Paper If I understand correctly, it relates to light’s behavior as both a particle and a wave. Photons can “shave” molecules off the surface of water, creating vapor.
The effect apparently peaks around 520 nm (the visible color cyan, which has lower thermal absorption) and at an angle of 45 deg. Would these results suggest it’s actually possible to induce evaporative cooling with the careful application of light?
I wonder if it could be used to improve desalination techniques.
Was fully prepared for the answer to this to be that a couple extra molecules evaporating don’t make a big difference, but:
That sounds legitimately exciting!
