something is not quite right here, does this make sense at all to anybody? even if for some reason air on the top is hotter than the air next to the hot ground, after a short while the draft itself, makes a local equilibrium, and it is hard to believe you can over come this by spraying water and cooling the bottom of the tower, and all of this just by testing on a 4 feet tall model in Maryland?!
