An assembly extracts moisture from air for irrigation purposes. The assembly consists of a container system with two containers whose external surfaces act as heat exchangers, and the inner pressure of which is maintained at e.g. the night time condensation temperature of 10 deg C and 0.01227 bar. As a consequence of convection heat and radiated heat the daytime temperature reaches or surpasses 25 deg C, and the dry night time cooling of the lower chamber is used. The cooling raises the overhead condensation temperature within the system to a point at which the external air in contact with the upper container is cooled to the dew point, extracting water for drinking or irrigation purposes.
