You will find the second law of thermodynamics very disappointing.

Assuming the system is exposed to open atmosphere, and knowing that free electrons have higher energy than bound electrons, it's not clear what you're trying to imply here. Especially since entropy increasing only applies to closed systems.

      Not OP, but I'm not sure what you're trying to imply...going from liquid to gas phase change is going from lower entropy to higher entropy. There is no laws of thermodynamics being broken. And for your note for closed system, control volumes are defined as the system you're looking at. There is no "scale" when it comes to it (whether your control volume is the Earth, universe, or your room). Laws of thermodynamics cannot be broken regardless of your control volume size (as long as you obey the continuous limit theorem).

      Evaporative cooling doesn't lower the entropy (oh I'm so anxious!), and also doesn't work outside of very few regions. If you're suggesting running a humidifier and then generating electricity off the temperature difference I have a crazier suggestion - run your thermocouple between something in direct sunlight and the shade. Or an extreme example known as a solar cell.

I am merely pointing out the absurdity of arguing that entropy increasing globally means that cooling cannot occur locally. > an extreme example known as a solar cell If you think solar cells operate via temperature differential, I'm just going to go ahead and end this conversation before I say something ugly about people who don't know things trying really hard to look like they do know things.

Perhaps you're right and the person really said something dumb, but perhaps they didn't. By applying the principle of charity you'll not only avoid being unnecessarily rude towards people but also open avenues for better communication and possibly even learn something
