Lifehacker explained how to use cold air from the environment to chill items in your refrigerator, effectively reducing power consumption. Very cool! (no pun intended).
It would seem obvious that you can pump ambient in to cool your refrigerator but difficulties arise in piping air and modifying the refrigerator body, among other issues. This article makes a simple suggestion. Take buckets and pails full of ice from outside and pack it inside an unplugged refrigerator. The refrigerator is already insulated enough to largely prevent melting. I mean a refrigerator and a cooler are pretty much the same thing, just a different scale.
So, save yourself some money and help clear the streets of slippery ice. Double commendation for being a good samaritan.
