A passive water harvester based on MOF-303 has been designed and configured to achieve the highest efficiency among passive designs. A water harvesting capacity of 285 g H~2~O per kilogram of MOF-303 per day with only ambient sunlight and no power or other energy input was achieved. The MOF cartridge design and the condenser surface treatments were key features in achieving high water harvesting efficiency especially when tested in the field (Death Valley National Park).
It’d be really nice if people actually read the article instead of just assuming they already know everything.
