  • The Totally Civil Covid Thread. (Closing 31/05)

    Quote from Alan Smith



    Wuhan market samples shed no more light

    Hopes have been dashed that genomic data from swabs collected in the early days of the pandemic will reveal the origins of COVID-19. Data from the swabs, collected by the Chinese Center for Disease Control and Prevention, have been analysed by three teams, but each has failed to pinpoint which animal species — if any — infected people at the market. “I would basically describe this as a negative result,” says Jesse Bloom, the virologist who conducted the latest analysis.

    I wonder if there's anyone left still waiting for evidence to say if the bat soup hypothesis-fantasy was ever true.

  • Device for registration and investigation of Lenr manifestations in conditions of diaphragm discharge

    Appreciate your willingness to deep dive in this topic. I just wanted to point out that Ken Shoulders work is not at all shunned by LENR-forum, in fact we even have available for download “A Tale of Discovery” in the USEFUL BOOK THREAD.

    THE USEFUL BOOK THREAD
    One of the things that Mizuno replicators are going to have to get to grips with is Vacuum systems. I must confess that my experience has been limited to 'roughing pump' territory and I found this free book (which is around $150 on Amazon) really helpful.

    Particularly useful perhaps is this section.

    We are also aware that Takaaki Matsumoto realized the importance of Kenneth Shoulders’s work and recognized that EVOs / Ball lightning were at the core of LENR, which was recorded for posterity in a letter exchange published in Fusion Technology.


    That said, the problem for a wider acceptance and understanding of this important knowledge is that Ken’s work is complex and completely against the grain of mainstream knowledge, hence is met with silence, mostly. I don’t recall at which ICCF Kenneth attended and presented his conclusion that the key to LENR was the EVO. He was largely ignored. A shame, but also a fact.

    I have seen similar formations being shown as formed at the micrometer scale in the samples prepared in the “VEGA” experiment that is an analogue of the SAFIRE reactor.

  • Italian Contribution to LENR

    A new paper by Carpinteri finds LENR in Gypsum and Quartz fracturing.


    Abstract

    Extensive experimental investigations were conducted on Gypsum and Quartz compression specimens of different sizes. They were brought to complete failure, showing two different failure modalities: (1) Very brittle loading drop for micro-crystalline Gypsum and Quartz; (2) Stable strain-softening behaviour for macro-crystalline Gypsum. All the tested specimens emitted acoustic and electromagnetic waves and the single events cumulated up to the peak load. On the other hand, neutron emissions were evident only for the largest specimens. The significant chemical composition changes occurring on the fracture surfaces are consistently explained by the assumption of Low-energy Nuclear Reactions (LENR), both fusion and fission. It is the first time that fusion reactions emerge from crushing tests, whereas fission reactions have already consistently explained the results related to other materials like the iron-rich natural rocks. Therefore, a correlation emerges between fusion nuclear reactions and strain-softening mechanical behaviour, as well as between fission nuclear reactions and brittle mechanical behaviour.

    I post it here to highlight that one of the aspects they state will be explored is “In our project we will combine an electro-chemical cell with ion beams for deuterium loading and defect engineering of palladium.”be which is the topic that interests us in this thread. Its interesting they are attempting to engineer the cracks on the Pd lattice as one of the aspects of their research.


    This description makes no sense. This word salad. I have no idea what "defect engineering" means. Also, cracks are NOT THE SITE of LENR. The sites are gaps having a critical dimensioin. The details are important yet getting the details understood seems to be impossible.

    Well probably my understanding that cracks are what cause the gap is totally wrong then, yikes!. Are the gaps associated then to what process?

  • Conventional Nuclear (AKA Nuclear Fission) a thread for discussion of the pros / cons.

    This is what I mean by inherently safe when talking about Liquid Thorium Fluoride Reactors (LTFRs):


    Safety Features

    Molten Salt Reactors, and by extension LFTRs, have several very attractive safety features. First, and most importantly, is the negative coefficient of reactivity. This means that as the temperature in the reactor increases, the rate at which the fission reactions proceed decreases. This will self-regulate the temperature in the fuel salt and prevent the reactor from going prompt critical (i.e. blowing up). [2] It is worth noting that the coefficient of reactivity for the reactor shown in figure 1 would actually move from negative to positive due to heating of the graphite moderator. [2] LFTR designs generally do not have a graphite moderator.

    In most MSR designs, there is a freeze plug safety mechanism built into the reactor plumbing. If the plug were removed, the reactor salt would flow down into holding tanks. A freeze plug needs to be continuously cooled to prevent it from melting and thus allowing the salt to flow out of the reactor. If power to the MSR facility were removed, say due to some natural disaster, the reactor would power down without the need for any human intervention.


    Quoted from Stanford University LFTRs page.

  • Conventional Nuclear (AKA Nuclear Fission) a thread for discussion of the pros / cons.

    Safety is clearly the main concern, and as Stone correctly points, we have decades of Hollywood fear porn propaganda that makes nuclear guilty by default.


    That’s not to say is not a true concern, and in my country, being it arguably the most seismic country in the world, nuclear power has been studied and discarded for good, as we get too many strong EQs, too often.


    The question is as often of balance, and the NRC taking things to the extreme of making nuclear power a stagnant field compared to China’s booming nuclear plant building makes one wonder what is the proper balance.


    And because of this I must go back to the Liquid Thorium Fluoride reactors, fully developed in the 1960s, and with inherently safe design to stop the reaction as the natural state of the reactants prevents the reaction to proceed in case of a total power black out. One can only wonder why this never became a commercial reality.

  • Comprehensive Review of Cold Fusion - It's not pathological science!

    We had already posted a brief review of this paper by Brazilian Nuclear Engineer and ICCF 23 participant Luciano Ondir in the Last newsletter of 2021. It is really good so great that Dave Nagel has noticed it.

    Quote from Curbina

    Brazilian Nuclear Energy Researchers officially join the LENR field with a strong claim:

    A team led by Dr. Luciano Ondir Freire (Instituto de Pesquisas Energéticas e Nucleares (IPEN-CNEN/SP), Nuclear Engineering Center, São Paulo, Brazil) has published recently in the Journal of Electroanalytical Chemistry the review paper "Preliminary survey on cold fusion: It’s not pathological science and may require revision of nuclear theory". This extensive review paper has thoroughly assessed the 30+ years of LENR research to conclude that it is a valid and potentially ground breaking research field in spite of the controversy, and that it may lead to revise accepted nuclear models. Dr. Luciano Ondir participated in ICCF 23 as expositor with a Poster Presentation. You can join the discussion of this important paper at the following LENR-Forum thread: Brazil Joins the party- a survey of the LENR field.

    We have also a link to the paper

  • Conventional Nuclear (AKA Nuclear Fission) a thread for discussion of the pros / cons.

    Jokes apart, I really think Oliver Stone has not a clue about what LENR is and if he knows something about cold fusion is probably wikipedia deep. The current push for nuclear, unfortunately, has a lot more political drive than a technical one, and we all know currently politics use first and foremost emotional arguments, while technical aspects become secondary.


    I think we could all be enjoying fission nuclear abundance if Thorium reactors research (tested succesfully at the MW scale in Oak Ridge facility in the 1960s, and even to power prototype airplanes) would have not discontinued.

    Quote from JedRothwell

    I think in some instances, on rare occasions, the spots are melted. That is what Szpak reported. I hope this seldom happens, so the material generates power for months or years before it has to be replaced. If the material is inexpensive Ni or Ti, I suppose you could make the cathodes much larger than needed. You could operate at only ~10% of potential efficiency measured in surface area. It would take a long time to degrade down to 9%, when it has to be replaced.

    But how we make a material with 10% of active surface area? Do we even know how much % of active area is available in these materials? I think that those are the questions that we need to answer and for that we need to know more about the active cracks.

    So, back to the cracks and their

    size and configuration. Storms , do you think that is possible for a crack to remain stable for the process to happen many times on the same crack, or that is really a transient property of the material and that is key that the material be able to form these cracks again over and over as the process advances? I ask because I am thinking in the observations of Fralick in 1989 in the Johnson Mathey Hydrogen Purifier with the PdAg tubing and their 2020 revival and deeper exploration by Benyo et al. There are others that, inspired by that original Fralick work,

    have seen similar temperature rises in experiments of D passing through a Pd film, and there’s also a similar result with H diffusing through a Nickel tubing done by the people of BrLP in the early 2000s. How do you interpret these results from the crack size perspective? Can we harness this kind of systems or these are just flukes?
