Re: [Vo]:The MFMP replication effort live on youtube.
Ryan cemented a type-B platinum thermocouple though the center of the plug. So he had actual data on the core temperature which got to about 1200C. The thermocouple at the surface only reported getting to about 850C at the same time. Parkhomov measured his temperature in between - on the outside of the reaction tube in the middle of the heater coil turns - not at the surface. Architecturally, if proton conduction and reaction with the heater coil ever proves to be a contributor to the excess heat, it could not be replicated in the dogbone. The dogbone has a small air gap between the reaction tube and the heater tube (and the heater coil is on the other side of the alumina heater tube), so any H that diffused through the reaction tube would become H2 or H2O and escape before ever making it to the dogbone heater wire. It wouldn't make any difference what the heater wire was in the dogbone - it is not designed to take advantage of that. For any possible reaction with the heater wire, the wire would have to be wrapped directly in contact with the reaction tube where the conducted H would escape directly onto wire. This is the way Parkhomov made his heater coil. A direct replication of Parkhomov would certainly included this. Such replications are underway, but will take some time to get the materials together. MFMP is asking questions to Parkhomov and I am looking forward to his answers.

Re: [Vo]:The MFMP replication effort live on youtube.
I think it's a valid point to check the inner alumina tube for leaks, which can probably be done by careful postmortem. Also I wonder if the alumina tube holding the Ni - LiAlH4 was sealed in a vacum. That would be the only other concern is if it was filled under a vacum, or pumped down is if the seal broke somehow (thermal expansion?) of the fuel cylinder and seal. As an alternative to the dog bone design and to rapidly test fuel mixture, I wonder how the alumina tube would do using microwave as the external heat source? That may help in LiAlH4 dehydrogenation process and Ni-H diffusion and would help make experimenting with fuel mix a little easier.

RE: [Vo]:The MFMP replication effort live on youtube.
From: Bob Higgins Ø The fact that the alumina is not 100% theoretically dense does not mean that the remainder is air/porosity. The remainder is a much lighter weight silicate glass in the grain boundaries The density of silicates is slightly lower than alumina - 2.65 compared to 3.95 but actual voids in the subnanometer geometry are necessary to get the density down to the 3.65 range. When we are talking about hydrogen permeability – and especially at high temperature, almost any porosity will allow substantial amounts of H2 gas to diffuse over time. It is all about the rate. Actually, it now appears that very slow diffusion can be a big advantage. Rossi apparently found that he could run a reactor for 30 days or so on about 10 milligrams of hydrogen which was introduced as a solid in AlLiH4 (1/10th of 1/10th gram). However, in analyzing the two reportedly successful reactors, the limiting factor does not seem to be hydrogen inventory, but instead it is nickel contact. The sub-gram of nickel is simply not enough since it cannot vaporize or expand in surface area. In fact the heat would tend to level and reduce any nano surface features. And based on comparing that amount of powder with the past 20 years of experiments in Ni-H, it is grossly insufficient. I keep returning to the Thermacore gas phase work for the Air Force as a standard of what can be expected. A sub-gram of nickel is too little… yet, if we have much more nickel available in the resistance wire, then the situation is different. We should not overlook that there is the modality of the SPP. If the light emission intensity were not so amazing in these dogbones, we could possibly overlook the SPP. But given that you have the interface of the Nichrome, with the ceramic, and the strong incandescent light - which is the breeding ground of surface plasmons, and then you also have the slow hydrogen migration out of the tube, it appears to me that this is the key to success, and correspondingly – the problem for the MFMP replication. I hope that this analysis is missing something, but if sealing the reactor does not work, then that will be further indication that there is more going on with the resistance wire and plasmons - than what is happening inside the tube. The bulk of heat may relate to SPP interacting with hydrogen so as to form either DDL, f/H or LENR. Take your pick. The DDL looks good to me based on the bumps in the noise which Parkhomov detected at a few key junctures. Jones
Re: [Vo]:The MFMP replication effort live on youtube.
I would agree with you completely if the cylinder were in direct contact with the water bath. But, it appears from the diagram that the water is located a distance from the cylinder and is not in direct contact. This configuration is a little like baking in an oven. The heat from the active device radiates, convects and undergoes a small amount of conduction as it finds its way to the surrounding water jacket. The water jacket can then radiate some energy back into the active cylinder to increase its temperature. Also, the elevated temperature air enclosed next to the device is trapped and heated as it attempts to convect heat away from the unit. The net effect of these two processes is to restrict the flow of heat originating within the cylinder. Increased thermal resistance at this point results in a greater thermal drop than would be seen had the device been able to operate into an open, low temperature environment. Perhaps it would be more apparent had another liquid been used besides water. The same thought experiment would seem true had we used a hypothetical liquid metal that boiled at 500 degrees C. How about one that boils at 1200 C? In either of these three cases I would expect the active device to get hotter than had it been subjected to open air cooling. The trend is the same.

The remainder is a much lighter weight silicate glass in the grain boundaries. The 96% grade has more silicates. Mullite is 1/3 silicates. Even mullite is not necessarily porous unless designed to be so. They can go back and etch out the silicates for specialty filters, but that is not what an as-fired ceramic tube would be. Residual proton conduction has to do with H-O reductions and exchanges in the grain boundary with metal/silicon oxide atoms. The bond for oxygen in sapphire is one of the best in all dielectrics - it really wants to hang onto its oxygen. That's why there is no proton conduction through sapphire. If there were really "pores" in the alumina, they wouldn't be proton conductor size - they would be gross leak size. At 100 bar, the H2 would be gone almost instantly.

From: Bob Higgins * CoorsTek is the major supplier of such alumina forms - they have been around forever in this market.

Their prices are typically significantly higher than ceramics from Asia and 998 is a pricey specialty material. * Alumina ceramics, in general, come in different grades varying from 96% to 99.8% but the tubes are not available in 96%, Yes they are. They come in grades as low as 92% ... maybe not from CoorsTek but that is apparently as far as you have looked. Plus - 96% is porous.

What I am calling porous alumina is sometimes sold by density… such as 3.65 g/cc. * In both the successful experiments, there was porous alumina BH: You have absolutely no basis for saying this. Based on available alumina tube materials, there is no "porous alumina". I would be just as easy for me to say that all alumina is porous, since even from Coors, the 100% grade is not available and 998 is ever so slightly porous. Perhaps there is no 96% from CoorsTek, but have you actually looked at anything beyond the one supplier? In fact, I suspect that most alumina is porous, in the sense of having density around 3.65. The 998 you have is a specialty material which is not commonly called “sintered alumina” as was both successful experiments.

I guess the reason is that LENR has always been considered a condensed matter reaction, not a gas or liquid phase reaction. The alumina is still solid, even if the Ni is not.

RE: [Vo]:The MFMP replication effort live on youtube.
From: Bob Higgins * JB: Then you are mistaken. The purity is immaterial – the porosity is everything. Of course, if MFMP used a fused tube then that is another design flaw. * BH: The tube MFMP used is a high purity, high (near theoretical) density alumina tube Well, there you have it ! You have made clear that there a second part of the problem – and another intrinsic design flaw. There is no scientific reason to make these kinds of major changes in a successful experiment, and then to defend them to the point of irrationality, when the positive results did not happen. The tubes of Rossi and Parkhomov are sintered alumina. Sintered alumina has just enough porosity -- 7-8% to allow proton diffusion. The experimenters may not have chosen porous tubes for that exact reason, but that doesn’t matter in the end. Why they chose sintered alumina is not important - since it works. Nor does it matter where --- in the reactor --- the experimenter “thought” the reaction was occurring, unless there is proof that the experimenter really understands what is going on. No one understands this reaction, as best I can tell – so in any replication, the main thing that can be done is to duplicate. The MFMP did not duplicate. It does little to try to defend these changes “logically”, since the end result was a null experiment. Maybe the next run will be positive, but as of now, it appears that the changes which are at variance to the successful runs - are the crux of the problem. In both the successful experiments, there was porous alumina together with nickel-based resistance wire. In the unsuccessful MFMP reaction the was non-porous alumina and there was no nickel in the resistance wire. It does not take a genius to understand that these two differences could be responsible for the lack of success since we have 20 years of papers to use to help in an analysis. We know the gainful Ni-H reaction is proved – going back to Thermacore, and that it requires hydrogen in contact with nickel – lots of nickel. For the Thermacore gas phase experiment, they used hundreds of feet of nickel capillary tube to get 50 excess watts. It is incomprehensible to think that far less nickel will give far more excess heat, simply by raising the temperature. Bottom line: the sub-gram of nickel fuel is NOT sufficient in my opinion, and based on past experiments which did produce gain. And yes – this is my opinion and you can and will ignore it. But I would be remiss in not putting it forward and trying to emphasize how much stronger the scientific logic is - than to say basically “we made major changes, got null results, but the changes we made are defensible.” Jones
Re: [Vo]:The MFMP replication effort live on youtube.
Jed, The setup used by MFMP uses the surrounding room temperature as the sink for heat generated within their device. That should appear cooler to the actual heat generating device than a water cooled metal container which is at approximately 100 C. I would also believe that convection currents would be more effective in open air rather than confined to a constant 100 degree temperature enclosure. I am assuming that there is little direct conduction between the active device and the metal container in Parkhomov's experiment. Are you aware of any attempt to conduct heat directly away?

The only possibility for the wire to be involved would mean that there is proton conduction through the alumina tube and that somehow any conducted H doesn't all combine with the readily available oxygen existing at the wire. At that temperature, the wire and the silicates in the alumina cement are constantly releasing oxygen and then chemically re-combining with it in a cycle. The small amount of conducted H2 would instantly burn before it could provide any useful LENR effects at the wire. >From Bob Grenyer's excellent research in heater technologies for the market that Rossi is trying to serve with his hotCat, and from the sequencing of the power carefully in the heat-up portion of the cycle in the Lugano test, and from the temperatures that the hotCat operated at in the Lugano test, either moly silicide or SiC were the likely heating elements being used. Nichrome is too low temperature. Inconel is too low temperature as a heating element but could have been part of the heater leads. Rossi stated a negative temperature coefficient for the heater and it fits with the other evidence for the heater type (neither nichrome or inconel have significant resistance variation with temperature). Where is your evidence that Rossi used a nickel alloy heater wire? Ø I also don't believe that the H2 just comes out through the 99.8% > high purity alumina reactor tube. > > Then you are mistaken.

Sapphire is not a proton conductor, so the sapphire crystallites don't conduct. Proton conduction in alumina comes via the grain boundaries and the glassy impurities found in the grain boundaries, usually silicates. So the tube MFMP used would have the smallest proton conduction of any available alumina - save sapphire. Parkhomov used an alumina tube of unspecified purity. Parkhomov believed that the reaction was taking place inside the tube, not at the heater. This is somewhat supported in his experiment by the fact that LENR continued in self-sustaining mode for 8 minutes after the heater had burned out. During that time, the conditions at the wire changed significantly, yet the LENR persisted. Even a "high alumina" cement coating that is used to coat over the heater coil is only about 85% alumina and the rest is various other metal oxide glasses depending on the manufacturer's formulation. The result is not dense and will breathe air at a non-negligible rate providing O2 at the wire.

With the technology developed for making the dogbones, there is nothing to prevent Ryan from winding one with nichrome wire and one with inconel. At this point, none of the MFMP contributors believe that the wire type is a factor in success or failure. If we are unsuccessful in replication, having determined that we don't have a leak, we could still try changing the wire; it is just not in the current priority based on the group opinion.

I agree that 0.9g of Ni sounds like a small amount, but if it were 9g of Ni, that would be only 1 order of magnitude different power density (and you wouldn't be making that argument if it were 9g) and the variation that is seen in Ni-H LENR power density reports varies by many orders of magnitude.

Bob-- Seal under inert gas pressure--100 bar if necessary. That should keep the H2 in with only diffusion gradient acting to let the H2 out.

It's very difficult to make this type of seal. When the cement is wet, the hydrogen easily passes through. I use a dangerous gas detector as I heat it up, but as yet, have not achieved a seal in experiments I've tried.
