Lorsqu'il s'agit d'efficacité, la nature est souvent bonne conseillère. Et c'est une fois de plus ce que démontrent aujourd'hui des chercheurs américains. Ils se sont inspirés de scarabées, de cactus et d'herbes pour imaginer des surfaces biomimétiques, capables d'extraire de l'eau potable de l'air du désert.

[Image] "Darkling beetles (family Tenebrionidae) of the Namib Desert, located on the southwest coast of Africa, live in one of the driest habitats in the world. But some species of Darkling beetle can get the water they need from dew and ocean fog, using their very own body surfaces. Several researchers are studying the beetles, as well as synthetic surfaces inspired by the beetle’s body, to uncover the roles that structure, chemistry, and behavior play in capturing water from the air."
