Device and method for passive carbon dioxide collection with suspended sorbent disks

A passive carbon dioxide collection device, comprising:

• a release chamber;
• a capture structure coupled to the release chamber and comprising at least three straps and a plurality of disks coupled to and spaced along the at least three straps, each disk comprising a sorbent material, the capture structure being movable between a collection configuration and a release configuration, and each strap comprising a primary width and a secondary width, the secondary width at least an order of magnitude smaller than the primary width;
• a movable portion configured to move the capture structure between the collection configuration and the release configuration;
• wherein the collection configuration comprises the capture structure extending upward from the release chamber, the plurality of disks suspended from the movable portion by the at least three straps such that, for each pair of neighboring disks of the plurality of disks having a lower disk and an upper disk and for each strap of the at least three straps the lower disk is separated from the upper disk by a connecting segment of the strap, exposing at least a portion of the capture structure to an airflow and allowing the sorbent material of the plurality of disks to capture carbon dioxide;
• wherein the release configuration comprises the plurality of disks being stacked entirely within the release chamber for regeneration resulting in the release of the carbon dioxide sorbed into the sorbent material, each strap of the at least three straps being collapsed, each connecting segment having assumed a release topology, the release topology sized and positioned to accommodate the stacking of the plurality of disks entirely within the release chamber;
• and
• wherein, for each pair of neighboring disks of the plurality of disks and for each strap of the at least three straps, the connecting segment is biased to move toward the release topology when the lower disk is not entirely supported by the at least three straps.
