I never gave it a long test but it did seem to reach a point where it was going to stay running because the fan cooled the top just enough. But your are correct that at some point it can saturate and stop running. The stove always provided a huge temp difference so it didn't seem to be a problem but on my steam radiator the diff wasn't that great and eventually it would stop...
It is Radio Shack Catalog #: 273-258 The gear on the front fit the wood prop that I bought at a hobby shop. Any motor rated at 1.5 volts should work but the chips need a big difference in temp to put out enough voltage. I would like to find an even lower voltage motor or make a joule thief for the motor I have...
try to use a motor of an electric helicopter like Gyrocopter.
These motors have an very high rpm @ low voltage/amps.
Only disadvantage is the noise it produce.
I tested it on my TEG I'm building, but didn't used it because of the noise. I now use an old PC fan rated 12V but starts @ 4Volts and stops @ around 3Volts.
There are two 2" by 2" peltier potted chips sandwiched between a cast iron base and a aluminum heat sink. They are wired in parallel. I scavenged the base from an old asco contactor which happens to have a open hole on one side so one of the chips is exposed to the heat but I don't think that makes a diff. Since I have a gas stove the whole thing is sitting on a simmer plate to avoid burning anything.
Anyone have an idea, how to integrate this technology with the thermos technology?
I mean, how to make a longer heat source for the thermoelectric generator.

how long have you tested this unit running for?
If enough of the heat put in is not removed then eventually it will stop, no?

what wattage were you generating?

Hello fanplant , what type this little motor you use? Can I buy this unit? or motor? Thank you ezown at adelphia dot net

If one could run this fan off of the radiator
of a refrigerator then we have a little room
cooler without burning extra energy.

is that an exposed thermocouple?
