Scientists at the Ulsan National Institute of Science and Technology (UNIST) have developed the world's fastest oxide-based solar evaporator for seawater desalination, capable of producing approximately 1.4 gallons of freshwater per hour from a 1-square-meter surface. This innovative device, which utilizes a new photothermal material to absorb 97% of sunlight and achieves surface temperatures of 176°F, aims to combat water scarcity in remote communities and developing countries. The design's inverted U-shape and water-wicking fibers effectively prevent salt buildup, enhancing evaporation rates sevenfold compared to natural methods.
