Study of atmospheric condensers:
3.1 Inquiries:

• Library and literature research on ancient condensers and dew observations
• Discovery in 1993 of the Zibold condenser from the beginning of the 20th century (Feodosia, Crimea – Ukraine)
• Archeological excavation of tumuli (mounds) believed to be ancient condensers (Crimea, Ukraine)
• Study of the Knapen condenser at Trans-en-Provence (France)
• Thermo-physical data continuously recorded in the “Sainte – Tombe” at Arles sur Tech (France)
• Discovery in 2002 on the Vis island (Croatia) of the ruins of two dew condensers, erected by Klaphake (German scientist of mid-20th century)

3.2 Operations:

• Study of new materials to increase radiative cooling
• Study of the a erodynamics of condensers
• Numerical simulation of condensation
• Storage of dew in polyacrylamide gels
• Construction of a radiative condenser (scale model in Grenoble and Bordeaux, full size in Ajaccio – France, on the island of Biševo in Croatia and in Kutch – India)
• Chemical analysis of dew (Bordeaux, Grenoble, Ajaccio, French Polynesia – France)
• Study of the biological crust found in desert dunes (Negev, Israel)
• Set-up of a network of dew condensers in Israel and India
• Construction of dew collectors in Croatia, Ethiopia, Morocco, French Polynesia and India
