The New Fire MK1 – A controllable reaction driven and moderated by heat, pressure, element ratios, phase states and morphology…

by Bob Greenyer

Piantelli says that Nickel must be above a pre-determined lower temperature, evidence suggest this to be Debye if Ni.

Piantelli says that you need to create H- and then use an impulsive action to force it into the Nickel. (http://goo.gl/ORrJqI) This forms the primary reaction, the “mouse” and from our Celani experiments, a COP of around 1.1. It comes from the transmutation of Ni isotopes.
By forming LiH at 250ºC from LiAlH4 in the Rossi system you create a LOT of H- (which is the first novelty) because LiH is a ionic solution (Li+ H-), all you have to do is kick it into the Nickel by raising the temperature more – which sounds a little weird, but remember you are trying to stimulate a Nuclear process from a low energy thermal one.

From wikipedia, you get the key to the Rossi process. https://en.wikipedia.org/wiki/Lithium_aluminium_hydride
2 LiH + 2 Al → 2 LiAl + H2 (R3)
R3 is reversible with an equilibrium pressure of about 0.25 bar at 500 °C

Note that in the Industrial Heat patent application, it says you need a pressure of 0.25 bar (goo.gl/tFX6Qa) – but the actual reversible reaction is dependent on pressure and temperature as says wiki – so for Parkhomov 2cc of dead volume, 0.5 bar and a different pressure/temp regime may work.

According to Piantelli, some of the protons from H- fail to transmute Nickel and get ejected as protons from 0 up to 6.7 MeV (measured in cloud chamber and calculated). As Unified Gravity Corporation (UGC) has shown (http://goo.gl/8GKvWb) with earlier Lipinski work on same effect cited in latest Piantelli patent dating back to August 18th 2006 (http://goo.gl/jJ71mL) you only have to accelerate a proton to less than 225eV into Lithium target to yield around 15MeV and 2 He from 1H + 7Li. This is the secondary reaction – the “Cat”. In this system, only Nickel that ejects a proton (and therefore participates in the overall reaction but is unchanged) is truly catalytic – it is this authors conjecture that under the right circumstances 62Ni will be mostly catalytic – or catalytic in the sense of Carbon in the 12C carbon cycle that is to say, if it does accept a number of 1H, it ends up returning to 62Ni.

Both UGC and Piantelli in their specific embodiments, use a low pressure environment to allow the protons to travel the distance to the Lithium before the break down. The second apparent novelty in Rossi’s reactor is to have the Lithium in direct contact with the Ni as MFMP discovered following “Bang!”. However Piantelli words his patent to cover this:
“It is relevant that the secondary material faces the primary material, since, if a further material is present between the primary material and the secondary material, the protons would not go beyond this further material and would not reach the secondary material.”

This statement covers lithium in direct contact with Nickel and the patent has a priority date of Apr 26, 2011.

Therefore, UGC have shown that low energy Protons can create Fusion/Fission of 1H and 7Li. Piantelli has provided the Proton accelerator.
The third apparent novelty (inferred by this author) in Rossi’s reactor is the “inherent safety” which works over a massive range of temperatures. It is this authors suggestion that this is due to the breakdown of LiH. In part this process initiates the primary reaction by impulsively forcing H- into the Ni at the molten LiH : Ni boundary as noted above. However, at high temperatures, either caused by heat from the primary/secondary reactions or from deliberately over heating the reactor the H- is all driven out into H2 outside the Nickel with Li in between, A small amount will be in Nickel. This will subsequently allow the reactor to rapidly be cooled down and ready for re-start.

The amount of Lithium used will lower Li Al melting and LiH formation / destruction dynamics. Piantelli has also said that the secondary material must be an alloy, one embodiment suggested is Li and Al . He says that it must not be crystalline but in an amorphous state, a liquid solution of these two metals meets this need without the requirement to cool at 1000ºC per second.

So reasons for for active heating in relation to Rossi reactor is:

– Maintain Ni above the minimum temperature to enable primary reaction, assumed to be Debye of Nickel
– Maintain the secondary materials in an amorphous, (not solid/crystalline) structure – in this case, liquid
– Allow for thermally driven creation and destruction of H-
– Provide impulsive action to drive available H- into Ni clusters
– Provide active, heat driven shut down of reaction by forcibly removing H- from the Li and keeping it away from Ni

Low pressure is required to allow somewhere for the H- to be released from the LiH to make H2 reservoir that can later be used to make LiH at will.Adding extra Li will change the melting point of the mixture as well as provide more secondary fuel (See http://goo.gl/JM1UPx).
Important to the process is that Lithium has a Specific Heat Capacity of 3.56 at 25oC in J/goC and H2 has 14.267 – together, they allow for effective engineered ways of getting heat out of the systems main heat source, which is on the boundary layer between Ni and Li.

NOTE: the above may be materially wrong and is posted for education and debate purposes.

  • Adam Lepczak

    Humanity at its finest…Bob, could you also come up with the practical roadmap for the replicators? Bill of materials with links?

    • Bob Greenyer

      Yes – I have an animation job to get out of the way (have to pay the bills somehow) – but I think another collaborate is in order, get everyone in one place to pool best practices and plan the programme.

      Certainly the Li content/dead volume/pressure relationship around the reversible reaction (R3) could be characterised in GS2/3 type cells and there is no need to look for XS heat – we just need to draw up tables for when LiH is made and destroyed under the influences of materials ratios, temperature, pressure, dead space and also LiH formation promotors such as small amounts of carbon.

  • ss dd

    Nice write up Bob! Understandable by someone like me who doesn’t have much physics background.

    My thoughts:

    Looking at the 3 reactions of thermal decomposition of LAH, if you start with 6LiAlH4, you end up with the following equilibrium:

    6LiH+6Al 6LiAl + 3H2 (R3)

    Moreover, you have an extra 9H2!

    According to your write-up, we would want to create lots of LiH. My layman understanding of chemical reactions such as AB is that if you have an equilibrium and that you want more “A”, then you can add more “B”.

    But look, H2 is already abundant so we just gotta add more lithium! Hence Rossi adding more lithium to his formula. In what form would that lithium be? How would it react with the extra H2 to form LiH? What conditions would favor that reaction?

    • Axil Axil

      The analysis of the Lugano fuel load showed that Rossi preheated and sintered his COTS nickel powder to produce 100 micron nickel particles and he added lithium to the pre-heat reaction at the fuel prep stage.

      • Jonas Matuzas
        • Mats002

          Those Russians! They do clever things with almost nothing.

          • Alain Samoun

            Except that they are Ukrainians I believe…

          • magicsnd1

            They didn’t consider the higher thermal conductivity of hydrogen vs. air. So though it looks nice, It’s flawed calorimetry.

          • Jarea

            What is the error tolerance for that flawed calorimetry?

          • magicsnd1

            The thermal conductivity of H2 is about 7 times that of air at 400 °K. To calculate how that would affect the thermal equilibrium we would need all the dimensions of the device as well as the input power and pressure data.

            Adriano Bassignana also pointed out that the glass tube and water bath are mostly transparent to IR, so the water is heated primarily by conduction through the glass tube. An opaque (black-body) container for the water bath is needed to capture the radiated portion of the heat output of the device.

          “According to Piantelli, some of the protons from H- fail to transmute Nickel and get ejected as protons from 0 up to 6.7 MeV”. How can they reach 6.7 MeV before reactions with Ni and Li? Here there is a key passage lacking…

          • Bob Greenyer

            Well – by observation and apparently calculation based on “coulombic repulsion” apparently – but it is still a bit of a leap! That is a LOT of energy – and would pretty much react with anything it hit.

            Do we have to invoke epicatalysis, meta materials, vortices etc etc. maybe…

            actually we only have to get to <225eV – that is still quite a bit though – can't get that from any one chemical thing.

          • Axil Axil

            6.7 MeV is the binding energy created when nickel is transmuted to copper through fusion. The appearance of this energy means that nickel/hydrogen fusion has occurred but has not been thermalized by the basic LENR process.

          • Bob Greenyer

            Very good.

          • Axil Axil

            The breakdown of the basic LENR energy process is caused by a cooling that destroys the entanglement between the fusion site and the SPP. Fusion energy transfer occurs through entanglement and quantum teleportation. Entanglement is caused by heat photons or the plain terms equal temperature between the fusion site and the SPP.

            The SPP is a black hole that has its own Hawking temperature, Hawking radiation is black body radiation that is predicted to be released by black holes, due to quantum effects near the event horizon. When this temperature level is disrupted, entanglement is destroyed and LENR energy transfer does not happen. Gamma radiation is then produced.

          • Bob Greenyer

            And the way the average garage experimenter can test for this is?

          • Axil Axil

            Piantilli has done this test already. He showed that temperature level was the cause of gamma production. A tipping point temperature will mark the transition point between gamma production and radiation free LENR operation. That temperature tipping point will be common between most LENR experiments no matter how different the systems are.

            That temperature will be found to be the Hawking temperature of the SPP black hole.

          • ecatworld

            Thanks for the comment, RLittle — unfortunately there is some issue with the links you provide. Could you repost them without adding parentheses or extra formatting. Disqus will shorten them, but they should resolve fine.

          • I have heard theoretical presentation at ICCF19, starting with such assumptions (1^16 tesla sometime).

            This is huge macroscopically and would destroy everything around if static, end even worst if dynamic. Even blackhole and pulsar don’t show that kind of macroscopic field.

            however the local field inside an atom, inside a nucleus may be huge over tiny dimension.

            another reason to accept it was told by Srivastava, it is that the EM field may be caused by an evanescent wave. (NB: magnetic or electric field are dual… both have to be huge)

            http://www.prometeon.it/download/Yogi%20Srivastava.pdf

            I cannot judge if those explanation are reasonable, and I may have misunderstood some.

          • Axil Axil

            The basic LENR process usually stabilizes unstable nuclei after a fusion reaction through a energy transfer and thermalization process. When Plaintiff takes the nickel bar out of his reactor, the nickel bar cools below the temperature necessary for energy transfer to occur and the nuclei stays excited. This unstable isotope will release energy via proton ejection.

        • Bob Greenyer

          Yes, Bob Higgins and I have discussed this at length when he reviewed the Lugano data again.

    • Bob Greenyer

      All variables to try – Axil Axil suggests one approach.

      • Axil Axil

        I am not segenting this process, the fuel prep process is what Rossi did.

        • Bob Greenyer

          where was this documented.

          • Axil Axil

            It is evident from an analysis of the fuel description including micrographs of the fuel presented in the appendix from the Lugano report. Take a look.

          • Bob Greenyer

            Could it be milled together?

          • Axil Axil

            The fine nanostructure of the COTS power was not disturbed. I had to be sintered, Heat welded the 5 micron particles together.

      • ss dd

        Each LiAlH4 molecule contains 4 times as many H as Li. So if we want to maximize the LiH we’d want to add way more lithium from another source and make sure it reacts with all the extra H2.

        • Bob Greenyer

          That too.

          Bob

      • ss dd

        Also, (you probably know all this)

        2 Li3AlH6 → 6 LiH + 2 Al + 3 H2 (R2) occurs at 200 °C

        Then as you increase the temperature, that extra H2 can be used for:

        2 Li + H2 → 2 LiH

        For the above reaction, wikipedia says: “This reaction is especially rapid at temperatures above 600 °C. Addition of 0.001–0.003% carbon, or/and increasing temperature or/and pressure, increases the yield up to 98% at 2-hour residence time”

        So we’d want a few hours to form as much LiH as possible… Would carbon be a catalyst?

        Then are we saying that we want to go above LiH’s melting point (688C) so that it reaches the nickel? Or do we need to reach its decomposition point at 900-1000C?

        • Axil Axil

          A muon track could look like a proton track in a cloud chamber. How can you tell the difference?

          We can use a magnetic field to see which way the particle bends, either positive for the proton or negative for the muon. I don’t think that Piantelli has proved the the particle he is seeing is a proton. It could be any number of other subatomic particle types including mesons.

          We only see what we want to see. Just because Piantille thinks he sees a proton does not mean that the track is from a proton.

          • Bob Greenyer

            He would’t make that mistake.

            Lets assume he did though!

            The ash he has seen as a result of 100s of experiments with Focardi et al and since, the intermediaries, the decay products all come from proton interactions.

            We can say everything in the world works a different way because it displeases our view, but if you see say zinc – where oh where did it come from – did it teleport into the ash?

          • Axil Axil

            But what produces what? Muons could produce proton nuclear reactions. Protons must be involved because neutron are not. But what catalyzes the fusion of one or more protons into nickel? I say its muons. What is the cause and what is the effect?

          • Bob Greenyer

            Piantelli has a theory, it doesn’t include Muons – only that H- acts as a “virtual muon”.

            Others have other theories.

            Piantelli and Focardi checked their understanding in 100s of experiments.

            Here is a riddle for you, which are fermions, which are bosons

            H
            H-
            D

          • Axil Axil

            Piantilli came up with the H- idea because he could not imagine in his widest dreams how a muon could be created by the basic LENR process. If he knew that there were tons of muons flying around in the LENR reaction he would have assumed that the fusion was caused by muons.

          • Bob Greenyer

            So why then does Rossi’s reactor rely on a reversible process involving Li Al and H2 that creates and destroys H- and that starts to function at the first temperature that H- is formed.

            Why not get rid of the aluminium and hope for the best?

          • Axil Axil

            DGT, Holmlid, and Rossi’s low temperature reactors used potassium…no aluminum involved. You replicators are so narrowly focused on the current system you are interested in. This is a weakness in your thinking. No offence intended, just tough love.

          • Bob Greenyer

            Not sure that answers the question

          • Axil Axil

            All these systems produce Rydberg matter that generate muons as shown by Holmlid. Rydberg matter formation is a alkali metal process. LENR is centered on Alkali metals in its Rydberg matter form.

          • Bob Greenyer

            Now, being theory agnostic (you may laugh) I buy the Rydberg matter and the importance of Alkali metals from your post.

            I admire the work of Holmlid and pointed Celani to it many moons ago.

            You will see our discussion on catalysis on our main site.

          • Axil Axil

            If you buy Rydberg matter, you get muons whose formation and effect that I predicted many moons ago,

          • Bob Greenyer

            Whilst this is an interesting aside, I am still waiting for an answer to

            “So why then does Rossi’s reactor rely on a reversible process involving Li Al and H2 that creates and destroys H- and that starts to function at the first temperature that H- is formed.

            Why not get rid of the aluminium and hope for the best?”

            Additionally

            Why also does IH/Rossi want to buy Piantelli’s patents when really he should be interested in Holmlids?

            Why does he contest Piantelli’s patents if they are irrelevant?

          • Axil Axil

            The Lugano report proves that the LENR reaction does not involve H-. The nickel transmutation whent from Ni58, Ni60, Ni61 to Ni62, The Lithium transmuted from Li7 to Li6. The neutrons from the lithium were transferred into the Nickel.

            Out of the thousands of LENR experiments done, there is no rhyme or reason for the how transmutation works it is effectively a random process. Transmutation occurs in systems that don’t have hydrogen in the mix.

            The theorys of LENR that use hydrogen as the reaction activator can’t explain results where transmutation occurs when hydrogen is not involved in the system.

            What about the transmutations that involve fission of heavy elements like uranium and thorium into lighter elements. These fission reactions occur concurrently will fusion reactions.

            This is way the theories by Ed Storms, Godes, Piantelli, and Rossi are wrong…because they use hydrogen as the key factor in the reaction.

          • Bob Greenyer

            Hi Axil,

            Yes – as I have said countless times over the past few days (and even asked Tom to do the math) – there is the 7Li + xNi > 6li + (x+1)Ni potential reaction as favoured by Upsalla University – that is why it is so important for Bob Higgins to get the {Garbage Can} experiment running – the main point of which is to look for helium, which, depending on the resulting ash, would help define the underlying nuclear interchanges.

          • Bob Greenyer

            haha – just did a rough calculation – 20% of Li & 30% of LiAlH4 by WEIGHT gives you 94.1% of the atoms as Li 5.9% as Ni – which gives you a melting point of around 250ºC

            This links Rossi’s patent (example fuel ratio) with IHs application (reactor operating range).

            Note: Someone please verify

          • Axil Axil

            Don;t you mean 5.9% as Al?

          • Bob Greenyer

            I changed that thanks – I did have it wrong in first posting – just working late again!

          • ss dd

            As opposed to 50/50 when using only LAH, which would have a melting point around 700C? Is there an advantage to having Al-Li melt at a lower temperature?

          • Bob Greenyer

            Yes. the Li needs to be molten on the Ni

          • Axil Axil

            “So the magnetic forces between the e- and p+ and the metal nucleus for very close nuclear approach of the hydride species to the nucleus of a metal atoms is on the order of 1010 X 1000 tesla or 1013 tesla. Therefore within the s orbital of the metal lattice, the e- and p+ of the hydride species would locally experience tremendous magnetic fields on the order of the magnetic fields in magnetars.”

            This is what I have been saying. But I thought I was the only person with the Cojones to say so. 10^^13 tesla was the number I had come up with as the magnitude of the magnetic field required to produce mesons from the vacuum. Congratulations. You are a great LENR pioneer. You are on the right track even though your mechanism for power concentration and magnetic projection is off.

            That magnetic magnitude is startling and because of it, I will read your patent with great interest.

            WOW, “magnetic fields in magnetars.” that is me.

          • RLittle

            Hi Axil,

            Thanks at least for not insulting me. It is usually at this point that people get mean and say things that are not courteous. I wish you well in your endeavor.

            RBL

          • Bob Greenyer

            I did say that there maybe material errors!

            Hank Mills seems to have pointed out that the reference for the pressure requirement of the R3 reaction is only in Wiki. Honest I don’t have any inside info. I just need more sleep!

            Thanks Hank for demonstrating peer review in open science debate.

          • builditnow

            RLittle, experimenters need your guidance and suggestions.

            Thanks for having the courage to express your theory. Nuclear physics is not my field, however, LENR is a multidisciplinary field requiring may participants who have more or less understanding of each other’s expertise.

            Right now, we open source experimenters are operating on tiny budgets with assembled volunteers of assorted skills. Many are geniuses in their sphere of knowledge and skill. With the resources we have, all these experimenters need ideas on the experiments that can be tried, often, by using used “junk” lying around or that can be “scavenged”. You can see the Russians are very good at this, out of necessity, but, others are too, all over the world.

            These experimenters need your guidance.
            What exactly to try.
            From reading above, 10^13 tesla is a head blowing (beyond mind blowing) magnetic field strength. Is there any possibility that externally applied magnetic fields could have “any” impact, and, if so, how strong a field and for how long? My first thought is to go for the most intense magnetic field possible by shorting a very low inductance capacitor on to a low inductance coil as often as possible. Is there any benefit in changing the field direction, or, should it be in the same direction?
            Resonance is all a thought, what kind of frequencies might achieve resonance?

            Would the magnetic field from heating elements have any impact?
            If you could find a space on the web, perhaps lenr.org where you could write up your suggestions for experiments, then come here periodically and remind the experimenters where to look, you could add you piece to the puzzle and, your theory might become the Big Little Effect 🙂

  • Bob — I like your hypothesis, and it’s interesting how it builds on both Piantelli’s knowledge and a series of observations including the Lugano experiment and Rossi’s small talk.
    If this is close to reality, then the beauty is this — Rossi (and Piantelli and others) have spent years of hard work to find these clues and parameters, and you and MFMP have done a great job, together with your community, to lay the puzzle and reverse engineer parts of that information. Both accomplishments are impressive, and hopefully we’re now closer than ever. It will be interesting to see how things play out!

    • Bob Greenyer

      For sure. It would be good if the parties would play nice together – but hey ho.

      The coming period is going to be interesting.

  • ss dd

    Could it be that the realization that Rossi had after Lugano is that he was wasting a lot of his H- by using Ni58/60 in his fuel, and thus switched to using Ni62 which doesn’t steal the H-‘s?

    • ss dd

      Therefore reusing Ni62 rich ash as fuel and remixing that with LiAH and Li would create a more efficient reaction than in Lugano, which would create the extended periods of SSM that Rossi’s been mentioning in 2015.

      • Bob Greenyer

        Yes.

        And that is what one of the Russian team suggests – for this reason.

    • ss dd

      I thereby submit as public knowledge the following process: do a first run in the apparatus as described in the Rossi patent from Aug 25, 2015. Reuse the fuel and mix with more LAH. This should increase the COP, SSM periods, and duration of fuel.

    Un-pealing Sellotape in a vacuum creates 15 kilo-electron volt x-rays you can take an x-ray with!

    From Vortex

    http://goo.gl/9jzFNV

    First discovered by Russians in 1953 and now re-discovered, the penetrating radiation is generated by charge build up and release in the AMORPHOUS glue and there is a suggestion that it could be enough to trigger Nuclear Fusion.

    Perhaps the easiest LENR experiment is to dust a little fluorine stabilised Lithium powder on some scotch-tape, wind it up, put it on two spools in a low pressure/near vacuum H2 environment and unwind the sticky stuff.

    And we’re worried were we can get energies under 225eVs?

    Note: Could this be the first time Nature mentions cold fusion in modern times?

    • Mats002

      OK, we are on to something here, it is even possible that discussions below actually advances the LENR field, that would be something!

      Nevertheless – we must focus on the NiH GS system until LENR+ (useful energy gains) is obviously demonstrated. The gap between practical experiments and deep underlaying causes is secondary for the moment.

      Tough love Axil!

      • builditnow

        Mats002, I’m with you on focusing on the NiH GS looking for LENR+.
        However, if Axil has experimental suggestions, no harm in that, especially if it’s something we can do with our current talent and equipment.
        So, Axil, I’d especially like suggestions / enhancements around the NiH systems, things that we can do. And I do like your theories and broad overview of the field, but, I can’t do much until I get that $1 billion government contract (like that will ever happen LOL ).
        If we can get a 5 to 10 kW heater going, I might be able to heat Musk’s hot tub and then he might kick in a few million. He’s around here, along with the google boys, Zuckerberg, etc. etc.
        But, not without that 5 to 10kW.

        • Bob Greenyer

          Mats002, the purpose of the post was stimulate debate and I enjoyed the discourse with Axil and others. The real prize was R Little’s contribution.

          I think between them, if there are real things that can be practically done within simple experiments, it would be useful to have them in the roster of planned works.

          In the end, from a user point of view it matters little what the underlying process is – just is it at least as save as a gas boiler.

          A minimum viable product could be a 3kW+ heater for a few hundred $ in retail parts.

    By fuel here I mean whatever is put in the reactor before running it.

    The hypothesis is that Ni62 would perform better as a catalyst than Ni58/60 in the reactor. Maybe the reactor would run better if Ni is all in the form of Ni62.

    My idea is to take the ash of a working reactor, which should be high in Ni62, and mix it with more LAH and maybe more Ni; and use that as fuel in a new reactor.

    I suspect that Rossi realized this after Lugano and has seen major improvement.

    Thanks winbuff67, I get a lot of negative comments. I appreciate your positive response. Life has for me has been a struggle, I am given crumbs, yet what positive I give and contribute with so little resources, people in return dig and dig looking for something negative to throw at me. I have a very positive life and contributions and in return this world looks for something negative. 99% on track, but some keep searching for an error? So sad. Thanks for your encouragement! RBL

    A novel model for the interpretation of the unidentified infrared (UIR)

    bands from interstellar space: deexcitation of Rydberg Matter

    I have been looking for ways to optimize production of Rydberg matter whose generation is discribed by Lief Holmlid in the reference above and except below.

    We now report on a model in

    which all UIR bands are due to electronic deexcitation in the

    condensed phase named Rydberg Matter. This type of very low density

    condensed matter is formed by condensation of Rydberg

    states of almost any type of atom or small molecule, in space

    mainly hydrogen atoms and molecules. The intial formation of

    Rydberg states is due to desorption of alkali atoms from surfaces

    of small particles, especially carbon particles. This desorption

    can be caused by radiation or moderate heat and gives long lived

    circular Rydberg states. Rydberg Matter can be produced

    in macroscopic quantities in the laboratory.

    To meet this method of rydberg matter production using carbon based generation capability as segested about, I looked for a chemical compound that would be superior to (LAH; Lithium tetrahydridoaluminate) that contained Carbon, an Alkali metal. and Hydrogen. I assumed that replacing aluminum with carbom would make a better catalyst for producing Rydberg matter. My search for a replacement led to two alkkali compounds in the same family as follows:

    lithium hydrogen acetylide Li HC2

    potassium hydrogen acetylide KHC2

    See

    https://en.wikipedia.org/wiki/Acetylide

    When these acetylides are heated, hydrogen is released, then the alkali metel is released from the carbon as the temperature rises. After the release of hydrogen, potassium/lithium carbide is formed. Potassium carbide was the active LENR material in the DGT reaction. This stuff was used in miners lanterns to produce illuminating gas when water was added.

    As a disclaimer, I am not a chemist, so I don’t know the toxicity and explosion risks of these compounds. Please help here.

    IMHO, to test the Rydberg matter cause of LENR, a series of tests using one or both of these Acetylide based compounds might be worth a try.
