Sponge-like aerogel turns airborne vapor into drinkable water

Water security is a significant problem and pulling it out of the air, as fanciful as that may sound, is shaping as a potential part of the solution. A team from the National University of Singapore (NUS) has put forward a promising example of this type of technology, demonstrating a spongey aerogel that turns airborne water molecules into drinkable liquid, without needing a power source or having any moving parts.
