Also known as an , this structure collects water by promoting the condensation of moisture from the air.

In architecture, an air well is an unroofed internal space or "light well" within a building designed to provide to inner rooms.

: Modern devices that use energy (like a dehumidifier) to cool air and collect water.

An can refer to two very different things: a structure designed to extract water from the atmosphere or an architectural feature used for natural ventilation and lighting . 💧 Air Well (Water Condenser)

: It uses natural temperature differences to cool humid air until water droplets form (similar to morning dew). Designs :

: Massive stone structures, like the famous 1931 Achille Knapen well in France, designed to stay cool during the day.

: While historical "dew towers" often had low yields (only a few liters a day), modern low-tech condensers are more efficient. 🏠 Air Well (Architectural Feature)

: Uses lightweight surfaces that cool quickly at night by radiating heat into space.
