Greetings Vortex,
I wasn t aware of Naudin s Patent Application:

Hi Ron,That one seems to have gone nowhere, but do not despair. Naudin has a new toy these days - called the "GeGene". http://jnaudin.free.fr/gegene/indexen.htm The name is an acronym but it could also be a French pun. Anyway, it is based on the peculiarities of the famous Tesla pancake coil when used as a transformer secondary, and combined with an induction cooktop, being used as the HF input power supply (~60 kHz). Here is one for less than $100. http://www.amazon.com/Burton-6200-1800-Watt-Induction-Cooktop/dp/B0037Z7HQK/ ref=sr_1_3?s=home-garden&ie=UTF8&qid=1358094166&sr=1-3&keywords=induction+co oktop OK first off - it is NOT overunity, at least it is not gainful when powering conventional loads ... and Naudin shows a simplified calorimeter with water boiling - which at 95% efficiency is still surprising in a way (you would expect about 80% with the losses) but it is clearly not OU. So why get excited? It's all about the load, and in the context of so-called "cold current". Some loads do not work for gain with the Tesla pancake, and some do (maybe). Now if you ask a number of EEs if there is such a thing as "cold current" - you may be surprised how many of them would agree that there is something "else" in some circuits, which is mysterious. Terry might correct me on this point but even if one includes the Aharonov-Bohm effect and other nearly-well-known mysteries, EE is still far from "complete" when it comes to things like the Tesla pancake. The main characteristic (assuming for the sake of argument that there is a mystery here) - is that this kind of current does not supply heat to some types of circuits in familiar ways. In fact the Tesla pancake coil stays cool at 1000 watts to the primary, but then again - it contains no iron and the primary is designed specifically to heat ferromagnetic materials. Catch-22 some of these cooktops will heat aluminum, but anyway... do not focus on the cooktop as being anything other than a cheap PS. Most observers would write this particular Naudin experiment off as meaningless ... or measurement error, despite the $10K DSO. Never mind that Naudin worked for EDF and has their support (the French grid power monopoly). Actually, I think there could be something valid to this one, despite the negativity on the forums, and I hope that the eventual surprise will be a better understanding of cold-current. Or at least a complete debunking - if nothing is there. Above in this post ... when I said "it's all about the load" that is not completely accurate - and what would be more precise to say is that cold-current is all about driving a special kind of bifilar ironless secondary inductor at high frequency through a special kind of load that will absorb more apparent power than the primary produces." Halogen lamps are one type but there are others, and curiously, incandescent lamps do not work. The $64 question is: "can one ever find a fit" - i.e. a valid commercial use for cold-current apparent gain, aside from a very expensive kind of lighting effect ? ... or else, did the great Tesla get it wrong with his unfulfilled claims for this kind of coil?
