A curious well, in the shape of a bell, allowing to collect condensation water in the arid zones, to discover.
In 1931, a Belgian engineer, Achille Knapen, had the idea of inventing this curious well to collect condensation water in arid areas. It consists of a bell made of limestone, 12 m in diameter and 12 m high. Under the bell, a sort of condenser with porous tubes carries the water into a cistern. According to the principle of condensation, due to the difference in temperature between day and night, dew droplets form inside the well and are then transported to the cistern. Ingenious!
