In studying aerodynamics of birds and how they use their wings, we see something that can help us in propulsion. We have noticed spiral, horizontal tornado type eddies above the wings, which increase a birds lift capacity, by way of suction. Tornadoes such air in and the birds wing along with it. This does not occur all the time in all birds wings, but we know it exists, in fact we have the same type of eddies on modern day aircraft.I propose we use lasers to temporarily create mini tornadoes to.
