Clever Idea: The "Free Aire" system

Here's a clever little idea I read about. Imagine you live some place that's freezing in winter, with snow outside for a few months of the year. While it's cold outside, you heat your home. While your home is warm, you cool your fridge.

Now, if you could rig up in and out ducts to bring cold air into your fridge, you would need a small fan and some electronics, but would save electricity on the fridge's compressor.

You wouldn't break-even on a typical residential fridge, but apply this principle to a grocery store freezer aisle, and it becomes practical.
