This sun-powered sponge pulls drinking water straight from the ocean

In a leap toward sustainable desalination, researchers person created a solar-powered sponge-like aerogel that turns seawater into drinkable h2o utilizing conscionable sunlight and a integrative cover. Unlike erstwhile materials, this caller 3D-printed aerogel maintains its ratio astatine larger sizes, solving a cardinal scalability issue. In outdoor tests, it produced cleanable h2o straight from the water without immoderate electricity, pointing to a aboriginal of low-cost, energy-free freshwater production.
