The only wing that does not produce wing tip vortexes are Hump Back Wale flippers...
The research papers on the topic all talk about "reduced tip vortices", not "no tip vortices". Physics can not be fooled.
See company called Wale Power...
Funnily, the CEO of that company is called "Dr. Fish". He should be called "Dr. Mammal" instead, shouldn't he? Just kidding...
But really, these whales have developed a marvelous method for creating high lift at low speed with excellent efficiency and low drag. There will certainly be technical applications for that principle (e.g. fans and wind turbines). But aircraft need also be able to generate low lift at high speed for which this design is not suited well. So I doubt that we will see humpback inspired wings on normal aircraft.
