    Dear Readers:
    Today has been published on the Journal of Nuclear Physics the paper ” Disputable Issue of Matter and Antimatter Simmetry ” by Dr Aleksei Savchenko ( A.A. Bochvar Institute of Inorganic Materials- Moscow, Russia )
    Warm Regards,

  • Andrea Rossi

    Not necessarily.

    Hello Mr Rossi,

    I have a follow-up question about the stackable SKL´s:

    Does your answer mean that you plan to sell E-Cats with Control unit and plain E-Cats without so that they can be easily connected to an already existing control unit?

    Best regards,


  • Andrea Rossi

    Thank you for your insight,
    Warm Regards,

    1. I cannot answer in positive or in negative
    2. same as in 1
    3. The Ecat SKLs can be connected in series and in parallel

    Hello Dr Rossi,

    I am curious about a few totally different aspects of the E-Cat SKL:

    1. Are you using some sort of induction to harness the energy of the SKL´s plasma?
    2. How many power outlets are you planning on the device?
    3. Can you stack the SKL´s? Can you stack SKL´s (95/5 %) to get a power output that accumulates? Let´s say two stacked SKL´s can give a power of 9.5 kwh/h? That would be very nice to power a car at home to keep charging times low…

    Best regards,


  • Dr. Rossi,

    If you are not familiar with the work of Peter Rowlands, his paper makes for an interesting read, “Physical Interpretations of Nilpotent Quantum Mechanics” (https://www.researchgate.net/publication/45911043_Physical_Interpretations_of_Nilpotent_Quantum_Mechanics)

    Rowlands talks about the zitterbewegung as a vacuum effect, and how the zitterbewegung can be taken as an indication that the vacuum is active in defining the fermionic state. Further, he states that the Zitterbewegung describes the switching between dual vector spaces, a kind of gauge invariance based on their acting as carriers of the same information.

    If I understand, in your paper “E-Cat SK and long-range particle interactions” you view me^2/h(bar) as the cutoff frequency for electron vacuum interactions, where h(bar) is spin.

    Rowland considers the 1/2 h(bar)c spin term an expression of the dipolarity of the weak vacuum, and a physical representation of the weak interaction as a link between the fermion and vacuum, or between real space and vacuum space.



    no less fantastic is that Irving Langmuir could have become one of the discoverers of cold fusion 60 years before Martin Fleischmann and Stanley Pons. This became known recently from a private correspondence between Langmuir and Niels Bohr, which was discovered in the archives of the Copenhagen library. These letters discuss Langmuir’s inexplicable experimental results, which he obtained back in 1909 while working at General Electric to develop the technology of atomic hydrogen welding. When creating an electrical discharge between tungsten electrodes, Langmuir discovered excessive heat release. A thorough check of the phenomenon dragged on until 1927. Finally Langmuir decides to publish a result of which he was already confident. However, Niels Bohr discourages him from publishing, since, in his opinion, this result contradicts the law of conservation of energy, and if an article appears, Langmuir will ruin his academic career and reputation.

    Dear Koen,
    Thank you very much for your kind letter where you express your position as a scientist and a person. I fully agree with you and I apologize for my previous remarks, which now seem too harsh to me.
    Your approach: “trying to explain something complicated in a simple way” is similar to my and I always try to follow this rule. Now there are too many unnecessarily complicated mathematicians concepts exist devoid of any physical meaning, which also applies to the theory of relativity, which, oddly enough, despite its some erroneous ideas, does not contradict the theory of the ether – the Universe that filled with the energy. And one can find more simple explanation of these experiments with mass at speed of light. As well as the structure of proton and neutron. Quarcks theory is not only wrong, this theory is just funny.
    But even more I like your civil position to try to make the world better. And although I practically do not know Andrea Rossi, it seems to me that he adheres to the same position. I feel it intuitively.
    Thanks again for your frank and sincere letter.
    Best regards,

    Hello DR Rossi

    Interesting article on
    Space Travel.

    Dr Rossi,
    Do you think it is possible that strong nuclear force has a magnetic origin ?

  • Paul Swanson


    What kinds of loads have you powered with the E-Cat SKL?
    (Light bulbs, motors, fans, cell phone chargers, etc.)



  • Dear Chuck Davis,
    The last Bolshevik revolution got 30,000,000 people killed. The last Chinese Communistic party revolution got 30,000,000 people killed. I guess that is one method of reducing the population.

    John Atkinson:
    Thank you for your kind sustain.
    We are working very, very hard to make it all soon. We are making strong progress, but I still cannot make a date.
    Warm Regards,

  • John atkinson

    I have been a follower of yours and the e-cat for many years now. I would like to thank you for your staying power and determination to get it right.. my question focuses on the questions and answers given to Rick 57. It appears that you have enough partners and that several test have taken place among some of those parters to move forward. The question concerning the % of certification was answered not applicable and that the presentation date is premature. I Can only guess the reason being -completing the long term test first. If this is true, will they both happen fairly close together. Thank you and may the wind be at your back. John

    Dear Aleksei Savchenko,
    First of all, thank you for your correction!
    High speed would be a more appropriate phrase. I do mean speeds at which the mass of the particle increases significantly, and other characteristics are likely to change as well.

    Unfortunately, there are few people who can explain all this comprehensively.
    An example that stunned me when I was ten years old was when my teacher explained relativity as follows: “if you go faster than the light, and you look at a clock that you leave behind, you see it running backwards.” A few years later, another teacher: “If you have two clocks, and one clock you keep still, and the other you make a few revolutions around the globe at a speed approaching the speed of light, you will see that they differ.”
    My parents’ dated encyclopedia in fifteen volumes was about the only resource I could try to learn from, other than what they told us at our school.
    That way you cannot fascinate young people, so that they are no longer interested in this matter at all.
    After that I only became an engineer in electromechanics, because of a fairly good spatial mechanical insight, but in the meantime the realization has grown that real evolution no longer plays at that level, but at the level of biotechnology and particle physics. In my younger years, “quarks” were a revolutionary concept, but they were represented as “spheres of two colors in a larger sphere”. Such representations are a crime against humanity.
    In the meantime, the sponge has shriveled somewhat and it no longer absorbs new knowledge and insights so easily.
    But trying to explain something complicated in a simple way so that the essence of the concept is preserved, and the public can apply this knowledge as a further building block, is still one of my favorites. Especially when I see that engineers are seen as being unimportant in decisions about the future of the world, I think it’s important that we can explain important technical and scientific concepts to economic heavyweights and policymakers.

    Solar panels and wind turbines were fantastic in the 1980s. But with the news from Pons and Fleischman, I sat half a meter from the TV just to get a glimpse. We did not have a VCR. So the news came ….. and went again.

    Today the new generations have access to fantastic resources and sources of information, but I cry when I see their attention diverted.

    Many comments here assume a desire for an electric car as the main application of the E-Cat. Can you imagine how little imagination people have left.
    Growing an entire biotope on the top of a mountain, under a bell jar on the bottom of the sea, in a deep cave under the ground of the desert, I would find a much more interesting application. It would prove that we have attained mastery.

    To avoid wars, violence, death, extermination and disease – as they have always existed – we urgently need a better energy source. The current ones are just to give our generations the time and resources to take the next leap.
    Ten years ago I saw the future of my children very gloomy. And then, Andrea arrived with his E-Cat. Since then there has been hope that part of humanity will survive.

    Kind regards,

  • Chuck Davis

    Dear Eernie1, We are in agreement on overpopulation! Every opportunity I get, I try to make our government understand that we need to reduce the population which unfortunately falls on deaf ears. Recent data shows that pollution has reduced significantly since covid has restricted transportation. But government operates on a basis of greed, higher population = more taxes, they care not about anything else. I fear nothing will change until people revolt.

    Warm regards,
    Chuck Davis

    I hope the Ecat will give a substantial contribution. Surely, if it will work it will not have emissions of sort.
    Warm Regards,

  • Dear Andrea,
    Almost all the warnings about eventual global catastrophic events issued by doomsday prognosticators corresponding on this blog are about global warming. So the main thing they relate your device to is the possible decrease in CO2 it will create, although these events are not in my opinion at this time, very noticeable.
    However what they should really worry about is the effect on global stability by population growth which is a much more visible happening than global warming. We see its effect in the number of third world individuals attempting to flee their country. Also in the unrest and disruption of these countries caused by their governments. Shortages of basic requirements such as food and energy play a big part in the unrest.
    If I am asked what is the most important aspect of your device, I would answer by far, providing the necessary energy to alleviate these shortages and should command more attention than anything else.
    Humanitarian regards.

    @ Koen Vandewalle @ “where the energy comes from: a charged particle that moves at (almost) the speed of light, and thereby taps zero point energy”

    Dear Koen,
    Please, read carefully what you have written above. I respect any unusual point of view, since I myself sin with it. But the particle cannot be accelerated to the speed of light, its mass increases and this is EXPERIMENTALLY proved. And your zero point energy is the same as the Physical Vacuum energy.
    Best regards,

    Carissimo A.R.
    Pensi che una nuova Amministrazione (USA), diversa da quella attuale, possa aiutare
    o influenzare l’ingresso nel mercato del tuo (nostro) ECAT?
    Do you think the nest USA administration will make more for sustainable energy ?

    @ Enea Romagnoli
    Dear Enea,
    Thank you for your interest.
    To your note, please see the last Chapter published in JoNP in July, as well as in future (November) publication.
    Best regaeds,

  • Koen Vandewalle

    @Enea Romagnoli,

    Andrea recently explained where the energy comes from: a charged particle that moves at (almost) the speed of light, and thereby taps zero point energy.
    This concept is a bit counterintuitive because most of us first learned about how matter and particles exist from a non-relativistic approach, and around which the laws of thermodynamics were written by people who needed to master other techniques.

    Please correct me where I am wrong.

    Kind regards,

  • Andrea Rossi

    Enea Romagnoli:
    Thank you for your opinion,

    Dear Andrea
    I think the laws that govern the universe are few and very simple,
    as Heinstein taught us with E = MC2.
    I am sure that even the law that governs the E-Cat SKL, when it will be definitively confirmed, it will have a simple and understandable aspect.
    Otherwise how do you explain that starting from the little amateur for pleasure as I am
    (October 20, 2020 at 3:37 AM)
    up to Aleksei Savchenko very experienced person
    (October 21, 2020 at 2:41 PM)
    and many others, no one has yet correctly interpreted where the energy emitted by E-Cat SKL comes from, as described in your paper

    I think it’s just a matter of time!

  • Andrea Rossi

    Thank you for your insight and your sustain.
    Warm Regards,

  • Brice

    Dear Dr. Rossi,

    The way how I perceive the SKL is that it is a real spectacular device, correct me if I’m wrong:

    *a charge lasts 6 to 12 months continuously
    *needs only a battery for the initial start
    *can be used stand-alone at remote places
    *probably a very long life expectancy
    *can be easily switched on and off
    *95% electricity, 5% heat only
    *generating a mass of energy
    *modifiable energy output
    *compact and flexible
    *no harmful radiation
    *greener than green
    *no EVOs created

    That this is your masterpiece is an understatement. If everything is true, then IMHO you deserve the Nobel Prize in Physics, Chemistry and Economy… And if they don’t owe you this prizes then you deserve at least the Nobel Prize in Literature for the most read scientific publication on ResearchGate ;-).

    I agree with the people who think that you don’t need advertisements and marketing for the SKL. You already have a long waiting list of buyers and once they are convinced of the SKL the big problem will that you can’t keep up with the orders.

    The SKL is everything the world needs now. Notwithstanding that you are a very positive and enthusiastic person, yet I have the feeling that you are still reluctant, for unknown reasons you prefer to postpone an official publication, demonstrations, photos, market introduction… Of course I can be wrong. What do you see as possible obstacles to release preliminary specifications and mass produce the SKL:

    a) reliability
    b) competitors
    c) old enemies
    d) copycats
    e) possible patent issues
    f) sigma-5-test (6-12 months)
    g) fear of failure
    h) being a perfectionist

    All the best for you and your team!

    Donald G. Chandler:
    The definition of energy I proposed must be considered in the context of the observations made during my experiments with the E-Cat and could be wrong, but I think it is not wrong. Your reference is interesting.
