  • Dear Dr. Rossi,

    Your statement, “So far, anyway, it has not necessary to change the charge” is remarkable! Originally you had forecast changing the charge every six months. This is a huge advance to go close to one year at “full power” on a single charge. Was this due to a change in the cell or fuel or is the E-Cat performing better than the original forecast? Huge maintenance cost savings and high reliability factor has been achieved by you and your team so far. 🙂

    Congratulations! Wishing you continued success and more great inspirations.

    Best Regards,

    Daniel G. Zavela

    Dr. Rossi:

    There are many applications that don’t require full power at all times.

    Can you run an Ecat at half power?

    10% Power

    If you are running at low power can you run longer before replacing the charge?

    Alessandro Coppi:
    Thank you for your opinion.
    The E-Cat will be integrated with the other sources of energy

    Hi Andrea
    you defined the success of this technology with this words “Make Customers Earn Money” instead I believe that it in the first years, it will decrease the income of many people, and many workers will loose their work due the petroleum industry reduction.
    Do not you think that could be a great result also making true: “Make the world a better site to live”?
    Having available the fire from Nature made the worlld a better site to live for the mankind, having the “new fire” available, will make our earth, a site much more good.
    Will be the activities related with the employment of this technology that eventually allow someone to make money, if money as we know it now will exist in the future.

    Best regards

    Robert Curto:
    I think the price of oil will return to raise when the world manufacturing production will recover its full power.
    As I said many times, the E-Cat has no influence at all on the oil prices.
    Thank you anyway for the information.
    Warm Regards,

  • Robert Curto

    Dr. Rossi, Oil prices fell below $30 dollars a barrel on Friday.
    It should stay there or go lower.
    If you sell a car, first you have to make every part. Then you have to put all the parts together to make a car.
    They do not make oil, God made the oil, and He gave it to them for Free.
    All they have to do is drill a hole and pump it out, millions of barrels a day,
    at a cost of 50 cents a barrel.
    I look forward to the day when we have 100% Electric Cars, maybe run on an E-Cat !
    They will be happy to sell oil for $5 dollars a barrel.

    Time: 09.10 a.m. of Saturday Jan 16
    After a fighting night we assessed the problem.
    1 MW E-Cat: stable
    E-Cat X: still oprative and very promising.
    Warm Regards,

  • Andrea Rossi

    Yes, we already have set up the Team that will lead Leonardo Corporation, with women and men each of them belonging to the top level of her/his specialization.
    The management is composed by divisions covering manufacturing, sales, R&D, distribution, sales, legal, financial, PR. Yes, I will be the CEO, but there will be also a BOD under the control of the ownership.
    The whole is, obviously, under condition of F9, but the names are already there and each of the selected persons has already accepted the role that has been proposed.
    Warm Regards,

  • Greg Leonard

    Dear AR,
    I believe you still have the original 10kW units in the container. Surely you can switch these in to replace any 250kW unit that drops below its useful power. This should get you to the end of the contract successfully.

  • Andrea Rossi

    1- of course!
    2- because you insulted me and, worse than that, my Team. When somebody expresses negative feelings like you are doing with this comment of yours, they allow me a response, but when somebody insults us, there is nothing I can answer, therefore the publication becomes pointless. There are several blogs whose unique task is to insult us, I am sure you will find there all the hospitality you are longing for.
    3- When I will have evidence that it does not work.
    Warm Regards,

    Steven N. Karels:
    The lifespan of a charge depends on the integration of production, mass ( as you correctly say) and other complex factors.
    About the possibility to match the lifespan of a charge with the lifespan of other components, , I’d say that it is possible to make it with some approximation.
    I mean, all can be changed at the same time even if the componenst will not be exhausted in the same measure: this is surely possible.
    Warm Regards,

  • Andrea Rossi

    Steven N. Karels:
    There is not necessity to change the charge, so far, because the efficiency is not below the acceptable limit.
    As for the remaining questions, I am sorry, but they are related to confidential issues.
    Warm Regards,

  • Steven N. Karels

    Dear Andrea Rossi,

    You posted that you are working on the issue of the decrease in effective COP, possibly related to fuel exhaustion.

    My question is what can you change? I suggest that you would not change the charge of the reactor as that would be “starting over”.

    So am I correct that you are adjusting the control settings?

    If this is so, then the optimal control setting would be a function of fuel exhaustion? Or are there other non-control functions that you can change, such as operating temperature(s)?

  • Steven N. Karels

    Dear Andrea Rossi,

    Is the lifetime of the charge within the eCat reactor merely a function of the mass of the charge and the accumulated or total amount of energy released? By analogy, a gasoline tank has a fixed capacity of gasoline. The time over which the gasoline may be consumed is related to the mileage of the vehicle and the number of miles driven. However, the gasoline cannot be stored indefinitely, perhaps a year or so. Is there a similar limitation in the eCat reactor?

    In your “dream” about using an eCat X reactor to power a streetlight, the possible limitation I see is the lifetime of the LED (around 60,000 hours of operation) and the lifetime of the eCat X unit, i.e., the refueling schedule. Can the eCat X refueling interval be matched to the streetlight lifetime? Would this be done by just adding more charge or are there other issues with reactor lifetime?

  • Repine

    Mr Rossi,
    You said that the 1 MW plant had a decrease of efficiency:
    1- are you preparing the ground for an escape?
    2- why did you spam the comment I sent you yesterday?
    3- when will you confess your technology does not work?
    Good bye

  • Kibbler

    Dr Andrea Rossi
    We understand that the leadership for the development of the E-Cat world production will be held by Leonardo Corporation: it clearly appears reading both http://www.leonardocorporation.com and http://www.andrea-rossi.com
    It is also pretty clear that you will be the CEO.
    Question: did you already organize the management team?

  • Tobias

    Dear Andrea,
    Can you give an update today, after the efficiency decrease of yesterday?

  • Thomas

    Dr Andrea Rossi:
    Which is the point that mainly leads your industrial strategy?

  • Per Thomsen

    Dear Dr. Rossi,

    A successful outcome of your work will, as we all realise, have a profound influence on our world, and on New Year’s Eve you shared some happy thoughts. A successful outcome will also put you in a singular position.

    1. Could you perhaps share something about your own personal motivation for your steadfast work? (Some, perhaps most of us, seek fame, money and/or power; on the other hand, some of us are motivated by curiosity, self-realisation, the need to create,…)

    2. What would you like your long-term legacy to be; what would you like our great-grandchildren to remember?

    Best regards and wishes,

    Dear Andrea Rossi,

    Do you believe the current decrease in COP is due to fuel exhaustion?

  • Andrea Rossi

    No, and I am here on the plant to try to unserstand why and how to resolve the problem.
    This night will be fight.

    Dear Andrea,

    A good understanding of theory is regarded as an important basis for new creations.

    At school we first had to learn the theory, and then came the exercises and practicals.

    Your invention seems to have gone the other way.

    I believe that you have gained a lot of intuitive understanding of things by working with materials, alternating with studying theory.

    Long before there is a theory or evidence, there is intuition.

    Does your intuition tell you that the E-Cat X makes the Carnot cycle obsolete for electricity production ? What I mean is that the electric power output and the thermal power output are in the same order of magnitude.

    I that is the case, you could also answer with “Electric Regards”.

    Kind Regards,


  • Tom Conover

    Dear Andrea,

    All this talk about electric cars! About time… Made me reminisce about a few things …

    When you and I worked on some issues with Craig C @ LTI we talked about some solutions that would help improve issues with Wikipedia … and now you and your web team have done it! Your website is elegant in resolving the history of Petroldragon and related history, and I congratulate you on achieving this important milestone towards (world domination? ha ha ha) success!

    Regarding electric cars, I also previously shared with you my project in 1977 where I took a very pretty 1969 Fiat Sport Coupe with a blown engine, and using plans from Popular Science and a army surplus jet engine starter motor that I rewound as a series motor(15hp) along with 6 golf cart batteries and $2172.08 in cash .. I put together a working plug in electric car that went 43 mph, in less than six months.

    I can’t wait to do it again in 2016 or 2017 with an E-Cat X power supply!

    Thank you for the joy you bring in our imaginative lives where we can see now the Nautilus that Jules Verne wrote about, or the space ships in the Skylark science fiction/space opera series by E. E. “Doc” Smith, or in the tales from Marvel about Iron Man, or even Ringworld by Larry Niven. All of these become possible during the next 5 to 100 years, utterly incredible, if even still science fiction.

    Since I spent my entire career making the software I read about in over 4000 science fiction books come true, I know that science fiction is in many ways a reality today, in fact, I can’t find any scifi better than your web site!

    Again, just saying thank you and congratulations …

    Dr Andrea Rossi,
    As we can see, you are making a strong work also from the theoretical side. Few have understood that the theoretical hurdles you are encountering together with Prof Cook are intrinsic in the matter and that you are structuring yourself for the task, as you always do. If somebody will be able to write a solid theory, that somebody is Cook and you.
    As well as you have been the first in the technology, you will be the first in the theory. Few have understood this, but I net on this.
    God bless you

  • Babin

    Dr Rossi,
    The decrease of efficiency you said this morning has been resolved, I hope.

  • Andrea Rossi

    Pekka Janhunen:
    Thank you for your insight.
    As I said, we ( Prof Cook and I) must make a hard work based on the data recording and mathematical evaluation before adding anything about this issue. At the state of the art we are in, every discussion would be useless chattering and any insight , like yours, can be either correct or not from our point of view.
    When and if we will be able to substantiate our idea of theory with solid physical and mathematical evidence, we will publish what we have to.
    Warm Regards,

  • Andrea Rossi

    Andrea Rossi,

    Can you comment on any aspects of the Electric E-Cat X energy production?

    That is:

    1) Is the electric E-Cat X ‘generator’ subject to the usual Carnot efficiency formulas: (heat source @ T-hot and heat sink @ T-cold)?

    2) Is the ‘T-hot’ heat source temperature measured at the E-Cat thermal input or from the E-Cat thermal output?

    3) Does the electric E-Cat X use a ‘familiar’ heat transfer fluid? e.g. water, super-critical CO2, gas cooling, electron flow?

    4) Can you use (a fraction of) the filtered current output as an input signal to the control system to control the operating point of the E-Cat (temperature, start/stop times for the self-sustain mode intervals, monitor power level changes etc.?

    5) Since the E-Cat may contain Tungsten, could you also call it an E-Cat W?

    Thermal Regards,

    Joseph Fine

  • Brokeeper

    Dear Andria,

    With your response to Hergen, you describe a 20KW E-Cat X device the size of a 20 cigarette packet at approxamitely ¾ lb, are you then able to produce individual 1KW E-Cat X units the size of one cigarette? If so, are twenty cigarette size devices stacked to configure about the size of one cigarette package or are you speaking of a single 20KW unit (you mentioned manufacturing 1KW units to optimize production/assembly costs)? Or, for confirmation, did you mean to say twenty cigarette packages (1KW each) stacked to configure the size of a cigarette carton?

    Either way this is a staggering leap of achievement for energy (heat/electricity) per device volume density. The implications of the number of its applications is now an order of magnetude for any size.

    With no end in site of of E-cat X density/ volume evolution, I am also a little concerned about the white elephant standing in the middle of the room (wearing sunglasses) no one really wants to talk about – the wrong-hands-use security. Any thoughts on this issue?
    With much respect,

  • Dear Andrea,
    Thank you for your detailed answer to my earlier criticism of one aspect of Cook’s presentation. I want to make two additional points concerning this topic.

    1) Concerning your answer to Peter Forsberg. Philosophical interpretation of quantum mechanics aside, QM and QED are well-defined mathematical recipes (and in some sense theories) for calculating numerical results. Although I do not personally know any of them, I am sure that there are people in the world who can perform practical calculations in QED and QM. In cases where there is only a single particle or quantum involved (or playing the primary role), I am certain that there are well-defined answers to the questions you are asking and people in existence who can find them. The only issue is to find the people with relevant expertise. Quantum mechanical many-body phenomena are another story. There the level of difficulty can be substantially higher, depending on the case.

    2) Considering a gamma decay chain of a nuclear excited state, even though many of the transitions are much less than 1 MeV energy as pointed out in Norman Cook’s slides, I think that some of them are anyway larger than 100 keV. Assuming that this is the case, you might already now be able to disprove this model by just considering the fact that outside the E-cat, no radiation above background is detected. I am not able to give a precise numerical answer because I do not know exactly the material and thickness of the reactor wall, but I would guess that this is the case, also remembering that the power of the E-cat is very high in comparison to typical radioactive sources. High power output means that even if only a very small fraction of the output energy occurs as quanta that can penetrate the wall, significant radiation counts would then be detected outside the wall. My point is that perhaps you do not need to go to the trouble of trying to measure the gamma ray spectrum inside the reactor, because it might be possible to rule the model out already based on experimental data that you already have (because you know the properties of the reactor wall and geometry precisely).

    Of course, measuring the gamma spectrum inside the reactor would also be nice because all measurements increase knowledge, but I would think that accurately measuring the isotope ratios of fuel and ash would shed more light to the problem. Those were measured in the Lugano report, I know, but the results especially concerning nickel transmutation were partly “impossible”, probably due to incomplete sampling, as has been discussed earlier, therefore detailed conclusions were not possible to be drawn from them.

    best regards, /pekka

    10.30 of Friday Jan 15th:
    a) We have a decrease of efficiency, even if still in the field of good COP. We are studying the situation
    b) I can anticipate nothing.

    Dear Andrea,

    a) How is the 1 MW plant doing today?

    b) Do you anticipate at this point that the test will conclude in February?

    Many thanks,

  • Andrea Rossi

    Got your point.
    Warm Regards,

  • Andrea Rossi

    Dr Peter Forsberg:
    Thanks to you for your attention; by the way: QED and QCD, as you know, are very complicated and many different interpretations of them have been theorized; therefore, the sustain given us from the interpretation made by Feynman is not enough to substantiate what we, Prof. Cook and I, are theorizing. Substantial experimental data and advanced mathematical models will be necessary for us to sustain a theory, and we are still not ready for that.
