    Wondering if anyone else is using or built a Zeer Pot for Boondocking and what your experiences are with one. For those that don't know, they are a passive cooling system using evaporative cooling with two clay pots, sand, water, and a thin towel covering. With great success and satisfaction, I have two I take along and I can keep vegetables and fruits for more than a week, but I usually eat them first. Google for plans, very simple.

    Very cool concept. Looks like a great, energy-free way to extend the life of those fruits and vegetables. I'll think I'll keep the beer on ice though.

    Here is one site dedicated to making the Zeer Pot system.

    http://www.instructables.com/id/A-Practical-Zeer-Pot-evaporative-cooler-non-electr/

    I found an 18 inch and 14 inch pot for under $40. Nice fit with good spacing for the effect you need. I bought an indoor outdoor thermometer to experiment with location. Having it exposed to the wind, and obviously out of direct sunlight is a key. Once you add the sand it is actually a little heavy, heavier than I anticipated.

    Well I used the Zeer Pot in Wyoming for 2 months with great success keeping my eggs, vegetables, fruits cool to about 50-60 degrees when it got up to 80 degrees outside. The key was keeping in a shady, windy location, and always re hydrating the sand. Low humidity in WY helped. Never work in a state like Florida or Georgia. I plan to build a different type of evaporator cooler, more like a tee-pee design and burlap with a constant water source. When I get a working design I'll post.

    Coleman coolers with ice work real well to keep things chilled. Just saying [;)]
