pod, My son has a small fan that sits on top of his wood stove not sure how it works but it just runs from the heat generated by the stove. Really moves some heat around and his is rather small and I think only has 2 blades. I know his friend has one with more blades but I'm not sure if it is bigger.
Something like this but I don't think he paid more than $90.
