keep cool.
75
207000
2000
03:44
In winter, exactly the opposite is happening.
76
209000
2000
03:46
We're trying to heat up
77
211000
1000
03:47
the space that we're in,
78
212000
2000
03:49
and all that is trying to get out through the window.
79
214000
2000
03:51
Wouldn't it be really great
80
216000
2000
03:55
if the window could flick back the heat
81
220000
2000
03:57
into the room if we needed it
82
222000
2000
03:59
or flick it away before it came in?
83
224000
2000
04:01
One of the materials that can do this
84
226000
2000
04:03
is a remarkable material, carbon,
85
228000
5000
04:08
that has changed its form in this incredibly beautiful reaction
86
233000
3000
04:11
where graphite is blasted by a vapor,
87
236000
4000
04:16
and when the vaporized carbon condenses,
88
241000
4000
04:20
it condenses back into a different form:
89
245000
3000
04:23
chickenwire rolled up.
90
248000
3000
04:26
But this chickenwire carbon,
91
251000
2000
04:28
called a carbon nanotube,
92
253000
2000
04:30
is a hundred thousand times smaller
93
255000
2000
04:32
than the width of one of your hairs.
94
257000
3000
04:35
It's a thousand times
95
260000
2000
04:37
more conductive than copper.
96
262000
2000
04:40
How is that possible?
97
265000
3000
04:45
One of the things about working at the nanoscale
98
270000
4000
04:49
is things look and act very differently.
99
274000
3000
04:52
You think of carbon as black.
100
277000
3000
04:58
Carbon at the nanoscale
101
283000
3000
05:01
is actually transparent
102
286000
3000
05:04
and flexible.
103
289000
3000
05:09
And when it's in this form,
104
294000
2000
05:11
if I combine it with a polymer
105
296000
3000
05:14
and affix it to your window
106
299000
3000
05:17
when it's in its colored state,
107
302000
3000
05:20
it will reflect away all heat and light,
108
305000
3000
05:23
and when it's in its bleached state
109
308000
2000
05:25
it will let all the light and heat through
110
310000
3000
05:28
and any combination in between.
111
313000
3000
05:31
To change its state, by the way,
112
316000
3000
05:34
takes two volts from a millisecond pulse.
113
319000
3000
05:37
And once you've changed its state, it stays there
114
322000
3000
05:40
until you change its state again.
115
325000
3000
05:43
As we were working on this incredible
116
328000
2000
05:45
discovery at University of Florida,
117
330000
2000
05:47
we were told to go down the corridor
118
332000
3000
05:50
to visit another scientist,
119
335000
2000
05:52
and he was working
120
337000
2000
05:54
on a pretty incredible thing.
121
339000
2000
05:56
Imagine
122
341000
2000
05:58
if we didn't have to rely
123
343000
2000
06:00
on artificial lighting to get around at night.
124
345000
4000
06:06
We'd have to see at night, right?
125
351000
4000
06:12
This lets you do it.
126
357000
2000
06:14
It's a nanomaterial, two nanomaterials,
127
359000
3000
06:17
a detector and an imager.
128
362000
3000
06:20
The total width of it
129
365000
2000
06:22
is 600 times smaller
130
367000
2000
06:24
than the width of a decimal place.
131
369000
3000
06:27
And it takes all the infrared available at night,
132
372000
4000
06:31
converts it into an electron
133
376000
3000
06:34
in the space of two small films,
134
379000
3000
06:37
and is enabling you to play an image
135
382000
3000
06:40
which you can see through.
136
385000
3000
06:47
I'm going to show to TEDsters,
137
392000
3000
06:50
the first time, this operating.
138
395000
2000
06:52
Firstly I'm going to show you
139
397000
2000
06:54
the transparency.
140
399000
3000
06:57
Transparency is key.
141
402000
4000
07:01
It's a film that you can look through.
142
406000
3000
07:04
And then I'm going to turn the lights out.
143
409000
3000
07:07
And you can see, off a tiny film,
144
412000
3000
07:10
incredible clarity.
145
415000
4000
07:14
As we were working on this, it dawned on us:
146
419000
4000
07:18
this is taking infrared radiation, wavelengths,
147
423000
4000
07:22
and converting it into electrons.
148
427000
3000
07:25
What if we combined it
149
430000
6000
07:31
with this?
150
436000
3000
07:34
Suddenly you've converted energy
151
439000
3000
07:37
into an electron on a plastic surface
152
442000
4000
07:41
that you can stick on your window.
153
446000
3000
07:44
But because it's flexible,
154
449000
2000
07:46
it can be on any surface whatsoever.
155
451000
4000
07:50
The power plant of tomorrow
156
455000
3000
07:53
is no power plant.
157
458000
7000
08:00
We talked about generating and using.
158
465000
3000
08:03
We want to talk about storing energy,
159
468000
2000
08:05
and unfortunately
160
470000
2000
08:07
the best thing we've got going
161
472000
2000
08:09
is something that was developed in France
162
474000
2000
08:11
a hundred and fifty years ago,
163
476000
2000
08:13
the lead acid battery.
164
478000
2000
08:15
In terms of dollars per what's stored,
165
480000
2000
08:17
it's simply the best.
166
482000
2000
08:19
Knowing that we're not going to put fifty of
167
484000
2000
08:21
these in our basements to store our power,
168
486000
2000
08:23
we went to a group at University of Texas at Dallas,
169
488000
2000
08:25
and we gave them this diagram.
170
490000
2000
08:27
It was in actually a diner
171
492000
2000
08:29
outside of Dallas/Fort Worth Airport.
172
494000
2000
08:31
We said, "Could you build this?"
173
496000
2000
08:33
And these scientists,
174
498000
2000
08:35
instead of laughing at us, said, "Yeah."
175
500000
2000
08:37
And what they built was eBox.
176
502000
3000
08:40
EBox is testing new nanomaterials
177
505000
2000
08:42
to park an electron on the outside,
178
507000
3000
08:45
hold it until you need it,
179
510000
3000
08:48
and then be able to release it and pass it off.
180
513000
3000
08:51
Being able to do that means
181
516000
4000
08:55
that I can generate energy
182
520000
3000
08:58
cleanly, efficiently and cheaply
183
523000
3000
09:01
right where I am.
184
526000
2000
09:03
It's my energy.
185
528000
3000
09:06
And if I don't need it, I can convert it
186
531000
2000
09:08
back up on the window
187
533000
2000
09:10
to energy, light, and beam it,
188
535000
2000
09:12
line of site, to your place.
189
537000
3000
09:15
And for that I do not need
190
540000
3000
09:18
an electric grid between us.
191
543000
3000
09:21
The grid of tomorrow is no grid,
192
546000
4000
09:25
and energy, clean efficient energy,
193
550000
4000
09:29
will one day be free.
194
554000
3000
09:36
If you do this, you get the last puzzle piece,
195
561000
4000
09:40
which is water.
196
565000
3000
09:46
Each of us, every day,
197
571000
5000
09:51
need just eight glasses of this,
198
576000
5000
09:56
because we're human.
199
581000
3000
09:59
When we run out of water,
200
584000
2000
10:01
as we are in some parts of the world
201
586000
2000
10:03
and soon to be in other parts of the world,
202
588000
2000
10:05
we're going to have to get this from the sea,
203
590000
3000
10:08
and that's going to require us to build desalination plants.
204
593000
3000
10:11
19 trillion dollars is what we're going to have to spend.
205
596000
3000
10:14
These also require tremendous amounts of energy.
206
599000
2000
10:16
In fact, it's going to require twice the world's
207
601000
2000
10:18
supply of oil to run the pumps
208
603000
2000
10:20
to generate the water.
209
605000
3000
10:23
We're simply not going to do that.
210
608000
2000
10:25
But in a world where energy is freed
211
610000
2000
10:27
and transmittable
212
612000
2000
10:29
easily and cheaply, we can take any water
213
614000
2000
10:31
wherever we are
214
616000
2000
10:33
and turn it into whatever we need.
215
618000
4000
10:37
I'm glad to be working with
216
622000
2000
10:39
incredibly brilliant and kind scientists,
217
624000
2000
10:41
no kinder than
218
626000
2000
10:43
many of the people in the world,
219
628000
2000
10:45
but they have a magic look at the world.
220
630000
3000
10:48
And I'm glad to see their discoveries
221
633000
2000
10:50
coming out of the lab and into the world.
222
635000
3000
10:53
It's been a long time in coming for me.
223
638000
4000
10:57
18 years ago,
224
642000
3000
11:00
I saw a photograph in the paper.
225
645000
4000
11:04
It was taken by Kevin Carter
226
649000
2000
11:06
who went to the Sudan
227
651000
2000
11:08
to document their famine there.
228
653000
2000
11:10
I've carried this photograph with me
229
655000
2000
11:12
every day since then.
230
657000
2000
11:17
It's a picture of a little girl dying of thirst.
231
662000
5000
11:27
By any standard this is wrong.
232
672000
5000
11:32
It's just wrong.
233
677000
3000
11:38
We can do better than this.
234
683000
3000
11:41
We should do better than this.
235
686000
3000
11:44
And whenever I go round
236
689000
2000
11:46
to somebody who says,
237
691000
2000
11:48
"You know what, you're working on something that's too difficult.
238
693000
2000
11:50
It'll never happen. You don't have enough money.
239
695000
3000
11:53
You don't have enough time.
240
698000
3000
11:56
There's something much more interesting around the corner,"
241
701000
3000
11:59
I say, "Try saying that to her."
242
704000
2000
12:01
That's what I say in my mind. And I just say
243
706000
2000
12:03
"thank you," and I go on to the next one.
244
708000
3000
12:06
This is why we have to solve our problems,
245
711000
3000
12:09
and I know the answer as to how
246
714000
5000
12:14
is to be able to get exquisite control
247
719000
4000
12:18
over a building block of nature,
248
723000
3000
12:21
the stuff of life:
249
726000
2000
12:23
the simple electron.
250
728000
2000
12:25
Thank you.
251
730000
2000
12:27
(Applause)

ABOUT THE SPEAKER
Justin Hall-Tipping - Science entrepreneur
Justin Hall-Tipping works on nano-energy startups -- mastering the electron to create power.

Why you should listen

Some of our most serious planetary worries revolve around energy and power -- controlling it, paying for it, and the consequences of burning it. Justin Hall-Tipping had an epiphany about energy after seeing footage of a chunk of ice the size of his home state (Connecticut) falling off Antarctica into the ocean, and decided to focus on science to find new forms of energy. A longtime investor, he formed Nanoholdings  to work closely with universities and labs who are studying new forms of nano-scale energy in the four sectors of the energy economy: generation, transmission, storage and conservation.

Nanotech as a field is still very young (the National Science Foundation says it's "at a level of development similar to that of computer technology in the 1950s") and nano-energy in particular holds tremendous promise.

He says: "For the first time in human history, we actually have the ability to pick up an atom and place it the way we want. Some very powerful things can happen when you can do that."
