Abstract

A passive COcollection device is disclosed, including a release chamber and a capture structure having at least three straps and a plurality of sorbent disks coupled to and spaced along the straps. The capture structure is movable between collection and release configurations. Each strap has a primary and secondary width, the secondary width smaller than the primary. The collection configuration includes the disks suspended from a movable portion by the straps such that, for each pair of neighboring disks and for each strap, a lower disk is separated from an upper disk by a connecting segment, allowing the sorbent to capture carbon dioxide from an airflow. The release configuration includes the disks being stacked within the chamber for regeneration. Each connecting segment is in a release topology designed to accommodate stacking the disks within the chamber. The connecting segment is biased to move toward the release topology.
