Small-scale Nuclear Fusion Could Become a New Source of Energy (University of Gothenburg, Sweden Press Release)

Thanks to David Nygren of the LENR Forum for sharing about the following press release published by the University of Gothenburg in Sweden. The below translation comes from Google with some edits. Link to the original document is here:

Fusion power could soon be used in small power plants. This means environmentally friendly heat and electricity at a low cost of the fuel in water. Both heat generators and generators for electricity can be developed within a few years, based on research that has taken place mainly at the University of Gothenburg.

Nuclear fusion is a process in which atomic nuclei fuse together and release energy. Because of the small atomic nuclei low binding energy can release energy for merging two small nuclei into heavier.

In a collaboration between researchers at the University of Gothenburg and the University of Iceland, a new type of nuclear fusion process is studied. It gives almost no neutrons but instead fast heavy electrons (muons) because it is based on nuclear reactions in the ultra-dense heavy hydrogen (deuterium).

– This is a big advantage compared to other fusion processes that are under development at other research facilities, as the neutrons from such processes can produce dangerous radiation damage, says Leif Holmlid, professor emeritus at the University of Gothenburg.

No radioactive radiation

The new fusion can be used with laser ignition in relatively small fusion reactors with heavy hydrogen (deuterium) as fuel. It has already been shown to produce more energy than is needed to start it. Heavy hydrogen is abundant in ordinary water and are easily recoverable. The dangerous radioactive heavy hydrogen (tritium) which are likely to be required for major future fusion reactors with magnetic confinement thus not needed.

– A great advantage of fast heavy electrons from the new process is that they are charged and therefore can directly give electric energy. The energy of the neutrons produced in large quantities in other types of nuclear fusion are difficult to handle because the neutrons are uncharged. Such neutrons have high energy and are very harmful to living organisms, while the fast heavy electrons is considerably less dangerous.

Neutrons are difficult to slow down or stop, and demand meter-thick reactor containments. Muons, fast heavy electrons, rapidly disintegrates into ordinary electrons and similar particles.

Research shows that much smaller and simpler fusion reactors can be manufactured. The next step is a generator of direct electric energy.

The research in this area has been supported by GU Ventures AB, the holding company at Gothenburg University. The results have recently been published internationally in three scientific journals.

    I was wrong, Ny Teknik have a piece today:

    But the article says a plasma at 50 Million Kelvin makes the fusion, no mention of any thing like LENR here. No dangerous radiation because muons are formed that decay to normal electrons.

    Holmlid and his group have a goal of having a prototype within 3 years.

    • Mats002

      Ny Teknik took away the comment section for this article. Cold fusion was brought up by some commenteers, I think that is why they deleted. The subject has been too infected to handle I think.

  • Mats002

    As usual any claim of fusion without high energy crunching methods as in NIF or ITER is met with silence.

    The minimum delivery for attention seams to be boiling a cup of tea.

    I look forward to see Holmlid serve some prominent person his DD tea, the sooner the better 🙂

  • Axil Axil

    Because there is no gammas detected, it is a LENR reaction.

  • Axil Axil

    Holmlid has seen muons produced inside his reactor when light from fluorescent bulbs in his lab lit the iridium metal that had iron oxide doped with potassium spead on its surface. This type of light has green, blue, and UV wave length components. Fluorescent lights are only 86% efficient in converting UV into visible light. Therefore, this type of light source produces UV. UV is reflected to a maximum extent by iridium. This refection efficiency is the key to plasmonic power generation. In this Holmlid LENR process, The nanoplasmonic reaction is therefore maximized in the UV wave lengths when iridium is used as the substrate metal.

    With this facts in mind, Holmlid does not need a laser to stimulate his reaction, he could just as well use high intensity UV LEDs to produce the UV light that produces the muons. His laser produces green light(532 nm). Otherwise, Holmlid could apply more photon power as input into his reaction by using a UV laser.

  • Alan DeAngelis

    I don’t understand. I thought muon catalyzed d-d fusion had the same branching ratios as hot fusion. I thought it produced a lot of neutrons.

    • Axil Axil

      The fundamental LENR mechanism provides a energy transfer mechanism, a damping process that keeps the nucleus from ejecting subatomic particles. This process is quantum energy teleportation.

  • Herb Gillis

    If this is a main stream breakthrough why are we not seeing it in “Nature”?

    • barty

      And why isn’t this going viral like the press release 1989.. 🙁

    • etburg

      I think that, as with the Lockheed project and some others, people are very cautious. Many people have voiced reservations on the Lockheed project and Lockheed is hardly a fly by night operation. Claims of small scale fusion in any form are met with a lot of skepticism.

    • Axil Axil

      The conversion of light energy to muons is not believable. It cost CERN billions of euros to produce muons in their muon factory. Holmlid could solve all the problems that CERN is having producing “cool” muons. Therefore, LENR production of muons in impossible.


      Like electrons, muons are point particles that produce much cleaner collisions than protons, which would allow Higgs-like particles to be studied with far less background noise than is generated by proton collisions. Being 200 times heavier than electrons, muons lose considerably less energy via synchrotron radiation when travelling in a circular collider and their collisions would produce Higgs bosons in much greater quantities.

      Cool questions

      The big challenge in building a muon collider is how to “cool” the muons so that they can be funnelled into narrow beams that can be accelerated. However, muon-cooling technology is already being investigated at several institutions, including the UK’s Rutherford Appleton Laboratory, while Fermilab in the US has its own dedicated programme to develop a muon collider, which would also allow intense beams of neutrinos to be fired underground at detectors on the other side of the Earth to further understand how neutrinos oscillate between their three flavours.

      One physicist who shares Rubbia’s vision is David Gross from the Kavli Institute for Theoretical Physics in Santa Barbara, US, who shared the 2004 Nobel Prize for Physics for his work on asymptotic freedom. “A muon collider is a great idea,” he told delegates in Lindau, “and one that the US should take the lead on.”

  • Bob Greenyer

    Yes you are right, the work was born out of HolmLids work to make a better target for laser induced fusion – but given that it does not need high temperature – it more than qualifies for the moniker “Cold Fusion”

    • Axil Axil

      I contend that a laser is not necessary, because muons were produced through light stimulation of a fluorescent light.

  • Gerard McEk

    This is indeed very interesting and promissing news! I just wonder how they make this very dense deuterium and very energetic electrons (how much MeV are these electrons)?. Would they willing to show their test facility and explain more in detail how they have done this?

    • Bob Greenyer
      • Gerard McEk

        Thanks Bob, any idea why I can not see Ecco’s comment?

        • Bob Greenyer

          Ecco, a brilliant mind, suffered a little too much burn and did not fail safe. He is taking a time out, unfortunately this has resulted in 1000s of hours of great work being deleted.

          Please see our Facebook.

      • Fyodor

        Bob, is this the type of experiment that MFMP could replicate or is the equipment too expensive and specialized?

        • Bob Greenyer

          It needs to be very well described first before a judgement could be made. Lief is the best place to continue

  • Ged

    As others have pointed out, this sounds way too eerily familiar.

    Be interesting to see if the data provided here can provide more insights into E-cat like reactors and how to build/replicate them. Could be we’re hitting the edges of the phenomenon, while gaining control of heavy hydrogen/deuterium is heading more towards the center.

    One could hypothesize that the “heavy” form is the critical aspect to lead to the fusion, and thus predict that any process that makes heavy H/D could then be used to produce this LENR/Cold Fusion. Question is, what will make heavy H/D? A metal lattice apparently can squeeze H/D into a “heavy” state, given our evidence from the E-Cat and F/P, and other replicators. But it’s fitful, not remotely optimized.

    • GordonDocherty

      As Robert Godes pointed out:

      the radius of a protium-hydrogen atom is 53pm, while the radius for helium is only 31pm, yet hydrogen is absorbed into a crystal lattice, while helium is not, suggesting it is the hydrogen ion that is absorbed, with hydrogen either being more ready to donate its electron to the crystal or, perhaps, allowing the electron to move in closer to the hydrogen nucleus… (fast) heavy electrons close in to hydrogen nuclei sounds a lot like the precursor to ULM formation… or equally black em holes… thus lending further weight to the competing WL and Axil’s black em holes theories, which may not be so far apart after all (as one, the Bose-Einstein condensate of WL, may be the precursor to the other, Axils’ black em holes, or they may, perhaps, form in parallel from electrons collapsing in on protons… just something to mull over…

      • Ged

        All great ideas.

        But, hm, I am not completely sure yet. It seems like we’re still tap-dancing around the truth with incomplete constructs to try to frame the idea. Such is the way of all new discoveries found by observation.

        I don’t think helium fails to enter the crystal lattice due to its size. In fact, it does enter the lattice, but it doesn’t stick, it just moves right through due to its neutral nature. Its diffusion rate is about 65% the speed of hydrogen’s through metal. So, I don’t think the hydrogen atom squeezes just from the diffusion process itself. However, as Edmond Storms hypothesizes, when the hydrogen gets bound into an “active site” and stuck to a section of lattice, it can be “hammer and anvil’d” by simple lattice vibrations.

        This is still an incomplete picture though. We know trying to increase the number of such “active sites” does not in and of itself increase the chance or strength of LENR. In fact, the opposite can happen once the grains are too small or have too much surface roughness with too small of features.

        That being the so far observed case, that suggests the active sites where fusion is occurring are not “hammer and anvil” sites where one hydrogen sits and gets squeezed (consequently, this also changes the main mechanism from hydrogen-nickel fusion to hydrogen-hydrogen or hydrogen-lithium), but instead a larger site that can accommodate a number of hydrogen or hydrogen/lithium atoms together.

        Then, when the lattice constricts, it could be predicted to increase the density of the atoms at these sites, and when vibrating at the right frequency, the resulting super compression waves and short distance particle acceleration could lead to this press release’s mentioned heavy electron production and consequent muon catalyzed fusion. No major radiation, exactly as has been observed.

        In fact, the use of lasers as mentioned in this press release supports the above hypothesis synthesis and predictions. This is because the laser is being used to squeeze a mass of deuterium atoms together in this case, just like a larger lattice bowl site would be doing in a metal like nickel. So, LENR as the E-cat uses could be the exact same method but using metal to compress versus a laser to compress.

        This is still incomplete (no real data in the press release behind why compressing with a laser is doing the job this time versus all other laser compression attempts, and how else they are affecting their fuel), but I think all the theories are starting to coalesce. I don’t think there are “black em holes”, except how atomic nuclei are em shielded by muons.

        Needs a lot more thought.

        • GordonDocherty

          thanks ged – yes, it seems that key to all these effects are larger sites that can be compressed – individual elements coming together, amplifying effects through the growth of standing waves through resonance, at least that’s one way to imagine it – back to the Tacoma Narrows bridge and the wind gusting at just the right frequency to create, then amplify, standing waves… only on a very small scale at a much higher frequency. Again, this points to a much safer mechanism than, say, damped cascading (that can very easily snowball into chain reactions if the damping is insufficient, it fails, or is deliberately engineered to be not there in the first place…)

          • Ged

            I grew up near the Narrows, so that is a particularly powerful image of resonance to me and others in that area. The Mythbusters tested Tesla’s resonance device (small enough to fit into both your hands) on a large bridge, tuned it to the resonance frequency of the bridge, and got the entire structure shaking. Resonance is incredible.

            I agree with all the rest you say too; it is much safer. Now this kicks everything back to the engineers–gotta be some way to design these reactors to maximize those compression states and test the ideas.

            • Axil Axil

              The resonance involved is the dipole oscillations produced on the surface of the rydberg matter nanowire. This voltage produces bark mode SPP solitons at the tips of the nanowire and also at the points of close contract when many hydrogen rydberg matter nanowires aggregate

          • Axil Axil

            Rydberg matter stimulated by UV light produces SPP solitons that then produce muons. Muons then produce fusion reactions in the hydrogen rydberg matter.

        • Axil Axil

          So sorry, please excuse me…You currently have many invalid assumptions in your thinking.

          The hydrogen lays on top of the iron catalyst as rydberg crystals(Iron oxide and potassium). Hydrogen in not absorbed into a lattice.

          Muons cause the fusion and are not a result of fusion.

          The fusion reaction produces fragments of rydberg matter as neutral particles that are given high energies by fusion. No neutrons involved.

          The Holmlid reaction is completely different from the Rossi reaction. It is closer to the Papp reaction where UV produces the reaction.

          Black holes are definitely involved.

          • Ged

            I think you misread my post?

            1. Hydrogen migrates through many metals including iron, as does helium, just very slowly. Still, I was replying to the other poster’s ideas about hydrogen getting squeezed by entering the lattice. The active sites are assumed to be in crevases on the surface, not the interior.

            2. I specifically said “muon catalysed fusion”

            3. Neutron shuttling appears to be involved as the source of the transmutations. I never said it was a cause of fusion, just as the paper states, and no fast neutrons are involved.

            4. I am not so sure about that. There are too many similarities, and a unifying theory is likely involved.

            5. I am utterly unconvinced unless you are using that term in a different way than a quantum singularity.

    • Axil Axil

      I would like to see this experiment repeated with ordinary hydrogen. That should also work.

  • pg

    Hi Mats, would you have any more information about this?
    Thank you!!

    • Mats002

      Since Lewan has not answered this yet, I try an answer.
      Holmlid writes very little in Swedish, I can see no more information in Swedish texts than in the English. Swedish media did not react to this news release at all of what I can see.
      Gothenburg University is one of the absolutely top in Sweden, at least Ny Teknik should pick it up, but the subject must be tabu. That is my conclusion for today.

  • barty

    This is the type of news I want to hear!
    I hope some news sites will cover this.

    This is serious science!

  • John Littlemist

    Google translation “fast tongue electrons” should really be “fast heavy electrons” 🙂

  • Owen Geiger

    Are they researching Rossi’s E-Cat X or developing their own similar reactor? Maybe someone could ask Rossi.

    • pg

      I was wondering the same thing

      • Bob Greenyer

        This is “cold fusion” literally, fusion of a Hydrogen isotope without millions of bulk degrees.

        it is not really the same thing as the Russians would call Cold Nuclear Transmutation.

        It may be enabled by similar processes and it appears that Celani has increased the output of his reactors by leveraging understanding coming out of Holmlid’s work.

    • Axil Axil

      Iridium is not a group ten element so the Holmlid’s reactions are not covered by Rossi;s patent.

  • EmTee

    Is this really possible? As we know fusion is only possible in a big very expensive reactor. The technology will be feasible alway in only 50 years! And please think about the coulomb barrier! Just kidding. 🙂

  • John Littlemist

    Sounds like E-Cat X.
