This is a #BigFuckingDeal!!! Water from the air with low energy & low long-term operating costs!!! People I met (engineers & computer scientists) in the late 1990s from the #MiddleEast told me they (and many others since then) thought the next World War would be over #Water! One guy said they were welling up so much drinking water that the desert floor dropped closer to Sea-Level!!! That's a problem that Mexico City also experienced! Desalinization of ocean water isn't easy. This solution appears to be easy and efficient (unless some rare-earth materials are in short supply to produce the panels).
