Radiative cooling is the phenomenon responsible for dew formation on plants Harvesting humidity from the air has two different pathways fog and dew but harvesting dew have not been sufficiently exploited In this paper we describe the resources for radiative cooling as well as lawsonite mineral for exploiting this natural phenomenon Further this paper describes the development of dew harvesting systems for use in the semi-arid mirleft south Morocco Numerical simulations using the energy balance equation were performed Harvesting dew can be used as a renewable complementary source of water both for drinking and agriculture in specific arid or semi- arid areas In order to form global estimates of dew collection potential via a dew formation model we combined meteorological parameters with radiative properties of a specific collector sheet natural lawsonite CaAl 2 Si 2 O 7 OH 2 H 2 O deposited on glass to enhance the dew yield The daily yields show that significant amounts of dew water can be collectedDownloads
