Deep-Freezer Root-Cellar

I've seen a few people discuss this idea around the web, so I went surfing around and found a web-page that shows the concept well.

It's a great idea. I mean, how much does it cost to find an old freezer that no longer works, dig a hole, and bury it? On their web page, they also say it does wonders for keeping out rodents.

Quick Tip: The Window-Well Miniature Root-Cellar

Basement window wells can make quick, cheap and easy root-cellars. Try to choose window wells on the north side of your house to prevent excessive temperature deviations caused by the sun. Cut a piece of plywood to cover the opening and attach insulation to it, as well as insulating the inside of the well. If necessary, open the basement window to maintain a temperature between 32 and 40 degrees Fahrenheit.
