Vortex Generators have been used on airplanes for decades now, its amazing what a little "fin" can do. At least on an airplane they increase fuel efficiency, create more lift, less drag, lower stall speeds, reduce takeoff distance, increase rate of climb, increase max takeoff weight. and the ones on the plane I fly the help reduce the accumulation of ice over the wing.
Lately Ive been seeing people add these to their cars and trucks, and while the idea is there, there has to be a bit of engineering on the proper placement of the generators so i wonder if they help or hurt aerodynamics when they are placed in random places.
