Transparent wärmegedämmter Solarteich

Since January 1989 a transparently insulated solar pond (1300 litres, 25 square centimetre water depth) has been investigted. The experiments aim at the application of solar ponds at operation temperatures around 80 degree C in sunrich areas, for example as continuous, day and night source of thermal energy for seawater desalination by membrane distillation.
