1. A housing comprising at least: a first opening for ambient air to enter the housing; a second opening for a coolant from a base station to enter the housing; a third opening for the coolant to exit the housing, wherein the third opening is below the second opening; at least one pipe forming a first cooling route to cool the coolant between the second opening and the third opening, wherein the at least one pipe forming the first cooling route is a partially insulated pipe with an uninsulated pipe surface portion; at least one disc made of a solid carbon dioxide sorbent material for capturing carbon dioxide from the ambient air, the at least one disc being arranged in the housing within the first cooling route with a direct physical contact to the uninsulated pipe surface portion for heating the at least one disc when the coolant passes the first cooling route; a fourth opening for air to exit the housing, wherein the fourth opening is below the third opening and the at least one pipe; and a fifth opening for a carbon dioxide gas to exit the housing, wherein the fifth opening is below the fourth opening.
