How to build an evaporative cooler

I know that for many of us, it’s getting closer to fall, summer will soon be a distant memory… but I am still intrigued when I see innovative ways to cool our homes and ourselves. I found this easy to do DIY evaporative cooler while surfing the internet today. I like the quirky look of the offset holes in the orange 5 gallon bucket, and the industrial look of the curved elbow duct.

How to Build an Evaporative Cooler

How to build a low-cost 12 volt evaporative cooler.  My husband and I built two swamp coolers that we use to air condition our tent when we camp in hot, dry weather at Burning Man.  These compact units blow cool air like an air conditioner, but they use just water for evaporation instead of using a compressor or toxic Freon. There are two great designs on the internet for making evaporative coolers for camping.  This blog post enhances one of those designs by providing lots of detail on sourcing parts, comparing options for parts, and a variety of power options.  We built ours for under $40 each and they worked great for cooling a tent and letting us nap in the Nevada desert.
