Art that hides in plain sight

We’re presented with many wonders — objects rendered weightless, or put into permanent vibration, vaporous blue mercury and traffic signals turned into lonely, monstrous eyes. And as the show progresses (it’s surprisingly large, designed to unfold around corners and spring surprises at your back) the work gets less intuitive, and a lot louder. A pendulum, orbiting a strong, floor-mounted magnet, whips eccentrically and not at all gently about its centre of attraction. It’s like nothing in visible nature. There’s no “magnetic breeze” here, no “force like gravity”, just the thing, the weirdness itself. Now we’re getting somewhere.

A clown, a fool, a “klimatosser”

I went round to Olafur’s house for New Scientist, 13 July 2019

SIXTEEN years ago, Danish-Icelandic artist Olafur Eliasson caught London off guard with a massive indoor artwork. Some 2 million people visited The Weather Project at the Tate Modern gallery to bask in the glow of a giant, artificial sun. It was a rare moment of collective awe – created using the simplest of materials. This week, Eliasson is back with a major retrospective exhibition and most of the pieces are new to the UK. But a lot has changed since 2003. Days before his new show opens, we asked the artist about selfie culture, what accessible art looks like in the teched-up Anthropocene, and the hefty carbon footprint that pictures and installations leave behind.

Do big art and big science have to justify themselves to people who don’t get the point?

Sadly, yes, and it’s an argument we’re losing because great science and great art are very much long-term projects, views given to politicians with short-term goals. Making a work might take 10 years. Getting it shown might take another 10. For people to finally settle down with the experience might take 10 years, too. It’s a very slow piece of communication.

You command big budgets. Is the relationship with money tricky for artists?

To make big projects is expensive. But think about how much money an alcohol company throws into the promotion of some new drink! I believe there are studies showing that if you throw a euro or a pound into the culture sector, it generates two to three times as much income. There are more people working in the culture sector than there are in the car industry. It’s also a part of our democratic stability. It’s a space where we feel we can have difficult conversations. Is that expensive? No. It’s actually very cheap.

What can we expect from the show at Tate Modern?

We have about 42 works, big and small. Some are entertaining, like Your Uncertain Shadow and Your Blind Passenger, where a tunnel full of smoke gives you the experience of being blind. Of course, instantly your ears get more active, you touch the wall and stretch out your hand so as not to bump into somebody. Other works are more contemplative.

Wasn’t there a plan to stage something outside the gallery?

Yes. We’re installing three waterfalls. We know today there are no real waterfalls left because they’re all human-influenced, if not human-made. So our waterfalls are as real as anything in nature – or as unreal.

Do you consider yourself an environmental artist?

In the show, there is a series of 40 photos of glacial tongues from Iceland, taken in 1998. I believed then that culture and nature were two distinct spaces. I didn’t fully understand that the Anthropocene age had started. When people look at the photos now, they say “this is about climate”. When I took them, it was about their beauty. Soon, I’ll be retaking those photos from the same angles, in the same places. Maybe in October, if I’ve finished, we will sneak in the new pictures so we have the two series hanging next to each other, 20 years apart.

In December, you brought 30 polar ice blocks from Greenland to London and let them melt. Why?

Some 235,000 people were estimated to have been not just walking by, but at the ice – sometimes physically hugging it – and this, I think, made Ice Watch a clear and robust statement. This is what the data from the scientists looks like. This is what a block of ice 15,000 years old looks like. And it’s going to be gone in a week.

How big is the carbon footprint of your work?

We worked with a consultancy called Julie’s Bicycle, which helps people in the culture sector calculate their climate footprint. The London project came to the equivalent of 52 return flights from London to Ilulissat in Greenland. For almost two years, we’ve been trying to come up with a step-by-step solution for my Berlin studio. And whenever I work with museums and logistics teams, I ask them to come up with a response to the climate.

Our readers care about green footprints, but does everyone?

I was with teenage children in Ethiopia in January. They knew all about global warming, they understood about greenhouse gases and how it wasn’t really them, their parents or their ecology that created this problem. There is no place left where people don’t know this. There are deniers in places like the White House who deny things because they’re following other economic or power priorities.

What can artists bring to the climate debate?

Recently, a far right Danish politician lost a huge number of voters and one of the most prominent members of that party said, well, it’s all these climate fools. And immediately, across the political spectrum, people picked up on it, saying “I’m a clown, a fool, a klimatosser“. If we’re going to re-engineer the systems of tomorrow, we need to risk being foolish. Previous models of success can’t be applied. The planet simply can’t host them any longer. We need to take risks.

How has social media affected your work?

It’s kind of the stone age, the way people walk through exhibitions. People walk up to a piece of art that’s very tangible, highly emotional, with sounds and smells and all sorts of things – and they just bloody look at their phone! The problem isn’t necessarily the audience, but the way institutions over-explain everything, as though without a long text people just won’t get it. And once we are used to that, that’s how we react: “My God, there was no text! I had to find out everything myself!” I say, yes, art and culture are hard work, not consumerism. You have to give something to get something.

Does activism consume much of your working life?

I’m lucky that art can be seen to be flirting with activism, and maybe there is a fertilising relationship there. But that’s one of the good things about getting older: you know there are things that you aren’t good at. I’m very content just being an artist.

But you run a business to drive social change.

I have a social entrepreneurship project called Little Sun, which makes a small, handheld, portable solar lantern. On one side, it has a photovoltaic panel, on the other an LED. It replaces the kerosene or petroleum lantern that you would have used previously. Obviously, sitting with an open-wick petroleum lantern is both very unhealthy and very bad for the climate. It’s also expensive.

Is the Little Sun a success?

We’ve done studies on the impact of the lamp. Say a family eats dinner, then the girl does the dishes while the boy does his homework. Once the girl is done, she sits down only to find there’s not enough petroleum left for her homework. One study showed that the Little Sun increased the boy’s homework efficiency by 20 per cent, but increased the girl’s efficiency by 80 per cent. So the Little Sun project is incredibly inspiring.

 

Venice in interesting times

Visiting May You Live In Interesting Times, the 58th International Art Exhibition at the Venice Biennale, for New Scientist, 16 May 2019

BETWEEN now and 24 November, half a million people will visit May You Live in Interesting Times, the main art exhibition of the Venice Biennale. More than 120 years old, the Biennale is the world’s biggest and most venerable art fair. This year’s offering overflows its historical venue in the gardens on Venice’s eastern edge and sprawls across the city.

In a 300-metre-long former rope-making factory in Venice’s Arsenale, a complex of former shipyards and armouries, it is hard to miss data-verse 1 by Japanese DJ and data artist Ryoji Ikeda: the first instalment of a year-long project to realise an entire universe on a gigantic, wall-sized high-definition screen.

Back in Paris, in a studio that consists of hardly more than a few tables and laptops, Ikeda and his programmers have been peeling open huge data sets, using software they have written themselves. From the flood of numbers issuing from CERN, NASA, the Human Genome Project and other open sources, they have fashioned highly detailed abstract animations.

Ikeda is self-taught. He came to visual art from making animations to accompany DJ sets in the squats, clubs and underground parties of Kyoto, Japan. While his own musical taste was eclectic in the extreme, “from classical to voodoo”, Ikeda was drawn to house and dub: forms in which he says “the sound system is the real subject, not the music being played”.

His own “music” reduces sound to sine waves and impulses – and the animations to accompany his sets are equally minimal. “If the sine wave is the simplest expression of sound, what’s the simplest expression of light? For the scientist, that’s a complicated question, but for the artist, the answer is simple: it’s the pixel,” he says.

Ikeda’s project to reduce the world to its essentials continues: “I wondered what would happen if matter were reduced the same way.” Now Ikeda has turned himself into one of art’s curious beasts, the pure “data artist”.

Each of data-verse 1‘s 15-minute-long abstract “dances” explores the universe at a different scale, from the way proteins fold to the pattern of ripples in the cosmic background radiation. However, Ikeda’s aim is not to illustrate or visualise the universe, but to convey the sheer quantity of data we are now gathering in our effort to understand the world.

In the Arsenale, there are glimpses of this new nature. The Milky Way, reduced to wheeling labels. The human body, taken apart and presented as a sequence of what look like archaeological finds. A brain, colour-coded, turned over and over, as if for the inspection of a hyperactive child. A furious blizzard of solar images. And other less-easily identified sequences, where the information has peeled away entirely from the thing it represents, and takes on a life of its own: red pixels move upstream through flowing numbers like so many salmon.

Ikeda differs from his fellow data artists. While a generation has embraced and made art from “big data” – the kind of dynamic information flow that derives from recording a constantly changing world – Ikeda remains wedded to an earlier, more philosophical definition of data as the record of observed facts. Chaos and complexity for their own sake do not interest him. “I never use dynamic data in my work,” he says.

He did try, once. In 2014, he won a residency at the Large Hadron Collider at CERN, Switzerland. But he found the data overwhelming. “They have supercomputers and one experiment takes two years to analyse and compute,” he says, “and still it’s not really enough. They proposed I use this dynamic data, but how could one single artist handle this? We talk of ‘big data’ but no one imagines really how big it is.”

So Ikeda’s data-verse 1 project, which will take a year and two more productions to reach fruition, is founded on that most old-fashioned of ideas, a record of objective truth. It is neither easy nor cheap to realise, and is being supported by watch-makers Audemars Piguet, an increasingly powerful patron of artists who operate on the boundaries between art and science.

Last year, the firm helped Brighton-based art duo Semiconductor realise their CERN-inspired kinetic sculpture HALO. Before that, it invited lidar artist Quayola to map the Swiss valley where it has its factory.

While Audemars Piguet has an interest in art that pushes technological boundaries, Ikeda fights shy of talk of technology, or even physics. He is interested in the truth bound up in numbers themselves. In an interview with Japanese art critic Akira Asada in 2009, he remarked: “I cannot help but wonder if there are any artists today that give real consideration to beauty. To me, it is mathematicians, not artists, who epitomise that kind of individual. There is such a freeness to their thinking that it is almost embarrassing to me.”

Other highlights at the Arsenale include Dominique Gonzalez-Foerster’s Endodrome, (above) a purely virtual work, accessed through a HTC Vive Pro headset. The artist envisioned it “as a kind of organic and mental space, a slightly altered state of consciousness”. Manifesting at first as a sort of hyper-intuitive painting app, in which you use your own outpoured breath as a brush, Endodrome’s imagery becomes ever more precise and surreal. In a show that bristles with anxiety, Gonzalez-Foerster offers the festival-goer an oasis of creative contemplation.

Also at the Arsenale, and fresh from her show Power Plants at London’s Serpentine Gallery, the German artist Hito Steyerl presents This Is the Future, (above) a lush, AI-generated garden of the future, all the more tantalising for the fact that you’ll probably die there. Indeed, this being the future, you’re sure to die there. Steyerl mixes up time and risk, hope and fear, in a wonderfully sly send-up of professional future-gazing.

The Giardini, along the city’s eastern edge, are the traditional site of La Biennale Art Exhibitions since they began in 1895. They’re where you’ll find the national pavilions. Hungary possesses one of the 29 permanent structures here, and this year it’s full of imaginary cameras. They’re the work of cartoonist-turned media artist Tamás Waliczky. Some of his Imaginary Cameras and Other Optical Devices (above) are based on real cameras, others on long-forgotten 19th-century machines; still others are entirely fictional (not to mention impossible). Can you tell the difference? In any event, this understated show does a fine job of reminding us that we see the world in many, highly selective ways.

There’s quite as much activity outside the official venues of the Biennale as within them. At the Ca’ Rezzonico palazzo until 6 July, you have a chance to save an internationally celebrated artist from drowning (or not- it’s really up to you). A meticulously rendered volumetric avatar of Marina Abramović beckons from within a glass tank that is slowly filling with water, in a bid to draw attention to rising sea levels in a city which is famously sinking. Don’t knock Rising (above) till you’ve tried it: this ludicrous-sounding jape proved oddly moving.

Back at the Arsenale, Ed Atkins reprises his installation Olde Food, (above) which had its UK outing at London’s Cabinet gallery last year. Atkins has spent much of his career exploring what roboticist Masahiro Mori’s famously dubbed the “uncanny valley” — the gap that is supposed to separate real people from their human-like creations. Mori’s assumption was that the closer our inventions came to resembling us, the creepier they would become.

Using commercially purchased avatars which he animates using facial recognition software, Atkins has created his share of creepy art zombies. In Olde Food, though, he introduces a new element: an almost unbearably intense compassion.

Atkins has created a world populated by uncanny digital avatars who (when they’re not falling from the sky into sandwiches — you’ll have to trust me when I say this does make a sort of sense) quite clearly yearn for the impress of genuine humanity. These near-people pray. They play piano (or try to). They weep. They’re ugly. They’re uncoordinated. They’re quite hopeless, really. I do wish I could have done something for them.

“Bloody useless at objects. Bloody brilliant at space”

Playing Lunatick by Antony Gormley and Priyamvada Natarajan for New Scientist, 27 March 2019

VISIT The Store X, a venue for art and design in London’s West End, and you are in for quite a journey. Wearing an HTC Vive headset, you are given an island to explore in Lunatick, a glossy, game-like virtual-reality experience that starts at Kiribati in Micronesia. For a while, you have the run of the place by means of hand controllers, although producers Acute Art plans to use EEG to let you control it with your thoughts.

Don’t get too comfortable. Wandering past a stone platform triggers the space elevator. It lifts you gently off your feet, then propels you through the stratosphere. This long, beautiful and increasingly uncanny transit carries you into the void between the moon and Earth.

Take a breath. Look around you. The geometrical relationship between the sun, Earth and its moon unwinds around you as time skews and the moon swells. Before you know it, you are skating around lunar crater rims, plummeting into craters, flying high, until, losing control again, you are flung into the sun.

Lunatick is the first joint work by British artist Antony Gormley and astrophysicist Priyamvada Natarajan from Yale University. Natarajan visualises the accretion history of black holes, and maps the granularity of dark matter by studying the way it bends light – a phenomenon called gravitational lensing. But she couldn’t resist the idea of giving space a sensual dimension by making the vastness and loneliness of the cosmos tangible.

Artist and scientist bonded over their early love of science fiction. H. G. Wells’s 1901 novel The First Men in the Moonwas Natarajan’s contribution: a fictional journey powered by the mysterious gravity-less mineral cavorite. Gormley, in his turn, recalled C. S. Lewis’s space trilogy that began with Out of the Silent Planet, in which a man travels the solar system pinned in a coffin.

Both influences emerge clearly enough in Lunatick, but the real star of the show isn’t fictional: it is the flyable lunar terrain wrestled into shape by Rodrigo Marques, Acute Art’s chief technology officer, from data sent back by NASA’s Lunar Reconnaissance Orbiter. “There’s something both moving and funny about skating over the surface of the moon,” says Gormley. “I’ve got very fond of skiing along the ridges then down into the crater bottoms.”

Gormley’s art is popular globally, not least because people find it easy to grasp. Never mind the cosmological and philosophical dimensions: what strikes the viewer is how he renders, in solid matter, the building blocks of our lives.

Gormley has been making sculptural art out of wireframes and voxels (three-dimensional pixels), even as architects and games designers having been moving away from model-making into a purely virtual 3D design space. “Until recently, I had no idea what a voxel was,” says Gormley, who has spent more than five years making oddly expressive low-resolution sculptures assembled from cubes and cuboids. His wireframe experiments (assembled from real wires and rods) are older still, dating back to the late 1990s.

Why has Gormley chosen to enter the virtual realm now? First, Lunatick was a chance to explore a medium that, he says, is “bloody useless at objects and bloody brilliant at space”. Objects, ultimately, are bodies: VR is hobbled because it can’t convey their mass and tactility. But space is different. We perceive space primarily through seeing, which means VR can convey scale and immensity to a sublime degree.

But why should an artist best known for exploring the sculptural possibilities of the human body (particularly his own) be keen on disembodied space? The image of body-as-spaceship crops up intermittently in Gormley’s work, but rarely so urgently. He says he is haunted by an image of long-haul flight, where the shutters are down and everyone is watching movies: virtual versions of human life.

“I want this piece to say to people, ‘Break out!’,” he says. “Of course we get very obsessed with human matters. But there are bigger affairs out there. Recognise your cosmic identity!”

Slightly fleshy, slightly scabby, cast adrift

Exploring Matthew Day Jackson’s show Pathetic Fallacy at Hauser & Wirth Somerset for the Times Literary Supplement, 26 February 2019

The New York-based artist Matthew Day Jackson takes mixed media seriously. Behind the techniques and materials, the molten lead and the axe handles, the T-shirts and laser-etched Formica, Jackson’s aesthetic sees the world not as a continuum but as a mass of odd juxtapositions. Since his first big solo show in 2004, he has intertwined the grotesque and the beautiful. Every ten years, he paints a picture of himself as a corpse, but the majority of his work is mischievous, holding the autobiographical and the cerebral in an uneasy balance.

Hauser and Wirth, an international gallery with a strong educational remit, regularly brings its spikier artists to its property in Bruton, Somerset, to stay, work and reflect. The residencies come without strings, there are no prescribed outcomes, and one suspects there’s a certain mischief in who gets chosen. First to arrive, in 2014, was the (intermittently scary) video artist Pipilotti Rist. Seduced by her surroundings, she came up with sensuously observed close-ups of bodies and leaves in intimate proximity. Nothing wrong with that, of course. But it’s a risk for the gallery, and a challenge for the artists who stay here, that the landscape round about is so ridiculously seductive.

Showing next door to Matthew Day Jackson, Eve, an exhibition of paintings by the Somerset-based artist Catherine Goodman, is unashamedly paradisal. Even its edge of Freudian melancholy proves heartwarming in the end.

What on earth will Jackson, a cerebral city-dwelling proponent of an aesthetic he dubs the “horriful”, do with all this serried loveliness? He says that at first he found the landscape hard to read. “It’s more like urban space”, he says. “Everywhere you look, you can trace how humans have engaged with this place.” He can’t get over the time-worn depth of the lanes here. There’s no equivalent back home: “Maybe in Oregon and Wyoming, you can find tracks still rutted by wagon wheels”.

Predictably, for an artist who’s spent his career mapping the failures of American utopianism, Jackson has responded to the beauty around him by mourning its passing. His Solipsist collage-paintings of silk-screened Formica zoom out to encompass large swathes of the planet. Seen from various orbital viewpoints (the images are based on photographs taken by NASA astronauts) four elements emerge. Mine workings strip the Earth back to, well, its earth. The hopelessly polluted Ganges and the virtually vanished Ural Sea stand for water. Smoke plumes from forest fires give a shape to air. Yellowstone Lake inhabits a caldera that, if it erupted, would consume most life on Earth.

Each landscape, weirdly colourized (“Formica limits your colour palette”), laser etched with precise contours and subtle, uninterpretable boundary lines, resembles a computer-readable map. “Over” it (or, to be literal about this, embedded in it) is the flattened image of a satellite, made of cast lead.

The fact that the satellite observing the view is itself melted into the picture suggests a colossal foreshortening. There’s something suggestive of Jean Dubuffet, too, in the way the texture of the satellite is employed to convey a radical flatness. There’s no shade here, no occlusion, no hint of curvature. Human activity and human destiny are being measured and metricized to the point where even the planet has nowhere to turn.

Jackson’s flower paintings in the next room continue the theme: vases of hallucinatory Formica and fabric blooms, backlit by unearthly aurorae that may reference the tie-dye fad of the early 1970s but are more likely – given the way this show is going – something ghastly to do with nuclear testing.

The paintings work with the Astroturf floor and Jackson’s experimental, sculptural furniture to explore the idea that we only ever see things through their use. This isn’t a human foible: living things generally only sense what is relevant to their survival. So if Jackson is holding humanity to account here, it is a gentle and considered judgement. “What we most want is to feel that we exist”, he says, as we contemplate vanished seas and shredded mountain ranges. “We want not be lonely. Hence the appeal of metrics: they give us a sense of accomplishment.”

It can be a nuisance, having the artist around when you’re viewing a show. I was initially thinking about our greed and rapacity, and now, looking at these spoiled and garishly mapped earths, all I can see is our pathos: how we are polishing our rock down to the granite, just so we can glimpse ourselves in it.

Pathetic Fallacy is a well-chosen title for this show. John Ruskin coined the phrase to have a dig at the emotional falsity of poets who made clouds weep and trees groan. Jackson’s show is more in the spirit of Wordsworth’s defence of the practice, arguing that “objects . . . derive their influence not from properties inherent in them . . . but from such as are bestowed upon them by the minds of those who are conversant with or affected by these objects”.

In other words, we impose ourselves on the world because we feel we are the only meaning makers. On the way out, I pass more pictures: flattened lead satellites, cast in moulds made of corrugated cardboard, twine, sawdust, glue. This close, they appear slightly fleshy, slightly scabby, cast adrift, and travelling out into space.

Tonight the World

We could be in for a rather stilted, tech-heavy exploration of the artist’s fraught family’s  history. But the way the gallery has been decked out suggests (rightly) that a warmer, more intimate, ultimately more disturbing game is afoot. Past the first screen, fellow gallery-goers bleed in and out of view round a series of curved wooden walls painted a warm terracotta. Is the colour a reference to interwar architecture? All I can think of is the porn set in David Cronenberg’s existentialist shocker Videodrome. There is something distinctly fleshy going on.

A place that exists only in moonlight

Image result for Katie Paterson and JMW Turner at Turner Contemporary — worlds apart

Paterson cares about measurement. Turner cared about witness. An honestly witnessed play of light against a cloud can be achieved through the right squiggle. An accurate measurement of the same phenomenon must be the collaborative work of meteorologists, atmospheric scientists, astronomers, colour scientists, and who knows how many other specialists, with Paterson riding everyone’s coat-tails as a sort of tourist.

Implausible science and ambiguous art

The point — that the physicists working at CERN’s Large Hadron Collider in Geneva might be constructing the very quantum reality they were hired to study — is lost on none of the 10,000-odd scientists and engineers involved with the project. And this awareness — that the very idea of science is up for grabs here — may explain why CERN’s scientists have taken so warmly to the artists dropped in their midst.

Edward Burtynsky: Fossil futures

An overview of The Anthropocene Project for New Scientist, 10 October 2018

THE lasting geological impact of our species is clearly visible within the galleries of this potash mine in Russia’s Ural mountains. The Urals contain one of the largest deposits in the world of this salt, one of the most widely used fertilisers. Mining has left behind vast subterranean galleries, their walls machine-carved with enormous ammonite-like whorls.

The Canadian photographer and artist Edward Burtynsky took this photograph for The Anthropocene Project, a collaborative chronicle of geologically significant human activity such as extraction, urbanisation and deforestation. Works from the project are on display at the Art Gallery of Ontario and the National Gallery of Canada, while this image and other photographs feature in Burtynsky’s exhibition The Human Signature, at London’s Flowers Gallery, to 24 November.

This September also saw the release of a documentary film, Anthropocene: The human epoch, and a book of colour photographs by Burtynsky, which includes new writing from author and poet Margaret Atwood.

Through publications, films and immersive media, Burtynksy and his Anthropocene Project collaborators – filmmakers Jennifer Baichwal and Nicholas de Pencier – convey the unsettling visual reality of resource depletion and extinction: how our planet’s surface is being scarred, ground and shovelled into abstract, almost painterly forms.

The effects of mining, in particular, are irreversible. While animal burrows reach a few metres at most, humans carve out networks that can descend several kilometres, below the reach of erosion. They are likely to survive, at least in trace form, for millions or even billions of years.

There is an eerie poetry to this: burrows found in 500-million-year-old sediment tipped off geologists to the massive diversification of animal forms known as the Cambrian explosion. Will our own gargantuan earthworks commemorate more than just a mass extinction event?

Tomás Saraceno: Beneath an ocean of air

Visiting Tomás Saraceno’s Berlin studio for New Scientist, 13 October 2018

THE Argentine-born artist Tomás Saraceno maintains a studio in Berlin – if you can call a disused chemicals factory a studio. There is nothing small about this operation. Saraceno, who trained as an architect in Buenos Aires, now employs hundreds of people, with specialisms ranging from art history and architecture to biology and anthropology. If you’re serious about saving the world, you need this kind of cross-disciplinary team, I suppose.

Though Saraceno hasn’t exactly promised to save the world, he has been dropping some big hints. His utopian installations include Cloud Cities at Hamburger Bahnhof, Berlin, in 2011 – a collection of geometric, inflated shapes. Even by the time of his Observatory/Air-Port-City show at London’s Hayward Gallery in 2008, these shapes contained autonomous residential units. A network of habitable cells floated in the air, combining and recombining like clouds.

A year later at the Metropolitan Museum in New York, gallery-goers got to explore these spaces via 16 interconnected modules made up of glass segments held in place by steel cables. And in June 2013, the K21 gallery in Düsseldorf invited visitors to wander more than 25 metres above the gallery’s piazza across a web dotted with inflated PVC spheres.

This is Saraceno’s answer to our global problems: he wants us to take to the air. That’s why he coined the term “Aerocene” for one of his projects. He wants people to think of climate change in terms of possibility, playfulness and, yes, escape. “We live beneath an ocean of air,” he once wrote, as he sketched his utopian vision of a city in the clouds. “But we’ve yet to find a way to inhabit it.”

Near his Berlin studio is a scruffy public park. Part of it is marked out for football. Behind one goal stands a graffitied stretch of the Berlin Wall. Today there’s another attraction: two men are running back and forth, trying to fill a black bag as big as a minivan with air. It is a fine, windless day; the air in the bag heats up quickly, and once it is sealed, the container rises into the sky. A bag no longer, it is clearly recognisable as one of Saraceno’s signature tetrahedral solar balloons.

These black balloons have been plying the skies since 2007. They are mascots of the artist’s multi-stranded effort to combine engineering, architecture and the natural sciences to create a new, democratic kind of environmental art, made of bubbles and aerial platforms and webs. An art that mitigates climate change, he says, and makes the sky habitable, by establishing a modular, transnational settlement in the skies through solar balloons that require no fuel at all. An art that ushers in utopia.

Could it be that this chap is just playing about with balloons? Trying to calculate Saraceno’s level of seriousness is half the fun. Over lunch, for instance, he tells me that he wants to return us “to a sort of Mayan sensitivity towards celestial mechanics”.

But some of his efforts are admirably practical. The balloon I’d just seen being demonstrated was an Aerocene Explorer: it comes in a backpack complete with instructions on how to create and fly lightweight sensors. Any data collected can be uploaded and shared with Aerocene’s online community, via a website where participants from all over the world are sharing their experiments and innovations.

Practicalities aside, much of Saraceno’s work is simply beautiful. For a show opening at the Palais de Tokyo in Paris on 17 October, the team is busy building playful orreries, mechanical models of the solar system that combine planetary orbits with the physics of soap bubbles and webs spun by his pet Cyrtophora citricola spiders.

These unbelievably delicate confections will be on show with some mirrored umbrellas that also double as solar cookers. When arranged in concentric circles, Saraceno imagines that in the manner of a solar thermal power plant, the umbrellas might even concentrate enough heat to inflate a large balloon. He hopes to try out the idea when Audemars Piguet – a Swiss watch manufacturer that has recent form in backing innovative science-inflected art – takes parts of his sprawling Aerocene endeavour to Miami this December for the Art Basel fair.

Meanwhile, there are myriad things to organise for Paris: workshops, concerts, public symposiums uniting scientific institutions, researchers, activists, local communities, musicians and philosophers. As he says: “People aren’t very interested in simple ideas. You have to give things a little bit of complication to get the audience to engage.”

balloons

He found this out the moment he started using solar balloons. The balloons, which work by simply zipping up some air in a heat-absorbing bag, have been around since the 1970s. His own projects have demonstrated their usefulness in meteorology, pollution monitoring, even passenger transport. In 2015, he flew in a tethered solar balloon over the dunes of White Sands in New Mexico, where the US launched its first rockets and where the world’s first tourist spaceport is located. The Massachusetts Institute of Technology got in on the act, and created technology so that you can use the Aerocene.org website to plan a meteorologically feasible journey, by balloon, from Point A to Point B, anywhere on Earth.

“Rats saved at the point of giving up fought for life 240 times longer when returned to danger”

Here’s the paradox. Saraceno’s work has always been playful, and part of the game, he explains, has been “trying to sell this work as some sort of global solution to something”. But while his visions of an airborne utopia remain as remote as ever, his Aerocene project has spawned a foundation that uses lightweight balloons for climate activism and pollution monitoring. And even the absurd spectacle of someone jetting from country to country to fly fuel-less balloons has become part of the art, as Saraceno’s studio begins to record his own carbon footprint.

Saraceno makes an important point about how we address climate change in our lives. The trick, he says, is not to let the perfect get in the way of the good. Escapism is fine. He has no time for the way so many artists and pundits are ringing humanity’s death knell. He has a special contempt for the lazy way the word Anthropocene crops up now in every climate conversation, as if, with the advent of this putative new era, our doom was sealed. “What a great way for a small number of people to disempower and demotivate us,” he says.

Given the seriousness of our environmental bind, isn’t escapism a bit irresponsible? Saraceno points me to a 1957 paper by psychobiologist Curt Richter. His gruesome experiments left rats to drown in water-filled containers from which they could not escape. But if he briefly rescued rats at the point they gave up swimming, and then returned them to the water, those rats continued to fight for life 240 times longer. Richter concluded that they had learned that there was hope. Faced with challenges on a planetary scale, we are scrambling for our lives, and can see no way out. “We need the energy those rats got when they saw some small hope,” says Saraceno.

I hadn’t expected our conversation to take this dark turn, but creating such small glimmers of hope is his business. If he is a joker, then he is one in the best sense of the word.

Should we take Saraceno’s work seriously? I was doubtful, but now I think, why look a gift horse in the mouth? He enthuses people. He gets us thinking. And he is right: a little hope goes a long way.
