Shade of Green: 100-year old pine tree
Items Needed: Stack of 2×4′s, 4 sheets of 2-inch foamular “pink board,” 4 sheets 1/2-inch CDX plywood, enough cedar tongue-in-groove paneling to cover the inside of your framed walls (exactly how much will depend on the size of your “fridge”), 2 small 24v computer fans, 1-3/4-inch hole saw, nails, general carpentry tools.
Why this Hack: Because you live in the north. Because it drives you nuts that you’re using electricity to chill your food when it’s 20 below outside. Because you’re committed.
Heart of the Hack: The idea is simple, though the execution is a bit more complicated. Basically, you’re building an insulated box that’s going to attach to the outside of your house (preferably in the kitchen area, and preferably to the exterior of an opening that already exists.
