Scientists have taken inspiration from roses to develop a low-cost device for collecting and purifying water, that could provide a portable source of water for homes in remote locations. The flower-like structure, developed at The University of Texas in the US, can produce more than half a gallon of water per hour. The team developed a new approach to solar steaming for water production that uses energy from sunlight to separate salt and other impurities from water through evaporation. In a study published in the journal Advanced Materials, they outline how an origami rose provided the insp...
