Jacques - Basic principles: In addition to any wedge effect from the lower surface, it's the air over the wing. It gets thrown downward. The cute part is in why it sticks to the wing surface well enough to follow the downward curve. The answer is in the Van der Waals forces. Some of those might be overunity, but I don't think wings, at least the ones we build, use them that way. Maybe bugs do, especially small ones operating at Reynolds numbers dominated by viscosity.

Hi all I have written a document that demonstrates how to apply the laws of motion to create an unlimited build-up of momentum. The phenomenon I describe in the document was used very successfully in the past (although people did not realize it was over-unity) with the Pelton wheel. We all know that the conservation of momentum tries to prove that over-unity cannot exist by demonstrating how this law holds during a single elastic collision. Over-unity, however, is demonstrated by utilising the !!absolute!! result of a series of successive elastic collisions in order to reclaim greater impulse from lesser impulse. The laws and equations used in the document are no more than those taught in basic momentum physics, and it shouldn't take more than 5 minutes to grasp the principle. This is no hoax, so just keep an open mind... http://blogspace.mweb.co.za/site/alias__javanwyk2012/0/Default.aspx Jacques
