Swamp coolers are not new. They have been around for years. You may know them by another name, Evaporative Cooler. One major draw back of evaporative cooling is the added humidity. The desert southwest is the perfect place for this type of cooling. Here is a great link for background on this type of cooling.

Evaporative Cooling

An added benefit of evaporative cooling is that it works best in the hottest time of the day. As the temperature outside increases as the sun climbs, the humidity normally drops. In the early morning, for example, the temperature may be 70 degrees, with a relative humidity of 60 percent. By mid-afternoon, when the temperature has climbed to 90 degrees, the humidity may well have dropped to 30 percent – conditions that make evaporative cooling work more effectively.

I am sure there are more. One interesting item to note is that Coolerado unit does not add humidity to the cooled air. This makes it suitable for any environment. So they say. I don’t think it would work great in Florida, but that is just me.
