Researchers at MIT have developed an extra-absorbent hydrogel that can draw water from the air, reports Ross Cristantiello for Boston.com. The new hydrogel “could potentially help communities ravaged by drought and make air conditioners more energy-efficient,” writes Cristantiello.
MIT researchers have found that when enhanced with salt, a rubbery hydrogel commonly found in diapers can absorb record amounts of moisture from the air, reports Andrew Paul for Popular Science. “Across a wide variety of humidity conditions, the team’s enhanced hydrogel could swell and absorb impressive amounts of air moisture without leaking,” Paul notes.
