  • Andrea Rossi

    All our time now is dedicated exclusively to the industrialization.
    Warm Regards,

  • Brian

    Dr Andrea Rossi:
    Will you make other public demonstrations before the presentation of the Ecat QX?

  • arjen

    Dear Rossi

    Your role is mostly research and development, it always has, so my guess is, you will be mainly involved in RD also in the future?
    What is your role in the industrialization part of the ecat , in time %?
    A new or existing colleague is leading the industrialization operation? How many FTE are dedicated to this?

    kind regards

  • Greg Leonard

    Dear AR,
    Congratulations on your results – very well deserved. The new Hydrofusion web pages look very convincing. One small typo in the LENR Technology drop down is the omission of a number in ‘Heat, CHP, Power, Ships, Trains > kW/kg’
    Greg leonard

  • Dear Dr Rossi

    Thank you for the demo the other day it is always exciting to see the ecats out and about. Do you have commercial licensees in Australia?

    Thank you

    Hello Dr. Rossi,
    A good friend recently sent me this. He things it’s important and I heartily agree. A thought on what it’s like to be a “scientific explorer”, from the late Ken Shoulders.

    “An Explorer is the human tip of an arrow-like probe into the future where no teachers have gone before. They say explorers are easily recognized as one rides along the frontier in a comfortable Calistoga wagon. Explorers are the ones beside the trail whose face is in the mud and have an arrow in the back. That illusion is not too far from the truth as they are frequently attacked while crossing treacherous territory all alone. For the scientific explorer, attacks most often come from the most benign looking sources—academic institutions. Explorers must be natural, self-motivated leaders and possibly those that cannot be taught, as they must learn new things for themselves instead of being taught. This characteristic alone is basis enough for an attack from the academic camp as it demonstrates nonconformity, an incorrigible act.”

    I amplify the question of Chuck Davis
    The E-Cat QX system formed by the reactor and the control system:
    1) emit electromagnetic noise?
    2) emits neutrons, gamma rays or other particles and radiation of any kind outside the thermal and light band?
    3) Is a sort of shielding necessary, particularly in power systems?
    Best wishes

  • Dear Dr. Rossi,

    Last year you gave the following dimensions for the E-Cat Quark cell:
    November 4, 2016 at 11:35 AM
    Wilson Ramos:
    length 2 cm
    Diam 0.6 cm
    Rating 20 W
    Warm Regards

    This week the QX cell is reported by you to be length 0.6 cm and diameter 0.08 cm.

    Are these cells constructed differently? What is the advantage in reducing the size of the QX cell? Would’t this make assembly very difficult?

    Best of luck with your industrialization process.

    Best Regards,

    Daniel G. Zavela

  • Andrea Rossi

    Yes, we are. With the help of God, by the year 2018 we could enter massively the market.
    Warm Regards,

  • Andrea Rossi

    Chuck Davis:
    The E-Cat does not emit acoustic waves, therefore the E-Cat does not raise the acoustic background where it operates.
    Warm regards,

  • Chuck Davis

    Andrea Rossi,
    Do you have an estimate how much noise is present while the Ecat is operating?
    I ask this because some applications like residential, military, recreational vehicles and airplanes would be satisfied with a quiet power source.
    Chuck Davis

  • Dear Dr Andrea Rossi:
    Today in Paris the world is deciding to go toward new energy sources ant to no more fund traditional sources. Are you ready?

    Dear Andrea,

    You wrote: “We are working also on the measurement of the electricity directly produced in the reactor, but it is not easy. So far we just let it be thermalized.”

    1. Does this mean you have the ability to turn off or minimize the electricity produced in the reactor and somehow transform it to heat?

    2. Is the electricity produced directly by the QX problematic for you, if all you want is heat?

    3. Is the electricity produced directly by the QX responsible for the overheating of the control box?

    Kind regards,

    Frank Acland

  • Italo R.

    Dear Dr. Rossi,
    as it seems that the electrical power generated by the QX goes back to the control box where it is thermalized, the real total COP of the QX is much greater.

    The problem is, I think, to separate this generated electrical power from control box without disturbing the signal feeding the QX. Is it right?

    Kind Regards,
    Italo R.

  • Robert

    Dr Andrea Rossi,
    Do you know that Nissan has replicated your effect and is oriented to apply your technology to heat the electric cars? By the way: is your IP patented also in Japan?

  • Eric Ashworth

    Daniel De Caluwe, As you are aware evolution moves forward, language will change but the immutable knowledge remains forever. Matter is controlled by force and force is that which is not matter. Spirit I believe is an admixture which provides a paradox for that which thinks and tries to discern in order to understand. The Master Koothumi does not mention ‘Time Crystals’ but understands the subject implicitly.
    To understand force is to understand the governor i.e. both the big chief and the little chiefs.
    P.S. This manuscript is news to me, thanks for broadcasting it.

    Dr Rossi,
    Congratulations on successful presentation and rapid advancement of the industrialization phase of your project. As you move forward do not disregard the idea of creating your own cryptocurrency that is based around the LENR reaction.
    Every action in our universe involves the exchange of the energy and as such the energy seems to be the only “real” currency of the universe. Creating a symbolic currency that is tied to your system is much better of an idea (and gives an easy to understand link and value) than current money (both crypto and paper). Why use dollar if your system could be tied to an actual energy value? For the first time ever? Versus Bitcoins, dollars, and euros that are printed out of thin air.

    Well…if the waiting will remain permanent, at least something permanent happened in the History! You wouldn’t mind, I suppose.
    Warm regards,

  • Andrea Rossi

    Koen Vandewalle:
    We are working also on the measurement of the electricity directly produced in the reactor, but it is not easy. So far we just let it be thermalized. About the direct propulsion I suppose you mean jet engine: it is another pet project of us. But presently we are focusing on the massive industrialization of the product that is ready to go, which is the fluid heater.
    About ” temperature formulas of a black body “: do not exist specific formulas for the black body, exists the Boltzmann equation, that measures the thermal energy irradiated from a body independently from what it is. What changes for the different kinds of body is the Epsilon, which is the value of the emissivity that appears in the equation. A black body has Epsilon = 1 and this value does not depend from the nature of the source.
    Warm Regards,

  • Andrea Rossi

    Frank Acland:
    The answer is yes.

    Dear Dr. Rossi,

    I don’t follow this forum contineously, and I only visit it from time to time, but as I just read your post about the super-massive black hole in the early universe, I can give you a link (from the popular website ‘space.com’) with more explanation how it could happen:

    (It’s the mysterious dark matter that steers the cosmos, and that let them grow much quicker than previously thought. The mechanism is explained in the article below):

    2 Bizarre Ancient Galaxies Found in a Colossal Sea of Dark Matter (space.com):


    When the universe was in its infancy, the very first galaxies were tiny “dwarf galaxies” that clumped together to form the larger galaxies seen today. Known as hierarchical formation, this theory suggests that galaxies form in a step-by-step process as smaller galaxies are pulled together by their mutual gravitational attraction.

    But now, the recent discovery of two distant galaxies that are abnormally huge has led astronomers to rethink that theory because it suggests that those dwarf galaxies assembled into large galaxies a lot faster than previously thought.

    Astronomers at the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile were surprised to find that these gigantic galaxies existed when the universe was only 780 million years old, or about 5 percent of its current age of 13.8 billion years. Because the light from those galaxies takes about 13 billion years to reach Earth, astronomers observing those galaxies are looking back in time at how the galaxies appeared 13 billion years ago…

    … Around that same time in the ancient universe, dark matter — a mysterious, invisible form of matter that accounts for about a quarter of the universe’s mass — also began to form clumps. As gravity pulled together clumps of both visible matter and dark matter, galaxies were born inside “halos” of dark matter. In a way, dark matter acts as scaffolding for young galaxies as they form by providing the gravity needed to pull mass together.

    In this case, astronomers saw that both giant galaxies reside inside one even more enormous dark-matter halo. The researchers said that this is one of the largest examples of a dark-matter halo ever discovered…

    …”This discovery provides new details about the emergence of large galaxies and the role that dark matter plays in assembling the most massive structures in the universe.”…

    At het end of the article there’s also a beautiful video that shows/simulates how these galaxies quickly merge by the influence of massive dark matter. But sometimes, smaller galaxies are protected by dark matter, as is explained in this article ( https://www.space.com/6407-galaxies-protected-dark-matter.html ). And as long as we don’t understand it fully, dark matter and dark energy behave as an hidden hand that steers the cosmos, like if it’s a living entity… 😉

    Galaxies Protected by Dark Matter :


    P.S. This phenomenem was predicted by the theosofical master Koothumi in 1881-82, where he wrote of ‘invisible matter’ as ‘invisible omnipresent omnipotent Proteus with its unceasing motion which is its life’ See:


    …Then what do we believe in? Well, we believe in matter alone, in matter as visible nature and matter in its invisibility as the invisible omnipresent omnipotent Proteus with its unceasing motion which is its life, and which nature draws from herself since she is the great whole outside of which nothing can exist. For as [d’Holbach] truly asserts “motion is a manner of existence that flows necessarily out of the essence of matter; that matter moves by its own peculiar energies; that its motion is due to the force which is inherent in itself; that the variety of motion and the phenomena that result proceed from the diversity of the properties of the qualities and of the combinations which are originally found in the primitive matter” of which nature is the assemblage and of which your science knows less than one of our Tibetan Yak-drivers of Kant’s metaphysics….

    Dear Andrea,

    This question came up on E-Cat World and I thought I’d pass it along to you”

    “Would like to ask Dr Rossi if the control box in the demo of 60W cooling is suitable for the control of an array ( series / parallel) of QX of 1kW heat output?”

    Thank you,

    Frank Acland

  • Koen Vandewalle

    Dear Dr Andrea Rossi,

    You know that I always respond as a friend, and admire your work and art.

    Yet some critical remarks that rage through my mind.

    I think that the operation of an Ecat-QX between 30% and 100% of its power is very interesting:
    It is your own words that once declared that this invention generated direct propulsion and direct electric current.
    I would like to see the oscilloscope on the Ecat-QX itself, keep a compass on it, and see the bottom plate with the test set up on four marbles on a flat surface.

    Finally, I do not know whether the temperature formulas of a black body can be applied to a nuclear reactor.

    Curious regards,

  • orsobubu

    Dear Andrea, thank you for the fantastic developments you and your Team showed us in Stockholm.

    To Emilio “Fox” Volpe, I like to remember some years ago, when I asked Andrea more or less the same question, and he answered that, when the huge amount of work for the industrial product will be firmly on track, he will consider to write or co-write some memories, and surely (!!) he will tour the world with conferences and similar well deserved rock-star shows and hologram-televised appearances. I feel that all the material collected in these years should be preserved and organized to enter in science annals and “the social media supporters” too and also the orsobubu will have a role too in the history-telling of this epic fight.

    Situation is way worse in regard to the actual condition of Leonardo Corp. institutional landing page; I fear that not only the super-massive black hole ULAS J 1342+0928 is going back 690 million years in time, but also the dear old twin galaxies image as we remember it:


    is fading and shrinking into the obscurity of the Dark Ages of the Universe where the revolutionary information is hidden:


  • Eric Ashworth

    Dear Andrea, Thank you for your recent reply which prompted me to do some brief study on the Wikipedia web site regarding Systemic systems, Time Crystals and Symmetry regarding physics. As you stated you are seeking a mathematical formulae for the LENR process. In the Time Crystal section there is mention of Experiments October 2016 Christopher Monroe in which a formulae is provided and maybe this could help you in some way. In 2016 Mikhail Lukiu did more research and maybe both your information and theirs could shed some light on the LENR process. In the meantime I wish you and your colleagues well and successful with your technology.
    Best Regards Eric Ashworth

  • Dear Andrea,

    Yes, the big black hole story is interesting. There is a small anecdote related to it. MIT’s press release writes “…the black hole took shape just as the universe was undergoing a fundamental shift, from an opaque environment dominated by neutral hydrogen to one in which the first stars started to blink on.” ‘Opaqueness’ here refers to opaqueness in hydrogen Lyman alpha wavelength, not optical, but the press release does not mention this fact. Consequently, the story was wrongly publicised in some Finnish news outlet, which I corrected to them. In optical, the situation is the reverse because neutral hydrogen is transparent and ionised hydrogen scatters light to some extent.

    Concerning the topic, my colleague Peter Johansson published earlier this year a model that tries to explain such fast growth of black holes. See https://www.eurekalert.org/pub_releases/2017-03/uoh-nme031417.php . The key is that in the early universe, only molecular hydrogen was available to cool compressing gas clouds radiatively. If hydrogen molecules were split into atoms by radiation of another nearby galaxy, a large gas cloud can stay warm while undergoing gravitational collapse, and consequently it may collapse into a large black hole directly. If star formation manages to take place, collapse stops because a “star fluid” has no viscosity (the individual stars move in ballistic trajectories without friction with other stars or interstellar gas). Thus such mechanism can only work in the early universe where the universe did not contain heavier elements, and even then requires special conditions (existence of two nearby galaxies). Which suits in the picture because although they exist, the massive early black holes seem to be rare.

    I just posted the following on the E-catworld website about an hour or so ago. Thought I’d share it with you, and you might get a chuckle out of it.

    A quarky Christmas carole.
    Sung to the tune of “Santa Claus is coming to town.”

    Ya better not pout
    Ya better not cry
    Ya better listen up
    And I’m telling you why
    Cold fusion IS coming to town.

    It runs when you are sleeping,
    It runs when your awake.
    It runs for years on just one charge.
    It’s a quarx for goodness sake!

    Soooooooo…..(repeat chorus)

  • Andrea Rossi

    Dear Readers:
    In an article published on Nature on December 6th ir reported a very important discovery made by the team of the astronomer Eduardo Banados of the Las Campanas Observatory in Chile: they discovered a super-massive black hole, dubbed ULAS J 1342+0928, 800 million times more massive than our sun. The importance of the discovery stays in the fact that it existed only 690 million years after the Big Bang, which means at the very dawn of the formation of the Universe. This timing does not fit with the supposed amount of matter that was ready at that time. This puts in crisis the existing knowledge about the matter. It appears that in the Dark Ages of the Universe revolutionary information is hidden.
    Fascinating, isn’t it?

    The calculation made by means of the spectrometer and the equations of Wien and Boltzmann that I described corresponds either to three QX at 30% circa of their potential rating, or one QX at his full rating.

    Dear Dr Andrea Rossi:
    Thank you for the clear and correct explication of how to calculate a temperature by means of a spectrometer.

  • Matt

    Could you please give some explanation for the fact that your Boltzmann calculation is for the surface area of one QX, but at the demo you said there were three of them inside?

  • Stephen

    Dear Andrea

    You are right. I have yesterday afternoon reviewed that video of the presentation. And between 02:26 and 02:28 where you formally discuss the point it is fully clear there.

    I would say the point regarding the size of the reaction zone was raised to Energy 2.0 as a question to try clarify this point due some misunderstanding about its size being in fractions mm being mentioned by other people elsewhere and being widely quoted as the actual size in the blogs. I’m sorry if that caused unintended confusion.

    I think you clarified the point here in response to that question perfectly. And it makes total sence now too.

    My overwhelming amazement about the E-Cat QX comes from how all these things fit together once they are correctly understood. Especially when some insight pice of the puzzle comes later which fits perfectly It’s remarkable.

    Best Regards

  • Emilio Volpe

    Dear Dr Rossi,
    You have repeatedly said that your IP is in good hands and this is a guarantee for the future of LENR.
    It would also be interesting to have a detailed history of all the work you have done including failed attempts, abandoned roads, interesting ideas and speculations but which not developed for the most varied reasons. In short, a laboratory diary, or a scientific biography that collects and transmits all the work and experience you have done.
    The field of LENR seems very varied and seems to have many different aspects and may have unexpected developments, perhaps for something that you could not investigate today and that perhaps in the future for someone else could be valuable.
    Best wishes for your work and a friendly Merry Christmas
    E. Fox

    Dear Andrea,
    To solve a problem, it typically helps a lot to understand precisely why it is happening before you can come up with a way to mitigate it.
    Do you currently understand exactly why your controller is generating so much heat?

    Dear Andrea,
    thank you for sharing the Stockholm demonstration and “complimenti” for the result.
    I have some question:
    1- Can we assume that when we see the flash light every some of seconds is the only moment when the reactor is active and he rest of the time it is self sustained?
    2- Are the reactor dimensions you comunicated (0.08 x 0.6) the minimum possible to activate the system avoiding the melting of components?
    Best Regards, Giuseppe
