Abstract: A system and method for passive collection of atmospheric carbon dioxide is disclosed. The system includes a harvest chamber having a first opening and a sorbent regeneration system. The system also includes a capture body coupled to and movable by a support structure. The capture body includes a sorbent material and is movable by the support structure to be in a collection configuration wherein at least a portion of the capture body is in contact with a natural airflow outside the harvest chamber such that atmospheric carbon dioxide is captured by the sorbent material, and a release configuration wherein at least a portion of the capture body holding captured carbon dioxide is operated upon by the regeneration system inside the harvest chamber such that captured carbon dioxide is released to form an enriched gas.

Abstract: A device for passive collection of atmospheric carbon dioxide is disclosed. The device includes a release chamber having an opening and a sorbent regeneration system. The device also includes a capture structure coupled to the release chamber, having at least one collapsible support and a plurality of tiles spaced along the collapsible support. Each tile has a sorbent material. The capture structure is movable between a collection configuration and a release configuration. The collection configuration includes the capture structure extending upward from the release chamber to expose the capture structure to an airflow and allow the sorbent material to capture atmospheric carbon dioxide. The release configuration includes the collapsible support being collapsed and the plurality of tiles being sufficiently enclosed inside the release chamber that the sorbent regeneration system may operate on the plurality of tiles to release captured carbon dioxide from the sorbent material and form an enriched gas.
