I hope you lack the time because you’re setting up your own study. This one was set up due to previous observations of rates of evaporation double or greater than those understood to be mathematically possible. Hell of an equipment error. It also observes a difference in the rate of evaporation under different colors of light, with the highest rate of evaporation occurring under green light, which you would probably also deem impossible, since color has nothing to do with it and green isn’t even the most energetic wavelength. An MIT professor, a postdoc, and four others hang their hat on these results, and the reality of this phenomenon. rdyoung disagrees with them in a comments section on an obscure forum. Which source might be more credible?
You also definitely don't understand what I or the study is saying. Not surprised here at all.
Again, as I said. Maybe we don't have the tech to read the miniscule amount of heat in a photon of light or the heat generated as the light excites the water molecules, that doesn't mean that heat wasn't a part of it.
Yet another one who has no idea or grasp of the concepts at play here.
Just like reddit, I thought a sub such as this would have a smarter community but once again you lot proved me wrong and showed me that no matter how dumb I think people can be, they can always surprise you with the idiocy.
I'll leave you with a quote from Harvey Danger.
Been around the world and found That only stupid people are breeding.
Just like Reddit you're being an absolute asshole for no reason.
Lighten up. This is no way to have a productive discussion. If you aren't in the mood, then maybe you shouldn't be commenting right now. Take a breather. We all have bad days. Hope you feel better.
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.
