How to make a stupid-simple open-air refrigerator

Why pay for what Mother Nature is willing to give you for free? If I’m inside my house in the spring or fall and there’s a nice, cool breeze outside, do I keep my windows closed and run the air conditioner? Of course not. I turn the air conditioner off, open the windows and let Mother Nature cool off my home. And you know what? She never sends me a bill.

Well, the same concept holds true for keeping some of your food chilled when it’s cold outside, which in many parts of the country is roughly one-half of the year (mid-October to mid-April). I’ve learned that you can build an airtight box insulated all around with pinkboard that’s attached to the outside of your house (preferably in the kitchen area to the exterior of an opening that already exists) that will be an effective way to keep food safely chilled in a grid-collapse situation. And at the very least, you can save some money on your power bill in the meantime.

Take a look at this article “Grid Down DIY – Ambient Air Refrigerator.”

Does the idea of keeping some of your food chilled without paying for power intrigue you enough to want to give this a shot in your home? Do you have any thoughts regarding how this ambient air refrigerator could be improved from the way it was described in the article? Let me hear from you in the comments.
