    Hello Robert, robert bryant

    In my opinion your assumed average convective heat transfer coefficient of 4 is too low.
    Calculating the convective heat trannsfer coefficient with the method used in the Lugano report I get different values.
    Note that I…

    Robert,

    Did you in your calculation include the dissipated heat of the vertical outher walls ?
    The convective heat transfer coefficient for a vertical wall is more effective and has a value twice that of the round area which you…

    From the figure in the document we see that the internal thermocouple was a Tungsten-Rhenium thermocouple
    Tungsten-Rhenium thermocouples can to my knowledge be safely used in an Hydrogen environment.

    The whole magnetic field thing is complicated. Sometimes a static field is good, sometimes a varying field. And on other occasions one or the other can kill everything. It's very hard to make any sweeping generalisations about it.

    In doubt, I believe that might be the safest choice. This specific subject is complicated by the possibility that the presence of a uniform magnetic field might not be unconditionally harmful, and certainly there have been reports or suggestions by…

    If indeed a magnetic field is harmfull to the reaction, then the (cartridge) heater used in Mizumo systems shoud have a bifilair wound coil to minimize the magnetic field.

    It has also been my conclusion that the presence of a magnetic field has a possible negative influence on the LENR reaction

    I once questioned Rossi on this on his blog on the subject, his answer was that he could not give an answer since…

    There have been suggestions that physical separation of the fuel ingredients is the answer to the 'coating'problem.

    The exact quote where Bob tells about this:

    Iterations.
    When I first visited Parkhomov in early 2015 - he showed me mountains of failed experiments. Parkhomov, tries fails, tries fails, etc. we did not have the time to repeat cycles, so we

    In his AP2, PROTOK-6 and VV3 reactors Parkhomov used as fuel a combination of nickel powder and LiAlH4.
    According to Parkhomov all three reactors produced excess heat.
    That would not be the case if LiAlH4 is killing the reaction.
