I didn't find anything really useful. Try calling applications engineers at
sensor manufacturers. They may send samples.

Have you found a 100W generator that fits on a wood stove?

I haven't found anything anywhere near that output range (using any heat

That was a part of what originally motivated me to explore development
of low-cost Stirlings. I haven't really continued the search other than
to remain alert for newly-developed products.

As you know, I have a strong personal preference for designs that don't
require a combustion heat source - and interest in that category appears
greatest in China, India, the Russian Federation, and Australia. If
you're wanting something with a less than 5kW output, I'd suggest
keeping an eye on on Chinese and Australian developments - the Chinese
because there may be available investment capital and the Australians
because they appear to be most motivated. Both the Indians and the
Russians have the intellectual resources to get the job done, but the
folks with the resources to underwrite R&D don't seem to be much interested.

I think the main reason Stirlings have found no automotive use is that
they don't change speeds readily. Zero to Sixty measured in minutes, not
seconds. They want to run at one power level.

They may work in hybrids, but I'm not so sure that the efficiency would
be better than a diesel, for a reasonably sized stirling.

It seems to me that stirlings own into their own using heat that
otherwise would be discarded. There is some oncoming use in concentrated

I want to buy a Stirling engine in the 1-2 hp range suitable for using
in a solar heat (~750F) context. Do you have, or can you find, a link to
a product with a price comparable to internal combustion engines in that
power range?
