A group of Danes trying to save the word while keeping their Carlsberg cool have come up with a rather useful Green innovation. Earth cooled beer. This completely off grid solution is designed for the backyard patio or garden, relying on a hand crank to move beer from Mother Earth to the imbiber. The group's slogan is Save the world one earth cooled beer at a time and promotes itself with the testimonial "eCool is the greatest gift a man could wish for". No wonder the group can't keep up with demand.
I suspect between Danish love of the outdoors during the summer time, and drinking beer, this is going to be a hit. Hard to say how it'll do outside of Denmark but I have this strong desire to find out if the $350 price tag includes shipping to California.

That's not true. There is no "free cold" to be had. Every warm can of beer you put in there, costs a certain amount of electricity. You won't notice it, immediately, as there's so much chilled thermal mass in there that the only symptom is compressor kicking on a fraction of a second sooner than it would without those few warm cans. On a larger scale, with a 36 pack of warm beer/soda cans, you'll find your refrigerator thermostat trips and turns on the compressor almost immediately. A very obvious effect.
Modern refrigeration has a coefficient of performance (CoP) of 3-4, so the electricity it costs to bring your cans of beer down to the set temperature, is only 1/3rd or 1/4th as much as it would take to warm the cold cans up to room temperature with a microwave, hot plate/electric stove, etc., but it still costs energy and money.
