ABOUT THE SPEAKER
Tomás Saraceno - Artist
Tomás Saraceno invites us to consider the impossible, like spiders that play music or cities in the sky.

Why you should listen

Tomás Saraceno’s oeuvre could be seen as an ongoing research informed by the worlds of art, architecture, natural sciences, astrophysics and engineering. His floating sculptures, community projects and interactive installations propose and explore new, sustainable ways of inhabiting and sensing the environment.

Aerocene, an open-source community project for artistic and scientific exploration initiated from Saraceno's vision, becomes buoyant only by the heat of the sun and infrared radiation from the surface of earth. In 2015, Saraceno achieved the world record for the first and longest certified fully-solar manned flight. During the past decade, he has initiated collaborations with renowned scientific institutions including the Massachusetts Institute of Technology, Max Planck Institute, the Nanyang Technological University of Singapore, and institutions of the Exhibition Road Cultural Group, among them Imperial College and the Natural History Museum London.

Saraceno lectures in institutions worldwide and directed the Institute of Architecture-related Art (IAK) at Braunschweig University of Technology, Germany (2014–2016). He was the first person to scan, reconstruct and re-imagine spiders' weaved spatial habitats, and he possesses the only three-dimensional spider web collection to existence. He has held residencies at Centre National d’Études Spatiales (2014–2015), MIT Center for Art, Science & Technology (2012–ongoing) and Atelier Calder (2010), among others. In 2009, Saraceno attended the International Space Studies Program at NASA Ames. The same year he presented a major installation at the 53rd Venice Biennale, and was later awarded the prestigious Calder Prize. Saraceno's work is included in the collections of The Museum of Modern Art, New York; SFMOMA, San Francisco; Walker Art Center, Minneapolis; Nationalgalerie, Staatliche Museen zu Berlin, Berlin; among others.

In a mind-bending talk that blurs the line between science and art, Tomás Saraceno exhibits a series of air-inspired sculptures and installations designed to usher in a new era of sustainability, the "Aerocene." From giant, cloud-like playgrounds suspended 22 meters in the air to a balloon sculpture that travels the world without burning a single drop of fossil fuel, Saraceno's work invites us to explore the bounds of our fragile human and terrestrial ecosystems.

This is my favorite place on earth,
0
1000
2674
00:15
Salar de Uyuni in Bolivia.
1
3698
2000
00:19
And when it's covered
in a thin layer of water,
2
7792
2616
00:22
it reflects the clouds.
3
10432
1167
00:23
There are days when you feel
as if you're floating among the clouds.
4
11623
4424
00:28
But there are days
when the horizon disappears;
5
16552
2897
00:31
there's no longer a top or a bottom.
6
19473
2420
00:33
You feel immersed in something bigger.
7
21917
3021
00:38
It was there that one night
I woke up from a dream,
8
26477
3944
00:42
and I saw that the stars
were also reflected on the water.
9
30445
2884
00:46
And that wasn't a dream.
10
34043
1394
00:47
It was as if you could walk
among the stars.
11
35461
2813
00:50
With every step I took,
the stars reverberated under my feet.
12
38298
3347
00:53
It was like I was floating in the universe
among clouds of galaxies.
13
41669
4928
00:59
But what's floating there today
are not just clouds of galaxies
14
47779
3204
01:03
but also clouds of plastic.
15
51007
2182
01:05
These are the footprints
we're leaving on the planet.
16
53213
2927
01:08
They're signs of an era
17
56830
2176
01:11
in which the behavior of some humans
is making a global impact
18
59030
3954
01:15
on our ecosystems.
19
63008
2463
01:18
This era is called the Anthropocene.
20
66257
2613
01:21
There's also another type
of toxic clouds that float in the air,
21
69322
3682
01:25
like the ones that form
from carbon dioxide emissions
22
73028
2936
01:27
and from the burning of fossil fuels --
oil, carbon, gas --
23
75988
3439
01:31
clouds that, when we see them,
24
79451
2190
01:33
pollute our dreams.
25
81665
1566
01:36
I don't know about all of you,
26
84055
1819
01:37
but I've always dreamed of floating
among the clouds.
27
85898
2612
01:40
Maybe today we can imagine together
other types of clouds,
28
88534
3573
01:44
clouds we can live with.
29
92131
1783
01:46
If you're wondering
about that photo, I'll explain:
30
94550
2621
01:49
it looks like a collage
or photomontage -- something weird.
31
97195
2943
01:52
No; it's reality.
32
100162
1356
01:53
But sometimes I ask myself:
What is reality?
33
101542
2526
01:56
According to Alexander Kluge:
34
104092
1669
01:57
"Human beings are not
interested in reality.
35
105785
2564
02:00
They can’t be; it’s part
of the human essence.
36
108373
3258
02:03
They have desires.
37
111655
1481
02:05
These desires are totally opposed
to any form of reality.
38
113977
3404
02:09
They prefer to lie
39
117405
1692
02:11
than to become divorced
from their desires."
40
119121
2193
02:14
But how can we learn
to float among the clouds?
41
122519
2873
02:18
As an artist, I thought we could start
building a flying museum.
42
126997
4897
02:24
You're probably wondering:
With plastic bags?
43
132458
2144
02:26
In 2007, with a community of people
all over the world,
44
134626
2940
02:29
we began to collect used plastic bags --
45
137590
2878
02:32
not new ones.
46
140492
1564
02:34
And we washed them,
47
142080
2000
02:36
we cut them up,
48
144865
1433
02:38
we glued them together,
49
146322
1427
02:39
and we began to draw on them,
50
147773
1944
02:41
creating a huge canvas.
51
149741
1823
02:43
We made a collection of drawings,
52
151588
2000
02:45
of personal stories
53
153612
1278
02:46
and of friendships.
54
154914
1604
02:48
And when you join them,
55
156542
1812
02:50
bend them and fold them,
56
158378
2000
02:52
it creates a space full of air.
57
160402
2371
02:54
When the sun comes up from the horizon,
58
162797
2194
02:58
the museum rises up to the sky.
59
166319
1854
03:00
That's why we call it,
"The Aero-Solar Museum."
60
168197
2311
03:02
And from this simple idea,
61
170532
1317
03:03
we learned how to float in the air
in a radically new way,
62
171873
2887
03:06
without using any type of fuel.
63
174784
2220
03:09
The difference in temperature
between the interior and the exterior
64
177028
3691
03:12
is what makes us rise up.
65
180743
2000
03:14
That way,
66
182767
1495
03:17
we don't use fossil fuels
or helium or hydrogen;
67
185316
4163
03:21
we don't use solar panels
68
189503
2166
03:23
or batteries or motors.
69
191693
2000
03:26
We discovered a way that's simple,
clean and accessible to the whole world
70
194248
5290
03:31
to lift ourselves up.
71
199562
1390
03:32
I remember when I was at NASA in 2009
with 120 engineers.
72
200976
4730
03:38
You guys know, too,
when you go up in a plane,
73
206383
2612
03:41
the control panels are gigantic.
74
209019
2063
03:43
And what we're doing is really complex,
75
211106
3616
03:46
and when I started coming in
with the plastic bags, saying,
76
214746
2972
03:49
"But we have a different way ..."
77
217742
1659
03:51
people had a hard time
understanding the concept.
78
219425
2340
03:53
Seeing the power of this idea,
79
221789
1544
03:55
we started to initiate a new era;
80
223357
1639
03:57
one that would leave behind
the violence of the Anthropocene
81
225020
2974
04:00
and give way to a new era,
82
228018
1487
04:01
which we call the "Aerocene" --
83
229529
2070
04:03
an era of ecological awareness,
84
231623
2816
04:06
in which we learn to float together,
live together in the air,
85
234463
3177
04:09
and come to an ethical commitment
86
237664
1665
04:11
with the atmosphere and with planet earth.
87
239353
2148
04:14
That's why I've brought
this backpack today.
88
242477
2121
04:16
Let's see ...
89
244622
1164
04:26
OK. This is a balloon
that we also refer to as a sculpture.
90
254996
3388
04:30
And if it's sunny out tomorrow,
we can go out and fly --
91
258408
2890
04:33
though, no, the weather
in Vancouver isn't --
92
261322
2312
04:35
(Laughter)
93
263658
1456
04:37
it's not very ...
94
265138
2068
04:39
very favorable.
95
267230
1185
04:41
So, what other features does it have?
96
269526
2073
04:43
It has sensors that, when it moves,
97
271623
2363
04:46
make sort of drawings in the air.
98
274010
2000
04:49
It also has other sensors.
99
277121
1572
04:50
I always think that first
you have to feel it,
100
278717
2200
04:52
and then you can measure it;
101
280941
1647
04:55
you need to hear the sounds
of the atmosphere,
102
283055
2270
04:57
of the climate, of the hot air,
103
285349
1534
04:58
in order to then measure the ozone,
104
286907
2071
05:01
the carbon dioxide.
105
289002
1793
05:02
We're developing these sensors
106
290819
1541
05:04
together with different communities
all over the world
107
292384
2677
05:07
in order to reconnect with the climate,
the temperature and the environment,
108
295085
3805
05:10
because there are other
species in the air;
109
298914
2214
05:13
in these excursions
towards the atmosphere,
110
301152
2048
05:15
we're not alone.
111
303224
1163
05:16
The air is full of clouds of life.
112
304411
1760
05:18
We live at the bottom of an ocean of air.
113
306195
2836
05:21
And this same sculpture,
114
309055
2213
05:24
this exact one in my hands,
115
312702
1358
05:26
flew 375 miles -- 12 hours --
from Germany to Poland,
116
314084
2777
05:28
on a fuel-free trip.
117
316885
1178
05:30
But it wasn't free from crossing borders.
118
318087
2153
05:32
The trip was much more complicated
than what we imagined;
119
320264
2866
05:35
air space is as regulated and militarized
120
323154
2118
05:37
as land space.
121
325638
1189
05:39
To fly using the winds,
the heat of the sun
122
327423
2449
05:41
and the radiant energy of the earth
123
329896
1738
05:43
is complex and beautiful.
124
331658
1611
05:45
But even more complex
will be getting the permits
125
333943
2374
05:48
to cross the air space
of each of the different countries
126
336341
3040
05:51
that we fly over using wind.
127
339405
1791
05:53
At COP21, the Paris Climate Conference,
128
341794
3803
05:57
we presented these spherical sculptures
129
345621
2122
05:59
that could transport us
all over the world.
130
347767
2526
06:02
But how can we fly using the wind
to arrive at our destination?
131
350317
3882
06:06
Together with MIT, we developed a program
132
354223
2449
06:08
that predicts how we can navigate
the wind highways.
133
356696
3080
06:11
For example, if I had to return
to Berlin from Vancouver,
134
359800
4021
06:15
the first thing I would need to do
is choose an altitude.
135
363845
2691
06:18
At different altitudes,
there are different directions
136
366560
2688
06:21
and different speeds.
137
369892
1243
06:24
The red line is tomorrow
and the orange, the day after tomorrow.
138
372035
3123
06:27
And there it goes.
139
375182
1168
06:28
You can see, the best day
to fly back to Berlin --
140
376374
3062
06:32
so now, traveling using only wind --
141
380594
2481
06:36
is in six days.
142
384114
1441
06:37
And we can get to 105 miles
from the center of Berlin
143
385579
3058
06:40
without burning a single drop of fuel,
144
388661
1909
06:42
being transported only by wind currents.
145
390594
2887
06:45
So we thought that these trajectories
that we drew with the wind
146
393505
3878
06:49
could become signatures, declaring
"Independence from Fossil Fuels Day."
147
397407
4633
06:54
More and more of us
are experiencing the air
148
402688
2690
06:57
in a different way.
149
405402
1206
06:59
You're all familiar with Earth Day.
150
407139
2121
07:01
We think we should also celebrate Air Day:
151
409284
2740
07:04
it's a pact that we make with the earth,
152
412048
1986
07:06
an ethical commitment to the atmosphere.
153
414058
2112
07:09
But let's keep thinking and dreaming.
154
417853
2052
07:11
We've learned that the bigger
the sculptures are,
155
419929
3165
07:16
the more weight they can lift.
156
424199
2658
07:18
Remember,
157
426881
1193
07:20
they rise up only with hot air
that's been heated by the sun.
158
428647
4549
07:26
Using this approach, we can learn
to build gardens in the air.
159
434148
3587
07:29
Could we one day live in a garden
the size of the earth?
160
437759
2959
07:33
Could we live in an ecosystem
floating among the clouds?
161
441448
3115
07:37
Answering these questions
isn't just a technological challenge;
162
445444
3627
07:41
it's a way to reexamine
the freedom of movement between countries,
163
449095
4193
07:46
and of overcoming the political,
social, cultural and military restrictions
164
454302
3787
07:50
of contemporary societies.
165
458113
1688
07:51
Because in the end,
166
459825
1673
07:53
the air belongs to everybody
167
461522
1697
07:55
and doesn't answer to any government.
168
463243
2333
07:58
(Applause)
169
466544
6304
08:05
And like we said earlier,
170
473388
1321
08:06
our imagination is the force
that allows us to create these places.
171
474733
4131
08:10
This is an installation I did
172
478888
1691
08:12
at the Metropolitan Museum
of Art in New York.
173
480603
2407
08:15
It asks the question:
174
483034
1277
08:16
What might these transnational
spaces be like?
175
484335
2744
08:19
And once we inhabit those spaces,
we need to learn how to move within them,
176
487103
4135
08:24
to walk among the clouds,
177
492039
2000
08:26
where every movement affects
everyone else's movements;
178
494571
3373
08:29
the body weight and proximity
between people
179
497968
3177
08:33
will cause the space to expand ...
180
501169
2024
08:35
or contract.
181
503217
1347
08:38
There we are, suspended
72 feet in the air.
182

When two or more people
get too close together,
183
509549
3214
08:44
even those farthest away are affected --
184
512787
3405
08:48
everyone falls to the same spot.
185
516216
2301
08:50
These are fragile ecosystems.
186
518541
2181
08:53
And it's between these spheres
that we build nets that connect us.
187
521943
4346
08:58
There are moments
when we have to face the void,
188
526313
3418
09:01
and fear can paralyze us.
189
529755
2000
09:04
One of the most beautiful things
about this exhibit
190
532459
2453
09:06
is the sense of solidarity generated
191
534936
1777
09:08
when we face these new "aero-graphs."
192
536737
2420
09:11
Finally,
193
539893
1556
09:13
let me tell you one last story.
194
541473
2000
09:15
On July 16, 1945,
195
543497
2174
09:17
on the White Sands of New Mexico,
196
545695
2000
09:19
an atomic bomb was detonated
for the first time.
197
547719
3216
09:23
As a result of this explosion,
198
551703
1608
09:25
a cloud of radioactive particles
disseminated all over the earth,
199
553335
4574
09:29
marking the beginning
of the Anthropocene era.
200
557933
2869
09:33
Seventy years later, on November 8, 2015,
201
561540
3197
09:36
in the same place,
202
564761
1554
09:38
another event occurred.
203
566339
1384
09:40
For the first time in history,
204
568561
1754
09:42
we lifted a person into the air
using only the sun,
205
570339
3158
09:45
without burning any fossil fuels.
206
573521
2773
09:48
As the sun rose up above the horizon,
207
576318
2502
09:50
we rose up, too,
208
578844
1637
09:52
silently,
209
580505
1664
09:54
slowly,
210
582193
1167
09:55
with no explosions.
211
583384
1506
09:56
We felt as if gravity had been inverted;
212
584914
2636
10:00
it wasn't pulling us
toward the center of the earth,
213
588125
2826
10:02
but toward the universe.
214
590975
1704
10:05
If Neil Armstrong said,
when he walked on the moon,
215
593381
2635
10:08
"That's one small step for man,
216
596040
1766
10:09
one giant leap for mankind,"
217
597830
2000
10:12
perhaps what we ought to ask ourselves is:
218
600631
2000
10:14
What steps do we need to take today?
219
602655
2700
10:17
In the Aerocene era,
220
605379
2432
10:19
our steps are much smaller,
but radically different;
221
607835
3670
10:24
they're steps that began with a bag
full of air and wishes,
222
612060
4192
10:29
but that can carry us
to independence from fossil fuels
223
617280
3930
10:33
and the opportunity to celebrate Air Day;
224
621234
2009
10:35
steps that won't leave footprints
on other planets
225
623267
3317
10:38
until we've learned to walk
in the atmosphere of this one.
226
626608
4251
10:42
The landscapes are tiny
227
630883
2055
10:44
and the steps are tiny,
228
632962
1570
10:46
but I hope we can take them together.
229
634556
2398
10:48
And I'm sure that these steps will lead us
much further than the moon,
230
636978
3824
10:52
so we can learn to float
with our feet on the ground.
231
640826
3900
10:56
Thank you.

ABOUT THE SPEAKER
Tomás Saraceno - Artist
Tomás Saraceno invites us to consider the impossible, like spiders that play music or cities in the sky.

Why you should listen

Tomás Saraceno’s oeuvre could be seen as an ongoing research informed by the worlds of art, architecture, natural sciences, astrophysics and engineering. His floating sculptures, community projects and interactive installations propose and explore new, sustainable ways of inhabiting and sensing the environment.

Aerocene, an open-source community project for artistic and scientific exploration initiated from Saraceno's vision, becomes buoyant only by the heat of the sun and infrared radiation from the surface of earth. In 2015, Saraceno achieved the world record for the first and longest certified fully-solar manned flight. During the past decade, he has initiated collaborations with renowned scientific institutions including the Massachusetts Institute of Technology, Max Planck Institute, the Nanyang Technological University of Singapore, and institutions of the Exhibition Road Cultural Group, among them Imperial College and the Natural History Museum London.

Saraceno lectures in institutions worldwide and directed the Institute of Architecture-related Art (IAK) at Braunschweig University of Technology, Germany (2014–2016). He was the first person to scan, reconstruct and re-imagine spiders' weaved spatial habitats, and he possesses the only three-dimensional spider web collection to existence. He has held residencies at Centre National d’Études Spatiales (2014–2015), MIT Center for Art, Science & Technology (2012–ongoing) and Atelier Calder (2010), among others. In 2009, Saraceno attended the International Space Studies Program at NASA Ames. The same year he presented a major installation at the 53rd Venice Biennale, and was later awarded the prestigious Calder Prize. Saraceno's work is included in the collections of The Museum of Modern Art, New York; SFMOMA, San Francisco; Walker Art Center, Minneapolis; Nationalgalerie, Staatliche Museen zu Berlin, Berlin; among others.
