For years, scientists have been warning of global beer warming, but, until now, no one has had the guts to stand up to Big Ice.
Thanks to the four green-minded Danes behind the eCool, there's now a gadget that will naturally cool beer without ice or electricity. How it works: You dig a 3ft hole in the ground using a garden drill or a shovel or a pet gopher, then install the cooler. Earth's surprisingly chilly crust insulates up to 24 beers and keeps them at a refreshing temperature year-round. When you're feeling thirsty, a simple hand crank mechanism disperses a frosty beverage.
The cooler comes with a hefty price tag ($349!), and is not exactly portable, but theoretically this could pay for itself over time by lowering electricity bills and keeping the melting polar icecaps from ruining everyone's parties.
