    George Mc Elvenny:
    I didn’t know about the existence of a LENRleaks! This is another sign of the LENR consistency ( he,he,he…).
    I am not informed about what you say. I know that a team of Professors of the Univessity of Bologna has made a reactor after the Lugano test, but I am not informed about their work. Surely they will publish a report when they will have consolidated results, though.
    Warm Regards,

    Hanna Von Goetz:
    No, it is not my merit: it is merit of Dr Alexander Parkhomov, who made a convincing replication and of Dr Irina Uzikova, nuclear Physicist of the Russian Academy of Science, that prepared the ground since when she attended the demo we made with the first 1 mW plant in Bologna on 2011.
    Warm Regards,

    Dear Mr. Rossi:

    I understand in part your response to Mr. Ferro Casagrande but at the same time I
    have the itching sensation that you are pressed by some unmerciful instances to
    attain extraordinary performances from the 103 modules warm E-Cat plant. And all
    that putting yourself in health risk. We think that the domestic unit with COP 6
    is enough and even 3 would be a success if only thermal power is required as is
    the case. And the best of all is that everything is ready for manufacturing.

    Of course, setting in service the E-Cats without proper certification is unlawful
    in US and in EU but we have estimated that more than 10% of the half a million
    preorders come from non USA, non european countries. This yields 5.000 orders,
    some of them of more than a single device. Correct me if I am wrong but
    manufacturing E-Cat for certain countries which allow its installation would be
    perfectly legal. I live in Northern Hemisphere, now summer time, but within some
    months lot of persons shall need thermal energy, an energy that most of them
    cannot pay if generated by wood, natural gas, fueloil or electricity.
    So please, for the sake of mankind (part of it), snap some time to get the
    necessary certifications. Even without further certificates, the safety
    certification (I think it is the more important) was already granted and enough
    for non US-EU countries. Then press the start button of the robotized plant and
    beginn production. Many problems will be solved and you will get in return not
    only a significant amount of money but also the gratitude of so many 3rd world

    Yours sincerely

  5. Andrea Rossi

    We have to respect the laws of the USA and European Countries everywhere we go in the world.
    I confirm what I have already said, also for what concerns the protection of the IP: there cannot be production of richness for everybody if there is not substantial intelklectual property protection. Nobody is going to invest seriously for anything whose iP is not protected.
    Warm Regards,

  6. Andrea Rossi

    Bernie Koppenhofer:
    Basically, yes, with due exceptions to be evaluated in specific situations. IP is easier to protect in 1 MW E-Cats.
    Warm Regards,

  7. Andrea Rossi

    Ing. Michelangelo De Meo:
    In Russia the so called rossi Effect has now been replicated repeatedly, it appears. I think Dr Alexander Parkhomov has a great merit on this.
    Warm Regards,

  8. Andrea Rossi

    Jamews Rovnak:
    Thank you for the update related to the replications on course.
    Warm Regards,

  9. Steven N. Karels

    Dear Andrea Rossi,

    I understand the pressures to get a product to market quickly and the counter pressures of protecting IP and market positioning. You get one chance to do this job correctly in this world of ours. So proceed quickly but carefully. Obtain the necessary certifications and the mass production capability. Have these in hand before you release a commercial product. While people on this site honestly believe that the current prototype unit as is will be usable, you and I know that potential competitors will do whatever they can to prevent an eCat from being commercially successful. While the potential impact of lower energy will greatly affect the developing world, it would be a greater loss if eCat fails on its first release and the technology is lost. In my humble opinion.

  10. Hanna Von Goetz

    Dr Andrea Rossi:
    I saw another replication made by the Russian Academy of Science, that is taking seriously LENR after years of ostracism. Your merit.

  11. Bernie Koppenhofer

    Dr. Rossi: As you know there will be a huge market for your 1 MW E-Cat, how do you plan to protect your IP, will you use the same strategy you are planning for the home 10 KW E-Cat? Thanks again for this site and answering our questions, and thereby keeping LENR discussions in the news.

  12. ing. Michelangelo De Meo

    Hi Dr. Rossi, please read these new experiments that are leading in Russia:

  13. George Mc Elvenny

    Dr Andrea Rossi:
    LENRleaks says that also a team of the University of Bologna has replicated the Rossi Effect with a reactor copied from the Lugano test: is that true?

    Andrea report on MFMP coming out shortly – ash analysis to follow, is my guess!
    “# Robert Greenyer — 2015-07-01 16:41
    Hi David,

    We are investigating the results of the GS3 and post analysis – I hope to publish this tomorrow, but seemingly have a never ending accounting job – including for the MFMP – to do. The analysis has implications for all replications in some way similar to the GS3.

    I am also setting up the Ash analysis.

    We are also helping others to get up to speed with their own replications.”
    I know we both await the ash analysis, although they did not run long enough for much to be there, but any would be very good news for everyone!
    My own guess is that we will see some!


  15. Andrea Rossi

    Giannino Ferro Casagrande:
    For two resons:
    1- to sell an item not safety certified is unlawful
    2- we cannot sell a small unit before we are making massive manufacturing because the risk of reverse engineering is too high. Only a massive production can shield us from reverse engineering, making it not profitable.
    Warm Regards,

  16. Andrea Rossi

    Gretchen Taylor:
    Surely not before the end of the tests on course on the 1 MW E-Cat operating in the factory of the Customer.

    Ma non capisco ! Se io Ti chiedo di vendermi la tua vecchia bici ! Hai bisogno di rilasciarmi un cerrtificato di agibilità !!! Io non credo !!! Sono anni che vivi a contatto con numerosi E-CAT per 15 ore al giorno , e Sei ancora vivo e vegeto . Cosa Ti impedisce di spedire a noi i Tuoi più affezionati lettori un paio di scatolette con dentro questi minuscoli E-CAT . Io Ti leggo da anni !!! Io ,Steven , Gary , Paul , Alexvs , e molti e molti altri Tuoi affezionatissimi lettori e sostenitori .
    Non capisco !!! Giannino di Udin
    Why you cannot sell us one of your prototypes, even if it is not safety certified?

  18. Gretchen Taylor

    Dr Andrea Rossi:
    When will you available for an interview on the status of the art of LENR?

  19. Alexvs

    Dear Mr. Rossi

    Like Mr. Ferro Casagrande and Mr. Karels I am older than you (15 years). Since four years back we all await the advenement of our domestic E-Cats. Whithout wanting to put you in danger with the exhaustive working the 1 MW plant needs, I want to demand you, in my own name and in the name of above mentioned fellows, thorough information about what you have several times promised, i.e. a domestic E-Cat. We do not need 1 MW, just 10 KW. Even 5 KW would be wellcome by me and the group of mates who have booked for it. Not wanting to speak for the whole community we can send you a list of customers who would accept the 5 KW version. Please give us an email address where to send the list.

    We remain yours respectfully

  20. Andrea Rossi

    The R&D and tests that we are making not only with the 1 MW E-Cat, but also with the Hot Cat , are finalized to a massive production. Safety certification and massive production are necessary to fullfill your demand. I can assure you that we are working as much as possible on this issue.
    For what depends on us ( technology) we are very advanced. For what does not depend on us (safety certification) we will gain much time if the tests on the 1 MW plant will be completed with positive results, because the safe operation for 1 year of the 1 MW E-Cat can give a good point of reference also for the domestic applications.
    I really sympathize with you, as well as with Mr Ferro Casagrande, Steven N. Karels and all the many Readers that are sending us comments on the same subject, not to talk of the half million persons that have pre-ordered a domestic E-Cat and that are ready to confirm the order should we deliver our product.
    Warm Regards,

  21. Andrea Rossi

    Gary Underwood:
    Thank you for your attention. I want to underline, though, that the growth has been made together with my great Team.
    Warm Regards,

  22. Andrea Rossi

    Giannino Ferro Casagrande:
    We are making the tests and R&D on course with the plant installed in the factory of the Customer of IH and on the Hot Cat to prepare a massive production (F9).
    Warm Regards,

  23. Paul


    The first aviation e-cat will probably be an unmanned steam rocket with a single hot-cat reactor in a sealed water tank driven to critical failure. I believe you said that the 10 KW hot-cat that failed during the first 3rd party test reached 1MW output over a 10 second period. (We are still hoping to see the video some day.)


  24. Andrea Rossi

    What you write makes sense. I substantially agree.

    Hello Dr. Rossi , I suppose you will be delighted reading this comment.

    From the times of Tesla in the 1890s, Cold fusion has been discovered and then forgotten and then later rediscovered in a tragic cycle of frustration and forgetfulness. Tesla may have been the first. There is a persistent urban legend about Nikola Tesla. The prolific Serbian inventor who claimed that his greatest achievement, the achievement that he was most proud of, was not alternating current or the radio, but a high voltage tube which could produce energy and transmute materials.

    Dear Andrea Rossi,

    Since I am older than you, mostly likely you will win but I will be long gone. My winning solution, experimental aircraft. Plus the battery evolution will push the technology. You do your part for LENR electricity generation and the rest of humanity will do their part – battery and aircraft powerplant development. Keep my bottle of water cold!

  32. Giannino Ferro Casagrande

    Cari Steven ed Andrea , siete molto simpatici sulla disputa di quanti anni ci vogliono ancora per realizzare propulsori LENR su strada o aerei . Io fra 20 anni sarò belle che morto . Ma io caro Andrea aspetto già da molto tempo solamente 4 minuscoli HOT-CAT per scaldare qualcosa in Azienda . Fra quanto me li spedirai ? A me non servono cartacce varie . Vedi se riesci a rispondermi un po meno evasivamente con ad esempio non ho la sfera di cristallo oppure quel continuo F9 di incertezze .
    Rammentate che Vi voglio bene per davvero se non altro perché lavorate non meno di 12 ore al giorno . Ma d’altro canto anch’io ho fatto cosi per più di 40 anni comprese le domeniche e festività . Ciao Andrea ! Forza ! Giannino di Udine !

    Dr Andrea Rossi:
    I read all the more than 23 000 comments and the hundreds of links to the comments in this blog and I am stunned. The amount of information is colossal and what does really stun me is the unbelievable constant upgrading under the scientific, technological point of view that you made in 4 years: it has been an exponential growth. Congratulations and thank you for this dramatic engagement of yours.
    God bless you,

  34. Andrea Rossi

    Steven N. Karels:
    What a stupid man I am!
    I made a statement related to what will happen in future about LENR and Avionics while I didn’t yet receive the crystal ball from Amazon!
    I settle for the water bottle bet, though..but now we have another F9 case: in 2025 Andrea Rossi could be still alive, but also dead…ok, here is the solution: I will put a water bottle in an escrow and you will be entitled to get it, should you win the bet ( you will lose, you will lose…have you the slightest idea of the timespan necessary to get the certifications – I mean safety certifications- for a thing like this in avionics ??? It is taking more than 4 years to make domestic boilres !!!).
    I said 20 years because I am an optimist guy. I cannot forget that the CEO of Volvo, several years ago, told me that to apply LENR to trucks could take about 20 years; can you imagine how much time will be necessary for an aeroplane?
    Warm Regards,

  35. Steven N. Karels

    Dear Andrea Rossi,

    Sorry, but I must strongly disagree with you. I would foresee that LENR will be used for aircraft propulsion within 10 years. The current flight of the Solar Impulse 2 demonstrates that low powered aircraft can be made. Consider using LENR with its long-term fuel and high energy to mass ratio. While I agree that fighter jets that require rapid change in energy output will be the last to see LENR, I would think that slow transport aircraft could meet an economic need as fossil fuels become less available and more restricted. So if there are no LENR powered commercial aircraft in Dec 2025, I will gladly by you a bottle of water.

  36. Andrea Rossi

    Koen Vandewalle:
    I think that the day of aeronautical applications of LENR is not close.
    I think it will take not less than 20 years to see something operating in that field.
    Not less, probably more.
    Warm Regards

  37. Koen Vandewalle

    Dear Andrea,

    Are you confident that major manufacturers of jets will put their wizards to work on LENR ? (So it seems…)

    Kind regards,


  38. Andrea Rossi

    Giuliano Bettini:
    I can say nothing.
    Due information about the performance of the plant will be given after the end of the Tests and R&D on course. The results could be positive or negative, independently from anything anybody could say now.
    Warm Regards,

  39. Andrea Rossi

    Frank Acland:
    The measurements of the efficiency of the 1 MW E-Cat installed in the factory of the Customer of Industrial Heat, obviously, is made with calorimetry, because the plant has to produce steam necessary to the manufacturing process of the Customer. Therefore both the third party that has to certify the performance and the Customer that is using the E-Cat are just measuring the amount of the thermal energy actually delivered from the plant, not the pure heat radiated from the reactors. The measurement of the pure heat radiated from the reactor makes sense in laboratory tests, because, being a direct measurement, not mediated by a heat exchanger, gives more rigorous results.
    For what concerns the Hot Cat we are making tests with inside the computers container, we are making both calorimetric and IR measurements, obtaining similar results, even if calorimetric measurements are lower due to the fact that the heat exchanger makes a loss of energy depending on its efficiency factor.
    I cannot add other information regarding this issue, because all the publishable data will be published when the tests on course will have been completed.
    Warm Regards,

  40. Giuliano Bettini

    Dear Andrea,
    in the last days Aftenposten in Norway wrote:

    “…a source with heavy scientific background in relevant subjects has even been present and able to inspect the container. The reason that he does not want to be named, is that it is considered very dangerous for his career to embrace the highly controversial phenomenon of cold fusion…”
    Without entering in details, IP protection, F9, bla bla etc. may you say:
    who was this guy?
    you were there?
    and whatever you can say (nothing I presume).
    Kind regards
    Giuliano Bettini.

    Dear Dr. Rossi,
    I have read a “Comment” to the Lugano Report ( LR ) that is falsely dressed as a “Article”.
    I will not provide here any reference about the author or the title because I don’t want to give to this kind of criminal any kind of publicity. I call him a criminal because he does a real crime creating false information.
    Just some points:
    All the writing appears to be done by copying and pasting old false argumentation against the LR, the calculation of emissivity is completely wrong, and shows a complete ignorance of the topic by the author.
    The author has not even read carefully the report in which is explained how the ridges emissivity is handled, using only the bare cylinder surface for IR emission measurement.
    The calculation of the power by the author is also completely wrong and purposely misleading not taking in account the power emitted by the alumina pipes ( where the emissivity was measured ! ) and wires.
    The author does not take in account any fact that has been noticed during this almost one year long period after the LR has been published .
    For example that the wires are of a special type of Kantall and most important the replications by four independent groups: two Russian laboratories, one Chinese and one American.
    I stop here for the moment, because I’m to disgusted by this kind of criminals.
    But if necessary I can give more details. But I think that for real scientist this is not necessary.

  45. Andrea Rossi

    Thank you for your insight. I totally agree with you. The concept of epsilon is not easy to undertand for non experts and we have non experts of the field that criticize the measurements of Professors that teach in the universities that specific matter. just like cts that want to teach to miew to cats. About cats: I invite to look the delicious link sent us from our Reader KD two hours ago!

    You are continuing ( also today June 28) to send theories and I am continuing to spam them. Guess why.
    I appreciate your enthusiasm and your kindness, but I cannot give room to theoretical nonsenses, nor I have time to object to them.
    About the replications you are giving us the updates of: to have a precise opinion, it is necessary to receive scientific and detailed reports, with all the data concerning the description of the measurement instruments, a detailed lay out of the measuring system, the graphs of the data.

    Steven N. Karels:
    The R&D on the E-Cat is a neverending process, and this principle is valid for all the parts of our reactors.
    This said, I cannot enter in particulars, because we have to defend out intellectual property. Innovation without IP does not produce global richness.
    Warm Regards,

  49. Steven N. Karels

    Dear Andrea Rossi,

    Is the fuel mixture you are currently using substantially different or improved since the testing you conducted prior to the Lugano test report?

  50. Weleda Sutherland

    Dr Andrea Rossi:
    Thank you for what you said about ” they who have not solid bases better let alone theories”.
    While your titanic work if giving credibility to LENR, the publication of a stream of theories that violate the basic laws of physics gives fuel to LENR opposition.
    Thank you for what you are doing, Andrea.
    Thank you for your exhausting and stressing work.

  51. eernie1

    Dear Andrea,
    I was under the assumption that you mentioned a more refined paper containing a more detailed body of theory was being prepared for publication to be submitted to another main line publication and is under review by your personal physics experts. It was to be submitted when the rough spots are removed.
    Hopeful regards.

  52. Andrea Rossi

    It is in preparation, but it is immature: too immature to know if it will be published.
    Warm Regards,

  53. eernie1

    Dear Andrea,
    It seems to me that you and your co-author of the pre- print of your paper on the theory of the E-cat, are cooking up a theory for the manufacturing of 4He. The alpha particles at the temperature you run your device would easily find the necessary electrons to form the He. Have you measured the amount of He being produced and if so does it correspond to the theoretical amount required? It also seems to me a way to falsify or confirm your theory. The pre-print, IMHO is more of a dissertation on Cook’s lattice theory than on the theory of the E-cat mechanism and then presenting a side issue dealing with its application to your device. The production of two alpha particles by proton capture had been proposed previously in a number of blogs without a firm mechanism to explain it.
    I think that because of the multiple possibilities involved with the nuclear process in your device that only extensive ash analysis including gas measurements can really solve the problem. You must have performed many assays since you have much fuel residue produced by long time operation of both hot and cool devices and the cost of doing the analysis is trivial compared to the engineering costs you are spending on the ongoing tests. I understand the necessity for your not revealing any of the results of the assays, but because of this knowledge and the cooperation with Cook on the paper, I must conclude that the production process indicated must be well indicated.
    Any information you can reveal will be eagerly awaited since it can lead to new scientific knowledge usable to form more advanced engineering devices for mankind.
    Anxious regards.

  54. Andrea Rossi

    The Cook Rossi paper has already been published.
    About future papers, I’d need the mostly cited crystal ball.
    Engineering of advanced applications of the so called Rossi Effect will rise from an Intellectual Property about which we’ll maintain the confidentiality, until a massive production will have been put on the market.
    Warm Regards,

    Frank Acland:
    Good question, impossible answer: to explain what has been the source of important factors emerged from the Lugano Report I should have to disclose confidential particulars. The huge work we made in our lab before the Lugano Report is the base that allowed us to see in the Report what can be observed only if you have “eyes” for it, trained by the huge background I mentioned.

    Dear Andrea Rossi,

    “Cannot stay away” from your eCat is a sign of two possibilities:

    a. Compulsion, based on fear or anxiety or
    b. Great love for the technology

    Condition a is very damaging and unhealthy. Condition b is very healthy and wonderful. I hope it is condition b.

  63. Steven N. Karels

    Dear Andrea Rossi,

    eCat fuel exhaustion is an interesting topic. Do you expect to detect near fuel exhaustion by:

    1. monitoring your control levels or signals and observing a long term, significant increase in demand for the same thermal output level?
    2. The thermal output power gradually begins to decline?
    3. The thermal output power suddenly drops without the ability to recover?
    4. Rapid changes in the thermal output power?

  64. Frank Acland

    Dear Andrea,

    Can you explain why the Lugano report has been so helpful to you, after you have done so many years of R&D of your own? I would have thought you would have made tremendous amounts of measurements of every kind in your own labs.

    Many thanks,

    Frank Acland

  65. Gherardo

    Dott. Rossi,
    from the photos I see here you are too slim for the team !!! :-D
    Don’t be possessive, let them chase the cat too and burn some fat…

    PS: I’m obviously joking, I hope you and your team are in a good mood :-)

  66. Andrea Rossi

    As a matter of fact, I am continuing to lose weight, but I made blood and urine analysis very complete, including cancer indicators and the results are totally good, so I am healthy. The Team is working with me and , honestly, they would be glad to allow me to work the regular 8 hours per day instead of the 16 I work through, but it is me that is not able to stay away from Her. Observing the E-Cat at work, combined with the data of the Lugano Report and the study of the theory of Norman Cook our technology is consolidating by the day.
    This said, I must say F9 ( F9= ” the final results can be either positive or negative “).
    Warm Regards,

  67. McEk

    Steve Karels,
    I certainly do not want to run the Hot cat in an ‘open loop situation’ because in that case you would have no control. As far as I know is the Hot cat controlled by a temperature control loop: If the temperature exceeds a desired temperature, you switch the internal electrical heating element off, if it drops say ten degrees below that, you switch it on. What I understood is that if the temperature increases, the probability of runaway is higher. What I suggested is to control the Hot cat temperature with the flow of the cooling medium (say water). So if the temperature rises you increase the flow, it it drops you lower the flow, so it is still controlled and certainly not ‘open loop’. If, for whatever reason, the temperature continues to rise, I would suggest a second (safety) cooling loop with a factor 10 higher maximum flow and triggered by a second temperature indicator, which should always be able to stop a runaway and switch it completely off.
    There is a similarity with a nuclear fission power station, which is also being operated around the runaway point (‘reactor is critical’). The biggest difference is that I think that a Hot cat that melts down is potentially not very dangerous for people and the environment, but melt down of a nuclear power station is and that therefore the precautions can be relaxed for a ‘critical’ Hot cat.
    Andrea Rossi indicated that this cannot be done because of safety reasons. He will know best. Maybe the Hot cat can explode in case of a runaway, or cause fire or melt through its casing, whatever. I am sure for the time being he wants to walk the safe way and I agree with that. A ‘critical’ Hot cat may be something for the future if the advantages of this approach exceed the disadvantages.

  68. Andrea Rossi

    Gerard Mc Ek:
    We did not see so far exhaustion signs. In this case it is not a matter of crystal ball, but of experience: it is the first time we can see a plant work 24/7 for one full year, therefore we have to learn. From theoretical ( mathematical) calculations the charge should endure at least 365 days. We’ll see.
    Warm Regards,

  69. Andrea Rossi

    James Andrew Rovnak:
    Sorry, I have taken off from your comment a theory that is too nonsensical to be published even in a blog. It violates practically all the foundamental laws of physics. Suggestion: without strong bases, better let alone theories.

  70. James Andrew Rovnak

    Just thinking about how simple all this is Andrea – the big picture of the New Fire with only a few more engineering details to be worked out like you have done in the E-Cat series – thanks again from all of us who see the TRUTH & now for the details, No?

    Dear Andrea,
    I just read the comment you gave to Frank Acland and I wondered:
    Did you see any change in time which may be due to exhaustion or waring out of the ‘fuel’? If so, are you able to extrapolate (calculate) the expected ‘life-time’ of the fuel and it this satisfactory or is this still crystal ball science and hope?
    Thanks for your constant effort for answering all these endless questions.

    I can say nothing until a detailed report is published about those experiments, with all the necessary scientific data.

    The E-Cat is much more complex.

  74. Dear Andrea Rossi,
    The soldering gun is a device where a high amperage 50 Hz alternating current flows in a thick copper wire. The wire becomes very hot at a portion which is strongly curved. (Google ‘soldering gun’ to see images or probably you know such device already.) Maybe this kind of heating approach might be useful in small E-cat units, because it can be made very local and losses are apparently rather small. It is a variant of resistive heating, but one which is specific to AC.
    regards, /pekka

    James Rovnak,

    Thank you for your interest. I need to make a serious correction here. None of the information published by Wizkid was intended for this forum, it was not fueled. There was no SSM because there was no fuel present. There was no SSM.

    Frank Acland:
    These days we are satisfied how things are going on. ( F9 ).
    As you know, the measurements and the report of the ITO after the Lugano test have allowed us a strong improvement, for reasons that we deem confidential, so far. The Lugano Report of the Independent Third Party for us is a gold mine. For this reason I am very curious to read the reports after the replication of the Effect they are trying in the Universities of Uppsala (Sweden) and Bologna (Italy).
    Warm Regards,

  78. Andrea Rossi

    You can find many photos on
    and on
    Also in this blog, going through the 23,200 comments and counting, you will find hundreds of links inside the comments with photos.
    The Hot Cat we are testing here now externally is equal to the Hot Cat of the Lugano Test, whose photos are published on the Lugano Report made by the ITP, published here:
    Next photos, when possible, will be published on
    Warm Regards,

    Dr Andrea Rossi,
    What do you tink of the replications cited in the comments of James Rovnak?

  80. Mark Saker

    Dear Andrea,

    As your know we all enjoy photographs :)

    I know its difficult for you to photograph the 1MW beast but I wonder if you could possibly add a small picture of the hot cat test rig. If your exchanging heat with a fluid then I imagine the reactor is difficult to see so shouldn’t give away any secrets?

    It gives us all something to talk about during this long test :)

    Or perhaps you may have some photos you can share from the earlier years of tests, near the beginning when you first started working with lenr?

    Dear Andrea,

    You wrote:

    “The MW E-Cat is in ssm and stable.
    The Hot Cat is in ssm too, stable.”

    Is this unusual or quite normal these days?

    Kind regards,

    Andrea another one of my monologs of random thought for comments from you & blog members, only if you can.
    I shared this with Wizkid tonight as I thought I’d detected a little (ssm) LENR presence in his shutdown temperature graphs or else I’m just see things? You don’t have to comment on that statement, just save an old man from embarrassing himself again.
    “Just for the record Mats002 I did blow up (magnify) the unfueled test temperature profile on shutdown & the fueled run & there is a bit of (ssm) LENR present that is obvious to me at least. Now Wizkid if you normalize both decay curves to 100 %, that is the nonfueled case divided by 1200 C & the fueled trip case by about 900 C & overplot them, I think you will find that they both drop off initially very fast, but the fueled run runs into a little remnant of decayed heat at about 400 C or about 44%. This is exactly how heat after death appears in current nuclear plants. Now for a clean new Nuclear Plant reactor that is the unfueled analog here. It takes week/months for appreciable decay heat to build.Since Wizkid didn’t run very long nor stimulate enough (ssm) to occur, there will not be much (ssm) present in his decay profile.I didn’t have the data only graphs & my ability with spread sheets has become dismal since retiring 15 years ago but visually & with a few attempts at blowing up portions of both temperature curves until my eyes hurt, I could see the break point at 44% in the fueled run. Would be nice if Wizkid would try this exercise to make an old man happier or show me up for what I truly am. Many experimenters have witnessed (ssm) LENRs presence but just didn’t realize it nor even know it is there IMHO. I’ve said this before I don’t know the decayed heat build up time constants that’s what decay heat specialist are about in big nuclear plants, but I have used their numbers in nuclear plant simulations before with great accuracy in developing control & protection algorithms for a variety of nuclear plants. Hopefully that graph by Wizkid will show the Lady LENRs presence just a little & we wait with baited breath further runs & reports & eventual control & protection of the LENR Ladies process. This development would be cake for the nations National Labs but without a directive from Smart Government (?) they can’t bring their magic to bear here. Thanks to Andrea Rossi’s persistent work ethic that we are finally here today slowly gaining insight necessary for our future well being.Thank you for the great test & efforts Wizkid it is a pleasure to see you operate so professionally as well as others.”


    And thank you again Andrea for this wonderful & insightful forum & discussions.

    talk with Wizkid
    “wizkid James Andrew Rovnak • 9 hours ago
    Hello James. Sharp temperature spikes were inserted to find LENR, but NO LENR FOUND yet . Source uses ardruino controller with custom software, optical a/c solid state switching and a full wave 10A bridge rectifier to produce DC that is used to drive the coil load.”

    Interesting set up, but I think he needs more TRIAC like freq content to stimulate Lady LENR into more dramatic presence like GS3 test, etc!

    We all wait for further testing & a final report with more details to learn more & maybe help Wizkid with ideas & comment of group think, just maybe!

    Have a nice day Andrea, just wanted to share this info from Wizkid with the Blog participants.

    In this moment it is 07.40 p.m. of Thursday, June 25.
    The MW E-Cat is in ssm and stable.
    The Hot Cat is in ssm too, stable.
    Fingers crossed. F9.

    Can you give another spot of update in the very moment you will be able to read this message?

    Dr Rossi Andrea,
    Do you think that the lattice theory of Prof. Norman Cook can explain the Rossi Effect?

    Andrea, some comment over at lenrforum today on latest replication attempt whose report we await for further insight.

    True, but it was a very nice piece of work so far & should not go unnoticed. Think he may need some more high freq EM, not sure how it enters fuel element, but sure it is needed for lots of (ssm) LENR to show up!

    Some people are already spreading disinformation that this works and shows SSM.
    Who needs skeptics when we have such blind believers. :thumbdown:

    Good luck to the new replicator. Keep sharing your progress. :thumbup:

    Liked his power meter. Note all meters have high sample rate DACs to analyze current/voltage inputs for real & imaginary power present, even for TRIAC type noisy spectrum’s & that spectrum’s harmonics & current trace are fundamental to exciting (ssm) LENR of that I am sure tarun, & every bit of information publicly displayed should be discussed here to further our understanding & offer help & verbal support to those who undertake these arduous experiments, No? The World cries out for this New Fire & the lenrforum supports that cry with reasoned discussion by all – dissenters, critics, do-ers, interested followers, experimenters etc.

    You are totally right and I will treasure your savvy suggestion. I’m sure Mr Bezos will comply!
    Warm Regards,

    Dear Andrea,

    Your crystal ball has been placed on back order, but Tom Conover received his. This smells of corporate suppression of the E-cat…

    Time to play hardball.
    Tell “Jeff Bezos” the Founder & Chairman of Amazon that your team will develop an E-cat powered Drone for his home delivery model. He is a savvy businessman & will quickly grasp the implications of this. He will personally deliver your crystal ball.

    At that point, you should up the ante. In return for developing E-cat drones, He shall provide *FREE* delivery of all future E-cat home Heater sales. This is of course dependent on (F9).

    Savvy Business Regards,
    Dan C.

    Let’s wait for a detailed report to formulate an opinion.
    So far I can appreciate the enthusiasm.

    Andrea I think The Wizkid just did it.

    Have a nice evening. Nice to watch these guys replicate ingeniously, No?

    Albert N.:
    The fact that Airbus is making R&D in the LENR field confirms that our work has changed the game, involving the giants. This also gives evidence that it is not true that mainstream science is not interested in LENR.
    About your questions:
    1- We do not talk with our competitors
    2- Same as above
    3- I do not agree ( question: if they do not think LENR can be patented, why did a patent application, that I know very well and have studied with attention and is in good part copied from prior art?)
    Warm Regards,

  96. Andrea Rossi

    Gianni Abbamonte:
    I do not know anything about what they are doing. I know, of course, that they are trying to replicate, in Uppsala and in Bologna, but I am not a rumorist, therefore I prefer to wait for written reports.
    Warm Regards,

  97. AlbertN

    Dr Andrea Rossi:
    I was looking at the LENR patent Airbus filed a few months ago. My understanding is that the request is still ‘pending’. Airbus is an extremely large company and potentially Industrial Heat’s biggest threat/competitor. Airbus Group Innovations VP Chief Scientist Jean-François Geneste has been pushing for more research in the LENR field. Mr. Geneste is of the opinion that the LENR phenomenon cannot be patented. You can only patent the ‘control’ system.

    Jean-François Geneste has a very impressive bio:

    This leads me to few questions:

    1- Have you or I/H ever talked to or met Jean-François Geneste?
    2- Have you or I/H ever been in contact with Airbus or one of it’s subsidiaries?
    3- Do you agree that you cannot patent LENR itself but only patent the ‘control’ system?

    Warm Regards,
    Albert N

    Carissimo Dott. Rossi:
    From many sources seems that the Lugano experiment has ben replicated from the professors that made it both in the Universities of Bologna and of Uppsala, where they made by themselves reactors and charges with the data they got in Lugano. Can you comment?

    Andrea Rossi:
    I came across a very recent communication in Nature (June-23) concerning an improved water-splitting catalyst. The catalyst is nickel-iron oxide, and the key to the improved performance was the introduction of lithium ions. The work came out of Stanford.
    Could there be more than just a coincidence here?
