262 Critical perspectives on the use of technology for Peace: Papers Proceedings of the 23rd International Symposium on Electronic Art ISEA2017 Manizales 16th International Image Festival SOPRO (The Blow) Milton Terumitsu Sogabe, Fernando Fogliano, Fabio Oliveira Nunes, Soraya Braz, Carolina Peres, Cleber Gazana (cAt team). Universidade Estadual Paulista – UNESP Instituto de Artes – cAt team São Paulo, Brasil miltonsogabe@gmail.com Abstract This paper talks about “Sopro” (The Blow), an interactive work energized by the public through the force created by their blowing on a propeller. This art proposal is based on the use of a simple technological system, a poetics of the blow and on primordial scientiic principles. The system present in the work aligns itself with current energy and sustainability issues, inserting them in the context of art-technology, and post-digital thinking. Keywords Art-Technology, Energy, Blow, Sustainability, Post-Digital. Introduction This paper talks about “Sopro” (The Blow), a work carried out by the cAt (science/Art/technology) Research Group of the Arts Institute of the Universidade Estadual Paulista (São Paulo State University) - UNESP. We have been working with digital technology in art for long time, and in this work we make use of the thoughts present in the processes of creation with the digital, without employing digital technology. Questions regarding interactivity, collaboration, sustainability, post-digital and also a systemic vision, are present in the discussion process that generated “The Blow”. Figure 1 The Blow (2014). cAt Research Group Energy and Blowing One of the key issues facing us today pertains to our energy sources. Works in the art-technology ield can in a way incorporate this discussion and concern. In this regard, works that require energy can seek alternative energy sources as a more ecological manifestation (proposition). The work, “Sopro”, emerges in this context, searching for poetics in technology itself and its relation with the human being. In nature, the force of the winds is responsible for several modiications in the environment, such as the act of transforming the shapes of rocks by erosion, the movement of dunes in coastal areas and erosion processes. The processes whose geological agent is wind are called aeolian processes. The climate and its variations are directly related to the movement of the winds, which affect temperature and produce rainfall. These, in turn, transform nature and culture in cycles, like a living system. Given its strength, man has long sought to turn wind into useful energy, through windmills and sails in boats, and more recently through wind turbines that produce electricity. The so-called wind energy is considered an alternative energy source to fossil fuels and other forms that have an impact on the environment, being a form of“clean energy”. In common knowledge, the act of blowing is recurrently associated with the genesis of life. Different cultures in their cosmogonies, on explaining the emergence of man, involve a divine breath as an action capable of imparting life to what was formerly inert. In the well-known biblical passage from the book of Genesis, God blew the breath of life into Adam, the irst man. We ind a similar belief in Tupi-Guarani mythology, an important indigenous culture in South America. In their account, Tupã, the supreme divinity, would have breathed life into the human forms he modelled in clay during a ceremony. In Yoruba mythology from Africa, Obatalá,
