Light can make water evaporate without heat

https://news.mit.edu/2023/surprising-finding-light-makes-water-evaporate-without-heat-1031

Summary: MIT researchers have discovered that light can directly cause water evaporation without the need for heat, a phenomenon they call the "photomolecular effect." This finding could improve the efficiency of solar-powered desalination systems and impact climate change modeling. The effect occurs at the interface of water and air and is more efficient than heat-induced evaporation.
