Someone asked about a stove-top fan in this thread. In addition to the thermo-electric fan that is fairly popular with wood stove enthusiasts, there is a wood stove fan - the Heat Wave - that is based on 200 year old technology - the Stirling engine - which efficiently converts heat energy directly to mechanical. I got one in December of '05 and love it - although it is a bit on the pricy side - ~$170 - I got mine for $150 in December. It comes with a lifetime warranty. Contact info is below.

If you are interested in some of the research that is going on with this external combustion engine, just google Stirling engine and you'll be kept busy for a while. As an example, research done at Sandia Nat'l Lab in Albuquerque, NM with two electrical generating companies in California and a manufacturing company in Arizona is being applied to creating a 1 GW production facility in California. The basic unit is a Stirling engine with the hot end sitting at the focal point of a parabolic mirror about the size of an old satellite TV dish. The array will consist of a large number of these units. Another example is a unit planned by a New Zealand company that contains a Stirling engine in an appliance unit about the size of a kitchen dishwasher. It burns natural gas and supplies both electricity and heat for a complete household.

The contact info for the Heat Wave stove fan is:
