Heat Wave Wood Stove Fan
Self-powered fan

When you want to move the hot air from the wood stove around the house, what better way than to use a Stirling Engine powered by the heat from the stove? This little engine really moves, and moves 300 cubic feet of air per minute. It is quite robust, made of heavy gauge welded steel, aluminum and brass, and stands up to abuse, although it doesn't get much abuse sitting on top of the wood stove.
We don't let our wood stove get above about 500 degrees Fahrenheit, for safety reasons, but this little gadget can easily take twice that. We have played with it on a gas range that gets much hotter than the wood stove, and besides the steel getting a nice blue color, no damage was incurred. And since it moves the air around near the stove, it helps to keep the stove cooler and the room warmer at the same time.
It works well, does a useful job, and is a great conversation piece. And it uses no energy except the heat from the wood stove.
You can buy Peltier-junction thermoelectric generators with a motor and fan that are made for the same purpose (moving the hot air from the stove into the room), but ours lasted only about a year before the Peltier junction became intermittent, and the fan stopped working. The Stirling engine in the Heat Wave has had no such problems -- it is built like a tank.
