Zainab Nathani, a high school junior from Niles, Illinois, has designed a material that can pull drinkable water straight out of humid air, powered entirely by sunlight. Studying at Niles Township West High School, she built her project around emulsion-templated composite biogels, porous, bio-based structures engineered to trap moisture from the atmosphere and release it as liquid water once warmed by natural sunlight, with no electricity or added energy required.
