See McKubre's replication of the Arata experiment.
I didn't see mention of it there.
Regarding the pressure from electrolysis, it far exceeds anything
that can be accomplished with mechanical means such as pumps. See
Mizuno's book, chapter 7. I think the fact that gas loading works
means that high pressure is not required for a cold fusion effect. I
guess it means that high pressure is not needed for high loading;
there are other ways to achieve that, rather than brute force.
Mizuno's book isn't available to me. When we are talking about a
local effect, something that only involves perhaps, primarily, say
two molecules of deuterium gas and their relationship in confinement,
the concept of "pressure" is trickier. I'm thinking about how the
Takahashi's TSC might come to exist. If I'm correct -- always a huge
"if" -- that configuration requires energy to form, the molecules
would have to be pushed together in some way. The pushing could
merely be their momentum in a collision, but, again if I'm correct, a
collision that would otherwise bring the four deuterons involved into
the tetrahedral symmetric configuration would cause the molecules to
dissociate. So there must be some resistance to dissociation, which
could be supplied by the lattice. Deuterium gas doesn't ordinarily
exist within the lattice, the lattice itself causes dissociation.
I don't think anyone knows enough about the behavior of deuterium at
the interface to calculate the frequency of TSC formation. It would
be very low, but the incidence of fusion is very low.
Meanwhile, I'm generally interested in this phenomenon of high
pressure build-up within a hollow palladium tube, caused by
electrolytic loading. That loading must create a barrier that the
deuterium cannot cross, and while the barrier is low in voltage, the
pressure equivalent must be high. It was said here that this could be
used to generate free energy (and was therefore doubtful), but this
assumed that the rate of flow was high enough to make up for the
current flow necessary to maintain that barrier. You can get very
high pressure, but not high flow rate, equivalent to, with charge,
getting very high voltage but with only very low current available,
as with a Van de Graaf generator.
We already know that, even without electrolysis, loading ratios of
1:1 or higher can be obtained by gas loading. That's close to
equivalent to hydrogen metal at room temperature, which is clearly a
high-pressure equivalent. But that hydrogen cannot flow rapidly,
unless the lattice is destroyed. Do not toss fully loaded palladium
into a furnace, you might be quickly less one furnace, just from the
release of pressure. Simply heating the palladium to a few hundred
degrees doesn't cause extremely rapid release, or those cigarette
lighters would have been really, really dangerous.
