    Dear Andrea Rossi

    This article in Phs.org may not be directly related to your work but I couldn’t help thinking that you or your team might find a use for it:


    It’s interesting physics and engineering anyway.

    Dear Andrea,

    A recent post on E-Cat World noted the publication of a new paper by Oliver Consa on arXiv: Something is wrong in the state of QED.

    This new paper is an update based on previous papers, concerning the value of the anomalous magnetic moment of the electron (g-factor), the paper clearly lays out the step by step history of the interplay between the experimenters and the theoreticians, how theoreticians were influenced by the test results of the time, how the experimenters published values with wide tolerance bounds to include the published theoretical predictions of the time, the interplay and re-examination of previous work explaining how the official g-factor value has been adjusted up and down over the years, how the value has evolved to become the current accepted value, how the precise determining of this value has been used as a keystone for the validity of QED. However as Oliver Consa notes; “An examination of the history of QED reveals that this value was obtained in a very suspicious way.”

    This paper is essential reading to understand how the current state of physics has been influenced by historical experiments.

    The progress of physics, the determination of equations, the values used, and how each verification experiment relates to the previous can have a long history, the following is from a Caltech 1974 commencement address given by Richard P. Feynman:

    “We have learned a lot from experience about how to handle some of the ways we fool ourselves. One example: Millikan measured the charge on an electron by an experiment with falling oil drops and got an answer which we now know not to be quite right. It’s a little bit off, because he had the incorrect value for the viscosity of air. It’s interesting to look at the history of measurements of the charge of the electron, after Millikan. If you plot them as a function of time, you find that one is a little bigger than Millikan’s, and the next one’s a little bit bigger than that, and the next one’s a little bit bigger than that, until finally they settle down to a number which is higher.

    Why didn’t they discover that the new number was higher right away? It’s a thing that scientists are ashamed of — this history — because it’s apparent that people did things like this: When they got a number that was too high above Millikan’s, they thought something must be wrong — and they would look for and find a reason why something might be wrong, when they got a number closer to Millikan’s value they didn’t look so hard, and so they eliminated the numbers that were too far off, and did other things like that. We’ve learned those tricks nowadays, and now we don’t have that kind of a disease.”

    Also of interest in the Consa paper is the example given regarding how the Casimir equation was determined, that the equation was determined by a renormalization technique, the use of the Riemann function, the equation works, is known to accurately predict experiments, it is the accepted equation for determining the Casimir effect force per unit area. However as I have previously posted here, maybe it is an approximation when used at the scale of electrons.

    Dr Rossi:
    When will I be able to preorder an Ecat SKL? It would be more useful to me than the SKLed. I think this is true for most of your followers, and I think you would get many preorders of it after presenting it on Dec 9th.

    Dear Andrea, dear Colleagues,
    I suddenly found an interesting article “LENR: pseudoscience or scientific revolution ?” for your attention. It is available on the main page https://strana-rosatom.ru and direct link https://strana-rosatom.ru/2021/10/12/lenr-lzhenauka-ili-nauchnaya-revoljuciya/
    Its significance lies in the fact that this newspaper is the official publication of Rosatom and, therefore, such a powerful energy Russian company as Rosatom drew attention to alternative energy sources based on LENR, despite the financing of projects like ITER.
    The article is short and it briefly discusses such issues as the emergence of LENR, the state of the problem, transmutation of elements, theories, the ECat and products for sale and others. Now it begins to appear at other web-sites in particular on http://www.lenr.seplm.ru
    It is of course in Russian. But if needed I or somebody else can translate it into English and create a link.
    Best regards,

  • Brice

    Dear Dr Rossi,

    When you say that the COP of the SKLed is about 8, do you mean that this was calculated over the total consumption of the whole SKLed (4 W) or only over the part of the reactor plus the LED (2 W), without the electronics (2 W). This would finally be the difference between 16 W or 32 W output.

    Thank you for your reply,

    Dr. Rossi,
    Do you envisage the EcatSKL as a device which can operate independently of a grid connection? Will your demonstration unit do so?
    I understand the safety concern in operating the SKL with a power source which, itself, depends upon the operation of the SKL. Intuitively, though, this doesn’t seem like an overwhelming problem. Can you explain the complications that have made it difficult to achieve an EcatSKL which operates independently of the grid?
    Looking forward to December (not something I would usually say!).

    @Gian Luca,
    I would suggest to substitute “LENR” against “ambiant energy conversion” in the pedition and do some more advertising. If we reach 500 I will spend some more money for advertising.
    Best regards,

    Dear Dr Rossi,

    There are many small Portable Power Stations currently available on the market which are useful for camping and off-grid supply. They provide mains voltages derived from the stored energy in mobile battery packs, typically using LiFePO4 batteries which are safer than Lithium ion batteries.

    A typical unit can provide 240Wh of power at a rating of 200W but units with larger capacity are also available. They provide electrical outputs at 240v AC, 12v DC, and USB connections at 5v DC. These small units are designed to be charged from the mains supply, a 12v vehicle socket, or trickle charged from a solar panel.

    I expect that one of these units would easily support multiple Ecat SKLeds.

    My questions are:
    1. Could one of these units provide sufficient power to an Ecat SKL or Ecat SK for a limited time of operation?
    2. If yes, would it be possible to use the electrical output of the Ecat SKL to concurrently charge the same Portable Power Station?
    3. If yes, would it be possible to use the electrical output of the Ecat SKL to concurrently charge a separate Portable Power Station?

    Many Thanks if you can answer these questions.

    I am greatly looking forward to your presentation on 9th December.

    Kind Regards,
    Martyn Aubrey

    @richard wells
    SSM is easy to achieve. Just plug the ecatSKL to a powerbank with an outlet of 230 or 110V.

    Dear Mr. Rossi,
    is the certification process of the ecatSKLed finished and ready?
    is the certification process of the ecatSKL still well on the way?

    Best regards

  • Gerard McEk

    Dear Andrea,
    I hope you can give us some details on the progress on the Ecat SKL.
    1. Has it reached a stage that it can be integrated in a product?
    2. I guess you will continue to develop it further, on which aspect is your focus?
    a. reliability; b. higher output power; c. producibility; d. production cost; e. some other aspect
    3. Will it definitely be demonstrated on the 9th of December 2021?
    4. Will it be demonstrated in Self Sustaining Operation?
    5. Will it be loaded (with lamps, heating elements or something else) to show clearly it is actually producing energy?
    I know 9 December is approaching quickly and no doubt will increasingly take more time of you and your team.
    The number of visitors to the presentation of the SKLed and SKL will be limited. Is it only open for invitees or can anyone ask for attending this great event?
    I wish you good luck in the preparation of the presentation.
    Kind regards, Gerard

    Dear Andrea,

    Isn’t this the perfect opportunity to expedite acceptance of the Ecatsk by helping china get rid of coal?

    Warm regards,
    Chuck Davis
    Maybe. But do not give them access to a single Ecat unit. Sell them electric power at a rate that will enable the recouping of some of the hundreds of billions of dollars of IP they have stolen over the few decades.

    Dear Readers:
    Today on the Journal of Nuclear Physics has been published the paper “Novel Cold Fusion Reactors Based on the Real Cold Fusion Mechanism”, by Noriyuki Kodama.
