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

In a leap toward sustainable desalination, researchers have created a solar-powered sponge-like aerogel that turns seawater into drinkable water using just sunlight and a plastic cover. Unlike previous materials, this new 3D-printed aerogel maintains its efficiency at larger sizes, solving a key scalability issue. In outdoor tests, it produced clean water directly from the ocean without any electricity, pointing to a future of low-cost, energy-free freshwater production.
