Stooopid is not pretty.
Microfabrication of dense Peltier junctions.

The problem with really compact thermopiles is the thermal separation of the
hot and cold junctions.

Of course nowadays the whole thing is not much more than an interesting
curiosity, but the interest in this particular arrangement is its potential
for low tech fabrication, difficult when a whole lot of fiddly junctions
have to be assembled.

The device could be made like chainwire fencing with dipped hard soldered
junctions. Now mould the thing through the wall of a ceramic chimney, water
jacket outside. The experts out there can tell us what materials to use...

Some interesting old stuff about thermopiles:

Just think, you could run your laptop on gas....
