I'll be living on a stretch of my uncle's land this summer, a few miles from the [dirt] road. Way out, no electricity, in a small shack. One of my biggest concerns is refrigeration of meat and milk, and I'm working on a solution that doesn't involve electricity, propane, or ice. I've looked in the the Nigerian Zeer (terra-cotta pots and sand), but I got another idea. If I used an odor-proof sack held under spring water by a system of nets, my meat would stay cold and useable for a week or two. The Loksak Opsak seems like just the kind of thing I could use, but there's one issue. Its description says that it's submersible to 200 feet, but nowhere have I read of this being tested. Can anyone shed any light on this subject here? I've read that the ziplock aspect of the bag is rather loose and only single track, leading me to believe that it might come loose under pressure, thus exposing my meat and milk to the water and so forth.
Can anyone help me out here?
