Notre collection

An intriguing film for anyone bedeviled by the high cost of home heating. A thermal engineer, Bill Loosely collects his warmth from the ground outside his house in Burlington, Ontario, and pumps it inside. The principle, using copper tubing and freon gas, is clearly explained with animated diagrams and by Loosely himself. It is so simple that you may wonder why you didn't think of it yourself.
