That's the exact opposite of extracting moisture from the air.

You're right. I'll leave my original comment because I'm an idiot, ha ha.

Running a swamp cooler + dehumidifier that doesn't heat up would mean being able to do self contained cooling which would be a massive thing. Currently the only way to do that is with desiccant which needs recharging too often to be practical.
