If you own wood burning stove and you would like to get MORE HEAT throughout your room but you DO NOT want to spend more money on electricity - all you have to do is get one of these amazing heat powered stove flue fans, and you will be warm for FREE! - this manually operated fan generates its own energy and is powered by heat alone - no batteries or electricity required.
How does it works without batteries:
It seems impossible, but this fan runs without batteries or electricity. As the base of the fan heats up, the metal in the bottom of the unit warms along with a heat sensitive spring. Meanwhile, the temperature of the different metals in the unit's top surface is kept down by the fans cooling fins. When the heat sensitive spring reaches a sufficient temperature it tilts the unit forward, bringing the two layers of metal together. This creates the electrical pulse that turns the blade on the fan. The greater the differential in temperature of the metals, the greater the electrical output, meaning that your fan turns faster the more the stove (and therefore the base of the fan) heats up.
