This is being misinterpreted here. They have found an unknown mechanism where water is absorbing light it would not absorb otherwise while in the boundary layer of a hydrogel and thus evaporating faster than it would if simply heated. If not a mistake or some unsustainable side reaction, this could mean cheaper things that require evaporation like desalination. A lot of people here though are saying it means things which would violate conservation of energy.
