I saw an interesting show on the History Channel a while back.
It turns out that several hundred years ago in India, architects had designed palaces with pools built in such a way that (warm) breezes would circulate around the pool and blow cooled moist air through vents into the chambers that the king lived in.
Is anyone more familiar with this ? If I had a house, I would try something similar.
I wonder if placing a small water trough in front of my windows would have the same effect ? Probably not. It would most likely just bring in humidity ... or attract mosquitoes !
