Earlier quoted context omitted.

Depending on location, ground temperature tends to stabilize once you get a few feet down. Here in the northeast United States, it's about 60 F year-round once you get 15 feet below the surface. I worked for a company that was making direct-exchange geothermal heat pumps for homes - think about a big refrigerator whose coils are buried in the soil.

15 feet sounds pretty deep to dig to install something like this. Any idea what the temperature is like 2-4 feet?

It'd be good if this worked in warmer places like Australia, where you actually want to drink beer.

It might be a translation issue, but "well insulated" seems like exactly what you don't want for this sort of cooler. Maybe they mean the top is well insulated while the bottom is not.

$400?? That's insane.

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.
