Yea, I wonder how long it takes you to make your money back on the fridge savings. Good conversation topic at least for the BBQ's.

  I imagine it would be most useful for people who camp without electricity often. However dry ice is very cheap (like $1/lb cheap) and more convenient (you don't have to dig a hole) so unless you are camping very often or camp for very long periods of time, it would probably take a very long time to break even. It is a pretty cool idea though, that alone could justify part of the price for some people.

    campers? So dig a whole new borehole each time you want to use this? I've never dug a mini-mineshaft before, but isn't that prohibitive amounts of effort ?

      It doesn't seem like it would be too bad. If they are in the same spot for two weeks or so then I think it might be worth it. For a week or less then a traditional cooler with dry ice seems like it would be clearly better. The type of soil (rocky or not) would make a big difference. Though icy ground where this would work best would be the hardest to dig...
