I did a Google search for "Minix wing tip"
Curious on what others here think/feel/know......
These sorts of things are what happens when intuition is applied inaptly, kind
of like those early schemes proposing ways for making balloons dirigible, i.e.
steerable...you know, oars and sails and the like. How does this magical
"unwinding" device go about capturing the entire pressure differential between
bottom & top of the wing so's to prevent vorticity developing? Methinks at the
very least a considerably larger bell-mouth is in order to have potential for
ANY detectable vortical disruption. :-)
Quite Possibly/Presumably In the "Know Dep't." (Copied from comments)
"I tested this device for my university thesis and it done nothing at all but
to increase drag due to the extra skin friction drag caused by a greater
surface area. The vortices do not reduce because the design considers the
physics on too primitive and intuitive a level."

Excellent discussion of "Common Misconceptions in Aerodyanmics" Worth the time to listen to the whole thing.
