    Dear Andrea!

    We believe that you have chosen the only right tactics and strategy for the smooth entry of the revolutionary E-Cat energy technology into the global energy system. By ensuring the sustainability of the energy source market when switching to an environmentally friendly, safe, cheap and limitless source of energy, you take into account the interests of all market participants and thereby protect the economies of different countries from possible shocks and crises, giving time for a smooth restructuring of energy systems. Fully controlled by Leonardo and its partners, the transition to a new energy production technology will allow for a thoughtful and calculated from all sides replacement of obsolete energy sources with new ones according to the developed plan. We are confident in the success of the implementation of the ambitious plans of LEONARDO and wish you good health, dear Andrea!

    With deepest respect,
    Irina and Vitaly Uzikov

    Today the E-Cat is being introduced,
    The start of a new era begins
    People can never be excused
    Not to use its energy, since

    It is powerful and very clean
    It uses only little resources
    No CO2, what does it mean?
    It may stop global warming causes

    Running out of polluting energy
    May now be stopped forever
    No reason for future anarchy
    Yes, this product is clever

    So people, promote the E-Cat now
    Help to bring it into the market
    You know it gives future, that’s why and how
    It really must be your primary target.

    Dear Dr Rossi,
    I suspect that the video will be fairly boring, showing an inanimate object with various gauges that one must squint at to read.

    Why not introduce a little drama by splashing a bit of water on some of the bared heat pipes. In other words, show some steam.

    Dear Dr. Andrea Rossi.
    Today is an important day, we are all waiting for this presentation.
    I hope that this is the beginning of a new stage – the beginning of the commercial activity of Leonardocorporation!
    I wish you success! And good health!
    Since September 2015, I have been reading your blog and will be closely watching your progress.

    Dear Andrea Rossi,

    You have a rare opportunity that very few people will ever have. With the E-Cat SK, you have a technology that could not only supply the planet with a plentiful and clean source of energy, but the most profound discovery made in perhaps the last century. Today, at the presentation, it will be your choice whether or not to disclose the information needed to forever awaken the world to the fact it exists: or, on the other hand, continue down a strategic path of limited disclosure that keeps virtually all of mankind ignorant of the breakthrough you’ve made and the potential it holds. As you indicate, the SK is at this time a commercial product, already beyond the stages of theory, experiment, and prototype. This puts you ahead of your competitors, most of whom are still tinkering with powder based systems. But to serve the true purpose of your discovery so that it will be universally accepted and utilized by all humanity, you must have faith that the source of all knowledge will make sure it shines brightly if you let the world see what you have discovered.

    Matthew 5

    Ye are the light of the world. A city that is set on an hill cannot be hid.

    15 Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.

    16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.

    Technologically speaking, the SK is the brightest light on God’s Earth, and he gave you the intellect, work ethic, and inspiration to create it in the first place. If you take it out from under the bushel of secrecy to reveal its wonder and potential, I have confidence God will allow it’s potential to finally be revealed to humanity and your many years of sacrifice and hard work to be recognized and rewarded. It’s time humanity learns that not only is LENR a reality, but a refined, commercial system is already completed. Not a few clients, not a few followers of your journal, not the currently minuscule LENR community: but every last living soul on this planet. All it will take is faith.

    This is your chance to walk on water.

    Let go. Let God.

    Giuseppe, someone says exactly the same with me. In an answer to his readers, the (most) famous italian contemporary journalist Indro Montanelli recalled his interviews with recognized geniuses around the world during his career; about physicist Enrico Fermi, he described him as a totally dumb person, up to the point that it was completely useless try a conversation with him on general topics. He also extended this characteristic to almost all the scientific geniuses he met, apart from Einstein, who described as an amazingly interesting personality. So probably you and me became pure asinine geniuses after following Andrea; and Andrea himself, who was already a genius, is supposedly at high risk in my opinion.

    Dear Andrea,
    as many others here i m following this blog daily since 2011, for this reason my wife say that i m becoming “rimbambito”.
    I m sure, it is not.
    Tomorrow is “the day” and it can be my and our revenge.
    Proud to have been on these pages for so long.
    Best wishes, Giuseppe

  • Dear Andrea,
    Thank you for your answer to my Casimir force consideration. Now, I have another point. I looked at Parkhomov’s isotope data, it’s tables in his paper. Many new elements seem to appear, but I don’t find evidence for changed isotope ratios. That is suspicious. Maybe it’s chemical enrichment and not transmutation, in his case. There is, I think, a mechanism how such enrichment could occur, with LENR: Local ionization breaks up molecules in fluid. It also creates free radicals. Those radicals react with the nearby solid surface. In this way, minor impurities might get enriched at the surface near LENR hotspots. (Not sure if hotspots occur in your case, but that’s not the point.) So I say this: when researching the transmutation signal, beware of false positives.

    Earlier I took for granted that the energy must come from the nuclei, because where else could it come from. Now I am not quite so sure any more. Maybe (just maybe) it is something more exotic, like creation of negative mass stuff. Since dark matter and dark energy exist, we know that the standard model is not quite complete. Recently there was science news that X-ray telescope quasar data indicates that dark energy has depended on time. If true, it indicates that dark energy is not vacuum energy, but some “stuff” that has some dynamics. Maybe negative energy particles, like Jamie Farnes recently suggested in his recent controversial paper. The point regarding the E-cat: If you see evidence for genuine transmutation, good. If not, maybe it’s not necessarily a measurement error.

    Dear Andrea:
    How is calculated the price of the heat to make it surely convenient for the client, considering that the consume depends on the temperature difference?
    Good luck for the presentation of tomorrow,

  • Jeff Smathers


    I wish you the very best life and success with your efforts.

    Can you please say if there are any constraints by persons or any government agency to
    manage the use of or control the release of technology based on your system and science?

    If you do not post this I will assume the affirmative.

  • Andrea Rossi

    Koen Vandewalle:
    Please read carefully my paper.
    Skip the math, just get the concepts, especially in par. 1,2,3,4.
    Your observations have nothing to do with it and photons are not rings.

    Pekka Janhunen:….. elecrons are current rings.

    Are photons also some kind of rings ? If they are, is it reasonable that they do not have a higgs-boson-core, but can add up to an electron or be substracted from an electron ?

    I’m just trying to study and understand things.

    Dear Andrea Rossi,

    I was watching a Science Channel documentary on space junk orbiting around the Earth. There are thousands of pieces in orbit. It comes to mind that eCat SK technology might have an application.

    I suggest a robotic spacecraft, powered by an eCat-SK reactor (once in orbit around the Earth), that is directed to search out small space junk (screws, broken pieces of solar cells, etc.) and then uses the intense UV light to vaporize the space junk both towards the Earth or away from the Earth, effectively lowering the particulate mass of the space junk (vaporizing it) and bringing it out of orbit (to be consumed in the Earth’s atmosphere) or to reach escape velocity to leave the Earth. Some of the space junk could also be used to propel the robotic ship to capture the next assigned piece of space junk.
    I assume you are very busy with the demonstration. I hope it goes well.

    Steven N. Karels:
    1- yes
    2- the many reactors
    3- This is not an information that interests our customers. We just deduct the price of the energy we consume from the price of the heat we sell.

    Dear Andrea Rossi,

    You replied:
    “1- wrong. This is the maximum power sustainable for a single control panel
    2- confidential
    3- what do you mean?
    Warm Regards,
    Dear Andrea Rossi,
    1. So I understand the maximum current eCat-SK reactor assembly will output a total of approximately 1/4 MW of thermal power?
    2. I assume the Controller interface will be the same as the single unit?
    3. Although the Controller itself may be of a different size/capability?”

    Could you please clarify, consistent with your confidentiality requirements, on the following?

    It appears on the current eCat-SK variant, that you have stated that up to 10 of the eCat-SK reactors could be combined within a single assembly. You also indicated that a Controller would be required to control the operation of one or more reactors. You also used the term “single control panel”. I believe you had also stated that a different Controller would be required between the 20kW eCat-SK reactor and the 100kW eCat-SK reactor, although I could be in error here.

    1. Is a “Single Control Panel” equivalent to a Controller?
    2. Assuming a delivered system may consist of a single eCat-SK (current variant) or a number (up to 10) of these reactors, may the same Single Control Panel be used to control the one or the many reactor(s)?
    3. If possible, it would nice to receive a narrative description as how different power levels are provided, changed in the field, maintained, troubleshot, replaced, modified in capacity, etc., consistent with your Confidentiality requirements.

    Dear Andrea

    Succes with the coming presentation

    Another inventor I would like to bring to your attention


    is also into capturing light far more efficiently for cheap solar energy… hinting on another nobel prize
    who knows the light of the E-cat can benefit from it….

    96 years old my respect….I wish you the same health…


  • Michel

    Dear Dr Rossi,

    First of all, thank you for the theoretical update you promised !
    380W is a significant consumption for the control system, given that the input power of the reactor is comparatively very low. The question is where does the difference go:
    – Is this regulator built from a PC chassis, or have you created your own electronic circuitry?
    – Do you use additional RF heating for plasma (as is the case for hot melting)?

    A commercial solution for the controller is attractive for the software aspect, but is generally not optimized for consumption. If the design has been developed internally, there may be room to improve the regulator’s power consumption (some microcontrollers, FPGA) what do you think?
    Anyway, the overall COP of x58 is already impressive !



  • Patrick Ellul

    Dear Andrea,

    Thanks for your answer regarding investment. You are right that the SEC regulates “crowdfunding”. It is possible and many companies much less mature than yours do it already. I do understand that for you it has little benefits and this would probably be a distraction. You don’t need the money. You would only do it for your supporters.

    For your readers, here is the official regulation from the
    SEC website. https://www.sec.gov/smallbusiness/exemptofferings/regcrowdfunding

    Thank you for your dedication to read my paper!
    Warm Regards,

  • WaltC

    Dr. Rossi,
    I could be interpreting this wrong (clearly), but your Researchgate paper seems to hint at the possibility that a functioning deuterium based E-Cat is possible with calculateable shifts in the input NMR frequency and output emission spectrum frequency. If true:
    – would that be considered additional confirmation of your paper’s thesis?
    – Is that something you’ve tried or plan to try?

    Interesting paper, by the way. It’s very much beyond my level of physics training, but I found it very readable and quite intriguing, nonetheless.


  • Drew G.

    Dr. Rossi:

    Now that the ECATSK has been industrialized, this may be of interest to Leonardo Corp.:


  • Julian

    Dear Andrea:
    Congratulations for your paper on Researchgate. I am impressed also for your progress concerning the theory.
    Anxious to see the historic presentation of the 31st,
