Trees are also aerodynamic design structures to permit a large frontal area necessary to the functioning of the trees.
Trees tend to avoid destruction by the wind by rounding their lower frontal branches to the approaching air and by coning their upper branches to point in the direction of the leeward and upward draft, thus reducing drag to a vital degree.
In the same way it became evident that a large ventilator could be designed to rotate upon the top of the house in such a manner as to focus the low pressure-- caused by the air passage about the building-- at a point about 45 degrees leeward and upward from the center of the house. The ventilator was developed… until a successful design was arrived at which reduces drag to a minimum and prevents oscillation of the ventilator, while at the same time putting the focused low pressure to work in pulling the draft out of the building through a duct system that induces the draft to create an air conditioning circuit, as well as to remove dust from sweeping traps in the floor and odors from the kitchen and bathroom.
Certainly air conditioning is a requirement of housing which
