"This Old House" showed a gas power "AC" unit from the late 1700s early
1800s a while back in Savannah (I think). It was basically a cupola with a ring of flame from gas that when running would create an updraft and pull air throughout the entire house. Quite a bit of air as I recall. One of those "outside the box" designs where you use fire in the summer to cool a building. :)
