Now let us suppose that we have a free source of rotating-shaft power
in location A.
And let it be further posited that we need fresh-air ventilation at
location B.
At which distance does it stop being most efficient, to setup a fan
at
location A, and just run a plenum?

Free power? You have a waterwheel set up? Too many factors.
Cost of electric, cost of materials, how long you plan to be
there. Can't see it from here.

Naah, we've got the complete, and restored math. But, now,
Presby women can do algebra and calc, too. So, you know
there's somthing going on.
