The way I subverted my friends from believing that the "tornado" was worth anything more than it's weight in scrap:

"Have you ever seen a real tornado, even on TV?"
"Yes"
"Have you ever seen or heard of a tornado turning into a right angle that has a radius of less than 3 inches while maintaining no conical shape and having a velocity over 200 CFM constantly?"
"No..."
"So why in god's name would you think that something like this, that is advertised to "spin the air" in your intake, work?"


Later, we proved it on several people's cars by imitating the product with pepsi can alternatives... of course, there were several arguments afterward (similar to the HHO debates right now) about how each one had a different angle on the fins, or used a different number of diffusers, etc.

But, the vast majority of people I knew, or that knew me, or listened to anything I said at the time, never bought into the scam. They gradually woke up to the fact that the best that "thing" was doing was slowing down the intake because of it's mass blocking the intake flow.. then the "spinning" vortex of air it claimed to create would actually create a vacuum in the center that would further destroy airflow... had it worked to begin with.

Thanks to my science teacher showing us what a real vortex generator does, else I'd have never had the evidence to prove that stupid thing incorrect... and there are still people in the area where I used to live that use them, and SWEAR BY THEM, saying that they, on top of a weekly regimen of about $15 worth of additives, give them another 4 MPG.


I can honestly say I've never heard the "sonic transducer" theory... have any links? That might be interesting reading.
