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.

The EM stimulation may not need to be at a high frequency level. 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.
