This is a very interesting concept, and one that hits close to home for me. In my senior year in engineering college, I led a design team that created a device practically identical to this and attached it to a lawn mower with great success while running on several different fuels. No plasma was created, and I do believe that word usage was strictly just for the sales pitch of Paul Pantone. Thermodynamics are the true driving forces behind this concept, and we've got a rather extensive report showing the fundmentals of how this works.
I've actually got a few videos posted showing our device running if anyone has interest in seeing them.
Cool. Yeah, I'd be interested in seeing. Did you measure efficiency and pollution results? ...regarding "word usage", I personally find beliefs to be counterproductive at best, but to each their own. ;)
Here's a couple videos of various fuels running in the gas mower, and as you see, they performed fantastic. I also have some more that would be with my report files that I will try to locate.
It might take me some time to locate the reports since it has been a few years since I did this, but I will certainly try to locate it today and post back. But yes, we do have results in regards to efficiencies on various fuel types along with emmision results, which compare to the unmodified lawnmower as the data reference.
