Contrary to what we all learned in elementary school science class, it turns out that heat may not be necessary to make water evaporate. Scientists at MIT have made the surprising discovery that light alone can evaporate water, and is even more efficient at it than heat. The finding could improve…
Anything clear should be about as non-light-absorbent as pure water. Glass, for example.
Or use a dielectric mirror and laser-light - so the overwhelming majority of monochromatic photons are reflected.
Interesting. Just not sure then why they need the extra polymers added. They should have at least done some rounds with just water.
I find it super fascinating that the most effective color happens to be that of chlorophyll.
