Starting from the Easter week there wil be an exhibition  “Green room” at Technical University of Stockholm - Rasa Smite and Raitis Smits will present “Biotricity” - the starting project of “Pound battery”. It will be accompanied by lecture about art and science cooperation and “Biotricity” creative workshops. In workshops, participants will be able to create their own bacteria battery and get acquainted with two points of this innovative technology – scientific and artistic. Also, participants will be introduced with “Biotricity” installation data sonification and visualization processes.

Biotricity sonifies the process of generating electricity from bacteria living in pond and lake, or in common, everyday waste water. The microbial fuel cells is the next-generation bio-technology that converts chemical energy to electrical energy by using microorganisms – bacteria found in the dirty water. Someday, this technology could be used to upgrade waste treatment facilities into power plants producing renewable energy. The networked sound & bio-electrical installation consists of a “bacteria fuel” cell network altogether creating a mini bacteria-power station. Continuous measurements deliver audible and visible impressions of this form of electricity generation by micro-organisms, and of its fluctuations. Thus the “bacteria fuel” process is interpreted in video and sound structures providing an aesthetic perspective on the interaction between nature and technology, biologic systems and electronic networks, biology and computing.

The newest version of Biotricity installation consist of a double cell “bacteria battery”, live stereo-sound (on headphones) that sonifies fluctuation of bacteria's generated electricity, and a video (made from the images taken with electronic microscope that shows bacteria environment), which simultaniosly with the sound creates real-time visualizations of bacteria activity (by “glitching” the video images).
