I haven't seen any discussion on steam powered fans. Have we been
there already?
Mike
I believe so, yes. Though that could even be integral, with a water
jacket, but how much fuel would be left by the time you'd boiled
enough water to power the fan, and how much smoke would there be in
the meantime? Hm. Thinks.
Thanks!

You didn't check the link. The woodstove is operating when it's not
cold outside the building because these are not heating stoves,
they're small cookstoves for use in tropical countries. There is no
"building envelope", and Peltier units are not cheap, nor readily
available in 3rd World rural communities, nor something that can be
made locally, so as far as Appropriate Technology is concerned
they're not a good solution even if they worked for this application.
