- hdjrudni 2mo agoDoesn't that imply you're losing water?
- cannonpr 2mo agoYes you are losing water but the phase change energy of water is immense, very little needs to be evaporated comparatively for immense cooling.
- WJW 2mo agoYes it does. But it might be worth it if you have more water than cooling capacity, or if you have an otherwise very dry house that you'd want a little but more humidified.
- ASalazarMX 2mo agoGrandparents used to have this. The outer surface of the pot is detectably moist, but not by much, the water level wasnt noticeably lower by the end of the day, I'd say much less than a single cup. Their climate was very dry, crack-your-skin-dry, I don't think it would work as well in a humid environment.
- thesz 2mo agoThe cooler water gets, the less vapor it creates.
