RE: The Playground
Negative muon strong source [if any] future use
... Nuclear transmutation of FPs by negative muon capture reaction was simulated by PHITS. It was
found that target nuclide with an atomic number of Z is mostly transmuted to nuclide with an atomic
number of Z–1. As a result, for our investigated case, 61 % to 87 % of stopped negative muons
contribute to transmute target nuclide into stable or short-lived nuclide. In the case of 137Cs, 26.7 %
of 137Cs is transmuted into 135Cs which have longer life-time than original nuclide. The irradiation of
negative muon beam was also simulated. The result indicates that the position of transmutation by
negative muon capture is controllable by changing incident energy of negative muon. From a rough
estimate, it takes about 8.5 × 106 year to transmute 500 g of 135Cs with the negative muon intensity of
108 muons/sec. We conclude that much higher intensity of negative muon source is required for
transmutation by negative muon capture reaction.

Possible heat production in some Ni-H and Ni-D systems
Abstract
The paper concludes two year research on the topic of the possible heat production
in nickel-hydrogen (Ni-H) and nickel-deuterium (Ni-D) systems during heating that was
initially announced by S.Focardi, R.Habel, F.Piantelli and later reported by A.Rossi and
A.G.Parkhomov. The authors developed a new methodology and new testing units that could
provide consistent results for the physical community due to high importance of such reports
in the wake of energy crisis. The testing units were engineered with such a design that
both nonlinear heat losses (convection and radiation) during the experiment were minimized.
The experimental methodology is based on the statistical hypothesis testing of the normal
distribution from experimental heater power consumption data samples while the temperature
is stabilized by the PID controller according to the provided experimental program. This
methodology was tested by artificially supplied heat sources and sufficient accuracy was
confirmed around 1.5-3.0%. Around 50 experiments with fuel were conducted with various
additional ingredients, different forms of Ni, pure hydrogen and hydrogen-deuterium mixtures
according to the experiments cited above. No statistically significant levels of the heat
production were found in any of the experiments, with less than 1.5% accuracy in terms of
heater power consumption.

McKubre fits not bad the expectations build in Google academic minds - think at a sort of employing interview: do you prefer borderline neutrino and muons inmeasurable showers ["we need CERN to be sure"], or the reassuring professionalism of a Menlo Park lab expert?
"Heat transfer moves at sound speed, nuclear at the speed of light": elementary consideration relegating 99% LENR to irrilevance from a practical point of view. I smile of last Storm patent request - once more the forced reflex of ANY researcher smelling a tiny bit of success in LENR puzzles from 35 years to this day.
Ten years ago I asked a BIG sperimentalist in nuclear paraphernalia about. His answer: " it's sure that a few palladium-deuterium systems source TWOFOLD neutron fluxes over natural background - and so? No use, no valid theory - My CANDU yields 1018 neutron on 4pi right now [perhaps pro second, I don't remember] - this suffices to kill my interest on cold fusion whispers."
Conversely, I am not sure that 30 years of no or dubious results are a good starting point to settle question. Occam razor, Dirac sea, peculiar nucleus models, deformed space-time, Sindone neutrons, plasmoids, strange radiations, magnetic monopoles from running motors in Chernobyl basament etc. have obviously small or no appeal at all for Maryland University and Google money. The same for interstellar flights into drilled Rydberg clusters at cosmic scale and zero-point energy pumps.A lot of background noise covers subtle realities, and it's a pity. And much of this noise don't originate from cold fusion enemies. Piantelli said once we need 50 years or more to catch the cat, an optimistic view - 20 are already gone, and 12 count from AR's bombastic start.
