While I realize no self-respecting scientist will pay any attention to this, I'll post it anyway. Physical sound is never included in the Physics equations of LENR. Yet the late Ken Shoulders, whose paper is attached repeatedly said, (and it's in the abstract) that the shattering the the deuterium-loaded crystalline structure metal, with its corners filled in by the H from the deuterium is able to hit a resonant frequency and crack/fracture (think soprano shattering a wine glass with a resonant frequency from the physical sound of high-C.)
As Ken told me personally, the electrified metal, when it fractures, emits a spark, which is, in essence, composed of multiple toroidal-shapped bundles of of extremely short-lived existence and are extremely energetic electron bundles that have been compressed beyond the Coulomb Barrier by Casimir (van der waals) forces. He called then EVOs (Exotic Vacuum Objects). Hal Puthoff called them condensed charge clusters.
Shoulders claims that these are responsible for the clumps of transmuted materials, e.g. nickel, tin, etc. found on AND below the surface of the metal that has cracked, BECAUSE they affect (real: alter) the atomic structure of neighboring atoms. However, they are so short-lived, their influence is limited to localized domains of atoms. Thus, the "clumps" of transmuted marterials. Actually, I never heard him mention if the electrons compressed beyond the Coulomb Barrier in these EVOs ever reverse direction and are passed back through the Coulomb Barrier, only to become plain old electrons again, except now they are part of the transmuted element.
In any event, @ ICCF-10 Peter Haglestein gave Dr. Fulvio Frisone a noted Italian scientist and quadriplegic, he opportunity to present his poster paper. One of Dr. Frisone's grad students read it for him. The conclusion of the paper was very clear - no cracks, no cold fusion. I later asked Dr. Frisone if he knew of Ken shoulders' work. No, he did not.
Let's assume for a moment that Dr. Frisone's conclusion is corroborated by Ken Shoulders' contention that it is the EVOs from the spark created by a harmonic resonance within the crystalline metallic structure that cause the tiny crack, and associated transmutation(s.) - AND the excess heat of cold fusion. If you read Ken's paper "Charge Clusters in Action", you will find that a simple spark that emits EVOs (condensed charge clusters) can blow a hole (melt straight through) aluminum. Ken claims that would normally require a thermal gradient of 26,000C - table top fusion.
OK, if you haven't written this off as every cold fusioneer I've ever spoken to has ( 2 scinetist from Los Alamos were aware of these "fracto-emissions" but didn't have the math to explain them. Ken later added the math in his revised version of "Energy Conversion From the Exotic Vacuum", in the attached document. But, at that point, Ken Shoulders had already been written off by the cold fusion community as simply wrong, and was consequently ignored,) may I suggest an approach that as far as I know, has not even been considered, nor would be considered by any self-respecting scientist in the field who already knows, "it can't be, therefore, it isn't". That approach would be to simply determine the resonant frequency of the metal being loaded and add an additional component to the equation / experiment: physical sound (which travels better in water than air, so some underwater sound generator that can be adjusted to generate the resonant harmonic frequency of that metal can be "broadcast" throughout the medium, whatever it might be, that causes (read: assists) the metal to fracture) and see what happens. Will it shatter like the wine glasss and emits EVOs that are the real source of the excess heat as they break the binding energy of the neighboring atoms and transmute them into other elements with electrons that have returned through the Coulomb barrier to become real electrons, except now as part of the newly created transmuted elements?
I know. i know. This is all uneducated rubbish, not even worth reading. But, I think it was Einstein who said that doing the same thing over and over while expecting different results is the definition of insanity. It's been about 25 years of insanity in the cold fusion community. Maybe one of you might try to approach it a like Apple - different.
