[edit] Windcatcher

I appreciate your attempt to come up with a themodynaically sound explanation of the Windcatcher. You are right: we need an expert to clear this up. In view of the fact that experts seem to be scarce I did some surfing, and I found an article on Conservation of Badgirs and Qanats in Yazd, Central Iranby Dr Reza Abouei. In it he offers the following explanation of the way the Windcatcher works: The badgir, literally the ‘wind-catcher’ is a high structure built above the roof of residential buildings that catch the passing fresh air and channel it down to the ground floors and basements. The weathering shaft, ventilation shaft and wind tower are other names which are also used for the badgir. In the badgir, the hot air is captured at the top of the structure and passed through a simple canal, delivering the cooler air at the bottom of the canal, where there is a small water pool in the basement. So, this actually suggests that there is a downdraft in the windcatcher rather than an updraft. Of course, downdraft is a sort against the nature of things: updraft of hot air is thermodynamically more logical, as you suggest in your contribution. Anyway, I thought it would be interesting to hear your opinion about about this alternative explanation. JdH 17:24, 12 December 2006 (UTC)

[edit] Environnement2100

Hi, thanks for taking out that section in Export land model. I would have done it a long time ago, but I didn't want to be seen as starting an edit war with that editor (who had previously started taking everything I did personally). He hasn't edited Wikipedia in a couple of months, but I still wanted to err on the side of caution. NJGW (talk) 04:42, 13 March 2008 (UTC)
