Scientists built a wood-based sponge that pulls water from air as dry as 15% humidity; it produced up to 1.72 litres per kg per 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.
