Yep - but compared to the device I described earlier, that's the 'top of
the range' item. Bit expensive for the rest of us :-)
On the other hand, if you are building blocks of units ?

Why expensive...? Not being sbnotty, I don't see why they should be, so
I'm curious.

Referring to the deluxe version:
http://en.wikipedia.org/wiki/Image:Wind-Tower-and-Qanat-Cooling-1.jpg
Basement under the building, water channels under that. If they aren't
there already, digging holes like that will cost a bit, even without all
the WH&S issues. The version 'for the rest of us' eg a high-level vent
above the roof, with the opening pointing downwind - that's not too bad
in a lot of places. Of course, around here it might take a bit of work to
stop it coming off in a high wind (61 metres per second ultimate limit-
state design).
