Tom, This is encouraging. The Hi-Z thermopiles have a basic output voltage of 3.3V; I thought at least two would have to be stacked to run a typical 12V fan and I've only found one source of <12V fans. (In my experience a 12V brushless DC fan will run at 6V, but not much less.) Do you know the fan make/model? I think there's general agreement that a few watts for a fan should be lots. I don't know where this 40W figure came from. -=s On 21 Nov 2002 at 16:07, Tom Reed wrote: > Dear Peter and All: > > Our WoodGas Cookstove (Campstove in the U.S.) uses a 1.5 V battery > which lasts 3 hours on high and 6 on low, small fan and consumes 0.75 > W.
