Scientists built a sponge pulling water from dry air; yields 1.72L per kg/day

Scientists have engineered a groundbreaking wood-derived material capable of extracting water from arid air, effectively capturing moisture even at humidity levels as low as fifteen percent. Featuring a solar thermal storage component, it enables water release under dark conditions. Field experiments yielded substantial quantities of potable freshwater daily, signifying a revolutionary advancement in atmospheric water collection.
