Paul, snipping doesn't count if you then include all of the preceding
thread appended at the bottom of your post, within two messages you
have increase my original post of 38 lines to 144 lines. So by all
means snip out a bit that's relevant but then please delete the
original bits that are not pertinent.

As most people know I am a heat engine enthusiast but I hope I realise
their limitations. IMO Stirlings can do useful work but their
attributes are potentially long life, quiet running and able to use an
external heat source. They also need to be well made. So they have
found niches in submarines for quietness, toys because of their
ability to "work" with very low temperature differentials and now in
home heating systems for co generation of electricity because the heat
they reject is still good enough for heating even though they only
generate about 10% of the total as electricity.

Well of all the technologies available for providing the fan power by
the heat of the stove I had plumped for semiconductor TEGs because
they seemed to provide power for mass produced fans, both steam
(ejector and turbine) and Stirling looked too complicated in
comparison and the parasitic load of the steam looked bad.

I was disappointed to see no comment on the Phillips running under its
own TEG power.
