You replied to a fairly accurate summary of the postulated explanation of an observed phenomena by saying it’s literally impossible. Either the study is faking its* data, or the study has real data but you don’t like the way definitions are playing out here. You’re arguing for both, because it’s really important that this study is wrong, because you don’t like it. But it can’t be both. Let’s assume PNAS didn’t publish a completely fraudulent study about a made-up phenomenon.
The thermal heat that is being transferred is what causes evaporation. That’s the historical understanding. Yes? Energy in, energy out. 1:1 ratio, everything is conserved. But it’s evaporating twice as fast as that measured heat transfer explains. 1=2? That’s not right. Saying “it’s just more heat that you can’t measure” doesn’t make any sense, because you’re claiming that 1.0004 = 2. It’s a new process. Yeah, something happened on a molecular level and there was probably heat transfer. But on a completely different scale than the known process of evaporation through actual ‘macro’ heat transfer. So it’s not the fucking same.
Again, the green thing. If evaporation is caused only by previously understood processes of heat transfer—more energy is more heat transfer is more evaporation—then why does a less energetic green light produce more evaporation than a more energetic blue or violent light?
“The researchers tried to duplicate the observed evaporation rate with the same setup but using electricity to heat the material, and no light. Even though the thermal input was the same as in the other test, the amount of water that evaporated never exceeded the thermal limit. However, it did so when the simulated sunlight was on, confirming that light was the cause of the extra evaporation.”
Sorry to steal so much of your time, but if you’re not fucking what’s so damn important
Don't feed the troll.
