A number of apparatii for condensing water from the atmosphere are described, whereby atmospheric air is drawn through an enclosed space and moisture condenses on plates or similar contained within the enclosed space and subsequently collected. Most of the apparatii include means to increase the flow of air through the enclosed space to increase the efficiency of moisture collection. A typical apparatus includes a body (11) supporting condenser plates (15) of conical or frusto-conical configuration. Extractor fans, the operation of which are controlled by humidity sensing switches and temperature sensors, provide the increased flow. To promote condensation, typically, cooling ducts (49) are provided through which air-conditioned cool air is passed.
