If I could reveal anything
0
0
4000
00:22
that is hidden from us,
1
4000
2000
00:24
at least in modern cultures,
2
6000
4000
00:28
it would be to reveal something that we've forgotten,
3
10000
4000
00:32
that we used to know
4
14000
2000
00:34
as well as we knew our own names.
5
16000
4000
00:38
And that is that we live in a competent universe,
6
20000
4000
00:42
that we are part of a brilliant planet,
7
24000
3000
00:45
and that we are surrounded by genius.
8
27000
4000
00:49
Biomimicry is a new discipline
9
31000
3000
00:52
that tries to learn from those geniuses,
10
34000
2000
00:54
and take advice from them, design advice.
11
36000
4000
00:58
That's where I live,
12
40000
3000
01:01
and it's my university as well.
13
43000
3000
01:04
I'm surrounded by genius. I cannot help but
14
46000
4000
01:08
remember the organisms and the ecosystems
15
50000
5000
01:13
that know how to live here gracefully on this planet.
16
55000
5000
01:18
This is what I would tell you to remember
17
60000
2000
01:20
if you ever forget this again.
18
62000
3000
01:23
Remember this.
19
65000
2000
01:25
This is what happens every year.
20
67000
4000
01:29
This is what keeps its promise.
21
71000
3000
01:32
While we're doing bailouts, this is what happened.
22
74000
3000
01:35
Spring.
23
77000
2000
01:37
Imagine designing spring.
24
79000
5000
01:42
Imagine that orchestration.
25
84000
2000
01:44
You think TED is hard to organize. (Laughter) Right?
26
86000
4000
01:48
Imagine, and if you haven't done this in a while, do.
27
90000
5000
01:53
Imagine the timing, the coordination,
28
95000
4000
01:57
all without top-down laws,
29
99000
4000
02:01
or policies, or climate change protocols.
30
103000
3000
02:04
This happens every year.
31
106000
3000
02:07
There is lots of showing off.
32
109000
4000
02:11
There is lots of love in the air.
33
113000
5000
02:16
There's lots of grand openings.
34
118000
5000
02:21
And the organisms, I promise you,
35
123000
2000
02:23
have all of their priorities in order.
36
125000
4000
02:27
I have this neighbor that keeps me in touch with this,
37
129000
4000
02:31
because he's living, usually on his back,
38
133000
2000
02:33
looking up at those grasses.
39
135000
3000
02:36
And one time he came up to me --
40
138000
2000
02:38
he was about seven or eight years old -- he came up to me.
41
140000
2000
02:40
And there was a wasp's nest
42
142000
2000
02:42
that I had let grow in my yard,
43
144000
2000
02:44
right outside my door.
44
146000
3000
02:47
And most people knock them down when they're small.
45
149000
2000
02:49
But it was fascinating to me,
46
151000
2000
02:51
because I was looking at this sort of fine Italian end papers.
47
153000
3000
02:54
And he came up to me and he knocked.
48
156000
2000
02:56
He would come every day with something to show me.
49
158000
3000
02:59
And like, knock like a woodpecker on my door until I opened it up.
50
161000
3000
03:02
And he asked me
51
164000
4000
03:06
how I had made the house for those wasps,
52
168000
7000
03:13
because he had never seen one this big.
53
175000
3000
03:16
And I told him, "You know, Cody,
54
178000
3000
03:19
the wasps actually made that."
55
181000
2000
03:21
And we looked at it together.
56
183000
2000
03:23
And I could see why he thought,
57
185000
4000
03:27
you know -- it was so beautifully done.
58
189000
2000
03:29
It was so architectural. It was so precise.
59
191000
3000
03:32
But it occurred to me, how in his small life
60
194000
4000
03:36
had he already believed the myth
61
198000
4000
03:40
that if something was that well done,
62
202000
4000
03:44
that we must have done it.
63
206000
2000
03:46
How did he not know --
64
208000
3000
03:49
it's what we've all forgotten --
65
211000
3000
03:52
that we're not the first ones to build.
66
214000
3000
03:55
We're not the first ones to process cellulose.
67
217000
3000
03:58
We're not the first ones to make paper. We're not the first ones
68
220000
2000
04:00
to try to optimize packing space,
69
222000
3000
04:03
or to waterproof, or to try to heat and cool a structure.
70
225000
3000
04:06
We're not the first ones to build houses for our young.
71
228000
6000
04:12
What's happening now, in this field called biomimicry,
72
234000
4000
04:16
is that people are beginning to remember
73
238000
3000
04:19
that organisms, other organisms,
74
241000
4000
04:23
the rest of the natural world,
75
245000
2000
04:25
are doing things very similar to what we need to do.
76
247000
4000
04:29
But in fact they are doing them in a way
77
251000
2000
04:31
that have allowed them to live gracefully on this planet
78
253000
2000
04:33
for billions of years.
79
255000
3000
04:36
So these people, biomimics,
80
258000
3000
04:39
are nature's apprentices.
81
261000
2000
04:41
And they're focusing on function.
82
263000
2000
04:43
What I'd like to do is show you a few of the things
83
265000
3000
04:46
that they're learning.
84
268000
3000
04:49
They have asked themselves,
85
271000
2000
04:51
"What if, every time I started to invent something,
86
273000
4000
04:55
I asked, 'How would nature solve this?'"
87
277000
3000
04:58
And here is what they're learning.
88
280000
2000
05:00
This is an amazing picture from a Czech photographer named Jack Hedley.
89
282000
3000
05:03
This is a story about an engineer at J.R. West.
90
285000
3000
05:06
They're the people who make the bullet train.
91
288000
2000
05:08
It was called the bullet train
92
290000
2000
05:10
because it was rounded in front,
93
292000
2000
05:12
but every time it went into a tunnel
94
294000
2000
05:14
it would build up a pressure wave,
95
296000
2000
05:16
and then it would create like a sonic boom when it exited.
96
298000
3000
05:19
So the engineer's boss said,
97
301000
2000
05:21
"Find a way to quiet this train."
98
303000
3000
05:24
He happened to be a birder.
99
306000
2000
05:26
He went to the equivalent of an Audubon Society meeting.
100
308000
4000
05:30
And he studied -- there was a film about king fishers.
101
312000
2000
05:32
And he thought to himself, "They go from one density of medium,
102
314000
3000
05:35
the air, into another density of medium, water,
103
317000
3000
05:38
without a splash. Look at this picture.
104
320000
3000
05:41
Without a splash, so they can see the fish.
105
323000
3000
05:44
And he thought, "What if we do this?"
106
326000
3000
05:47
Quieted the train.
107
329000
3000
05:50
Made it go 10 percent faster on 15 percent less electricity.
108
332000
5000
05:55
How does nature repel bacteria?
109
337000
2000
05:57
We're not the first ones to have to protect ourselves
110
339000
3000
06:00
from some bacteria.
111
342000
2000
06:02
Turns out that -- this is a Galapagos Shark.
112
344000
4000
06:06
It has no bacteria on its surface, no fouling on its surface, no barnacles.
113
348000
5000
06:11
And it's not because it goes fast.
114
353000
2000
06:13
It actually basks. It's a slow-moving shark.
115
355000
3000
06:16
So how does it keep its body free of bacteria build-up?
116
358000
3000
06:19
It doesn't do it with a chemical.
117
361000
2000
06:21
It does it, it turns out, with the same denticles
118
363000
2000
06:23
that you had on Speedo bathing suits,
119
365000
4000
06:27
that broke all those records in the Olympics,
120
369000
2000
06:29
but it's a particular kind of pattern.
121
371000
2000
06:31
And that pattern, the architecture of that pattern
122
373000
3000
06:34
on its skin denticles
123
376000
3000
06:37
keep bacteria from being able to land and adhere.
124
379000
4000
06:41
There is a company called Sharklet Technologies
125
383000
2000
06:43
that's now putting this on the surfaces in hospitals
126
385000
4000
06:47
to keep bacteria from landing,
127
389000
2000
06:49
which is better than dousing it with anti-bacterials or harsh cleansers
128
391000
6000
06:55
that many, many organisms are now becoming drug resistant.
129
397000
4000
06:59
Hospital-acquired infections are now killing
130
401000
2000
07:01
more people every year in the United States
131
403000
3000
07:04
than die from AIDS or cancer or car accidents combined --
132
406000
5000
07:09
about 100,000.
133
411000
2000
07:11
This is a little critter that's in the Namibian desert.
134
413000
3000
07:14
It has no fresh water that it's able to drink,
135
416000
3000
07:17
but it drinks water out of fog.
136
419000
3000
07:20
It's got bumps on the back of its wing covers.
137
422000
3000
07:23
And those bumps act like a magnet for water.
138
425000
3000
07:26
They have water-loving tips, and waxy sides.
139
428000
3000
07:29
And the fog comes in and it builds up on the tips.
140
431000
3000
07:32
And it goes down the sides and goes into the critter's mouth.
141
434000
3000
07:35
There is actually a scientist here at Oxford
142
437000
3000
07:38
who studied this, Andrew Parker.
143
440000
2000
07:40
And now kinetic and architectural firms like Grimshaw
144
442000
4000
07:44
are starting to look at this as a way
145
446000
2000
07:46
of coating buildings
146
448000
3000
07:49
so that they gather water from the fog.
147
451000
2000
07:51
10 times better than our fog-catching nets.
148
453000
5000
07:56
CO2 as a building block.
149
458000
2000
07:58
Organisms don't think of CO2 as a poison.
150
460000
3000
08:01
Plants and organisms that make shells,
151
463000
2000
08:03
coral, think of it as a building block.
152
465000
3000
08:06
There is now a cement manufacturing company
153
468000
3000
08:09
starting in the United States called Calera.
154
471000
3000
08:12
They've borrowed the recipe from the coral reef,
155
474000
3000
08:15
and they're using CO2 as a building block
156
477000
3000
08:18
in cement, in concrete.
157
480000
2000
08:20
Instead of -- cement usually
158
482000
2000
08:22
emits a ton of CO2 for every ton of cement.
159
484000
3000
08:25
Now it's reversing that equation,
160
487000
2000
08:27
and actually sequestering half a ton of CO2
161
489000
3000
08:30
thanks to the recipe from the coral.
162
492000
2000
08:32
None of these are using the organisms.
163
494000
2000
08:34
They're really only using the blueprints or the recipes
164
496000
2000
08:36
from the organisms.
165
498000
3000
08:39
How does nature gather the sun's energy?
166
501000
3000
08:42
This is a new kind of solar cell
167
504000
2000
08:44
that's based on how a leaf works.
168
506000
2000
08:46
It's self-assembling.
169
508000
2000
08:48
It can be put down on any substrate whatsoever.
170
510000
2000
08:50
It's extremely inexpensive
171
512000
2000
08:52
and rechargeable every five years.
172
514000
3000
08:55
It's actually a company a company that I'm involved in called OneSun,
173
517000
3000
08:58
with Paul Hawken.
174
520000
2000
09:00
There are many many ways that nature filters water
175
522000
4000
09:04
that takes salt out of water.
176
526000
3000
09:07
We take water and push it against a membrane.
177
529000
3000
09:10
And then we wonder why the membrane clogs
178
532000
2000
09:12
and why it takes so much electricity.
179
534000
2000
09:14
Nature does something much more elegant.
180
536000
2000
09:16
And it's in every cell.
181
538000
2000
09:18
Every red blood cell of your body right now
182
540000
3000
09:21
has these hourglass-shaped pores
183
543000
2000
09:23
called aquaporins.
184
545000
2000
09:25
They actually export water molecules through.
185
547000
3000
09:28
It's kind of a forward osmosis.
186
550000
2000
09:30
They export water molecules through,
187
552000
2000
09:32
and leave solutes on the other side.
188
554000
3000
09:35
A company called Aquaporin is starting to make desalination
189
557000
3000
09:38
membranes mimicking this technology.
190
560000
4000
09:42
Trees and bones are constantly reforming themselves
191
564000
5000
09:47
along lines of stress.
192
569000
2000
09:49
This algorithm has been put into a software program
193
571000
4000
09:53
that's now being used to make bridges lightweight,
194
575000
2000
09:55
to make building beams lightweight.
195
577000
3000
09:58
Actually G.M. Opel used it
196
580000
2000
10:00
to create that skeleton you see,
197
582000
4000
10:04
in what's called their bionic car.
198
586000
3000
10:07
It lightweighted that skeleton using a minimum amount of material,
199
589000
3000
10:10
as an organism must,
200
592000
3000
10:13
for the maximum amount of strength.
201
595000
4000
10:17
This beetle, unlike this chip bag here,
202
599000
4000
10:21
this beetle uses one material, chitin.
203
603000
3000
10:24
And it finds many many ways
204
606000
2000
10:26
to put many functions into it.
205
608000
2000
10:28
It's waterproof.
206
610000
2000
10:30
It's strong and resilient.
207
612000
2000
10:32
It's breathable. It creates color through structure.
208
614000
4000
10:36
Whereas that chip bag has about seven layers to do all of those things.
209
618000
4000
10:40
One of our major inventions
210
622000
3000
10:43
that we need to be able to do
211
625000
2000
10:45
to come even close to what these organisms can do
212
627000
2000
10:47
is to find a way
213
629000
4000
10:51
to minimize the amount of material, the kind of material we use,
214
633000
3000
10:54
and to add design to it.
215
636000
2000
10:56
We use five polymers in the natural world
216
638000
3000
10:59
to do everything that you see.
217
641000
2000
11:01
In our world we use about 350 polymers
218
643000
4000
11:05
to make all this.
219
647000
5000
11:10
Nature is nano.
220
652000
2000
11:12
Nanotechnology, nanoparticles, you hear a lot of worry about this.
221
654000
5000
11:17
Loose nanoparticles. What is really interesting to me
222
659000
4000
11:21
is that not many people have been asking,
223
663000
3000
11:24
"How can we consult nature about how to make nanotechnology safe?"
224
666000
5000
11:29
Nature has been doing that for a long time.
225
671000
2000
11:31
Embedding nanoparticles in a material for instance, always.
226
673000
4000
11:35
In fact, sulfur-reducing bacteria,
227
677000
2000
11:37
as part of their synthesis,
228
679000
3000
11:40
they will emit, as a byproduct,
229
682000
2000
11:42
nanoparticles into the water.
230
684000
2000
11:44
But then right after that, they emit a protein
231
686000
2000
11:46
that actually gathers and aggregates those nanoparticles
232
688000
3000
11:49
so that they fall out of solution.
233
691000
5000
11:54
Energy use. Organisms sip energy,
234
696000
5000
11:59
because they have to work or barter for every single bit that they get.
235
701000
5000
12:04
And one of the largest fields right now,
236
706000
3000
12:07
in the world of energy grids,
237
709000
2000
12:09
you hear about the smart grid.
238
711000
2000
12:11
One of the largest consultants are the social insects.
239
713000
4000
12:15
Swarm technology. There is a company called Regen.
240
717000
3000
12:18
They are looking at how ants and bees
241
720000
3000
12:21
find their food and their flowers
242
723000
3000
12:24
in the most effective way
243
726000
2000
12:26
as a whole hive.
244
728000
2000
12:28
And they're having appliances in your home
245
730000
3000
12:31
talk to one another through that algorithm,
246
733000
3000
12:34
and determine how to minimize peak power use.
247
736000
6000
12:40
There's a group of scientists in Cornell
248
742000
3000
12:43
that are making what they call a synthetic tree,
249
745000
2000
12:45
because they are saying, "There is no pump at the bottom of a tree."
250
747000
4000
12:49
It's capillary action and transpiration pulls
251
751000
4000
12:53
water up, a drop at a time,
252
755000
2000
12:55
pulling it, releasing it from a leaf and pulling it up through the roots.
253
757000
5000
13:00
And they're creating -- you can think of it as a kind of wallpaper.
254
762000
3000
13:03
They're thinking about putting it on the insides of buildings
255
765000
4000
13:07
to move water up without pumps.
256
769000
6000
13:13
Amazon electric eel -- incredibly endangered,
257
775000
2000
13:15
some of these species --
258
777000
2000
13:17
create 600 volts of electricity
259
779000
4000
13:21
with the chemicals that are in your body.
260
783000
3000
13:24
Even more interesting to me is that
261
786000
2000
13:26
600 volts doesn't fry it.
262
788000
3000
13:29
You know we use PVC, and we sheath wires
263
791000
3000
13:32
with PVC for insulation.
264
794000
2000
13:34
These organisms, how are they insulating
265
796000
2000
13:36
against their own electric charge?
266
798000
3000
13:39
These are some questions that we've yet to ask.
267
801000
3000
13:42
Here's a wind turbine manufacturer that went to a whale.
268
804000
4000
13:46
Humpback whale has scalloped edges on its flippers.
269
808000
4000
13:50
And those scalloped edges
270
812000
2000
13:52
play with flow in such a way
271
814000
3000
13:55
that is reduces drag by 32 percent.
272
817000
3000
13:58
These wind turbines can rotate in incredibly slow windspeeds, as a result.
273
820000
6000
14:04
MIT just has a new radio chip
274
826000
3000
14:07
that uses far less power than our chips.
275
829000
4000
14:11
And it's based on the cochlear of your ear,
276
833000
3000
14:14
able to pick up internet, wireless, television signals
277
836000
5000
14:19
and radio signals, in the same chip.
278
841000
3000
14:22
Finally, on an ecosystem scale.
279
844000
4000
14:26
At Biomimicry Guild, which is my consulting company,
280
848000
3000
14:29
we work with HOK Architects.
281
851000
2000
14:31
We're looking at building whole cities
282
853000
4000
14:35
in their planning department.
283
857000
2000
14:37
And what we're saying is that,
284
859000
2000
14:39
shouldn't our cities do at least as well,
285
861000
3000
14:42
in terms of ecosystem services,
286
864000
2000
14:44
as the native systems that they replace?
287
866000
3000
14:47
So we're creating something called Ecological Performance Standards
288
869000
4000
14:51
that hold cities to this higher bar.
289
873000
4000
14:55
The question is -- biomimicry is an incredibly powerful
290
877000
3000
14:58
way to innovate.
291
880000
3000
15:01
The question I would ask is, "What's worth solving?"
292
883000
3000
15:04
If you haven't seen this, it's pretty amazing.
293
886000
2000
15:06
Dr. Adam Neiman.
294
888000
3000
15:09
This is a depiction of
295
891000
2000
15:11
all of the water on Earth
296
893000
2000
15:13
in relation to the volume of the Earth --
297
895000
2000
15:15
all the ice, all the fresh water, all the sea water --
298
897000
3000
15:18
and all the atmosphere that we can breathe, in relation to the volume of the Earth.
299
900000
4000
15:22
And inside those balls
300
904000
2000
15:24
life, over 3.8 billion years,
301
906000
4000
15:28
has made a lush, livable place for us.
302
910000
5000
15:33
And we are in a long, long line
303
915000
3000
15:36
of organisms
304
918000
2000
15:38
to come to this planet and ask ourselves,
305
920000
3000
15:41
"How can we live here gracefully over the long haul?"
306
923000
4000
15:45
How can we do what life has learned to do?
307
927000
5000
15:50
Which is to create conditions conducive to life.
308
932000
4000
15:54
Now in order to do this, the design challenge
309
936000
4000
15:58
of our century, I think,
310
940000
3000
16:01
we need a way to remind ourselves of those geniuses,
311
943000
5000
16:06
and to somehow meet them again.
312
948000
3000
16:09
One of the big ideas, one of the big projects
313
951000
2000
16:11
I've been honored to work on
314
953000
2000
16:13
is a new website. And I would encourage you all to please go to it.
315
955000
3000
16:16
It's called AskNature.org.
316
958000
3000
16:19
And what we're trying to do, in a TEDesque way,
317
961000
3000
16:22
is to organize all biological information
318
964000
2000
16:24
by design and engineering function.
319
966000
4000
16:28
And we're working with EOL, Encyclopedia of Life,
320
970000
3000
16:31
Ed Wilson's TED wish.
321
973000
2000
16:33
And he's gathering all biological information
322
975000
3000
16:36
on one website.
323
978000
2000
16:38
And the scientists who are contributing to EOL are answering a question,
324
980000
3000
16:41
"What can we learn from this organism?"
325
983000
3000
16:44
And that information will go into AskNature.org.
326
986000
4000
16:48
And hopefully, any inventor, anywhere in the world,
327
990000
3000
16:51
will be able, in the moment of creation,
328
993000
3000
16:54
to type in, "How does nature remove salt from water?"
329
996000
5000
16:59
And up will come mangroves, and sea turtles
330
1001000
3000
17:02
and your own kidneys.
331
1004000
2000
17:04
And we'll begin to
332
1006000
3000
17:07
be able to
333
1009000
2000
17:09
do as Cody does,
334
1011000
2000
17:11
and actually be in touch
335
1013000
3000
17:14
with these incredible models,
336
1016000
3000
17:17
these elders that have been here
337
1019000
2000
17:19
far, far longer than we have.
338
1021000
2000
17:21
And hopefully, with their help,
339
1023000
2000
17:23
we'll learn how to live on this Earth,
340
1025000
3000
17:26
and on this home that is ours, but not ours alone.
341
1028000
4000
17:30
Thank you very much.
342
1032000
2000

ABOUT THE SPEAKER
Janine Benyus - Science writer, innovation consultant, conservationistA self-proclaimed nature nerd, Janine Benyus' concept of biomimicry has galvanized scientists, architects, designers and engineers into exploring new ways in which nature's successes can inspire humanity.
Why you should listen
In the world envisioned by science author Janine Benyus, a locust's ability to avoid collision within a roiling cloud of its brethren informs the design of a crash-resistant car; a self-cleaning leaf inspires a new kind of paint, one that dries in a pattern that enables simple rainwater to wash away dirt; and organisms capable of living without water open the way for vaccines that maintain potency even without refrigeration -- a hurdle that can prevent life-saving drugs from reaching disease-torn communities. Most important, these cool tools from nature pull off their tricks while still managing to preserve the environment that sustains them, a life-or-death lesson that humankind is in need of learning.
As a champion of biomimicry, Benyus has become one of the most important voices in a new wave of designers and engineers inspired by nature. Her most recent project, AskNature, explores what happens if we think of nature by function and looks at what organisms can teach us about design.
