DIY Wood Stove Fan for under $50 - All

They sit on top of a log burner and suck out heat from it and the pielter device generates electricity and runs the fan, which blows the hot air off the heatsinks.

That's not a real great one. I'd go for a larger bottom heatsink, fins up, and a vertical downwards blowing CPU heatsink.
The top heatsink has to be colder than the bottom one to generate power. (Pielter devise)

I like it. I think that using a brass or copper propeller would enhance the steampunk look.

Where do you find peltier devices in scrap?

They use Pelter's in electric chilly bins (Coolers in America?)
Often the plastic casings broken, or broken hinges.
I'm not really a fan of them, they use up too much power and flatten battery's and can only stop something from heating up a bit, like they won't cool or freeze anything, there might be good ones out there, but...

Some water chiller units for home or office, They run on mains power and have a good power supply, if it still works, its probably worth more to sell like that as 'project parts' on eBay. People use them for weird things. Cooling chips in computers etc.
If its power supply's not working, Pelter's have no real reason to stop working, the device will still be working. Easy to check though.

My mother-in law got me the Ecofan version of this for my woodstove. I use it more for a thermostat - when the fan starts to spin I know that the stove is getting good and hot. I does
not move too much air around though. I gave a friend of mine a few of those heat sinks to build the fans but I have not seen them yet. Maybe this fall he'll finish them.
