Pffft! Just drink it warm. Cold beer is for poofters who don't really like the taste of beer.

AFAIK, the ground temperature will be the average air temperature over the year. It's certainly not 58F everywhere, because in Siberia there's permafrost, and in Denmark might likely be less than 58F, too.
Based on quick search, the average air temperature in Denmark is 8-9°C(46-48F)[1]. I suspect that you don't find that cold ground temperatures though. I found some local statistics about ground temperature[2], which shows that even around here the invention would barely work in the warmest months. And I'm living nearly thousand miles northwards from Denmark, from the same source the average air temperature here is -2…

That's far north... Tromsø? Kirkenes?

Mmmm. 80 degree beer :) Florida pools get very warm.
I got it: build a soda dispenser like in the OP, except make it fill with rainwater, and insulate it. Assuming the rainwater is cooler than the ambient air it should keep the cans cool without requiring power. As a side thing you could attach either solar or wind-power to a peltier to cool the thing even more.
It's tangentially related, but my grandfather used to tell me stories about growing up in Florida in the 30s. He and his brothers used to homebrew beer, and in order to keep it cool while it fermented (and hide it from their parents), they'd burry the barrel in the side of a ditch.

#65It's showing that it's only being used with cans, instead of bottles.

#66That looks cool. But I live in Southern New Mexico.
The soil temperature here gets very hot and isn't near beer cold even 3 feet down. Perhaps I could still use one of these though. As an eco-friendly coffee warmer. Fill it with canned starbucks and off we go!

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 ?

Close but wrong side of the border :) I'm currently (stuck) in Ivalo[1], family home is in Utsjoki
