Terry, thanks for the link and your earlier threads circa 2005 but I had to go to PESN for the theory of operation
http://pesn.com/2005/06/26/9600116_Naudin_MAHG/ . I learned the Naudin device agrees with my premise of oscillating between H2 and H1 without using up the hydrogen but he seems to concentrate on a pulsed frequency to amplify the phenomena where I would have expected him to concentrate on increasing the surface area of the catalyst or even heating raw tungsten powder to circulate the hydrogen through. I believe that Mills and Chavra have a better handle on what is happening to the orbital states of hydrogen in a catalytic/Casimir environment. It is the hydrino/fractional hydrogen state that is absorbing energy from a permanent natural property of the catalyst while it is the covalent bond that is acting as the rectifier. When the fractional H2 tries to move to a different fractional value due to relative motion with the changing geometry of the cavity/catalyst the covalent bond opposes this motion reducing the energy needed to disassociate the molecule - When the opposition accumulates enough you can disassociate a molecule for less energy then the molecule releases when it reforms! This isn't in violation of COE but rather an exception to the rule that you can't rectify the normally chaotic energy responsible for random gas motion (HUP). The covalent bond effectively accumulates these energies because in a fractional state caused by local geometry it opposes further change in geometry. I think Naudin was close but should have concentrated more on increasing surface area of catalyst and heat sinking. I heard his name kicked around previously and never realized how close this particular device was to my own theory. Once more I appear to be a Johnny come lately. My concern for his implementation is a burn out of the tungsten catalyst. Like the Rayney Nickel of BLP I believe a runaway H2<>H1 oscillation will melt down any Casimir geometry and the plastic metal will simply grow whiskers to satisfy the force (shorting the paralell plates). If I had his rig I would fill it with tungsten powder and heat sinking veins and then bring up the temp to near disassociation while circulating a mix of hydrogen and helium that I could control to slowly elevate the amount of hydrogen. My premise is that at some point you could start backing off the current to the tungsten heater while increasing the hydrogen percentage and it would remain heated. Regards Fran
