The eCool is probably the greatest addition that you could ever make to your garden. No, it isn't a healthy new super veggie but a cooler that stores beer in the earth and uses that to dole out cold beer year-round when you need it the most. (Of course, we suppose you could sub beer for soda pop, but where's the fun in that?)
The earth cooler is 113cm in height, 22 to 30 centimeters in diameter, and can hold 24 cans while staying installed the whole year. Just use a garden drill (or a shovel if you're a real man), and the rest is left to Mother Nature. There is no electricity needed, and it's frost-free during the winter. Drink up!
