All circuits have all sorts of capacitive, inductive and resistive effects going on everywhere. That does not mean that any of those effects are significant, or even measurable. They will drown in the sea of tolerances that is a result of the components and the production process. Of course, maybe, just maybe, this circuit is made by hyperintelligent aliens that have figured out how to design a circuit using quantum entanglement or whatever, but back in the real world, Occams Razor tells us that the simpest solution is always the best one. We *know* people will scam other people to get their money. We *know* devices such as these have thus far been proven to be ineffective 100% of the time (when using double blind tests). No offence, but I am sometimes involved in hiring engineers, and I wouldn't hire you as an EE, if I knew the persistance with which you try to defend the Fuel Shark. Curiosity is good, but not when it is debilitating.
