Amaud, I have no doubt EM stimulation will enhance the LENR reaction.
The only question is whether Rossi is successfully applying such
stimulation. Based on the design of the hot-e-Cat, I do not see any
indication of EM being applied. The suggestion hat it is being created
in the black box is pure guess. Rossi is an engineer. Engineers try
to make their devices as efficient as possible. This design is not
efficient for applying EM of any frequency. Therefore, I doubt this is
being done here.

That could be superwave as discussed here http://www.mail-archive.com/vortex-l@eskimo.com/msg80933.html

You say that the Ni/H reaction has shown no need of EM stimulation
but that was always at a low rate reaction. The secret Rossi sauce
could be somewhere there. EM stimulation could enhance the rate of
the reaction.
That’s not a fact I know.

Amaud, we do not know this is as a fact. That conclusion is only
proposed. We only know the black box controls the temperature
INSIDE, probably in a complex way. The Ni-H2 reaction has shown no
need in the past for EM stimulation. In any case, the design limits
the frequency to a very narrow and presumably unproductive range. If
Rossi wanted to apply stimulation, he chose a very poor design,
which I doubt he would do if this stimulation were important.

Ed,
I think you forget to add the EM stimulation controlled by the black
box between wall socket and the eCat.

Fran, I would not guess how Rossi bonds the powder to the wall, only
that this must be done. A secret sauce is applied before the Ni is
placed in the e-Cat in order to create the NAE. You need to identify
how many additional secret sauces you think are involved. He also
places a hydride in the tube to supply hydrogen. This material also
might have an effect. I suggest speculation about things we have no
way of knowing is not productive. Let's discuss what is real and
required by nature for the observed effect to be produced.
We know Rossi activates the Ni before it is used, i.e. creates the
NAE.
We know this powder must make good thermal contact with the wall.
We know that Ni powder sinters at the temperature being produced.
We know that the NAE is stable at these temperatures.
We know that the generated power increases with increased
temperature. Therefore, a positive feedback is operating.
We know that Rossi attempts to control this feedback by controlling
the temperature.
We know that the power source responds rapidly to the external
temperature. Therefore, good thermal contact exists between the
source and the thermal sink.
We can suspect that no additional source of energy or stimulation is
applied to the power source other than temperature.
These are the only facts I can identify. Did I miss anything?

Ed,
you make a good case that something improves the thermal bond of the
powder to the inner walls.. perhaps the function of the secret
sauce.. I don’t recall the volume of the powder used but am under
the impression it fills most of the reactor tube and therefore must
also have good thermal bond through it’s own bulk to reach the
reactor walls. I think the MAHG was a weak easily compromised cousin
to this device with only a thin sputtered layer on the inner wall of
the tube while Rossi has designed a way to stack NAE out into a bulk
form away from the reactor wall. I gathered from the thread that
very little powder spilled out when they cut it open after
destruction… so would assume the bonding held the powder inside as a
foam or gelatinous solid? Can we assume the secret sauce must bind
the powder into some form of solid. I am leaning toward an open foam
like malted milk balls but a recent thread also suggested a
gelatinous colloid.

Bob, this is a good analysis of a possible design. You are right,
the powder must make good thermal contact with the wall for the
nuclear reaction to be controlled by temperature. Just how Rossi
makes this happen is unknown. Nevertheless, most of the active
nickel must be attached to the inner wall of the stainless tube. In
addition, at the temperatures used, the Ni powder would sinter and
not be easily to remove.
As for modifying the stainless using chemical etch, I doubt this
would be effective. This texture would have to be active initially
and remain unchanged at high temperature. Such textures are not
stable and would not survive the high temperature. Rossi has done
something to the Ni powder that is very stable and not affected by
high temperature. This fact alone greatly reduces the possibilities
to anyone familiar with the materials science of this material.
Rossi is gradually letting the cat out of the bag, whether he wants
to or not.

I would like to submit my speculation about the latest Rossi hotCat
for discussion on Vortex-l.
· We are told that the central reactor core is a 310
stainless steel cylinder ( 3cm by 33cm). There is no port for
introduction of H2. The ends are cold welded closed.
· When the test device was sawed open, only a miniscule
amount of powder came out. This cannot be the active powder - it
would have melted as loose powder rather than conveying the heat out
of the cylinder.
· It is highly desirable to have high thermal conductivity
between the NAEs and the outer metal cylinder. You wouldn't get
this with loose powder on the inside.
· 310 stainless is ~25% chromium, ~21% Ni, and the balance
mostly iron
Consider what Celani has done - taken a Ni-Cu alloy wire and etched
out the Cu to realize the surface nanotexturing, thus creating NAEs
on the wire outer surface. Suppose we took the 310 stainless
cylinder and used a chromium etch on the inner surface. Chrome
etches typically contain nitric acid which will also attack the
iron, but not the nickel. The result could be a nanotextured Ni
inner surface of the 310 SS cylinder with perhaps a micro-scale Ni
"fur" in high thermal contact with the cylinder. There may be
further chemical texturing of the inner surface or nanopowder added
as part of a thermo-chemical modification of the surface to create
the NAEs in high number on the inner textured Ni surface.
Then, cold weld one end of the cylinder closed. Calculate the
amount of metal hydride needed to release the desired pressure of H2
into the cylinder when it is heated and put this powder inside the
cylinder. Cold weld seal the second end closed. Viola! You have a
hotCat reactor core.
Rossi has also described his "cat and mouse" where the "mouse" was
added to enhance the performance of the hotCat. An easy speculation
for this would be that he could take some of his previous Rossi
micro-Ni + catalyst powder and add that as well to the hotCat as a
means to help the reaction begin from a lower temperature.
I believe the cylindrical outer heaters are just resistor coils
embedded in a high thermal conductivity ceramic.
