This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

The specific device that mostly works by fanning in air that is cooled by using evaporation? Seems very similiar to what the ancient people there had.
They didn't have an AC compressor, refrigerant, etc. Their system stops working when your humidity is too high.
It works on the same physical principle, but they're still very different in their usage, side effects and limitations.
Well a significant difference is that this increases humidity, while normal AC decreases it.
