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.
Wind powered swamp cooler. Basically a humidifier, but it does lower the temperature. I've heard people call swamp coolers air conditioning, so I don't think it's wrong.
No, calling swamp coolers air conditioning is definitely wrong.
If it's 100% humidity in your room, the swamp cooler is going to do absolutely nothing, but AC will cool it down and can even dehumidify a bit if you run it enough.
Swamp coolers are awesome, but they only work in dry climates unfortunately.
