This aerogel and some sun could make saltwater drinkable

A novel aerogel from Hong Kong Polytechnic University researchers could transform saltwater desalination. The solar-powered material efficiently converts seawater to freshwater, potentially addressing global water scarcity. Unlike previous methods, this aerogel maintains performance at larger scales due to its porous structure. With only 0.3% of Earth's water readily drinkable and over 2 billion people relying on contaminated sources, this innovation could provide a sustainable solution to the global water crisis, especially in regions lacking clean water access.
