"...charges the air molecules as they rush past in your air intake..."
 

My air clusters need breaking down, oh yes they do....

Some who sell fuel magnets also sell magnets for the air intake...though the polarity of the magnet is switched opposite.

Don't cross the streams. Very hazardous to run a fuel magnet and a polarized intake!

...is the salesman's name Dr. Peter Venkman, by any chance?

Hey, I just had a great idea! How about one of those for the nose? Breathe in air that has its clusters broken down and its negative ions energized, and you'll have more energy and be able to run & bike faster.

It sounds kind of like an ozone generator, creating o3 instead of o2 in your intake and that could work as o3 is less stable and it wants to bond with compounds, but from what I've read it could cause the fuel to start to brake down before it even got to the combustion chamber.

But would work great for a diesel.

Since matter can neither be created or destroyed (at least outside of the corral), where do all the extra electrons come from?

I try to keep an open mind & closed wallet about the theory behind types of things. Does anyone a whole lot smarter than me know if using negatively charged air would increase the "combustion effiecency & % burn rate" of the fuel?

I won't make any relative intelligence judgments, but there is a good reason this "idea" is being mocked.

...paraphrasing the phrase: "...stop and smell the roses..."

...here's the re-statement: "...stop and smell the Unicorn Meadow Muffins..."

I think the effect is intended to encourage flow, so unless you particularly like a long time on the throne then maybe not ?
