The wind Catcher's of the middle east scoop the air in a move it 
thru the house. The often have multiple shafts to allow facing 
different directions so the wind goes down one set of shafts (facing 
the wind) and down to the house then back up and out the shafts that 
are facing opposite the wind.  sometimes the path into the house 
would cross over an undergound water reservior.  The wind catcher 
then works as an evaporative cooler when used with water.

I have not thought of the condensations in the pipes...mmmmm
Better slope them a bit out.
