COSMO, PS1 Pavilion

The design takes off from a statistical fact: in 2015, two-thirds of the world’s population will be living in countries suffering scarcity of water resources. Conceived as a theme for ecological and political reflection, water is the main subject of Cosmo, an artifact stimulating thought about the consumption and management of such a scarce good, and at the same time a ludic machine for social interaction.

Mobile and collapsible, the pavilion is an assemblage of components of standard irrigation systems, connected to a pump that makes the water pass through a succession of natural filters. Taking advantage of processes like photosynthesis and digestion with vegetation, these filters eliminate pollutant particles from the water, besides balancing its pH and increasing the amount of oxygen in it. The system makes it possible to cleanse 3,000 gallons (approximately 11,300 liters) of water every four days. At the end of the process, the liquid circulates anew, in such a way that, in the course of time, it is increasingly pure.

The artifact will in real time be giving information about the process through its digital connectivity, but also in analogue form. Its nucleus, built with a plastic grid, will light up progressively, in accordance with increasing levels of purity of the water treated in this small social machine.
