Some call it Brown's Gas, some call it HHO, and still other(most of the world) call it a stochiometric ratio of H2 and O2. We are putting the water under electrolysis.
If you take a detailed look at where these myths are coming from, it's usually someone trying to sell their "revolutionary" product on ebay, or some other site. The bottom line is, you should strive to produce the most amount of HHO, with the least amount of power. In other words, get the highest efficiency. Plate spacing, electrolyte concentration, plate resistance, and PWM efficiency are the main areas of concern in doing so.
I wouldn't poo poo this "rumor", just the PWM that are sold as if they do this. I'm not saying that i know this one way or another, but I would expect that with a highly tunable PWM and a cell made to a .0001" tolerances you might find a frequency which is more efficient, it might be many ghz, and such a PWM may have inefficiencies that were greater than using a more standard frequency one. This is a subject that needs some experimenting with, but we're not there yet, and ebayers are behind us for the most part.
I=V/R so R=V/I and V=I*R
P=V*I
(I=Amps, V=volts, P= power in watts, R=resistance in ohms)
