I was sure that I had seen such a device before.

After consulting my undergrad text on the subject I found a picture of
such a device which was (maybe still) manufactured by 3M.  It produced
200mW at 9V.  It could run for 24 hrs on a tank of fuel (kerosene) that looks
like the one on a standard coleman lattern.  It goes on to say that the
thermocouples(I count 6) were hermentically sealed.  Therefore expensive?

It is described in:

B.Swanson and E. Somers, "Optimization of a Conventional-Fuel-Fired
Thermoelectric Generator," Journal of Heat Transfer, 81(1959), pp. 245-248.

A. Bayne Neild, "Portable Thermoelectric Generators," Paper No 645A,
Transactions of the SAE(1963).

The text in which I found the info was:

S. Angrist, "Direct Energy Conversion," 3rd edition, Allyn and Bacon Inc.,
Boston(1976), pp. 176.
