# Minix wingtip vortices mitigation - How does it work?

I stumbled upon this article: Minix wing tip device promises 6% gain in fuel efficiency for airliners.

Such an economy is appealing and I must confess the design is "sexy".

Could someone expand a little bit?

• those grooves should be twisted the other way to minimize the vortex, as is it seems like it would aid in vortex creation – ratchet freak Jun 29 '14 at 14:20
• It seems to be an aerodynamic device. I would think it works by generating angular momentum that acts opposite to the angular momentum of the vortices – user7241 Apr 10 '15 at 13:59
