For anyone who might be interested.  Here is some research on the differences between the design of TEC and TEG pelters.

cBased on my research, there is a significant difference in efficiency and behavior between various peltier designs.

As far as I know these are essentially the same as the Peltier coolers. With the possible exception that the materials might be engineered for a different temperature regime.

The one you linked to can only handle 150°C max - I doubt most thermoelectric coolers have a lower Tmax than that (the first one I randomly looked up listed Max Operating Temp: 180°C).

I think that most of the TEC's sold are actually designed as CPU coolers, so they should be able to handle temperatures well above the boiling point of water.

Bear in mind, I am look for the TEG (thermoelectric generator) kind, not TEC kind often recovered for thermoelectric cooling.

I just need to borrow it.

Thanks,
