Its an invention to save energy by not using your clothes dryer so much. You stick the Air Flow Dryer into your central heating duct (100 million homes in north america have central forced air heating). You can dry all of your towels and wet clothes, use your shower towels for 7-10 days, then wash them. If everyone uses their heating more efficiently, it saves your money and energy. Its made of recyclable plastic and will pay for itself in a few months.
