Keeping it cool! I recently ran across this video on how to build Fridge that uses no power and helps preserve food for just a little longer. It is based on the idea of the swamp cooler. I could see how this could help keep food cool for a few extra hours in an SHTF situation. I’m going to build a couple of these to go in my preps. Keeping it cool! It is a simple idea and can easily be made with things available to anyone. Watch the video and give it a try and come back and let me know how you liked it. 🙂
