Pond Battery (2015) by Rasa Smite and Raitis Smits visualizes more contemporary ways of energy production. The electric sound intervenes the seemingly idyllic landscape after the artists installed six microbial fuels in the pond of the Botanical Garden of the University of Latvia in Riga. Images of the measurements of bacteria’ electrical fluctuations were used to make the invisible activity visible and audible. A process of the generation of electricity was translated into live sound and image structures, providing an aesthetic perspective on the interaction between nature and technology, ecological systems and electronic networks, human and micro-worlds. The collected data from the seven-month long observation period is the footage and sound for the structural film and creates a sensual and emotional experience—a poetics of green energy.
