No one likes warm beer, but the lengths you sometimes have to go to in order to keep it that way can be annoying; fridges are not everywhere and dragging a large ice-filled cooler around with you can be a nuisance. The Biersafe Beer Cooler keeps your suds cool by taking advantage of the fact that the ground tends to stay pretty cold, regardless of outside temperature. Granted, you’ll have to dig a rather large hole in which to place this device, which is a lot of work. But if you’re up to the task, you can store between 8 and 16 beers in a vertical rack that goes underground. It’s $70 or $120. We’re not sure just how cold is “underground cold”, but it’s an interesting product nonetheless.
