In the broader field of energy anomalies, there is a class of largely anecdotal phenomena which involve, not just resonance but extreme "resonant persistence" - a kind of reverberation that seems to last forever.
The aim (of being this precise in verbalization) is to distinguish the time-frame for resonant decay in situations where the net energy may possibly surpass the input energy. Inherent in this understanding is the need to focus on the Maxwellian statistical distribution and the so-called "Boltzmann's tail" of that distribution. There is a Chapel in Scotland where scientifically recorded echos last fifteen seconds, and there are reports of Tibetan singing bowls, some made of a single gigantic crystal of quartz, with a reverberation peroiod of twice that long. They are called "singing" because the pitch seems to rise and fall rather than progress in a linear decay. At say 1000 Hz initially, decreasing to zero in 30 seconds, there would surely be 2,000 secondary "unpowered" sine waves following the initial "powered" one. It is somewhat surprising, given that kind of potential for OU, that an optimized thermodynamic balance has never been performed on objects like these. This is a preliminary post to what may become a more detailed essay, pending some promising experiments which are now underway by Ron Wormus, involving low duty arc discharges. All of these related ideas will share, as a starting point, the present analogy of the "tuning fork." If you have ever read the Keelynet stuff, you probably know it is one of Jerry Decker's favorite analogies... but it is not necessarily overworked as an accurate image, even for application to molecular gases, pulsed arc discharges, and cascading ions. The idea for finding OU based on resonant persistence - would be that if a certain periodic energy input is intense but infrequent, in a certain medium, then it may have a corresponding slow-resonant-decay, i.e. a very long Boltzmann's tail, so that if one can sum up the net resultant secondary energy, i.e. the "area under the curve," it would exceed the input energy. But this has never been demonstrated, in practice. For this process to violate the laws of thermodynamics, as currently understood, ZPE or the hydrino (or both) would need to be employed somehow. I have mentioned before the Wave Structure of Matter (WSM) website and the handy standing wave animation: http://www.spaceandmotion.com/summary-faq-wsm.htm This web site also has three interesting animations, http://www.kettering.edu/~drussell/forkanim.html "On the sound field radiated by a tuning fork" by Daniel A. Russell With two tuning forks, when one is resonated, the other will begin to resonate with the excited one, coming to near the same energy level, with rather surprising persistence - and in theory a large number of tuning forks arranged optimally, might show some kind of mutually resonant energy anomaly, but again, this has not been demonstrated on either the macro or micro level. In the case of a tiny rigid cavity or molecular sphere - which is small enough to intercept ZPE frequencies - that object could function like a tuning fork or an antenna, absorbing and re-emitting energy in order to establish local equilibrium. At this level, so-called inelastic collsions are indeed "lossless" but that is not enough for overunity - the bulk collision energy must be non-conservative and dependent on "external" energy (ZPE) or at least supra-chemical energy (hydrino). The wave spectrum of particular interest is the one where phonon-photon resonance is possible. That is to say where sound and RF share common frequencies. When a few ions are also present in a gas, the situation becomes a hybrid of the tuning fork and the capacitor. With capacitors, AC passes through them easily because of the alternating currents "cascading" through alternating charges, and the same is true of RF radiation; but with the added potential synergy that the "standing RF wave" may actually "force" a cascading-ion effect. IOW even after the external power has been removed, a persistent standing wave may actually continue to ionize a previously exicted but un-ionized molecule which is proximate in the ever-growing and collapsing wave reverberation. I am also using the term "RF" to encompass sound frequencies in the few-kilohertz range. A phonon-photon frequency overlap seems to be a requirement for this. The "analogists-amongst-us", may notice the connection between this hybrid modality of standing wave+charge... and the low duty cycle of the MAHG.... I will almost assure you that OU or not, Ron will be able to locate the point where a decreasing duty cycle has no further net benefit - and it will likely be less than Naudin's 5%, one suspects.
