I've been advised by Geoff Lawton to use a 6' x 8" diameter black pipe to v
entilate and cool my home. Air from underneath a vine-covered pergola will
be pulled into the home from the poleward side of the house traveling to th
e equatorial facing side of the house where it will slip under curtains and
then travel up and out through the solar chimney.
I got the idea from a PDC he taught with Bill Mollison.
I am looking for as many details on this as I can find. Ideally, I'd like t
o hear from someone who has a working example. I'm going to implement this
next year on a newly constructed build.
