Wow thank you very much for that info. My lab partner had been talking about something to do with laminar flow and reducing drag and air pockets that build up on the tops of the wings.
Actually I was reading that you want the turbulence on the tops of the wings... Right?

So I was just reading about ground effect and how it works. So if it works from wing tip vortex reduction and creating a cushion of air, is this why biplanes were developed? What if you had a second wing that was strictly for creating a false ground effect? I believe it could be made lighter and still create the ground effect.
