    Say IH is absolutely right- then why on the Earth should it attack so wildly the opponents.

    IH are attacking and have attacked no one. They've been admirably discreet and vague about Rossi over a period of years and continuing into the lawsuit that was started against them with their own money. This discretion on their part has been turned around into fault for their not making a fuss in public earlier. The "attacks" you must be referring to would perhaps be Dewey Weaver's efforts to set the record straight on behalf of IH, his friends and business partners, when he's clarified, and they've clarified, that only IH speak for IH.

    I also find it funny Rossi is still claiming the "Swedish Royal Academy of Sciences" performed Lugano:

    Reminds me of the earlier work accredited to the University of Bologna. Or, in Mills's case, to work done at the Harvard Smithsonian Center for Astrophysics (key word: "at").

    I just said, that reference to lack of evidence cannot serve as the evidence of the opposite - but evidence of pluralistic ignorance. For example ENEA lab achieved the reliability 70% of cold fusion at their palladium samples in 2009 - by now it will be probably even higher.

    You've conflated evidence for LENR with evidence for a lab rat. We have plenty of evidence for LENR. What we don't have is evidence that there is a suitable lab rat experiment. The evidence for LENR, as we know, is patchy and hard to reproduce, but nonetheless there's a lot of it. The evidence for a lab rat cannot be patchy and hard to reproduce by definition. If such was the case, we wouldn't have a lab rat experiment, and we don't.

    If Szpak had a suitable lab rat experiment in the IR thermography you point to, we would only know after the fact when other independent labs succeeded in reproducing it. It is not Szpak's fault if this is something that would be straightforward to do and other groups have simply not taken the initiative. But neither is that experiment a verified lab rat experiment yet, by widespread understanding of workers in the field, until other groups have seen some success in replicating it and start to use it to characterize LENR. For we're talking about a lab rat experiment and not about LENR in general.

    The general understanding of motivation for LENR dismissal with scientists is generally not very deep even here, at the LENR forum.

    We're talking about a lab rat experiment and not LENR.

    Nanortech is using exactly the same term at its web page. This page also says, that "Nanortech anticipates it will be setting up a pre-order list by Fall 2016. Unfortunately, there is not at present the capacity to make these components generally available in the short term".

    For the purpose of whether an experimental protocol or apparatus is a "lab rat," as the term is used by workers in the field, it does not matter that someone claims they have a lab rat, as in the case of the NANOR. What matters is that independent laboratories have had success in using it to tease out details about the LENR mechanism. Which hasn't happened yet with any device.

    Is your intention to reach mutual understanding on this topic, or is it simply to reply with retorts to every valid (and in this case, obvious) point that is made?

    On my opinion you are clearly trying to diffuse false information in order to influence the trial.

    I presume that this is against law.

    Because this forum is moderated I presume that eventually also the moderators of the forum could be responsible.

    Paradigmnoia is not the first person I would guess would be here in order to diffuse false information. He is one of the last. Others, by contrast, do make me wonder as to their motivations. Thankfully logical argument wins, when people are able to engage in it, and motivations do not matter so much.

    Such an objection smells with pluralistic ignorance, which is red herring behind one century long dismissal of cold fusion as such with mainstream physics.

    I asked you for the names of groups that are using NANOR's kit to gradually characterize LENR. This is a specific question: there are such groups, or there are no such groups yet. In the first case, we have a bona fide lab rat. In the second case we do not yet have a bona fide lab rate, despite Swartz's claim. This is entirely independent of whether the NANOR kit can eventually be shown to be such a lab rat.

    The proponents of this physics claim, that cold fusion doesn't exist, because nobody did succeed with it. ...?!? Well, OK - maybe he succeeded, but it was long time ago and no one has replicated it yet. Well, maybe he already replicated it, but he hasn't published it in serious scientific journal! Well, shit - maybe some journals about it still exist, but they're not peer-reviewed...!! ..Jeez, some of them are possibly reviewed - but they're of low impact and they didn't pass the scrutiny yet - that's it!!!

    This discussion is not relevant to anything I was talking about, but it's setting up a strawman through insinuation. The topic we were addressing: is there a "lab rat" experiment that can be used to gradually characterize LENR? My response, and probably the opinion of most serious workers in the field, is that there is not such a lab rat experiment yet. In order for an experiment to be a genuine lab rat, it would have to be something that independent labs are able to pick up and run with. You won't know that until independent labs actually do pick it up and run with it.

    This discussion is entirely apart from the question of whether LENR is real.

    The copious evidence of cold fusion is exactly the opposite: not only the Coulomb barrier gets broken, but also symmetric process happens: the resulting energy gets miraculously dissolved within atom lattice.

    Cold fusion has many possible explanations, only some of which involve fusion. Your reply to my points is general and glosses over the specific objections with vague possibilities. We must move beyond hand waving and rigorously consider specific details.

    This is misinformation - such an experiments are already there: for example prof. Hagelstein and Swartz from MIT sell NANOR® kit, which enables to start the cold fusion experiments with 100% reliability.

    Claims of having a lab rat experiment are very different than actually having one. Can you refer us to various groups that have made use of NANOR's kit to gradually characterize LENR? (Preview of your answer, should you answer directly: you can't.)

    What other simple systems would you consider "lab rats"? Claims by the originators are not sufficient to bestow this label upon an experiment. Note also the important requirement, mentioned by me above, that the phenomenon exhibited by the lab rat be well above the noise floor.

    And there are another simple systems, which already provide very good reproducibility (codeposition of palladium for example).

    This is an example of a promising set of experiments in which the original team had placed a lot of hope for it being a lab rat, but whose unambiguous replication has nonetheless not been forthcoming. I would not call it a lab rat at this point.

    On the experimental argument, I largely agree with THH. It is a shortcoming that must be addressed that there is no "lab rat" experiment that can be easily replicated, with results well above the noise floor. Hopes have occasionally been raised over the years that such an experiment might have been found, but such hopes have not yet come to fruition.

    On the theoretical side, I am largely persuaded that unexamined assumptions and misinterpretations of what expetiments there are abound, both among CF'ers and among mainstream physicists reviewing the body of work from afar, and that through polemics these bad assumptions have been partly codified into a CF dogma, a situation that has helped to lead theory building astray. It does not matter what an intelligent mind such as Peter Hagelstein comes up with if important starting assumptions are incorrect or are experimentally untested. If CF is eventually accepted into mainstream science, I assume that all that will be needed will be some minor adjustments to and elaboration of existing physics and one or two happy coincidences in areas of experimental physics that were up to now poorly explored. There are surely tantalizing possibilities that students of nuclear physics will have stumbled upon in their studies generation after generation, only to be told by their professors with a little too much confidence that while the idea is an interesting one the experiments do not support it. It is in such possibilities that I find the most promising avenues for an explanation for LENR.

    The possibility that radioactive decay rates might be modulated is one such possibility. The idea will have occurred to any physics student after learning about the Gamow theory. The fact that the possibility is raised as a question from time to time on is an indication that the suggestion is not a radical departure from existing physics. There is even a page at MIT that documents a number of (non-CF) studies that have been done on variability in decay rates. If radioactive decay could be accelerated, many CF experimental findings could be explained. There may be one or two other such possibilities.

    The same people oppose the hydrino subquantum level the most - what actually prohibits the electrons to get closer to atom nuclei? They could only gain energy with it.

    The argument against Hydrinos is not based on the possibility of the electron existing part of the time in the nucleus. Indeed, in Mills's telling, the electron orbits in a two-dimensional plane, with the implication that it would never transit the nucleus. The QM argument against Hydrinos goes back to other difficulties.

    Only if these photons scatter off electrons from outside the atoms, i.e. during excitation from surface to bottom. The energy density is low there or the individual electrons will get ejected to high orbital paths. But how the situation would differ during excitation of electrons from bottom up? The excitation of single electron would require the collective excitation of many others. And as I illustrated above, these bottom electrons can be tough chaps. It's like to draw out a single branch from bottom of pile of brushwood.

    You seem to be arguing that MeV energy photons will somehow be channeled and thermalized by scattering off of electrons in condensed matter, despite the copious evidence that the opposite of this is what generally happens, namely that even heavy metals are largely transparent to photons in this range of energy. You posit a highly dense phase of matter to pull this trick off, and now suggest that it might be possible to cause collective excitations of electrons. It seems to me that the unsupported assumptions must continue to accumulate in order to go further down this path.

    This is a difference: You should guide the gamma rays only to absorb them more effectively.

    If we're talking about efficient absorption of the MeV photons and not simply the guiding of them, e.g., in a linear trajectory out of the host lattice, our difficulties multiply. Each time one of those photons scatters off a nucleus or electron, it will either lose very little energy, or it will put the system in a state that will result in the further emission of energetic photons in arbitrary directions.

    The quantum mechanics prohibits the electrons to get very close to atom nuclei.

    There's nothing in QM to prohibit electrons from spending time in atomic nuclei; in fact, in the case of s-wave electron orbitals the assumption is that this is happening part of the time, and electron capture requires that it happen.

    Alan, I assume that even if MFMP had the right paint (which would be nice), the outcome of their emissivity test will nonetheless depend upon the thickness of the layer of paint, which is an unknown quantity?

    OK, this is written there - but do you understand its mechanism? If the physicists don't understand something, they always promote a new particle.

    I do not understand the putative mechanism in the present context. Suggesting that an atomic lattice can be used to guide 0.5 - 24 MeV photos is like suggesting that a small block of aerogel can be used to guide 50 caliber bullets. But let's assume for the sake of argument that the jet quenching has a cross section for photons of this energy range. The cross section will still be finite. If you have 1 W power, that will be in the neighborhood of 1e12 reactions taking place per second. If even a small fraction of those reactions resulted in photons that escape that are not somehow guided by the presumed jet quenching, the number of detectable photons escaping the apparatus would be large.

    But there are yet other difficulties: the dd → 4He + γ pathway is normally inhibited.

    But the gammas aren't channeled with ordinary condensed matter during cold fusion - but with highly packed atom nuclei.

    I'm going to wager that you'd need matter with the density neutronium to make a difference. But let us assume that there are such highly packed nuclei and then enumerate the assumptions we've got so far:

    • During an event, there is something that happens to pack the nuclei tight enough to guide MeV photons
    • The atoms are able to produce jet quenching in the photons in a phenomenon that is otherwise known only to occur at energies associated with hadronization
    • The process of jet quenching in this context is efficient to many decimal places, and as a consequence any stray photons are at the noise threshold
    • Somehow the d(d,γ)4He branch is favored enough not to see large numbers of neutrons
    • A lattice that has a binding energy in the eV is somehow able to bring together deuterons over a potential barrier in the MeV

    If the excess heat is high enough it would not matter taking an upper limit.

    I think this is an important point. Any experiment that is in or barely above the noise is not going to be very persuasive. By contrast, if an experiment can be found that is consistently well above the noise when carried out by independent labs, that will be a very positive development.

    The high energy physics knows phenomena like the jet quenching: during particle collisions the resulting beams of gamma ray and energetic particle fragments get suppressed. This happens when the particles collide in collinear way, so that the quark-gluon condensate gets formed - but at much higher energies above 200 GeV, At the opposite side of energy spectrum inside the boson condensates so-called the Anderson localization applies - but the cold fusion is boycotted research and the thermalization mechanism is studied even less, than the mechanism of Coulomb barrier suppression.

    Jet quenching pertains to partons. In the range of energies we're talking about, e.g., 500 keV to 24 MeV, there will be nary a cross section for hadronization and related phenomena. Instead what can be expected to happen will be what usually happens: the crystal will be mostly transparent to the photons and will allow them to pass through in any arbitrary direction, rather than serving as a waveguide. Or do you have any reference in the literature for photons in the 500 keV to 24 MeV being channeled by ordinary condensed matter?

    Whereas during cold fusion the gamma rays are conducted along entangled atom nuclei, which serve like the waveguides. The internal reflection mechanism applies in this case.

    Your contention appears to be that a linear array of atoms will serve as a waveguide for MeV-energy or even 500 keV photons, rather the usual behavior, which is to be mostly transparent to these photons. Is there anything in the mainstream literature that supports this contention at the energies we're talking about?

    I also explained it: the mean free path applies to metal lattice, which is actually very sparse environment due to large spaces between atoms. ... But once the X-rays impact the metal lattice under low angle ...

    Forgive me if I have not read an earlier contribution where you addressed this point; I rarely even skim your posts, as I find little redeeming in them. But to your point: at even one or two orders of magnitude less than 24 MeV, our photons are too energetic to participate in the kind of x-ray mirror you're describing. Some cutting-edge efforts at hard x-ray optics, for example, are focused on a 80 keV upper limit. In order to have your mirror, you will need to have already broken up that 24 MeV quantum into small pieces.

    Strong force can be opposing...

    Yes — at less than 0.7 fm between the nuclear centers, the nuclear interaction becomes repulsive. But the fusing nuclei must first drop off that cliff and land at the bottom before this opposing part of the strong force kicks in, at which point a lot of kinetic energy has been added to the system and resulted in an excited compound nucleus. That excited nucleus will now rapidly decay to the ground state through one or more (often gamma-producing) transitions, or it will break apart into two fragments as in the case of dd fusion. So I don't think the repulsive part of the potential curve you're talking about will help us out here.

    Imagine holding the two large magnets from the video in your hand and trying to bring them gradually closer together until they touch, without letting them snap together violently.
