Scientific & technical activities:

with the assistance of the French Atomic Energy Commission (CEA),
the French National Scientific Research Center (CNRS),
the French Institute of Research for Development (IRD),
l'Ecole Supérieure de Physique et Chimie Industrielles de la ville de Paris (ESPCI)
and the University of Corsica (France)

1. Areas of expertise:
1.1 Condensation phenomena: dew, frost, mist, etc.
1.2 Corrosion
1.3 Anti - dew

2. Dew formation study:
2.1 Measurements and experimentation (France - Ajaccio, Bordeaux, French Polynesia; Spain - Canary Islands; Croatia; Israel; Tunisia; Morocco; Mauritania; India; Australia; Chile)
2.2 Construction of a Dew Factory in India
2.3 Quantitatif evaluation of "Dew Mine" in France (R.O.R. Project)
2.4 Theory

3. 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

4. Education, Training:
4.1 Scientific formations:
university training courses, doctorate, post-doctorate
4.2 Supports of students and higt-school activities relative to dew

5. Projects:
5.1 Construction of a condenser in a arid zone of Burkina-Faso
5.2 Study of the dew water as an alternative water source in the Canarian Islands
