Jelaskan =Panén jieunan dari Ibun dalam bahasa sunda

Several man-made devices such as antique, big stone piles in the Ukraine, medieval "dew ponds" in southern England, or volcanic stone covers on the fields of Lanzarote have been thought to be dew-catching devices, but could be shown to work on other principles. At present, the International Organization for Dew Utilization is working on effective, foil-based condensers for regions where rain or fog cannot cover water needs throughout the yéar.

An interesting strategy for harvesting dew on large scale for drinking water was proposed in 1980.
