"Easy Root Cellars & Low-Tech Fridges
Root cellars are an ancient method of preserving fruits and vegetables like apples, onions and potatoes throughout the year. The stable temperature of the earth below the frost line creates enough natural ‘refrigeration’ to keep these items fresh. While traditional root cellars were often walk-ins, most of us don’t need that much space for one household. You can create a root cellar using recycled and reclaimed materials. Bury a non-working chest freezer or even a trash can in the ground.
Want to go without a refrigerator altogether? There’s a cool low-tech way to keep items cool on the countertop. Pot-in-pot refrigerators, known as zeer pots, can keep veggies fresh for up to 20 days, even in hot climates. The contents are kept cool by a layer of damp sand between two terra-cotta pots; as the water in the sand evaporates, it helps cool the inner pot."
