A Durable Superhydrophobic Interfacial Solar Evaporator Based on Metal-Phenolic Coordination Chemistry for Salt Resistance.

Summary: Making fresh water from ocean water using the sun is a great idea, but salt often clogs up the machines. Scientists have created a new, tough sponge that floats on the water and uses the sun's heat to make steam. It has a special coating that repels water and stops salt from building up. It heats up very fast, reaching 194 degrees Fahrenheit (90°C) in just over two minutes! This new sponge could be a huge step forward in easily making clean drinking water from the sea without breaking down.
