The following two Images are a detail of the cascading bio filter system. Expanded clay pebbles provides a surface for the necessary fungi and bacteria to process fish waste to free nitrogen. This nitrogen becomes nutrients for the duckweed which is then food for the fish.
MINOE’s Loop is a sculptural illustration of a union between nature and technology. This kinetic work portrays a mobile aquaponic ecosystem driven by an autonomous line following robot named MINOE (Mobile Implement Nurturing Organic Equilibrium). The project whimsically combines natural biological processes with the systemic functionality of a machine. MINOE labors to sustain a balance in a fictional system where technology mimics natural processes.
MINOE is programmed to follow the white line on the floor and make two stops. Fish wastewater is delivered to the top of the river cascade and filtered through pools of duckweed and clay pebbles. The waste provides vital nutrients to the duckweed, which in turn creates food for the fish. The tank refills with filtered water and loops back to repeat the cycle.
