Missing from the article is the size/density of the material required to achieve several liters of collected water. Judging by the porous nature of the material, it might require fairly large collectors, e.g. 10x10 meters. If the material is manageable at these large sizes, then it would be like a giant flag or sail flapping in the breeze, that hopefully the wind won't rupture or damage. Then for harvesting the water... you'd roll it up and squeeze it in a heated chamber? There are other technologies coming online for capturing water in arid conditions, for example the condenser device developed a couple of years ago at Technion in Israel [1]. Still, it's quite intriguing especially given the simplicity and low cost. 1. https://www.israel21c.org/israeli-scientists-generate-water-from-air-even-in-the-desert/ https://www.israel21c.org/israeli-scientists-generate-water-...
