Obtención de agua potable por métodos no tradicionales

Fresh water is a scarce resource on a planetary basis. There are, however, freshwater sources still to be tapped. In this paper we review work that's being done to capture freshwater from dynamic fogs or "camanchacas". We first present the conditions that promote the formation of these fogs and the different studies conducted since the early sixties to trap water. In the projects under review we briefly present the work that was done by the Universidad Católica del Norte (Antofagasta, Chile) and the more recent work done by Pilar Cereceda and Robert Schemenauer in "El Tofo". The paper ends with a brief analysis of the future perspectives of this water source.
