We identified overarching patterns among the researched biological strategies which inspired us to design a panel system that can be applied on multiple scales to buildings and other existing infrastructure along freeways and main streets.Our 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 including the mesh at the inlet, the strips themselves, and along the interior walls of the tube 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.
