Forget billion-dollar desalination plants, complex filters, or energy-hungry infrastructure. The next revolution in clean water might just come from a 3D-printed sponge and the sun.
In a radical leap forward, researchers at the American Chemical Society have developed a lightweight, porous aerogel that turns salty seawater into fresh, drinkable water using nothing more than natural sunlight and a curved piece of plastic. No electricity. No pressure systems. Just a sun-powered sponge that could fit in your backpack—and possibly save millions.
