I wanted to start my own thread with this, but a few weeks ago I bought a 6W TEG module that produces 4.1v@1.4A . I attached it to the biggest heatsink I have and got no where near that output. I was lucky if I got 1V at 20mA. I was using a candle as a heatsource. My next idea was to use some high temp insulation from mcmastercarr. That didnt really improve my output much. According to the data sheet, their test conditions are Thot = 300C Tcold = 30C .

But heres my idea. Recently I bought a milling machine and Im thinking about small watercooling system for it. Now in order for water to flow a small pump needs to be on, but in order for the pump to be on there needs to be enough output. I was thinking of using a small battery to get things going and then once the TEG is producing enough, it will charge the battery and also run the Pump. Any extra energy would be available at after that point. Basically the battery is there to get things started.
Anyone have any suggestions or ideas to add? I found a small DC pump on ebay (3 to 12V). The rest (including a radiator) I can make. This is also more of a curious thing (like stirling engines) just to see how far I could go.
