Turning ocean water into pure drinking water sustainably.

A discovery using seawater has pushed science closer to solving one of humanity’s oldest problems, access to clean and affordable freshwater. Researchers have developed a sunlight driven system that purifies ocean water without electricity or heavy machinery, marking the first time seawater itself has played such an active role in a scalable desalination process. The result is a self powered sponge that uses solar energy to separate salt from water while leaving behind only trace residues. It is simple, renewable and potentially revolutionary in areas where freshwater is scarce. Here is how this breakthrough actually works.
