Ancient Greek installations in arid climates, such as Theodosia in the Crimea, by which dependable amounts of potable water could be obtained from atmospheric vapor, offer proof of the possibility and effectiveness of air as a secondary source of water supply. The discovery of Theodosia's ancient aerial wells indicate that the process of drawing water from atmospheric water vapor was practically managed over 2000 years ago. Chaptal's experiments confirmed that, under certain conditions, it is possible to obtain rather large quantities of liquid water by means of an above-ground aerial well. Knapen demonstrated the need to carefully accommodate the type and construction of an aerail well to the local climatological and meteorological conditions. The results of Godard's experiments with a captor placed in the ground and flush with the ground surface were negative. Theoretically, it should be possible, under proper conditions, to obtain quantities of water from the air by condensation to satisfy the reasonable needs of small units of consumers. Thus, it seems that the ideas on secondary moisture sources and on aerial wells developed in antiquity are of too great importance to be forgotten by the engineering profession. Contrary to some published reports, no aerial well at Montpellier or Trans has functioned in modern times. But the wells of Theodosia are, in their ruined state, silent witnesses of an era of certain scientific known-how which, with patience and perseverance, might be recaptured with great benefit. /Author/
