Sorry if you feel attacked, not my intention to attack you personally but to attack ignorance. Ignorance can be cured and most of us appreciate being disabused of wrong thinking. It isn't that I don't know the difference between their and there but my fingers can easily outrun my brain and the spell checker doesn't do grammar checking.
USAF huh? What was your MOS? I was also USAF and went to a 8 month electronics course where we learned lots of stuff, some of which was useful. Having made my living in various technical areas I have a more accepting attitude regarding being shown something new I hadn't been aware of previously. I too rail against "snake oil" like pills to put in your gas tank to let you use water instead of gasoline. There is lots of junk with no valid science behind it for sale. However when honest folks are reporting success with a circuit that you haven't tried it is disrespectful to indict them as believing in philosopher's stone etc. As it has been pointed out by others there are lots of commercial applications of this equipment. You come across like the fictitious aeronautical engineer who proclaimed the bumblebee could not sustain flight as the wings were too small, too inefficient and powered by muscles incapable of sustaining flight and the fuel consumption would be too great for the on-board energy reserves thus the bee could not maintain flight. Since the bee does maintain flight it is safe to assume that at least one of the assumptions was wrong.
Similarly there is good science behind the desulfation of batteries to extend their life. This is true even though you were ignorant of it.
When you can't fault the science and cant find flaw in the logic resorting to picking on a trivial typo in an unwarranted ad hominem attack is not a way to increase your esteem in the eyes of your fellow TBN'ers.
I apologize again if I have made you uncomfortable. Not to worry, this will all blow over soon, a tempest in a teapot as it were.
Oh by the way, I have at times made my living as an electronic circuit designer in diverse endeavors ranging from medical electronic equipment to man packed battery operated welders. I have seen the impossible done too many times to be eager to count coup on someone claiming to be doing something just because I hadn't seen it before or studied it in the USAF.
By the way... thanks for your service to our nation.
