I lived with my family for over 10 years on a 20acre mountain property in Southern Utah. No electric power other than the wind generator and a few solar panels. I had to figure out how to keep our food cold during the summer months. This idea came to me and I built it out of an old cupboard that was laying around. It work so well I could not believe it. The kids made jello during Aug., letting it sit overnight and wow. It was amazing how well that worked.
If you build one of these and just let it sit in the garage until the electricity goes out this little fridge will save all your refrigerator and freezer food. So simple to make. Take an old two or one door cupboard and cut the center out of the front doors and also the back. Drill holes in the side of about one inch or so and then cover it all over with chicken wire. The wire does not do much in keeping it cool, but keeps the cat and other rodents out of your food.
You will need a large gunny sack. I bought mine at the feed store, it came as a large sack and I cut it to fit. Next to the cupboard is a pan to hold water. As you see this is an old canning pan but we have used a soft plastic animal feed/water pan as well.
Place the gunny sack over the entire cupboard and then place the pan on top of the cupboard with the gunny sack ends placed in the pan. It will need a rock, brick or something to force the gunny sack down and now you pour water into the pan. The gunny sack will absorb the water and will run down the outside of the gunny sack along the outside of the cupboard. It will then begin to drip along the bottom. The breeze of the day will blow thru the walls of the gunny sack and cool the inside cupboard by about 20 degrees or more. If you place the fridge in the shady spot all day with plenty of breeze this fridge works great.
More great ideas from my book.
