Rossi Comments on Theory and Radiation

Given the discussions we have been having here regarding the possible mechanism behind the E-Cat reaction, I thought it was interesting to see a couple of Q&A’s on the Journal of Nuclear Physics in this area:

Dear Andrea:
Which is the peak quantity of the specter of the radiations you have been able to detect inside the Ecat?

Andrea Rossi

Borderline in between X-Rays and Gamma, around 50 keV.
Warm Regards,

Dear Andrea Rossi,
Did you change idea about the chance that electron capture could explain the LENR?

Andrea Rossi

JP Renoir:
Absolutely not. Electron capture in LENR is impossible. It can happen only with atoms overweighted with protons, and this is not our case.
Warm Regards,

Rossi has always said that the E-Cat is perfectly safe because they never are able to measure radiation beyond background levels outside the E-Cat, but here he clearly states that there is radiation inside the reactor that somehow apparently never escapes. For a quick reference, here’s an image from the Mirion Technologies website about different types of radiation and the shielding required to block them.

    I think these are very interesting answers by Andrea Rossi especially the X-Ray spectra peak.

  • Barbierir

    No aswer by Johnson, Fabiani or Penon yet but Fernando S. Aran is the new attorney on behalf of J.M. Products, Henry Johnson and Quantum Leap

  • Observer

    Does “the peak quantity of the specter of the radiations” refer to the highest energy photons or the wavelength of peak intensity?

  • Fedir Mykhaylov

    The machine-in the sense of microscopic natural accelerator

  • Steve Swatman

    Rossi has always said that the E-Cat is perfectly safe because they
    never are able to measure radiation beyond background levels outside the E-Cat,

    Are you sure?

    I believe that Mr Rossi did detect neutron bursts when he his reactor ran at “Very COP” (around200+) I think I read it on this site too, but it was quite a while ago, maybe 2yrs back.

    there were also a couple of others Me356, 2 Swedish scientists Lidgren and Lundin, who stopped experimenting because of neutron bursts at very high COP, also around 200+

    The thing is, they are perfectly safe when run at lower COP levels and of course they are surrounded by water. so long as they do not dry up, explode or run at stupid COP,

    “neutrons can escape from the E-Cat, if it is pushed to certain limits,
    and much of Rossi’s work has been to make sure that production models of
    the E-Cat are never allowed to reach that point. The control systems
    that Rossi and his team have developed are therefore of great importance
    for ensuring the E-Cats operate in a completely safe manner.”

    • From Città del Capo Radio Metropolitana Interview With Andrea Rossi, Sept 2012: “The main effect is the thermalization of low-energy Gamma (50-120 keV).” Reported in ECW:

      • GiveADogABone
        Part 2 – The Theory
        2 years ago Rossi and Focardi believed that energy production was due to transmutation of Nickel into Copper. In these years, all the experiments have made it very difficult to believe that the process was so.

        The main effect is the thermalization of low-energy Gamma (50-120 keV). The transmutation of Nickel into Copper is a side effect. In fact they have found traces of Copper in the dust, but this does not justify the energy produced, because they should have found more copper.

        So, that is the end of the Copper. Where does the 50-120keV gamma come from? Can they generate 6.7MeV protons or is that also a side effect or a completely different pathway for Piantelli?

        This seems to explain the function of the lead in the E-cat. Whilst providing the shielding, it also provides the heat source for the water boiling.

      As cited in the link you provided, Rossi has said that during the R&D process that neutrons had been detected when they pushed their experimental reactors to high COPs. Since then he has said they have worked to ensure that commercial E-Cats don’t produce any radiation outside the reactor.

        Dr Andrea Rossi,
        News about the QuarkX?
        Andrea Rossi, August 29, 2016 at 10:36 PM

        This will be an important week.

        Warm Regards, A.R.

      • Steve Swatman

        I understood that Frank, I wanted to cover the point before the shills jumped on it. 1 perceived error is usually enough to get them filling a while thread.

      The process that causes the slow neutrons is likely similar to the Genie reactor proposal their reactor has been claimed by some to be LENR. Even if Rossi’ process work very differently than the Genie it might make a good trigger for a hybrid reactor to burn up waste or uranium ore. Fission that could be essentially turned on and off by a switch, that also fails safe because if the trigger melts the neutron flux lowers and stops could be very useful for energy production.

    Dear Andrea Rossi,

    considering the many variables we must consider (technical, legal, political) and consequently the difficulty in being precise in predictions, may you now make a schedule of upcoming major deadlines in the long road of E-Cat?

    I’m sure that on certain issues you will be forced to repeat yourself, but I think it is interesting to have an overall timing pattern that reflects your feelings today. Obviously without obligation . . .

    Thanks so much,

    Dear Andrea,

    Why will this be in important week for the QuarkX?

    Many thanks,

    We have to make a test that should be conclusive for the first stage of the R&D, if positive.
    Warm Regards,

    With regard to Lugano and photons, the fuel was preprocessed if you consider the SEMs, and I already discussed and rationalised that if you passed the initial “burst” in this processing step you would not see the signal 7 type spread.

    I deduced that a tungsten sheath would prevent post “burst” emissions (when they are below 120keV) and subsequent to this analysis it was established by looking through a database of Rossi’s blog (which I never read) that he had said this in the past was part of the HotCat design.

    Lastly, we identified that the Neutrons occurred below the melting and wetting temperature of Lithium Hydride (LiH) when they would have a free path. When the Lithium is wetted to the Nickel, it is an effective neutron moderator. In addition – we saw no neutrons at higher temperatures, so in our opinion, based on our data, David Bianchini should not have see neutrons at the operating temperature of the reactor.

    The protocols for our up and coming experiments will explore this hypothesis further, however, we will have more realtime neutron detection with various degrees of moderation due to the excellent open work of Bob Higgins.

    These comments by AR are signatures of bremsstrahlung radiation :
    Part 2 – The Theory
    The main effect is the thermalization of low-energy Gamma (50-120 keV).

    Dear Andrea:
    Which is the peak quantity of the specter of the radiations you have been able to detect inside the Ecat?
    Andrea Rossi
    Borderline in between X-Rays and Gamma, around 50 keV.
    The X-ray spectrum
    As a result of characteristic and bremsstrahlung radiation generation a spectrum of X-ray energy is produced within the X-ray beam.
