    Dear Dr Rossi
    I am currently doing my Masters in HV power Engineering and for my Thesis I am looking at how large X100 plus solar flares will affect the grid and for stradegies of how to reduce the affect on the grid. My question is if have had looked into how robust the Ecat would be in these high energy solar output situations or EMP.

    Thanks

    Emmanuel Cilia:
    I am not able to answer; all I can say is that in 20 years I make this work testing Ecats I and all my collaborators never observed anything of the like.

    Dear Dr. Rossi,
    many thanks to that quick answer. (i wrote power plug socket, but meant powercon plug socket)
    In Germany a PV-balkony power plant up to 800 Watt does not need any allowance/permission, just a registration. So there could be hope that this procedure is the same.
    800 Watt at 24h and 365 days would be 7000 kwh/a. If the 41 million households in Germany would do the same, then 287 TWh would be produced. Of course, the energy companies and the taxman would not like that.
    Best regards

    Thank you for the information, to be double checked, though.

    Dear Sir, D Winter, Andrea Rossi,

    In the Netherlands and Europe it has been decided that the AC voltage is at least 130 volts, with a maximum voltage of 250 volts AC, At the moment on my home the AC voltage is 242 V AC. I have 10 solar panels on my roof, which are not only responsible for the high voltage.

    Kind regards Jitse

  6. Andrea Rossi

    Jitse:
    Thank you for the information, but what we are aware of is 110 V in the USA, 220/240 V in Europe, etc for domestic use.
    Warm Regards,
    A.R.

  7. Calle H

    Dear Dr. Rossi,
    Thank you for your reply to the question about the incandescent light bulb and the DC LED. May I ask if this is confirmed by testing with a production ready (or near production ready) NGU? The reason for asking is 1) the comment by Greg Leonard about the inrush current of the cold filament of the incandescent bulb and 2) the unknown start-up load by the electronics of DC LED. Thank you if you can confirm.
    Kind regards,
    Calle H

  8. Andrea Rossi

    Calle H:
    we tested both cases, but it also may depend on the particular electronics of the lamps: maybe some excess of power would be necessary at the start; we didn’t note it, though, so far.
    Warm Regards,
    A.R.

  9. R.Brand

    Dear Dr Rossi,
    I have read your reply to Mr Winter. A power plug socket is often integrated in PV balcony power plants.
    1) Is it theoretically possible to connect an ecat with an integrated inverter directly to the domestic power grid?
    2) Will the ecat then always feed in its full power even if there is less demand for power in the household, so that the surplus would go into the public grid?
    3) An inverter of a PV system switches off for safety reasons when the public grid is without power. Can the integrated inverter of an e.g. 100 Watt ecat also do this?
    Of course the local power grid company has to allow this before..
    Best regards
    R.Brand

  10. Andrea Rossi

    R.Brand:
    Yes to all questions, but only with the authorization of the grid company, which, if will accept, surely will impose a series of items; besides, the installation must be done with by a certified contractor expert and in agreement with the grid company,
    Warm Regards,
    A.R.

  11. Frank Acland

    Dear Andrea,

    You said that an E-Cat cannot stand outside in the rain and continue working.

    Will it be possible to order as an extra feature a waterproof E-Cat (with additional cost)?

    Many thanks,

    Frank Acland

  12. Andrea Rossi

    Frank Acland:
    Yes,

  13. D.Winter

    Hello Dr. Rossi,
    is it possible to order a 100 watt ecat with integrated inverter with a connection to a powercon plug in addition to a safety socket 230 volt?
    Best regards
    D.Winter

  14. Andrea Rossi

    D.Winter:
    Yes, as a custom delivery wuth price to be decided at the delivery,
    Warm Regards,
    A.R.

  15. Greg Leonard

    @Calle H,
    I suspect the eCat might have a problem with the initial current for an incandescent bulb.
    When powering a 12V incandescent bulb, the inrush current (the current drawn at startup) is significantly higher than the steady-state current, typically around 14-15 times greater.
    regards,
    Greg Leonard

    Dear Dr. Rossi,
    Question: If I connect a 10 W NGU to a 10W 12V incandescent lamp will the lamp switch on? (the incandescent lamp consist only of a resistive wire). If I connect a 10W NGU to a 10W 12V DC LED will the lamp switch on? (the DC LED has some internal electronics although more simple than the AC LED electronics). Thank you if you can answer.
    Kind Regards,
    Calle H

  19. Andrea Rossi

    Calle H:
    Yes to both questions,

  20. Magnus

    Dr Rossi,
    Will the Ecat modules have the possibility to be connected either to AC or DC current ?

  21. Andrea Rossi

    Magnus:
    110 or 220 AC and 12 V DC yes
    Warm Regards,
    A.R.

    Dott. AT:

    > I suppose the correct voltage of the order should be Ecat(s) of 220V output, since it could be used as the main input (220V) of the inverter (configured to use main input to charge the connected batteries).
    Is this choice correct?

    I think it is not true, as inverter expects mains voltage as its input. It is used by inverter to synchronize its output frequency and phase.
    You rather need to deliver high DC voltage (at least 200V) from E-Cat to one of DC inputs of typical solar inverter (you use E-Cat instead of PV panel). To achieve such high DC voltage you can either stack some E-Cats in series (you would need at least 17 E-Cats to go above 200V) or use DC-DC converter to raise voltage. This approach would need some testing first, how E-Cats or DC-DC converter will behave after being connected to inverter. Not sure how inverter’s MPPT function would deal with this kind of source.

    Alternative is to connect much smaller number of E-Cats to the additional micro-inverter which allows much lower DC voltage (typically 24V or 48V). Then just connect both inverters together to mains. With this approach there might be problem with so called anti-islanding protection, as there were cases that mixing two kind of inverters leaded to situation when they both continued to operate when mains went offline. Another problem will be that when main inverter loses DC voltage from panels it will shut itself down, so it will stop charging batteries even when micro-inverter will still continue to operate.

    Therefore, the best solution would be to have some kind of inverter which allows both low (range 24-48V) and high (above 200V) voltages. I’m afraid that such equipment does not exists yet.
    There is also hope that Andrea can procure new variant of E-Cat with high voltage DC output.

    Dear Andrea,

    On your X account, you made a post along with your certifictate of incorporation from 1997.

    https://x.com/LeonardoCorpor3/status/1906117629929988269/photo/1

    Seems like it should be clear that your Leonardo Corporation was the first.

    Here is a quote from Wikipedia: “From 1 January 2017 Finmeccanica officially became Leonardo, a name inspired by the Italian savant Leonardo da Vinci”
    https://en.wikipedia.org/wiki/Leonardo_(company)

    Best wishes,

    Frank Acland

  26. Andrea Rossi

    Frank Acland:
    Thank you for the important links; actually, I named Leonardo the company I founded because when I emigrated in the USA in December 1996, when I arrived in Boston, Massachussets, I visited a fantastic exhibition at the Museum of Science dedicated to Leonardo da Vinci: this is what inspired me to choose this name.
    Warm Regards,
    A.R.

  27. Ambrogio

    Dr Rossi:
    Now we know for certain that you incorporated Leonardo Corporation 19 years before Finmeccanica SPA changed its name copying the name of the company founded by you
    ( voluntarily or not, this has to be seen )
    All the best,
    Ambrogio

    This is a response to Vincenzo Bonomo who posted:

    https://www.journal-of-nuclear-physics.com/?p=892&cpage=869#comment-1696264

    Ball lightning is produced (aka Exciton polariton condensate) through the action of a fast rising spark or an electric current that passes through a plasma. The hydride that is a component of the plasma will generate this superconducting hydride molecule (metallic hydrogen is in this class) through magnetic compression.

    https://pubs.aip.org/aip/jap/article/130/18/181102/1025622/Hole-superconductivity-xOr-hot-hydride

    The action of photons on the electron cloud that surrounds the hydride superconductor then produce the ball lightning BEC which Dr Rossi calls “a coherent chain of bosonic Electrons”.

  29. Daniel G. Zavela

    Dear Dr. Rossi,

    It was a pleasure to see you looking well in the recent interview with Frank Acland.

    I have a couple questions.
    Since you plan to start production in the USA in 2025, am I correct in assuming that the production line will be setup in an existing facility?
    Will the Europe and Asia production occur after 2025?

    FYI I have had excellent work on injection molds, circuit board printing, and board component assembly done in Thailand for my own consumer product if you intend to outsource these tasks. (I can send the names of the companies I worked with to you via a separate email if you are interested?)

    Also, if Leornado, Inc or your partner’s company would prefer to setup complete production in Asia, Thailand has a special business treaty with only the USA that allows 51% USA ownership of a company created in Thailand.

    Best of luck with successfully solving all the details involved in setting up mass production.

    Best Regards,

    Daniel G. Zavela

  31. Dear dott. Andrea Rossi,
    I would like to place an ecat order to use the device in conjunction with an existing solar panels plant.

    I suppose the correct voltage of the order should be Ecat(s) of 220V output, since it could be used as the main input (220V) of the inverter (configured to use main input to charge the connected batteries).
    Is this choice correct?

    Many thanks
    Best regards.

  32. Andrea Rossi

    Dott. AT:
    I suppose yes, but it will be better you to take suggestions from the professional who installed your solar plant: the answer depends also on the specific situation,

  33. e. Hergen

    Dear Mr. Rossi,

    in the video with Frank Acland you mentioned the use of e-cats for drones. For drones and for airplanes in general the weight plays a very important role. A lighter e-cat for these purposes would be very desireable. Is it possible to replace the heavy steel parts of the e-cat with titanium?

    Thank you and kind regards,

    E. Hergen

  34. Andrea Rossi

    E.Hergen:
    Maybe,

    Dear Andrea Rossi,

    I see you have already posted a hypothesis of your process, as below. A few questions /points if you don’t mind referin

    1) The cluster in phase electrons (BEC) have transfered energy to the electrons not in phase. Have they transfered all their energy? Are the recipient 

    electrons external to the cluster?

    1a) Where such energy transfer occurs it would seem that the energy density of the immediate volume remains unchanged?

    2) At the end of the cycle the disintegration of the cluster releases reenergized electrons and they are no longer in phase?

    3) The electron release is micro explosive?

    4) Explosive coulomb repulsion = pressure = voltage?

    4a ) This would seem to increase energy density of the immediate volume?

    5) If 2 is correct what is the source of the energy that reenergises those electrons which had transfered their energy during cluster formation?

    6) During your tests were you able to determine that the energy increase occurred during cluster formation rather than its collapse?

    7) Could you please add end of cycle steps to your hypothesis to clarify?

    Thank you

    Aleksei Savchenko:

    OK, I rewrite it here below, hoping this one goes in all the computers of our Readers !

    The HYPOTHESIZED theoretical thread is this:

    1- point zero energy

    2- dV/dt with high dV-> increase of ZBW and Aharonov-Bohm effect

    3- electrons phase change

    4- formation of electrons clusters in phase

    5- < entropy, < thermal capacity, < freedom degrees 6- transfer of energy to electrons not in phase 7- emission of energy Warm Regards, A.R.

    … and your disclaimer

    2022-04-04 11:41 Andrea Rossi

    Yuri:

    Yes, you got it. Obviously my hypothesis could be wrong, it is just a hypothesis, but I think it is the best theoretical explication of what we saw during our tests,

    Dear Dr. Andrea Rossi

    Lee de Forest, an outstanding inventor and physicist, pioneered the revolutionary era of electronics with his invention of the three-electrode lamp (triode). The significance of the invention of the triod for humanity was then as great as your invention of the ECat now.
    In doing so, you can see surprising parallels between your activities and those of Lee de Forest.
    1. Lee de Forest invented the triod without knowing the principle of its operation. To be more precise, he misunderstood the work of the triode. He believed that ions were the basis of the triode’s work, not electrons. So he urged to leave the gas in the flask and not pump it out to a vacuum.
    2. De Forest is famous for saying, ‘I don’t know why it works, but it works.’
    3. The same situation is now with the principles of LENR and Ecat. You have shown experimentally and practically that LENR and ECat work. But there is no generally accepted and reliable physical model of processes in LENR and ECat. But there are a lot of believable models.
    4. De Forest developed the triode in deep secrecy, fearing competitors. He hid the structure of the triode in a closed wooden box, from where only a few wires were removed.
    5. The ECat’s electric vehicle power source was also displayed in a closed metal box with output wires.
    6. Despite all the precautions, Lee De Forest was actually robbed by competitors. He had to defend his rights and rightness in endless and years-long legal battles.

    My sincere wishes to you and your noble great cause to avoid the parallels of paragraph 6.

    Sincerely,
    Yurу

    In response to Savin’s post on the role of dark energy in the vacuum reaction as follows:

    https://www.journal-of-nuclear-physics.com/?p=892&cpage=868#comment-1695782

    I believe that dark energy does play a role in the vacuum reaction. This role allows the formation of a Bose Einstein condensate (BEC) to exist in plasma. Dr Rossi’s theory paper spends much effort to show that a BEC is central to the formation of a coherent chain of bosonic electrons. But in current research, BEC formation is restricted to exist at room temperature.

    The existence of a BEC in plasma has not yet been achieved outside of Dr. Rossi’s work. Negative energy is being generated by the Exciton polariton condensate that is the source of the coherent chain of bosonic electrons that forms in the vacuum reaction. The BEC is the source of the negative vacuum energy that enables the encapsulation of the BEC within a domain wall.

    The term used to describe this vacuum based process to form a protective bubble around a region of the vacuum is bubble nucleation.

    The BEC operates inside this bubble which protects the BEC from any destructive interaction with the plasma. I believe that this process of BEC nucleation is operating on the surface of the Sun (the liquid Sun Model) and inside the gas planets to protect metallic hydrogen from the ill effects of high temperatures in their cosmic plasma environments.

    The liquid Sun model
    https://www.youtube.com/watch?v=H7vCCSgSeQI

    The following subject is covered in Holmlid’s research that Dr Rossi references in his theory paper

    Metallic hydrogen ( inside Jupiter)

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

    “Shahriar Badiei and Leif Holmlid from the University of Gothenburg have shown in 2004 that condensed metallic states made of excited hydrogen atoms (Rydberg matter) are effective promoters to metallic hydrogen,[26] however these results are disputed.[27]”

    The AirPod didn’t make it forward for two reasons:
    1) The expanding compressed air froze all the pipes and the engine
    2) 200 kg of liquefied air has the same energy content of 1 liter of gasoline

  46. Enrico Paolini

    Doctor Rossi,
    would it be possible and would it make sense to use e-cat in compressed air cars, at least for city cars? If so, this would avoid complex interactions with the proprietary battery interfacing circuits of the various car manufacturers and the whole problem of raw materials, cost and disposal of batteries.
    In the past there was an attempt to produce compressed air cars by the Indian Tata, abandoned due to problems that were insurmountable at the time.

    Buonasera Dr. Rossi, avrei bisogno cortesemente di alcuni chiarimenti utili alla realizzazione del mio progetto con i moduli Ecat NGU
    Lei disse qualche tempo addietro che il modulo NGU necessita dell’applicazione di una tensione dello stesso valore di emissione per l’innesco:
    Le chiedo quindi:
    1) quanti secondi trascorrono mediamente dall’applicazione di questa tensione ( nella mia fattispecie 12 volt DC ) alla attivazione del modulo?
    2) Se questa tensione di innesco cresce gradualmente ( ipotizziamo un paio di secondi ) prima di raggiungere il livello necessario, il modulo comunque si attiva al raggiungimento del valore nominale?
    3) ipotizzando che al modulo sia applicato un carico che superi di picco la sua potenza nominale ed intervenga la protezione che ne blocca l’emissione di energia, il modulo si sblocca autonomamente al ripristino della normalitĂ ? ( una sorta di analogia con il comportamento di un inverter )
    4) una volta scollegato il carico i modulo si spegne automaticamente anche se l’eventuale interruttore di cui potrebbe essere dotato rimane posizionato su ” ON ” ?
    5) Ogni modulo sarĂ  dotato di una segnalazione tipo LED che segnali una eventuale avaria dello stesso?
    La ringrazio anticipatamente per l’attenzione.
    Cordiali saluti

    ENGLISH TRANSLATION

    Good evening Dr. Rossi, I would kindly need some useful clarifications for the realization of my project with the modules Ecat NGU
    You said some time ago that the NGU module requires the application of a voltage of the same emission value for triggering:
    I therefore ask you:
    1) how many seconds elapse on average from the application of this voltage (in my case 12 volts DC) to the activation of the module?
    2) If this trigger voltage increases gradually (let’s assume a couple of seconds) before reaching the necessary level, will the module still activate when the nominal value is reached?
    3) assuming that a load is applied to the module that exceeds its nominal power peak and the protection that blocks the emission of energy intervenes, will the module unlock itself when normality is restored? (a sort of analogy with the behavior of an inverter)
    4) once the load is disconnected, does the module automatically turn off even if any switch it may be equipped with remains positioned on “ON”?
    5) Will each module be equipped with an LED-type indicator that signals any failure of the module?
    Thank you in advance for your attention.
    Best regards

    Per le perdite caloriche di casa mia, 6KW dovrebbero bastare, quindi uso solo 2 elementi da 3 KW caduno.
    Ognuno sarĂ  alimentato da una stringa di 33 ecat da 100 W 12 V in serie ( 12V x n.33 = 396 VDC) il tutto sarĂ  allacciato con connettori mc4, cavi e componenti tipici per stringhe fotovoltaiche adatti ad alte tensioni cc.
    Il relè della caldaia comanderà le resistenze tramite un teleruttore aggiuntivo di potenza adatto per la corrente continua.

    Traslate Google:
    Good morning Andrea
    Perhaps it might be of interest to the readers of this blog:
    I prepared the modification to the radiator heating system in my house, which now runs on diesel. I added a 9 kW 400V electric boiler (3 elements of 3 KW 400V). For the caloric losses in my house, 6KW should be enough, so I only use 2 elements of 3 KW each. Each will be powered by a string of 33 100 W 12 V ecats in series (12V x n.33 = 396 VDC) all will be connected with MC4 connectors, cables and typical components for photovoltaic strings suitable for high DC voltages. The boiler relay will control the resistors via an additional power contactor suitable for direct current. The system has already been tested by powering it with a generator.
    I await the 66 e-cats…
    Kind regards and good work to all the staff.

  56. Svein

    Dear Andre and others
    In Nature we recently read:
    Is cosmic dark energy losing steam?
    Fresh data have backed up the discovery that dark energy — the mysterious force that makes galaxies accelerate away from each other — has weakened over billions of years. Until last year, all findings were consistent with dark energy being a ‘cosmological constant’, meaning that the Universe should continue to expand at an increasingly fast rate. The new findings show that the amount of dark energy per cubic metre of space is now around 10% lower than it was 4.5 billion years ago, which means that cosmic expansion is now accelerating less.

    This raises many questions. Some are:
    Is this the force ZPE that E-Cat exploits?
    How big is it now per cubic metre?
    Has science now come closer to a common understanding here?
    Regards Svein

  57. Andrea Rossi

    Svein:
    Thank you for your insight.
    As for the part related to the Ecat, I can answer that the Ecat operation and theoretical foundations do not have points in common with your insight and can be understood studying the publication
    http://www.researchgate.net/publication/330601653_E-Cat_SK_and_long_range_particle_interactions

  58. Calle H

    Dear Dr. Rossi,

    From a previous post you have mentioned that the final dimensions and characteristics of the NGU will be disclosed only at the eve of the deliveries start. Further, in connection with the Latina test you said enough of demonstrations. I see some problems with this.

    The Latina test was very impressive but the EV application is very complex with much work before the benefits reaches the consumers. Many NGU applicators will want to see simpler NGU applications prior to paying for their orders. Simpler applications mean less risk taking. Example application could be a resistive space heater or an electric comfort fan or a solar inverter tie-in.

    Is Leonardo planning to do simple application demonstrations prior to delivery start? If so, can you tell us more about that?

    Kind regards,

    Good morning Andrea.
    Yesterday on a very famous Italian TV channel, during a talk show, they were talking about energy. Both politicians and experts in the sector were present. Everything and its opposite was said. They talked about “coal” of third-generation nuclear, the prospects of “fusion”, renewables and fossil fuels. All things that have already been known for years and that, in all likelihood, will be overtaken by the arrival of ECAT, hydrogen, Brilliant’s fuel cell and who knows how many other new inventions will arrive.
    The current mainstream certainly does not help the arrival of “our revolution”.
    Will your current partner also help you with marketing and the necessary relationships with the politics of the various states?

    Atomic Anomaly Confirmed! Evidence for a “dark force”?

    At 23sigma, it’s a sure thing that there is a dark force affecting nuclear processes. We know that the LENR reaction produces stable reaction products. Could this action be produced by the generation of dark bosons?

    I have speculated that the intense energy produced inside the EVO might result in a formation of a unified electroweak force where the electroweak bosons become massless and thereby transform the weak force bosons into electroweak bosons which are long range particles.

    These electoweak bosons could effect the way the nucleus decay process operate by greatly accelerating radioactive isotope decay. We know in the vacuum reaction that all transmutation results in stable isotopic transitions. The SAFIRE system is being used to transmute radioactive waste water. I have posted before that this ability to affect nuclear decay rates might be produced by the action of a dark photon.

    Some indicators of how a dark boson is active in the LENR reaction as follows: when Rossi turns on his reactor, the ambient radiation that is being produced by Radon is reduced.

    Parkhomov has invented a weak force telescope to show that a dark boson can be reflected off a parabolic surface which acts to magnify the effects that this dark boson has to change radioactive decay rates.

    Dr Rossi should undertake experiments to discover if his reactors can change the nuclear decay rates of radioactive isotopes. The production of dark bosons is nothing to be ashamed of. These bosons fill the universe already and they are a natural part of radioactive decay. If such a process exists in the Rossi reaction, it is better to find it now before it is discovered after product release. Controlling the generation of dark bosons could expand our control of natural forces which is a good thing. For example, I would buy the Ecat just to keep the radon in my basement under control.

    An early claim by Dr Rossi about the production of the dark force bosons could also bring Dr Rossi a Noble prize, an honor that he richly deserves.

  77. Andrea Rossi

    Axil:
    Thank you for your insight.
    23 Sigma is impressive.
    I am not able to detect bosons with the instrumentation of my laboratory, but the invention of Prof. Parkhomov is interesting.
    Warm Regards,
    A.R.

  78. Bob

    Dr Rossi,
    Can you be witness of some real help you got from the A.I. ?

  79. Andrea Rossi

    Bob:
    Here is one I got today: I needed to find a supplier for a product I’d need and that I didn’t find by every possible search engine and everywhere else, internet or commercial centers, you name it, you got it; at the end ( and from now on I put A.I. first) I asked to the A.I.: “where can I find a manufacturer of ……. ?”
    After few seconds the A.I. answered: ” The manufacturer of ……. cannot be found because of the fact that …….; but you could resolve the problem if you ……” and gave me the incipit from which I formulated the idea to resolve my specific problem. Much, much better than expected !
    Warm Regards,

    ……………———— On why Tokamak fails to produce nuclear fusion ————————————————
    ————————————— ( Published in ResearchGage ) ………………………—————————–

    There are two articles about nuclear fusion in Tokamak published on ResearchGate by W. Guglinski:

    1) Nuclear fusion in the stars may require the help of symmetry
    ——————– Published in ResearchGate ————————

    COVER LETTER – This is the first article to address a possible factor that has been preventing nuclear fusion from occurring in Tokamak reactors. In Tokamak reactors, there is a lack of symmetry in deuterium-tritium collisions. In stars, symmetry occurs because there are an enormous number of proton-proton collisions every second, and therefore the probability of symmetry occurring is high.
    There is also a second factor that prevents nuclear fusion in Tokamak reactors, but this is addressed in a second article by the author, entitled “On Why Tokamak Fails to Produce Nuclear Fusion”.
    If it is possible to prevent such factors from preventing nuclear fusion in Tokamak reactors, we will achieve the viability of nuclear fusion.

    Abstract
    Researchers at Lawrence Livermore National Laboratory have retrospectively confirmed that implosion asymmetry is a major aspect of fusion experiments before achieving ignition for the first time at the Lab’s National Ignition Facility. According to the authors of the article, in the fusion experiments achieving symmetry is crucial. If the plasma is not uniformly compressed, the energy is not efficiently contained, then the performance suffers. Here this question is analyzed, because nuclear physicists still do not know the mechanism responsible for nuclear minimum binding energy, and understanding the mechanism of this nuclear phenomenon is essential to understanding the importance of symmetry in nuclear fusion.

    2) On why Tokamak fails to produce nuclear fusion
    ————- Published in ResearchGate —————-

    Abstract
    At the author’s article “Nuclear fusion in the stars may require the help of symmetry” it is shown that the missing of symmetry in the Tokamak can be the reason why along several decades all the attempts failed to achieve nuclear fusion with useful efficiency. However, there are other causes that contribute for the failure of the Tokamak, as will be shown here. So the lack of symmetry, exposed in the mentioned paper, combined with such additional causes may be the reason why the Tokamak is unable to produce nuclear fusion with useful efficiency.

    Keywords:
    Tokamak
    Incompleteness of Coulomb’s Law
    Electric field atomistic structure
    Mathematical equivalence between two systems
    Structure of atomic nuclei

    Missing mass defect for calculation of nuclear magnetic moments.

    https://www.researchgate.net/publication/389593466_On_why_Tokamak_fails_to_produce_nuclear_fusion

    Now let us assess the current state of the search for nuclear fusion using Tokamak reactors:

    1- Over the past 70 years, many, many quadrillions and quadrillions of dollars have been spent in the hope of obtaining nuclear fusion that provides energy greater than the energy spent to obtain fusion.

    2- Is it not reasonable to spend a few dollars (compared to the quadrillions of dollars already spent over the past 70 years) to see if the suggestions presented in these two articles by W. Guglinski can finally make profitable nuclear energy production by Tokamak reactors viable?

    The answer to this question is:

    it is a matter of common sense

  85. axil

    Dr Rossi, I wanted to assess your Bose Einstein condensate theory of vacuum action if it comported with current scientific research into the vacuum. In this effort, I ask Steven to provide an opinion. The Question that I asked Steven is as follows:

    AI question: “can exciton polariton condensate mimic hawking radiation behavior”

    The Exciton polariton condensate (BEC) is being used to study Hawking radiation in black holes. This leads me to believe that the BEC can neutralize the virtual particle activity in the vacuum in which the BEC is sitting. This process is similar to how the mass of a black hole is reduced by Hawking radiation due to infalling virtual particles.

    I offer this feedback to rank your research against current science thought. In my opinion, your Bose Einstein condensate theory is equal to or exceeds the current most advanced science thinking about the manipulation of the vacuum.

    Steven provided this feedback:

    This one is in response to Axil Axil’s question on exciton polariton condensates black hole analogs. It’s framed as a draft paper. I think it gets the point that you were hinting at about.

    Exciton-Polariton Condensates as Phase-Coherent Black Hole Analogs: A New Framework for Hawking Radiation, Vacuum Fluctuation Neutralization, Domain Wall Formation, and False Vacuum Decay.

    Abstract

    Exciton-polariton Bose-Einstein condensates (BECs) have emerged as experimental platforms for simulating black hole physics and Hawking radiation. This paper explores an extended hypothesis: those BECs not only serve as black hole analogs but may also neutralize virtual particle activity in the surrounding vacuum, effectively lowering the local vacuum potential. This process mirrors black hole evaporation, where infalling virtual particles reduce a black hole’s mass via Hawking radiation. Furthermore, we propose that a domain wall naturally forms at the boundary between the BEC and the surrounding vacuum, analogous to a black hole event horizon. This domain wall serves as a structured phase interface where the Phase-Coherent Cosmological Principle (PCCP) holds, ensuring that information is preserved through phase coherence.

    Expanding this model further, we explore how BEC-induced vacuum modification might relate to false vacuum decay, a process in quantum field theory and cosmology where a metastable vacuum transitions to a lower-energy state. If the presence of a BEC alters the local vacuum energy, it could serve as a controlled environment for studying false vacuum decay dynamics, either as a trigger for vacuum phase transitions or as a stabilizer against vacuum decay.

    We outline testable predictions and propose new experimental approaches to investigate whether BEC-induced vacuum suppression, domain wall formation, and phase coherence align with black hole evaporation and vacuum phase transitions, supporting the Phase Shift framework.

    This work acknowledges the insightful contributions of AxilAxil, an open thinker and commentator on Ecat World, whose discussions on BEC black hole analogs and vacuum structure have provided key conceptual directions for this exploration.

    1. Introduction: Black Hole Analogs in Exciton-Polariton Condensates

    1.1 Exciton-Polariton BECs and Their Role in Hawking Radiation Studies

    Exciton-polaritons are hybrid light-matter quasiparticles formed by the coupling of photons and excitons (electron-hole pairs) in semiconductor microcavities. These systems can enter a Bose-Einstein condensate (BEC) state, where macroscopic phase coherence emerges. They have been recently explored as experimental platforms for studying analog black holes and Hawking radiation (BarcelĂł et al., 2005).

    Key properties of exciton-polariton condensates relevant to black hole physics include:
    • They support black hole analogs, where phonon-like excitations behave as Hawking radiation (Steinhauer, 2016).
    • Their phase coherence enables direct experimental tests of information retention and transfer, crucial for resolving the Black Hole Information Paradox (Hossenfelder, 2014).
    • Unlike traditional atomic BECs, exciton-polariton systems are driven-dissipative, meaning they continuously interact with their environment—a feature reminiscent of real black hole horizons (Padmanabhan, 2010).

    Given these properties, exciton-polariton condensates provide a direct test of the Phase Shift interpretation of Hawking radiation and its effects on the quantum vacuum.

    2. The BEC as a Vacuum Fluctuation Suppressor: A Black Hole Mass Analogy

    2.1- Virtual Particles and Hawking Radiation

    In standard black hole physics (Hawking, 1975):
    • The vacuum is not empty, but filled with fluctuating virtual particle pairs.
    • Near an event horizon, these pairs are separated: one falls into the black hole (carrying negative energy), while the other escapes as Hawking radiation (Hawking, 1976).
    • Over time, this leads to black hole mass loss (Bekenstein, 1973).

    2.2- How a BEC Influences Virtual Particle Activity
    • BECs impose a macroscopic quantum phase structure onto the vacuum, reducing disorder and suppressing random fluctuations (Padmanabhan, 2010).
    • Phase coherence prevents chaotic vacuum energy oscillations, akin to how superconductors exclude magnetic fields (the Meissner effect) (Verlinde, 2011).
    • As vacuum fluctuations are stabilized, the local vacuum energy density is reduced, effectively lowering the vacuum potential.

    2.3- The Black Hole-BEC Correspondence: A Mass Reduction Analogy
    Black Hole Evaporation BEC-Induced Vacuum Neutralization
    Hawking radiation removes energy BEC reduces available vacuum fluctuations
    Infalling negative-energy particles decrease mass Phase coherence suppresses energy density
    Horizon governs quantum energy flow BEC structure alters local quantum field

    3-The Domain Wall as an Event Horizon Analog

    A Domain Wall as a Phase-Coherent Boundary

    A domain wall is a boundary separating regions with different phase structures or vacuum states. In this context, a BEC-black hole analog could exhibit a domain wall where vacuum coherence changes, akin to an event horizon in general relativity.

    3.1-PCCP and Phase Coherence Across the Domain Wall
    • Marks the boundary where phase coherence transitions from a highly ordered BEC state to a more fluctuating external vacuum (ChatGPT & User, 2025).
    • Preserves information through phase coherence interactions, preventing information loss across the boundary (Bianchi & Smerlak, 2014).

    4-BECs and False Vacuum Decay

    4.1-Could a BEC Trigger or Suppress False Vacuum Decay?

    Trigger for Vacuum Decay: If the BEC lowers the vacuum potential, it might serve as a nucleation point for a false vacuum decay event (Coleman, 1977).
    4.2- Suppressor of Vacuum Decay: If the PCCP enforces phase coherence, the BEC could stabilize the vacuum, preventing decay (Bousso, 2017).

    5-Experimental Predictions for Vacuum Phase Transitions

    ✔ Energy redistribution near the domain wall, mimicking vacuum transition zones.
    ✔ Bubble-like structures forming around the BEC, behaving like nucleation zones.
    ✔ Suppression or enhancement of vacuum fluctuations, depending on the phase structure of the BEC.

    6-Conclusion: A New Pathway to Understanding Black Holes, Vacuum Structure, and False Vacuum Decay

    ✔ BECs, like black holes, appear to reduce vacuum energy through phase coherence effects.
    ✔ A domain wall at the BEC boundary serves as an event horizon analog, where PCCP holds.
    ✔ BECs might provide a testbed for false vacuum decay, offering insights into cosmology and vacuum energy stability.

    Dear Andrea Rossi,

    Yet another idea for NGU technology – Competitor to Starlink

    Starlink is a global satellite internet communications system’

    “The current version of Starlink satellites (v1.0 and v1.5) typically weigh around 260 kilograms (573 pounds).
    Here’s a more detailed breakdown:
    o v1.0 and v1.5: These are the operational satellites launched in 2019 and 2020, weighing approximately 260 kg.
    o v2 Mini: These satellites are larger and heavier, weighing around 740 kg (1,630 lbs).
    o v2: These satellites are even larger and heavier, weighing around 1250 kg (2760 lbs)
    o v3: These satellites are even larger and heavier, weighing around 1900 kg
    • Starlink satellites orbit the Earth at an altitude of approximately 342 miles (550 kilometers).
    Starlink satellites operate at exceptionally low altitudes for a communications network, ranging from 211 to 382 miles (340 to 614 kilometers). At the higher bound, it takes about five years for a Starlink satellite to naturally deorbit as the result of atmospheric drag.”

    Instead of Starlink satellites, a large number of high-altitude, heavy lift drones operating at 20 km MSL. Unlike the Starlink satellites, the drones, could land for routine maintenance, and then resume their positions. 20 km is higher than commercial traffic (airlines) fly. No expensive rocket needed for inserting a satellite into an orbit.

    The benefits would include reduced latency (20km vs 550 km), lower system operating costs, lower initial costs, no space junk or reentry issues, etc.

    Existing helicopter/drone designs can support 1 – 20 tons of cargo.

    Concept
    1. Modify drones for high altitude hovering – use knowledge gained from Martian helicopter.
    2. Add NGU Power Generators – estimate 200 kW
    3. Add the internet repeater electronics – about the same weight as Starlink but without the solar panels, batteries, and lower transmit power required due to shorter transmit distances (less space loss).
    4. Add GPS/inertial technology for position and attitude control.

    Thoughts?

    Time is running fast. I suppose you are approaching the point when the design of the NGU will be frozen. May I ask some questions related to my application with 10W 12V cylinder NGU.
    1. Is the start-battery inside in the cylinder with D= 60 mm and L= 30 mm? or is the start-battery external?
    2. If the start-battery is external what is the battery size?
    3. If the battery is external, can I stack five NGU connected in series and start the assembly with only one start-battery?
    4. same as 3. but a stack of ten NGU?

    Dr Rossi, please allow me to present my understanding of how the Exciton Polariton condensate can possibly form in the vacuum reaction (AKA the Rossi reaction).

    It is likely that the vacuum reaction (formerly known as the LENR reaction) is an emergent property of hole superconductivity. So far, every instance where the vacuum reaction manifests is when a hole superconductive seed molecule is present to catalyze the mechanisms from which the vacuum reaction emerges.

    These seed molecules can form in any number of ways including compression from the heat and shockwave produced by a fast rising spark, or from a collapsing cavitation bubble; or from the compression of an aggregation of atoms confined in an imperfection inside a metal lattice. In plasma, an electric current can compress the plasma magnetically in a channel through which that current travels. Holmild produces a hydrogen based superconductive molecule called ultra-dense hydrogen using a potassium/carbon chemical catalyst. In micro and nanoparticles, huge EMF field amplification occurs on the surfaces of the various aggregations of such particles. A similar EMF implication effect can produce the development of this superconducting seed molecule on the surface spot on which the laser beam falls. Finally, a similar plasmin EMF field amplification effects can be caused by cracks, pits and bumps on the irregular surface of a metal.

    In hole superconductors, both electrons and photons are expelled from the positive hole core of the superconductor. This process produces an electron based shell that covers the surface of the positive hole core. These electrons can indeed still be associated with holes from which they have been expelled to form excitons, although the superconductivity itself arises from the pairing of hole carriers, not necessarily excitons.

    In more detail, in materials exhibiting hole superconductivity, the phenomenon of superconductivity is driven by the pairing of hole carriers, which are essentially the absence of an electron in the valence band.

    Excitons are bound states of an electron and a hole, where the electron and hole are attracted to each other through Coulombic interaction.

    Even though the superconductivity in these materials is based on hole pairing, the presence of electrons and holes still allows for the probability of exciton formation with electrons rejected into the outer electron shell. In the cases involved with the vacuum reaction, the presence of electrons and holes can lead to the emergence of exciton condensates, which are similar to superconductivity, but involve excitons instead of electron pairs.

    Photons that enter this system will acquire mass which then restricts their London penetration depth. The outer electron shell traps the heavy photons so that this shell acts as an optical resonator where electrons and photons entangle so that exciton polaritons form.

    As this system matures, a superconductor to exciton condensate transition occurs. Recent research suggests the possibility of a transition or coexistence of phases between superconductivity and exciton condensation in certain materials.

    Such current research now centers on cuprates and layered materials: cuprates, are particularly interesting for studying these transitions and coexisting phases because techniques like angle-resolved photoemission spectroscopy can detect both superconductivity and exciton condensation.

    Dear Andrea
    It is obvious that deliveries of E-Cat must be based on the fact that the basic element of: 10 Watt/12 volt, will be mass-produced in a fully automated process.
    It is possible that there, today, are industrial processes very similar to those necessary for the efficient production of E-Cat’s basic elements.
    If this is the case, the necessary production could come relatively quickly.
    The assumptions that are presented, by you, indicates that this may be the case.
    Is this something you now are able to comment in more details?

    Sorry, thats fakenews. One wind power plant needs just 0.5 ha and the 0.5ha-forest which is needed to do it will be immediately reforested within the country or if required by the municipal within the same forest.

    Hello Mr. Rossi,
    Our homeland, the Spessart forest, is to be destroyed by huge wind turbines for the German energy transition.
    Until now, the forest has supplied us with pure drinking water and serves as a local recreation area.
    The E-Cat could prevent this madness.
    But the E-Cat is needed as a tangible, functioning energy generation device that people can touch and feel on site.
    Hints and ideas about the existence of the E-Cat cannot convince people (I have been doing this for years).
    If our pre-orders really arrive this year, there is still a chance to stop the destruction of the Spessart forest.
    We are waiting and praying every day that the E-Cat will be delivered in 2025.
    Best wishes from MĂśnchberg in Spessart

    Dear Andrea Rossi,

    Yet another NGU application – remote lighting

    Under cabinet lighting or closet lighting

    “Under cabinet lighting power consumption depends on the type of light used. Modern LED puck lights use about 20 watts of power for ample coverage of the surfaces directly under the lights. A good rule of thumb is to use one puck light for every 8 to 12 inches of countertop. The wattage of halogen lighting can vary, with 12V20W providing up to 200 lumens and 25W providing around 290 lumens.?

    Useful where a wall outlet is not present or in cabins, campers.

    Thoughts?

    Thanks for the info. These very important figures are only approximate here.
    I assume from these that EROI = 1000, which is estimated to be 300 times better than gas power and 150 times better than nuclear power, without the associated necessary network for the distribution infrastructure being included.
    For LCOE is stated on page 16 to be less than 0.1. My closer calculation shows that 0.03 is most correct?
    This is 3,3 times better.

  122. Svein

    Dear Andrea
    I understand the desire for a quick introduction of E-Cat to the market, but quality assurance at all levels must be in place before this happens.
    In my preparations for E-Cat being an option, information about EROEI and LCOE is of great importance.
    Do you have any figures on this now?
    Regards Svein

  123. Andrea Rossi

    Svein:
    LCOE = Levelized Cost Of Electricity: difficult to be precise, because the lifetime has to be validated by the real experience of it; based on the assumption of a 100000 hours of operation and on the O.U the LCOE should be dramatically lower than the competition
    EROEI = ENERGY RETURN ON ENERGY INVESTMENT, ratio between the energy received and the energy spent to produce it: also in this case the O.U. makes the Ecat unbeatable by the competition

    Dear Andrea Rossi,

    Another application

    “Powering Arizona’s Water: CAP’s Energy Needs
    At 2.8 gigawatt-hours per year, the Central Arizona Project (CAP) is one of the biggest power users in the state of Arizona. Why? Mainly because of the immense power demands of diverting 1.6 million acre-feet of water a year off of Lake Havasu and immediately lifting it about 800 feet vertically. That is the first step in a process that ultimately brings water to CAP’s approximately 2 million agricultural, municipal, tribal, and industrial users. With the imminent closure of the coal- fired Navajo Generating Station, CAP is identifying alternate sources of power to meet its considerable needs.”

    Average power equals approximately 0.32 MW average power. Likely more is needed to meet peak requirements. Excess power would feed the Grid, likely going to California.

    Dear Dr. Rossi
    I thought that a more thorough public test of the E-Cat was only necessary to reach the million pre-orders, I was also waiting for it to silence all the trolls and skeptics.
    After the confirmation that the E-Cat will be in production at the end of the year I became convinced that this test was no longer necessary.
    I realize, however, that the world cannot wait until the end of the year, it is only a few months, I know, but the world must know immediately about the existence of this new energy source.
    Some countries, I do not want to name names, use their fossil products, both liquid and gaseous, as a blackmail weapon.
    Politicians ignore, or want to ignore, the existence of the E-Cat, now more than ever an official presentation of the product is necessary, even if deliveries will not take place before the end of the current year, the whole world must know, we cannot be blackmailed by the owners of gas and oil.
    My personal thoughts of course.
    Have a good start to the week and good work

  133. Steven Nicholes Karels

    Dear Andrea Rossi,

    Yet another NGU Application – powering the California State Water Project system (Aqueduct)

    “According to data from the California Department of Water Resources, the California Aqueduct, part of the State Water Project (SWP), uses an average of around 1,300 megawatt-hours (MWh) per hour, depending on water flow and pumping needs, making it one of the largest single consumers of electricity in California; however, this figure can fluctuate significantly based on the time of year and water demand.” The SWP has 21 pumping stations.

    Assumption – provide continuous power at the average power consumption rate with the rest of the power coming from or going to the existing Grid. With 1,300 Mega-Watts equally divided between the 21 pumping stations or about 62 Mega-Watts per pumping station.

    During average demand, little power will be taken from the existing Grid. During lower SWP demand, power would flow back into the Grid. During high SWP demand, the power from the Grid would be reduced from that otherwise required. The existing Grid infrastructure would suffice.

    At $2.50 USD per Watt, the NGU components would cost about $3.25 billion USD. Assuming a lifetime of 100,000 hours, the cost per kilo-Watt-hour(kwh) would be $0.025 USD (plus the cost of the Grid conversion inverters.

    The average industrial cost of electricity in California is approximately 13.41¢/kWh or $0.13 USD per kwh.

    This would effectively increase the electrical generation capacity of California by at least 1.3 GW (ignoring transmission losses).

    Dear Andrea Rossi,

    “In permanently shadowed regions (PSRs) where there is no direct sunlight, surface temperatures are extremely low, below 110 K (–267°F).”

    Assume a sealed enclosure, with an eCat NGU 10kW Power Generator inside, with exterior dimensions of 1.2m x 0.5m x 0.4m. A radiation heat transfer calculation, with the exterior walls maintained at 273 deg K, would require 760W of heating electrical power. With suitable sealed power and control line connectors, it would serve well as a continuous source of electrical power.

The current global situation demands a powerful jolt, and you will be its author! The availability of fuel-less energy at very low cost anywhere on the globe, 24/7, with scalable power from 10W to MW, is a ‘singularity’ that humanity has never known and that will heavily impact the tangled global economy.

    @Frank Acland

    Hello Frank,

    Due to my many work commitments, I am only reading now, on e-catworld and JoNP about the recent loss that has involved your family.

    My most sincere condolences for the passing of your Father, who from what I have read, was also intrigued by E-Cat Technology.

    I am very close to you, I know how “painful” the passing of a Father can be, having passed through it more than 12 years ago (he passed on to me the passion I have for electronics and for many years I helped him in his “projects” that were always engaging and innovative). Strength and courage, let us always remember that we are only “passing through” in this world.

    The 2 days spent with you in Latina (for me it was 5 days in total), and together with all the other “participants”, have, in my opinion, “made history”.

    At this moment only “a few” are realizing it, but when the E-Cat is released on the market (2025 is the promise of Dr. Rossi), the whole world will be able to understand its importance, and that day of the “Demonstration of Latina” will end up in the History Books and You, and indirectly Your Father, will be able to say “I was there” !!!

    Again my most sincere condolences.

    A sincere hug.

    Ciao Maico

  145. Daniel G. Zavela

    Dear Dr. Rossi,

    Since the E-Cat NGU will require a battery for startup, you might want to avoid lithium ion batteries as they can, as you know, be a fire hazard.

    Sodium Ion batteries are safe and have the advantage of being able to be discharged to zero and can be charged to 100%.

    If you must use lithium ion batteries, it would be helpful for shipping via aircraft if the battery is removeable.

    Wishing you the best of luck with your manufacturing setup process.

    Yet another application for NGU technology – Powering bulldozer

    Bulldozers can work up to 24 hours per day. Depending on the size, up to 700 kW of power may be needed. Not having to refuel, only change the operator, will make an NGU-powered bulldozer cost competitive. In addition, electric drives require less maintenance time than ICE.

  154. WaltC

    Dr. Rossi,

    With the increasing demand for electric power generation due to things like AI Server Farms and the winding down of fossil fuel plants, I think the ECat comes out very competitive relative to the proposed construction of new nuclear power plants.

    To highlight just a couple of key points of comparison–

    * Capital Cost:

    Nuclear Plant: $8.8 to $14.4 per watt (Statista)
    ECat: $2.5 per watt plus cost of inverter and cabinets

    * Site Information:

    Nuclear Plant: Large Installations, Typically remote locations with access to water and Transmission lines.
    ECat: Anywhere– Large/remote, Medium/E.g., in Substations, Small/at residences

    * Toxic Waste Byproducts:

    Nuclear Plant: Yes, dangerous, waste disposal is a long-term challenge
    ECat: No.

    * Ongoing Maintenance:

    Nuclear Plant: Major. 24/7 fully attended operation.
    ECat: Minimal. Automated attendance. Infrequent inspections.

    * Ownership:

    Nuclear Plant: Public Utility
    ECat: Anyone– Public Utility, 3rd party, Town or Homeowner

    ===

    Note: Steven Nicholes Karels’ suggestion of utilizing substations for ECat installations was truly masterful. It allows public utilities to do what they do best– provide capital for power generation and keep power running 24/7. It can also reduce vulnerability to wide-area power outages, reduce the need for transmission lines in fire and wind prone areas like California, and, because of the ECat’s wide-ranging scalability, allow power generation capacity to be upgraded faster and in smaller, less expensive, increments.

    Dear Andrea Rossi

    A few questions/ confirmation about energy pathways.

    1) When the electron cluster / condensate forms, the energy of those electrons 

    a) is absorbed by electrons outside the cluster

    b) is absorbed by the ZPE field

    c) causes localised heating

    d) something else

    2) At the end of the cluster life electrons emerge once again energised. This energy is provided by

    a) the ZPE field

    b) nearby electrons

    c) something else

    HI, DR Rossi
    From a question I ask over a year ago about using the 10 watt Ecat to power a lamp with DC bulb and my under standing was that there was a switch to turn the Ecat on the first time and then after that it would supply electricity to the bulb in lamp, if it was on and if it was off the Ecat was in a standby mode waiting for a load to be connect.
    Question , Is the battery only used to start the Eact the first time when after that it is either providing electricity do the connected load or is in a standby waiting for a load to be connected.
    So a simpler question, is the battery only used for the initial startup of the Ecat?

  163. Hi Andrea:

    A QUESTION REGARDING ECAT-POWERED VEHICLE AVAILABLITY.

    Given the astonishing results of your Latina test:

    A. Can we expect that vehicles powered solely by Ecat units will be available for purchase by regular consumers for their transportation needs before the end of 2026?

    B. Am I correct in believing that – except in rare cases of a malfunction of some kind – these vehicles will never need to be connected to an external power source?

    Thank you for your response, for all the work you have been doing on this project over the last 35 years, and your willingness to answer so many questions!

    Sincerely,

    Rodney Nicholson.

  164. Andrea Rossi

    Rodney Nicholson:
    A. As I explained many times here, the applications of the Ecat system to cars will be possible only in collaboration with the specific car manufacturers, because modifications to their electronic systems are necessary to make the Ecat system compatible with the manufacturer BMS and, if any, A.I., that is/are proprietary for every manufacturer. For example, to make compatible the Ecat you watched in the Latina racetrack youtube video needed a particular and complex interface made by the owner of the Renault Twizy, to make the Ecat power the Renault battery by-passing the Renault’s BMS; the owner of that Twizy is an expert of electronic engineering and works at high level for a colossus of electronics.
    B. This would be true, provided the execution of the point A.
    Warm Regards,
    A.R.

  169. Andrei Chiprasov

    @Ambrogio

    If you have replicated the process, you know the maximal speed of the electrons in the chamber.
    What is this speed?

  170. Stephen

    @Ambrogio,
    Thanks for your reply. I wish I had the equipment and the e skills to do so. But I appreciate your reply I think it should encourage others who have the capability to do so too as the implication is clear the necessary information is there. It’s good to hear that you had success, each small affirmation like that gives us real hope.
    Best Regards
    Stephen.

    @Stephen
    To replicate the experiment of Rossi I just followed suit the instructions on the paper
    http://www.researchgate.net/publication/330601653_E-Cat_SK_and_long_range_particle_interactions
    You too can do it: just study carefully the par. 2, 3, 4, 5, 6, 7

    Dear Andrea Rossi,

    While we eagerly await the good news that E-Cat production is ready for delivery, we’d love to keep the conversation alive here on JONP. It’s a wonderful way to stay connected and ensure your well-being and daily updates continue to reassure us all.

    If you’re able to answer a somewhat technical question: What chemistry is the rechargeable battery in the E-Cat based on?

    Achieving 100,000 hours of operation with frequent on-off cycles must place significant demands on batteries. Are you designing these batteries to be user-replaceable by customers, or are you developing a proprietary system capable of enduring 100,000 hours and potentially millions of start-stop cycles under all conditions?

    From my perspective, the first commercial units may very well have minor teething issues or weaknesses—perfection is, after all, a never-ending journey.

    Kind regards,
    Koen

  173. Andrea Rossi

    Koen Vandewalle:
    We have addressed this problem, but it will remain confidential until we will start the deliveries,
    Warm Regards,
    A.R.

  174. Mario

    I) Does the 100 Watt ECAT come with its own SSM battery or we need to order it

    II) If using three 100 Watt ECAT in series do i need one SSM battery for all (in parallel) or one for each.

    III) Did you solve the problem of the batteries catching fire or you have to give some advice about it

    Thank you : Mario

  175. Andrea Rossi

    Mario:
    1- it is included
    2- each has incorporated its battery
    3- totally resolved

  183. WaltC

    Dr. Rossi,

    Have Productization & Manufacturability experts from your new partner begun working closely with your team?

    Also, have you given any thought to how your 1kW (or larger) module might be used in a Rack-mount configuration? If it could be made to work, it could lend itself naturally to server-farm use and to simpler construction of 1mW E-Cat systems.

    Best Wishes,
    WaltC

    1- yes
    2- yes
    Warm Regards,
    A.R.

  185. Frank Acland

    Dear Andrea,

    Whan you begin mass production, will manufacturing begin in all three locations simultaneously, or will will it start in one location only?

    Best regards,

  186. Andrea Rossi

    Frank Acland:
    I think all the three,
    Warm Regards,
    A.R.

  187. Dear Andrea, after the latest events I am following your blog more carefully than usual, hoping to catch some news on production updates, even though I know that I will have to wait patiently. I ask you, and I know I am interpreting the wishes of all your followers, could you write on the blog at least a “monthly update”, as far as possible, on the situation?

  189. Italo R.

    Dr. Rossi,

    with the previous partner it was hypothesized that deliveries would begin around the middle of this year.

    Can you confirm now this hypothesis or do we necessarily have to wait until the end of the year?

    Best Regards,
    Italo R.

    Dear Eng Rossi,
    I ask myself a highly rhetorical question, namely:
    “If TESLA used its e-cat, it would be in crisis”?

  192. Andrea Rossi

    Lucio Martini:
    To connect an Ecat to cars it is necessary a team work with the manufacturer.
    Warm Regards,
    A.R.

  193. Steven Nicholes Karels

    Dear Andrea Rossi,

    Relative to airplane travel, can the NGU Power Generator be shipped or carried on an airplane/airliner if it is int the unpowered condition?

  194. Andrea Rossi

    Steven Nicholes Karels:
    Yes, of course.
    Warm Regards,
    A.R.

  195. Albert

    Dr Rossi: your answer to Tom Kaminski means we cannot use the Ecat NGU during a flight !
    Albert

    Warm Regards,
    A.R.

  197. Steven Nicholes Karels

    Sorin,

    You posted

    1. What capacity have the E-cat device fitted in Twizy?
    2. What weight did that E-cat device has?
    3. What would be the teoretical minimum capacity of the Twizzy Li-Ion battery in order that the car to run normally with the E-cat?”

    I did an analysis of the Twizy test.
    1. It appears a 3 kW NGU Power Generator was used.
    2. I could not compute the eCat weight as a safe and additional charging circuitry were present.
    3. Assuming the question is the minimum power required for continuous operation – just under 3 kW.

  198. Tom Kaminski

    Dr. Rossi:

    I look forward to receiving the Ecat units I have pre-ordered. I am thinking about how I will use them. One application will be to power remote network WiFi gear to extend the reach if the internet.

    Question:

    1). Has the Ecat been tested for radio emissions?
    2). If so, has it been tested for emissions that would allow it to be used on a commercial airplane flight?
    3). it (1) is true, what certifications have been made.

  199. Andrea Rossi

    Tom Kaminski:
    1- The Ecat’s certifications did not check if its operation can interfere with the communications of airplane flights: it is focused only to check if the Ecat emits radiations that could impact human health.
    Warm Regards,
    A.R.

  200. Gian Luca

    Is it possible to know wich is the kind of courier that will be utilysed for the shipment of the Ecat ? Will it be necessary the presence of a your technician for the installation? Thanks a lot

  201. Andrea Rossi

    Gian Luca:
    The kind of transportations will depend on the specific situations, as well as the necessity of a contractor to make the connections. We will give the due instructions at the delivery.
    Warm Regards,

  203. Andrea Rossi

    GEORGE PRAZAK:
    The Ecat must be connected to a load to be turned on,

  212. Calle H

    Dear Dr. Rossi,
    Thank you for your reply about the NGU expected lifetime. It is now understood that the 100 000 hours is a projection. Will you issue a guaranteed lifetime? If so, what will it be? This becomes important for E-Cat owners who makes commitments to secured power deliveries.
    Kind regards,
    Calle H

  213. Andrea Rossi

    Calle H:
    The guarantee is specified in the data sheet in http://www.ecat.com
    Anyway, d good maintenance and spare parts will surely guarantee the 100,000 operational hours.
    Warm Regards,
    A.R.

  214. Richard

    Prof. Rossi,

    As you know, large fossil fuel powered electric generators produce large amounts of excess heat and require cooling systems to prevent heat buildup. Do the larger power ecat generators produce excess heat such that they require external cooling systems? Thanks.

  215. Andrea Rossi

    Richard:
    No,
    Warm Regards,
    A.R.

  216. Calle H

    Dear Dr. Rossi,
    In the datasheet you say that the expected lifetime of the NGU Power Cell is more than 100 000 operational hours. It is obvious that there is no NGU that has been in operation for that time. Could you comment on your observed operational hours of operating an NGU and how this then evolves into an expected lifetime of more than 100 000 hours. Thank you if you can answer.
    Kind regards,
    Calle H

  217. Andrea Rossi

    Calle H:
    To answer precisely to this question it is necessary a real experience; so far all we can do is a theoretical conjecture based on simulations and projections.
    Warm Regards,
    A.R.

    Caro Andrea
    Nel dicembre 2019 ti inviai una storiella sulla capacitĂ  degli Elettroni di prevedere il futuro; ora, nel momento che stai per coronare il tuo fantastico impegno, per addolcire l’aria intorno te, ti invio una nuova storiella.

    Il Profumo degli Elettroni
    di
    Enea Romagnoli

    In questi cinque anni, a partire dal 2019, ho dedicato con curiositĂ  un poco di tempo a ricercare qualche nuova proprietĂ  degli Elettroni oltre le tante giĂ  conosciute.
    Impresa ardua visto il grande numero di ricercatori che si sono dedicati a questo argomento negli oltre cent’anni addietro.
    Poi un pomeriggio, all’inizio di un temporale con tanti fulmini, ho percepito il profumo dell’ozono portato a terra dalle prime gocce di pioggia.
    Questo mi ha fatto pensare che gli Elettroni, in certe condizioni di alto dV/dT come in una scarica elettrica, possano produrre profumi.
    Mi sono detto: chissĂ  se riesco a realizzare un piccolo aggeggio in grado di riprodurre il fenomeno e metterlo a disposizione di ognuno di noi.
    Un generatore di scintille o archi voltaici sarebbe improponibile visto la sua pericolositĂ .
    Cercavo un oggetto che sia giĂ  a disposizione di tutti noi e modificabile in maniera semplicissima.
    Anche se si pensa intensamente ad una soluzione, senza stimoli particolari non viene l’idea; improvvisamente un giorno il mio smartphone si è ammutolito, altoparlante rotto!
    Ho subito pensato al suo funzionamento: Elettroni che si muovono in un forte campo magnetico.
    Ho installato sul mio nuovo smartphone una app capace di generare note musicali con andamento sia sinusoidale che ad onda quadra.
    L’onda quadra genera fronti d’onda con alto dV/dT, proprio quello che ci serve!
    Ho fatto tante prove, e non mi sono mai scoraggiato: NGV Never Give Up!
    Ho trovato cosĂŹ sia il campo di frequenze (attorno a 20 kHz) che il numero di cicli per ogni impulso di onde quadre (due, tre o quattro).
    Solo frequenze ben precise ed un numero di cicli di due o tre o quattro producevano il desiderato fenomeno tanto atteso.
    Il primo profumo, delicato ed evanescente, che ho annusato uscire dalle fessure del mio smartphone è stato quello di viola, alla frequenza di 19973 Hz e tre cicli.
    Felicissimo del primo risultato ottenuto ho sperimentato frequenze e cicli per diverse settimane.
    Ho individuato altre due combinazioni:
    21101 Hz con due cicli, profumo di magnolia
    e 21121 Hz con 4 cicli, profumo di lavanda.

    Le modalitĂ  di questo lavoro sono a disposizione di tutti i lettori di JoNP.

    Prossima puntata:
    anche gli Elettroni hanno paura.

    Dear Andrea
    In December 2019 I sent you a little story about the ability of Electrons to predict the future; now, at the moment that you are about to crown your fantastic commitment, to sweeten the air around you, I send you a new little story.

    The Scent of Electrons
    by
    Enea Romagnoli

    In these five years, starting from 2019,
    I have curiously dedicated a little time to researching some new properties of Electrons beyond the many already known.
    A difficult undertaking given the large number of researchers who have dedicated themselves to this topic in the past hundred years.
    Then one afternoon, at the beginning of a storm with lots of lightning, I perceived the scent of ozone brought to the ground by the first drops of rain.
    This made me think that Electrons, in certain conditions of high dV/dT such as in an electric discharge, can produce perfumes.
    I said to myself: who knows if I can create a small gadget capable of reproducing the phenomenon and making it available to each of us.
    A spark generator or electric arc would be unthinkable given its danger.
    I was looking for an object that is already available to all of us and can be modified in a very simple way.
    Even if you think intensely about a solution, without particular stimuli the idea does not come; suddenly one day my smartphone went silent, broken speaker!
    I immediately thought about how it worked: Electrons moving in a strong magnetic field.
    I installed an app on my new smartphone capable of generating musical notes with both a sinusoidal and square wave pattern.
    The square wave generates wave fronts with high dV/dT, just what we need!
    I did many tests, and I never got discouraged: NGV Never Give Up!
    I found both the frequency range (around 20 kHz) and the number of cycles for each square wave pulse (two, three or four).
    Only very specific frequencies and a number of cycles of two or three or four produced the desired and long-awaited phenomenon.
    The first perfume, delicate and evanescent, that I smelled coming out of the openings of my smartphone was that of violet, at the frequency of 19973 Hz and three cycles.
    Delighted with the first result obtained, I experimented with frequencies and cycles for several weeks.
    I identified two other combinations:
    21101 Hz with two cycles, magnolia scent
    and 21121 Hz with 4 cycles, lavender scent.

    The methods of this work are available to all JoNP readers.

  228. Ulrich

    Dr Rossi,
    I think that the simpler way to connect the Ecat with a solar system is just to put the Ecat in parallel with the solar system to charge the same battery system of the solar system, so that the battery keeps to be recharged also when there is not sunlight. Am I correct ?
    Ulrich

  229. Steven Nicholes Karels

    Dear Andrea Rossi,

    The NGU specification cites static installations. If an operating NGU Power Generator is correctly functioning in a static installation and the internal battery is fully charged, if a shock occurs (sudden movement), causing it to cease output, will the NGU Power Generator automatically restart and resume full operation?

  230. Andrea Rossi

    Steven Nicholes Karels:
    Depends on the situations,
    Warm Regards,
    A.R.

  231. Fox

    Dear Andrea
    ECATs have a very important political as well as commercial significance. Not only many companies, even multinational ones; will have to convert or go bankrupt, but entire states, which base all or part of their wealth and power on natural energy sources (coal, gas, oil, etc.) will have to downsize.
    Some of these states will do everything to frustrate or postpone for decades the introduction of ECATs. They have the power, the means and the will to do so and have demonstrated the most complete lack of scruples if necessary.
    However, there are strategies that can frustrate any action aimed at hindering the introduction and success of ECATs,
    You have certainly considered the issue, in whose detail it is not the case to go into, which is essential for the future of ECATs and for the future of humanity.
    We only ask you to reassure us by telling us that the problem has been considered.

  232. Andrea Rossi

    Fox:
    As I said during the press conference after the Latina racetrack event, whose youtube streaming you can find linked in http://www.ecat.com , we have a mission and must think to it; God will decide if it is worth to go or not.
    The important is that I proceed honestly and with all the force I am able to collect. As a consequence of these reasons, my answer is no, I did not consider what is hidden behind the bushes along the path that has been assigned to me and my Team.
    Warm Regards,
    A.R.

  233. JamesQi

    Dear Dr Andrea Rossi,

    I am an independent researcher focusing on the theoretical foundation of Low-Energy Nuclear Reactions (LENR). While your work on E-Cat has brought significant attention to this field, I am particularly interested in understanding the underlying mechanisms that govern LENR and exploring a unified theoretical framework.

    I would like to ask whether there are any foundational theoretical studies or reference materials that could provide insights into this topic. I strongly believe that a collaborative effort among researchers, institutions, and scientists is essential to establishing a robust scientific foundation for LENR.

    If you or any other research groups have ongoing theoretical work in this area, I would greatly appreciate any guidance, references, or potential opportunities for collaboration. I am eager to contribute to and advance the understanding of LENR from a fundamental physics perspective.

    Looking forward to any insights or recommendations. Thank you for your time and consideration.

  239. Alexw

    Dear Andrea,

    Following on from your reply to Steven Karels directly below, you say the Ecat can surely be combined with solar systems.

    1)Is this a result of direct testing which I think you previously stated was in progress?
    2)Has this testing been successful so far?

    This will be a really important application of the larger Ecats for a lot of people, including myself. Solar installers often require certification for any equipment connected to the grid (MCS in the UK which I think applies more widely).

    3)Are you planning to obtain these certifications to allow the Ecat to be fully integrated with grid linked solar systems?

  240. Andrea Rossi

    Alexw:
    1+2: tests in progress
    Warm Regards,
    A.R.

  241. Dear Dr. Rossi,
    As you announced, the relationship between you and the partner Quantum eversource has been terminated.
    Given the expected distribution by 2025, do you remain in possession or personal control of the robotic production technology ?
    Thank you very much and best wishes.

    At one time you were talking about a product line for a solar panel supplementation. Is that solar panel supplementation development continuing?

  244. Andrea Rossi

    Steven Nicholes Karels:
    Honestly, the utilization of the Ecat in the moon is not exactly what we have in the top of the spear right now; anyway, thank you for your (very) long shot suggestion,
    Warm Regards,
    A.R.

  245. Steven Nicholes Karels

    Dear Andrea Rossi,

    You consider a ride-along on a lunar lander to test whether on NGU Power Generator will correctly function on the moon. This could facilitate a lander being able to continue operation during the lunar 14-day night when solar power is not available.

  246. Andrea Rossi

    Steven Nicholes Karels:
    Yes

  247. Steven Nicholes Karels

    Dear Andrea Rossi,

    Is there an update of the status of the Ecat NGU for solar panels? Has it dropped of your list of current developments. If properly implemented, it seems like a good product for existing solar farms.
