Minix wingtip vortices mitigation - How does it work?
The tiny mass of air that this device can affect will in no way have the claimed effect on induced drag. This wingtip vortex pseudoscience is just bullshit. What can be observed as a vortex behind the wing is actually the consequence of the vortex sheet rolling up due to downwash behind a lift-generating wing. But air flowing around the tip has almost nothing to do with it.

I would compare it to those magnetic rings you are supposed to put around your fuel line to save fuel. Snake oil, in other words. There is no way this thing can reduce the wing's vortex, all it will do is to create some more local turbulence.

All it needs is a slick salesperson, a few gullible people with too much money and greed, a big promise, and the scam takes its course. This can easily yield enough investment money to allow all scammers to drive a Ferrari for a year or more. Now they have a year to come up with the next big thing.
