Nothing is worse than a lukewarm beer on a hot summers day. You could install an outdoor fridge but this requires electricity which will cost you money and anger some environmentalists. Some creative designers have solved your beer cooling dilemma with the eCool. The eCool uses the constant cooler temperature of the earth to keep your beer desirably cool. 

You basically dig a hole, drop in the eCool and have 24 cans of drinkable beer. the creators also claim that those living in cooler countries (aka Canada), can enjoy this year round because the eCool will prevent the beers from freezing. 

You can order one now from the creators for a mere $US349 (link)
