That looks identical to the ones they sell at Lehman's, but with nicer prices. Theirs run $120 - $148. Looks like a great deal.

There are also Stirling engine powered woodstove fans available commercially too, which I believe may be a bit more powerful than the thermocouple models. (at significantly higher prices) Google "stirling woodstove fan"
