After a week of very low temperatures, a rare opportunity has been made possible by especially harsh winter conditions in Berlin this year: a sharp radiant sun has uncovered above the city and its frozen waterways, allowing thousands of people to walk on thick ice. 

Early in the morning, a group of six Aerosolar Pilots borrowed three Backpacks from the Aerocene Foundation and experienced a flight free from carbon emissions on top of the frozen Rummelsburg lake in Berlin. 

The vast white surface of the lake had stopped any of its motions, no water ripples, boats remaining still in their positions, as decontextualized artefacts on a deserted land. Terrestrial beings are now bashfully walking where they were not allowed to only a day before. A spontaneous situationist environment has come to life, an empty, vast stage where the public and performers merge, activating a place for renewed shared experiences. 

As soon as the black Aerosolar sculptures get inflated on the ice with only air, the power of the sun lifts them off instantaneously – amplified by the albedo reflection effect on the white, frosty lake. Immediately, their movements in the thin air generate a focal point attracting the public and participants onto the wide white stage. 

The Aerosolar Pilots share their floating experience with whoever is around, passing the fluctuating rope and initiating a bonded, bonding slow dance between humans and the solar airborne creatures.

The transitory stage hosts the first act of a participatory piece in which the sun, the winds, human and non-human are all protagonists. 

Although the stunning beauty of the three hours experience, bathed in the wintry sun, it is not easy for the aeronauts to forget that under that thick layer of ice, down to the bottom of the lake, the contamination of several decades of industrial waste has made impossible life conditions for many autochthonous species. 

As stated by the Bundesanstalt für Gewässerkunde: 

“The combination of high chemical contamination with persistent organic and inorganic chemicals, toxicity and specific substrate composition, makes a natural repopulation scenario for the improvement of the biological diversity extremely improbable”

When leaving the lake, the aeronauts’ wish is that the mirage-like white blanket that has covered it for the day, allowing for them to fly aerosolar on top of it, will be a reminder of what lies beneath it, at its very bottom, where man-generated pollutant particles have layered in-depth; that our waste does not only end up in the air that we breathe, but also in the very populated hidden underworld of our lakes, rivers and seas, all very close to us, but perhaps often forgotten merely because we can´t walk on them.

Museo Aerosolar Reconquista

Story and impressions of the work process

By Carlos Almeida

At a time when our society is hurt and divided, the mottos: Work free from social and human borders and take advantage of the energy generated by community work, were good guides for the incubation of Museo Aero Solar “Reconquista”.

With these objectives in mind, a group of puppeteers and visual artists gathered in the academic space “Inflatable Laboratory”, decided to invite social groups that for some reason were exposed to different situations of social vulnerability to join the project.

We chose to express ourselves from what is usually considered as waste, from what is despised, from what does not manifest at first sight the possibility of becoming an artistic object.

Perhaps those who contributed most to making the construction of this great sculpture possible were precisely the people and groups in the most vulnerable situations.

Most of the bags that make up the Museo were rescued from the waste that arrives from Buenos Aires to the Bella Flor urban recycling cooperative, which is located in the town of José León Suárez, Buenos Aires. This highly contaminated and vulnerable region is called “Reconquista River Zone”, hence the name of our Museo.

In the same area of Reconquista River, very close to the facilities of Bella Flor Cooperative, is the North Penitentiary Complex, where the San Martín University Centre (CUSAM) is located. The CUSAM is a university centre dependent on UNSAM, where prisoners and prison guards can study together in an unprecedented experience. Women and men.

These two spaces, where daily life is very difficult to face, were the epicentres of the construction of the “Reconquista”. Approximately two hundred people have worked on the construction of the Museo:

  • Workers from the Bella Flor Urban Recycling Cooperative
  • Students deprived of their ambulatory freedom who are part of the CUSAM community
  • Teachers, students, graduates and management staff of the UNSAM Institute of Arts
  • Professors and students of the Institute of Architecture and Urbanism UNSAM
  • Teachers and young students from secondary schools in the area
  • People who independently joined the initiative by contributing bags
  • Recyclers, puppeteers, sociologists, anthropologists, circus artists, dancers, documentary makers, technicians, visual artists, philosophers, architects and enthusiastic people who joined.

We set out to build an Aero Solar Museo from the slogans generously shared by Tomás Saraceno and his team on Aerocene’s website. We set the objective of making the big sculpture by previously building a 300 square meter sheet, equivalent to a 10 x 30 meter rectangle, with bags or material that had already had some kind of previous use.

More than half of the material that makes up the Museo Reconquista was rescued from the mountains of rubbish that circulates daily in the facilities of the Bella Flor urban recycling cooperative. We also appealed to friends and family who would like to donate bags. We detected in our community that in general young people and teenagers do not usually keep plastic bags in their homes, it was easier to receive them thanks to the contribution of older people.

It is important to highlight that the workers of the Bella Flor Cooperative dedicated a lot of time, effort and joy in the recovery of bags for this purpose and they selected them thinking about the colours and formats that were most attractive to them for the construction of the Museo. After that enormous work they also spent several days cleaning and gluing bags.

Two special mentions are due to the plant coordinator Nora Rodríguez, who proposed the name “Reconquista” and considered that one of the activities to be carried out by the work cooperative was artistic production, because both she and her team had a lot to express from that place. The other special mention goes to Ernesto “Lalo” Paret, a great territorial articulator who understands and promotes expression through art in the processes of social reconstruction.


At this point it is important to mention the other driving idea of the project: The small, the oppressed, the individually and socially depressed can be transformed and generate a sense of expansion when they manage to take AIR in a communitarian way. We like the metaphor of the flattened Museo when it is placed on the floor before being set up, in relation to the air-filled, expanded, vital and moving Museo.

In order to make the 300 square metre sheet more concrete, we proposed to build, with each group that participated, sheets of approximately 50 square metres. Each day of work lasted approximately three hours and ended with a game of raising the newly constructed sheet of paper between all of us, bagging air and, when we came down, building a “bubble” where we all stayed inside and there… we sang, said poetry to each other, laughed and played freely.

Both the finished Museo and these previous instances of play are spaces of ephemeral habitability, meeting atmospheres, spheres of air.


Another slogan that crossed the construction process was that the participants had the possibility of writing, drawing and intervening in the sheets as they wished, expressing what they wanted, in absolute freedom, without any slogans and without any limits. This experience had its most impressive point in the CUSAM where the students deprived of their ambulatory freedom used the possibility of expressing themselves by writing on the plastic with extreme dedication, care and depth.

As the sheets were being built and reached our work base on the UNSAM Campus, the team of puppeteers and visual artists from the Inflatable Laboratory chair brought them together, trying to build a logic in the combination of colours, textures and written interventions.

The whole assembly process was guided by two models, one folded with the final shape of the tetrahedron and the other with the open rectangle and the possibility of observing it from both sides, which guided us to the position where each sheet could be placed.

These objects were very useful to explain to the people who joined the project what the final shape of the object we were building was going to be and it was also useful for the folding and final assembly stage.

The first assembly of the Museo was carried out inside a large circus tent that the University has on its Campus. We enjoyed living in and observing this wonderful and enormous object. That day, a cultural anthropology class was held inside the Museo and then we made the object independent from the air entry point so that the puppeteers could manipulate it from inside by means of some threads tied to the internal vertices and generate movements through the space. The object took on a life of its own… It was an incredible experience. That moment was very well recorded by Joaquín from Aerocene Argentina.

The first public and open-air installation was carried out in an open space on the Campus as part of the First International Congress of Art and Science “The Skies” organised by UNSAM. The following stagings took place on a rugby field located inside the prison complex, in a shed where the Museo was converted into a classroom for a philosophy class, and in other sectors of the Campus where it was set up for repairs.

The Museo Aero Solar Reconquista is a collectively owned object that will continue to receive the written interventions that the people who observe it or live in it wish to make and will remain available to the whole community to be mounted wherever a team of people has the desire to do so.

We know that a moment will come when the fragile material that makes up the object and requires permanent repairs will have already completed its life cycle. At that moment we will make a final survey of everything written and drawn on it and surely in some singular ceremony it will be given back to the Bella Flor Cooperative to enter a recycling process. It sounds sad… but we know that this material, added to the work of so many people, has allowed us to recycle and expand our emotions and our minds.

We thank Tomás Saraceno, Joaquín Ezcurra, Maxi Laina, Dalia Maini, Sasha Engelmann and all the aeronauts who through this open source initiative have inspired us and allowed us to go through some moments of our lives with a little less “gravity”.

Aerocene Futuros Posibles Tigre

El 13 de noviembre, Aerocene participó del festejo de los 130 años de la Escuela N° 8, Manuel Belgrano de Islas, fundada en el año 1889. También se celebró el día de la tradición y del isleño.

A partir de las 10 de la mañana fueron arribando las lanchas colectivas cargadas de chicos y maestros provenientes de distintas partes de la isla y de continente. Varias familias también llegaron en sus propias embarcaciones.

Cuando comenzó a sonar el himno, el primer globo Aerocene se elevó en el cielo flameando una wiphala, bandera del Estado Plurinacional de Bolivia como símbolo de hermandad con los pueblos andinos. Otro Aerocene voló con un gps para generar un aeroglifo, firma aérea en rechazo a los golpes de estado en América.


Durante el transcurso de la mañana se realizaron varias actividades. Guadalupe Boado de La Residuoteca junto con Ismael Romero Vargas de Agua alta dieron una charla sobre residuos y un taller de experimentación con botellas de plástico.


Mientras tanto, Amalia Boselli brindó un taller literario Futuro (s) posible (s) de “vuelo poético”, abierto a niñxs y adultos. A partir de cartas con  palabras o imágenes alusivas al aire/cosmos/planeta/viento/sol/agua que se hacen volar en una alfombra mágica y cual cadáver exquisito se propuso un juego de crear una historia colectiva para hacer volar en el globo hacia otros mundos posibles. La actividad que propone Amalia se trata entonces de un taller de poesía en vuelo que  invita, mientras los globos levantan vuelo, a levantar vuelo con nuestras imaginaciones.

La Comunidad del Sol

Fue un texto que salió de las cartas que le tocaron a Lucía, alumna de sexto grado de la Escuela N˚ 8.

Habitar dos  mundos.

Alrededor del mediodía comenzamos a inflar el Museo Aero solar creado por los científicos de IBYME, lo que generó momentos de gran alboroto y algarabía principalmente entre los más pequeños.

Finalmente, todos fueron embarcando una vez más para luego despedirnos desde las lanchas  hasta la próxima…

Movimento Ar livre! – Aerocene rising in São Paulo, Brasil

Join Aerocene!

On 20th October at 10:30 am, Aerocene Community will reunite in São Paulo for a collective action supporting climate change awa(i)reness towards a movement for free from fossil-fuel futures.

If the weather allows it – a sunny day and no winds – we will be ON AIR completely free of carbon emissions in front of MASP, Av. Paulista, 1578 – Bela Vista, São Paulo – SP, 01310-200.

Junte-se ao Aerocene! No dia 20 de outubro, às 10h, a Comunidade Aerocene se reunirá em São Paulo para uma ação coletiva em apoio a um movimento por um futuro sem combustíveis fósseis. Se o tempo permitir – um dia ensolarado e sem vento – estaremos no AR sem emissões de dióxido de carbono no vão livre do MASP, Av. Paulista, 1578 – Bela Vista, São Paulo – SP, 01310-200. São Paulo é uma cidade de recordes. Sendo a maior cidade do hemisfério sul e ocidental, sua geografia mudou tão rapidamente no século passado que por muito tempo foi impossível mapear sua extensão. Hoje a imigração tem taxas menores de crescimento do que no passado e o tecido urbano está se consolidando, o Google Street View explorou a maioria dos cantos da cidade, mesmo em áreas que a classe média considera muito arriscadas para uma caminhada. Todas as manifestações de um novo regime climático estão presentes aqui: o movimento pelo direito à moradia está crescendo; os processos de integração esbarram contra um quadro colonial muito presente e as políticas de bem-estar estão longe de ser um padrão. Não é de estranhar que o congestionamento urbano tenha produzido uma zona extremamente poluída, entre os vários índices alarmantes a mencionar está o das partículas em suspensão da poluição atmosférica, que se situa, em média, entre 20 e 25 microgramas por metro cúbico – mais do dobro do considerado seguro pela Organização Mundial de Saúde. Em todo o estado de São Paulo, a poluição do ar tem sido citada como responsável pela morte de cerca de 100 mil pessoas entre 2006 e 2011 por doenças respiratórias. No entanto, morar em São Paulo pode ser uma experiência agradável para quem consegue compensar o estresse da megalópole acessando as inúmeras estruturas – por uma preço – ou se permitindo uma melhor qualidade do ar através das experiências filtradas de construção equipada e carros refrigerados. Independentemente da origem social, viver em São Paulo significa confrontar-se com as consequências de um modelo de crescimento que requer uma enorme quantidade de recursos para manter um regime hiperconsumista. Quando essa voracidade encontra os piores programas políticos, alimenta uma extração irresponsável de recursos, um consumo selvagem e criminoso que consome em ritmo insensato um dos tesouros mais preciosos do Brasil — uma área natural impressionante que abriga comunidades indígenas que lutam para proteger a biodiversidade contra lucros privados e corporativos. Queremos decolar em São Paulo para ampliar nossos horizontes e ver o patrimônio natural acima da periferia urbana, pois o Brasil abriga 70% das espécies animais e vegetais listadas no mundo e é o país com o maior número de povos indígenas isolados. Aerocene vai flutuar no ar da cidade poluída para discutir um novo regime econômico que se opõe ao desmatamento amazônico e celebrar o grande esforço que as comunidades indígenas estão fazendo para proteger o ecossistema para todos nós.

If the weather allows it – a sunny day and no winds – we will be ON AIR completely free of carbon emissions in front of MASP, Av. Paulista, 1578 – Bela Vista, São Paulo – SP, 01310-200. São Paulo is a city of records. Being the biggest city in the Southern and in the Western Hemisphere, its geography has been changing so quickly in the past century that for long has been impossible to maps its extensions. Nowadays the immigration is not racing anymore and the urban fabric is consolidating, Google Street View explored most of the corner of the city, even in areas that the middle class would mark too risky for a night walk. All the amplitudes of the new climate regime is a real struggle here: the movement demanding housing for humans is rising (a fight for a very basic human right); integration seems to crash everyday against a still heavy colonial framework and welfare politics are far from being a standard. Not surprisingly the urban congestion causes an extremely polluted area, among various alarming indexes worth to mention is the air pollution particulates averaging 20 to 25 micrograms per cubic meter — over twice what is deemed safe by the World Health Organization. Across the entire state of São Paulo, air pollution has been cited as responsible for the death of nearly 100,000 people from 2006 to 2011 from respiratory illnesses. Living in São Paulo is a more pleasant experience to anybody that can compensate the stress of living in the megalopolis accessing the countless – paid – facilities, or granting himself a better air quality through filtered experiences in decent building and refreshed cars. Living in São Paulo means confronting – regardless the social extraction – with the consequences of a growth model that demands a massive amount of resources to maintain itself in obligation to consumeristic pledges. When hunger reaches the worst political agenda it fuels an irresponsible extraction of resources, a savage and brainless overconsumption that chew one of the most precious treasure of Brasil, an impressive area of natural area which is home of indigenous communities that are fighting to protect the natural biodiversity of their habitat against corporative and private profits. We want to take off in São Paulo to broaden our horizons and see above the urban outskirts the natural heritages as Brazil is home to 70% of the world’s catalogued animal and plant species, and the country with the largest number of uncontacted indigenous peoples in the World. Aerocene will be floating in the heavily polluted city’s air to discuss a new economic regime that stands against the Amazon deforestation and celebrate the great effort that the indigenous communities are doing to protect the ecosystem for all of us.
