Root Cellar Cold Storage

Another part of long term campsites that many have not considered are how to store food without electricity especially in the event of an EMP. Below are several different designs for root cellars made from barrels. Im trying to look at designs that anyone can make without a lot of cost that can also be easily transportable. i like a combination of the below designs.

I have made one of these out of an old fridge to experiment with above ground and was impressed with the results using a solar chimney. The theory is by using the sun to heat the upper stack, the air inside will rise drawing cold air in the lower tube. I would also like to use holes in the bottom of the barrel to remove any moisture.

Ethylene Gas

When Fruits such as apples and pears ripen, they give off ethylene gas. Ethylene gas decreases the storage life of some produce. Ethylene gas can cause sprouting, decay, mold, yellowing, shrinking, toughness, softness, bitterness and other damage.

To combat spoilage from ethylene gas, segregate fruits and veggies that produce excess ethylene gas from those that are easily damaged from ethylene gas. This is a good idea for your refrigerator produce bins, too.

Fruits and Vegetables that may create excess ethylene gas include:

Apples, apricots, avocados, ripening bananas, blueberries, cantaloupe, citrus fruit (not grapefruit), cranberries, figs, guavas, grapes, green onions, honeydew, ripe kiwi fruit, mangoes, melons, mushrooms, nectarines, okra, papayas, passion fruit, peaches, pears, peppers, persimmons, pineapple, plantains, plums, prunes, quinces, tomatoes and watermelon.
