moisture farmers ou puit aerien

Around 1900, a Russian engineer by the name of Friedrich Zibold made the conjecture that ancient structures found on Greek outposts on the Crimean Peninsula were a sort of air-well, designed to harvest enough moisture from the atmosphere to sustain a small settlement. Despite initial successes with models based on the Greek buildings, Zibold was unable to sustain the condensation and collection of water for very long.  Later archaeological studies determined that the mysterious structures were actually burial mounds (this being around the time when interests were captivated by the idea of the Ark of the Covenant as a battery and the death ray of Archimedes), but that did not dissuade others from trying to build their own air-wells after Zibold’s calculations.
One such hive-like well (puit aerien) was erected in Trans-en-Provence in the 1930s (reportedly, a UFO scorched the fields of this community in 1981) in the département of the Var by Belgian inventor Achille Knapen. The site was abandoned when it also failed to collect water in the expected volumes, but this early experiment helped engineers build better and functional condensing units that help supplement the rains in places all around the world today.
