The roof top wind generator is design to mount on the ridge of a roof to capture the wind energy without any obtrusive towers or unpleasant looking structures or equipment. The basic design is a multi-fin turbine, built into a roof cap design. When the wind hits the flat surface of the pitched roof it moves up the roof to the peak much like the wind currents over a airplane wing. When this happens the wind speed is increased to nearly double the velocity at the peak. The roof top wind generator captures that increased wind velocity as it moves over the peak to increases the effectiveness of the wind generator.
