Kristin Fauske, Architecture Major, and her two team members from California Polytechnic State University San Luis Obispo, won first place in the Biomimicry Global Design Challenge, with their project CO2 extrACTION.
CO2 extrACTION is a multi-functional panel system that works to capture and isolate airborne carbon dioxide in dense urban areas.
Kristin and her team researched 40 biological examples capturing carbon dioxide and identified overarching patterns among the researched biological strategies which inspired them to design a panel system that can be applied on multiple scales to buildings and other existing infrastructure along freeways and main streets. Their design creates a way to facilitate the extraction of airborne carbon dioxide by drawing it through reed-like entrances and exits. Each inlet uses the venturi effect to increase air speed coming into the system. The air then passes through a carbon scrubber, which contains polymer strips coated with anionic exchange resin. The resin reacts with atmospheric carbon dioxide, converting it to bicarbonate. The carbon dioxide is stored on the strips until they are rinsed with water or moist air, which occurs naturally around dawn when atmospheric water condensation accumulates on multiple components of the structure. The carbon dioxide is then released and drawn into the chamber below, where it is stored and transported via a tube to another location for further use.
They have been invited to continue working on their project in the Biomimicry Institute’s Accelerator Program. Kristin also received a department award from California Polytechnic State University for this project.
Congratulations Kristin, on all of your accomplishments!
