Abstract

A device and method for passive collection of atmospheric CO2 is disclosed. The device includes a chamber having an inner wall, an outer wall, an annular void between the inner and outer walls, and a sump connecting the annular void and an inner cylinder. The device also includes a capture structure having a sorbent material and movable between open and closed configurations. The device includes a water delivery device with a pump and a water applicator positioned within the annular void to dispense water onto the outer wall. The pump transfers water from the sump to the applicator. The open configuration includes the sorbent exposed and allowed to capture CO2. The closed configuration includes the capture structure being enclosed inside the chamber such that a heated water vapor releases captured CO2. The vapor is created by the solar heating of the outer wall and the water dispensed within.
