Leif Holmlid Comments on His Fusion Process

Many thanks to E-Cat World reader Robert H for this translation of a comment made by Leif Holmlid on the Swedish Energykatalysatorn forum here. Below are some excerpts translated from the original Swedish.

No, I research not about cold fusion, I research on laser-induced hot fusion. It enables us to reach a temperature of between 50 and MK 500 MK in the plasma. This one can measure both the neutron energy distributions (published) and from electron energy distributions (to be adopted soon). It is the temperature that needs to be reached to
get the core processes that move with sufficient speed. It might seem strange that this is higher than the established temperature in the solar interior, but it depends on the core processes inside the sun goes very slowly.

My intentions are not crucial for whether our research is correct or not. It is only important what the results are. We have shown in numerous publications that many particles MeV energy emitted from the laser-initiated plasma. This can only be explained simply by the nuclear physics processes such as fusion. More complicated explanations as black holes or the like, we can probably ignore …


The press release we made from the University of Gothenburg and Ny Teknik written about today are based on three scientific articles published. I guess they are difficult to read for those not accustomed to scientific texts. One of them is published in AIP Advances as free readable text, which means that anyone can read and assess. In that article I show the energy output from the laser-induced process is over break-even, i.e. more energy is generated than that supplied with the laser pulse. This is the first measurement of the break-even in this system, and probably ever. Measurements at NIF in the United States, the world’s largest laser facility has not reached that far. A major concern is that many will try to repeat our experiments have so little knowledge in many areas that are important to be able to do independent experiments.


I challenge course that I make things up or that I’m totally nuts. The kind of words do not belong in a
scientific context and falls back on the person who wrote them. Are there no sanctions against such people?

    …”more energy generated than supplied with the laser pulse”. I suppose that he uses a laser with an efficiency of a few percent or less. So it will take a while before a real break-even is reached. I do not think it is a threat for LENR, although I would welcome every new and safe energy source.

    How hard is it to put all this deuterium into the “ultra dense” state that they need?
    Is it cryogenically cooled or does this work at higher temperatures too?

    • Axil Axil

      Can a carbon nanotube be created by cryogenically cooling Carbon? Ultra dense deuterium is a nanowire.

  • Axil Axil

    Holmlid is not thinking logically. First, there is only hot fusion and cold fusion, nothing in between. If he is producing hot fusion, then he would see gamma radiation coming from the impact of high speed neutral particles produced by the copper shield that surrounds the reaction spot. The lack of gamma radiation is a sure sign that the reaction that he is producing is cold fusion.

    Holmlid is a smart guy, it is hard to understand how he could not understand the difference between hot and cold fusion. Could Holmlid be doing the same thing that R. Mills has done, to deny that his research is based on LENR to get people to take him seriously. Does he want to get the scientific community to swallow the hook so that he can reel them in? Once they are flopping around on the dock, he will tell them that they are seeing cold fusion.

      Is it correct to say that the local temperature at the NAE in the moment of transmutations is more than 50 MK?

      • Axil Axil

        This question might be restated as the following: How much power is stored in the SPP, and how much energy is carried in the magnetic beam produced by the SPP.

        There may be instances where a quark gluon soup is produced by that magnetic beam(10^^13 tesla) in the case where a transuranic element is transmuted from many lighter elements,(like in a supernova}. That power level is an equivalent to a temperature in the trillions of degrees range.

    • tlp

      R. Mills research cannot be based on LENR as it was allready started with full theory before F & P press conference.

      • Axil Axil

        R, Mills worked on the Thermocore experiments that show LENR effects. That goes way back. Did Mills abide in LENR way back then, I don’t know.

        • tlp

          Mills did F&P style experiment with Thermacore, but based on his hydrino theory.


          • Axil Axil

            Mills is no dummy. He knew that nobody would take him seriously if the said that his experiments were based on cold fusion experiments. So he invented his own world that many people with money were willing to support. Holmlid might be doing the same thing. We will see.

          • tlp

            Mills hydrino theory is older than F&P cold fusion.

          • Axil Axil

            I am open to correction. If you would be kind enough to show me the description of the experiment that showed the 10 mm light that he called black light and the associated explanation based on the hydrino.

          • tlp


            I think this is the latest submitted paper, not yet published.

          • US_Citizen71

            Clay tablets from Sumeria hold the oldest known religious writings. Does that mean we all should be making sacrifices to Enki?

            Older scientific theories state that the earth is flat and the center of the universe. Should we abandon astronomy and cosmology for these older theories?

            Older doesn’t make something correct.

          • radvar

            Interesting speculation on Enki in Neal Stephenson’s “Snow Crash”.
            Maybe we are already making sacrifices to Enki 🙂

          • GreenWin

            You gotta like the new cosmology where dark energy and dark matter compose 96% of the universe we know nothing about. Don’t think we got it right yet.

            Let’s not PO Enki. He does cool crop circles. 🙂

          • tlp

            Some old theories remains as valid when new theories are invented, but some not. Mills hydrino theory is not an old theory, but new, under 30 years old.

          • Manuel Cruz

            Older in this case means that the researcher could have not plagiarized the works of later researchers, when he first came up with his theory.

          • Axil Axil

            I stand corrected. You are right. Rossi and his new patent now shows that Mills was wrong from the very beginning. He misunderstood what was happening in his experiments. Black Light power will be going out of business soon when Rossi releases his product to the market. It is a binary situation. Either Mills it right or Rossi is right. One will win and one will lose. Such is how these things go.

            I believe that Mills’ suncell is what Holmlid has just demonstrated. They both produce energy when stimulated by light. Holmlid even uses potassium one of Mills’ catalyst elements.

          • Mark Underwood

            Come now Axil, this does not have to be an either or thing. They can both be right. In fact there seems to be a preponderance of evidence that they are both correct.

            Typical hydrino reactions do not yield anything close to the huge energy density of the cold fusion demonstrated at Lugano, where over the course of a month a mere 1 gram of powder produced the energy of what, dozens of gallons of gasoline? On the other hand, Mills newest hydrino technology – the SunCell – is apparently set for huge power densities. So cold fusion has the energy density, hydrino generation has the power density. A win win situation to me. Each technology would have its niche.

            About Holmlid. Isn’t he producing helium, as well as MeV particles? Mills produces neither, so I doubt they are getting energy from the same phenomenon.

          • Axil Axil

            The whispering gallery wave is what the SPP soliton forms.


            Its wavelength that Mills claims to be coming from hydrinos in 10 nn. that wave length is compatible with a SPP soliton with a diameter of 3 nn. That 10 nn wave will fit into a EMF bubble of 10 nn is circumference. In sonalimiesence. a XUV 10 nn light comes from a bubble that is pure water with no Mills catalysts present. DGT said tht the same blue light came from the exploding bubbles that the were see in in their reactor.

            Mills is assuming that black light (10 nn) is coming from an electron orbit that is below ground state because he has seen it in his experiments. He just assums that the XUV can only be produced by chemical based electron behavior.

            That XUV is actually coming from nano black holes or dark mode SPPs.

            Furthermore, In the suncell, Mills is producing the same thing that Holmlid is producing. If fact, they are both getting about the same results. Mills is producing Rydberg matter just like Holmlid is.

            I am not a follower all of Mills experiments, but I will expect that all of them can be explained by SPP theory, even the very low energy ones.

          • Mark Underwood

            Axil, Mills produced all kinds of different wavelengths, depending on the particular hydrino formed. And he has produced all kinds of hydrino compounds, – hydrino hydrides – which sit on shelves at the Blacklight Power building. Does that sound like Rydberg matter? (I don’t think so.)

            The whispering gallery wave concept is interesting, thanks for sharing. Mills has an analogue to that, in that he believes a photon of a particular energy is trapped on the inside edge of a spherical bubble surface- that bubble surface being the electron of the hydrogen atom.

          Excess heat energy was measured at an average level of 24.3 watts ± 6.4 watts. Our
          confidence to report excess heat comes as a result of repeated testing and reevaluation of the test
          procedures and that the shrunken hydrogen molecule has been identified by an independent
          The electron of the hydrogen atom is predicted by Mills to transition to fractional energy
          levels releasing energy when contacting an energy sink resonant with the hydrogen energy
          released. The “ash” of the process is the “shrunken” hydrogen atom called a hydrino.
          Lehigh University (Dr. A. Miller), Bethlehem, PA, using ESCA (Electron Spectroscopy
          for Chemical Analysis)’6′ has found the hydrino molecule absorbed on the surface of nickel
          cathodes used in electrolysis of K2CO3. This work shows a peak near 55 eV which is predicted
          by Mill’s to be the binding energy of the electron for a hydrino molecule. Lehigh’s exhaustive
          evaluations have found no other explanation for this peak.

          • Axil Axil

            So at that time, Mills assumed that the hydrino was a cold fusion mechanism. When did he disown cold fusion?

          • Mark Underwood

            Mills entertained the idea of cold fusion for only a very short time (a couple of years?) after Pons and Fleishmann’s discovery. He thought that hydrinos might be facilitating the alleged fusion. But his own experiments could find no evidence of fusion, only hydrino reactions, so since then he has stubbornly denied cold fusion.

    • Zephir

      /* First, there is only hot fusion and cold fusion, nothing in between */

      Unfortunately isn’t. The cold fusion results from directional low-dimensional collisions of long atom stacks within metal lattice (Fleschmann&Pons, Piantelli), but if we increase the energy, we can achieve similar results even with less oriented atom collisions (LeClair, Holmlid) and occasionally we can simply utilize omni-directional collisions inside the tokamak/NIF plasmas. The transition from cold fusion into hot fusion can be quite seamless instead, as A.Rossi found himself, when he heated his E-Cat reactor way too much.


      Once we don’t collide atoms in linear chains, then the reaction products (neutrons and accelerated electrons) don’t absorb along dense lines of contact, but they escape into an outside unmoderated – and we suddenly have hot fusion from cold fusion.

  • Stephen

    I was just reading an article on Space News about atoms during a supernova:


    It talks about X-ray interactions in Supernova producing an exotic plasma state where the inner electrons are ejected from atoms.

    A supernova its obviously a different environment that that discussed in Leif Holmlid experiment and the article does not talk at all about either cold or hot fusion but I wonder if the high temperatures and energies produced by the lasers might be creating a similar environment on a local scale that has a similar atomic effect that LENR can then maybe take advantage of.

    I could not help wondering if this could play a part in Rydberg matter formation. Also if the inner vacancies from the ejected photons could capture a muon before the outer electrons rearrange and fill these positions.

    I wonder if there could be characteristic photon emission from transitions in muon shell levels similar to those from electrons and at what frequencies these occur. Could these be observed experimentally?

    If characteristic radiation can be seen from muon energy level transitions then it could be interesting to see if radiation of these frequencies occur astronomically, either in supernovae or other energetic shocks and boundaries such as solar flares. Given the muon half life if the radiation occurs well way from known sources such as high in the solar corona rather than just code to the photosphere then it may tell us something about how and where they are formed.

    • Stephen

      If muons are seen do we know if they are positive or negative or do we see both, I suppose in order to form muonic atoms and allow muon catalysed fusion they would need to be negative?

      I suppose even if muons could be generated from some process perhaps involving decay of virtual pions in the nucleus quite a lot of energy would be needed? Would the high temperatures of 50 to 500 MK be sufficient for this?

      Once produced in a nucleus would negative muons wave function naturally move into the available orbital due to overlap with the nucleus or would conservation of momentum require them to be ejected?

      If negative muons are produced from a negative pion in the nucleus I suppose conservation rules would require a Neutron to change to a Proton. If these come from the deuterium this implies it forms He2 + which I suppose would immediately decay to 2 Protons or by beta + decay back to deuterium. Do we see a change in protium/deuterium ratio consistent with this?

      I understand that He is seen. Do we know if this is He3 He4 or both?

  • tlp

    “It is looking really good.”
    said Mills some days ago.

  • Axil Axil

    How those neutral particle fragments that show energy up to 50 MeV without the appearance of gamma radiation in Holmlid reaction is currently a puzzle. A similar behavior seems to be present in the Papp engine reaction and the Suncell by R. Mills.

    The reaction that Holmlid is producing is different in kind than the one that Rossi is producing. Rossi’s reaction is mild in comparison with no apparent high energy particles produced, just heat.

    The process that dictates how the reaction produces energy output may be directed by the mechanism that transfers energy from the site of the nuclear reaction to the final receiver of that energy. In the case of the Holmlid reaction there does not seem to be an immediate thermalization process, but there is thermalization of gamma rays at the very end of all the side effects produced by the Holmlid reaction.

    This last ditch thermalization process may be due to the late onset of a Global Bose Einstein condensate involving SPPs at the very end of the Holmlid reaction.

    Another complication is the production of muons. We know that muons are produced in the Holmlid reaction and possibly also in the Papp reaction. The Papp engine would not work unless extra electrons were produced. These electrons were used to drive the arc that powered the ignition of that engine. These extra Papp electrons might well have come from muon decay.

    More thought and dot connecting is required on this stuff.
