ABSTRACT

 In this paper, the author describes the fundamental requirements to induce Cold Fusion or Low Energy Nuclear Reactions (LENR) inside of the crystal lattice structure of metals capable of absorbing hydrogen – such as nickel, palladium, platinum, titanium, and titanium. Practical considerations are provided for the preparation of powders (particularly nickel) in such a manner to allow for high levels of hydrogen loading. Furthermore, stimulation processes are discussed and how they relate to various methods of inducing the exit of hydrogen from the nickel lattice beyond the rate at which hydrogen may desorb. A unified concept is presented that provides a logical framework to guide replicators as they work towards reproducing the, “Rossi Effect.”

INTRODUCTION

Since the emergence of Andrea Rossi’s E-Cat (Energy Catalyzer) in 2010, there has been a greater level of interest in the field of Cold Fusion or Low Energy Nuclear Reactions. The various versions and implementations of his technology have demonstrated enormous energy and power densities (sometimes up to or beyond 1000 w/gram of fuel mixture) that have excited the imagination. Such high power densities at high temperatures of beyond 1300C without the expected accompanying levels of ionizing radiation (gamma, neutrons) offer the potential of a radical new energy source capable of changing our civilization in fundamental ways – away from the use of hydrocarbons or traditional fission based nuclear power.

Tempering the hope of utilizing this technology for the betterment of mankind, has been the high failure rate of replication attempts. Although a number of highly successful replications seem to have been performed (Songsheng, Parkhomov, Stepanov, and others), most tests yield little to no excess heat. The reasons for the lack anomalous thermal events has been unclear.

From analysis of available documentation in the form of patent documents, third party  replications, discussions with successful replicators, and the vast wealth of literature available, the author has conceptualized a framework of logically deduced guidelines that may hold the potential to increase the success rate dramatically. Primarily, the guidelines revolve around two critical issues that must be broken down into additional topics and analyzed: the absorption of hydrogen into a transition metal allowing for the creation of a highly loaded “metal hydride” and the stimulation of said metal and hydrogen via thermal shock and/or additional methods.

Successfully achieving hydrogen loading and a sufficiently powerful thermal shock – inducing the desorption or degassing of the hydrogen from the nickel at a rate that is faster than possible by the constraints of the lattice – are the two absolutely critical requirements for inducing “cold fusion” in metal hydrides. However, to achieve such loading and stimulation careful choices of fuel composition and fuel preparation must be made. This paper discusses such issues and others vital to the successful replication of the Rossi Effect.

 

Transition Metal Choice and Additives

Early Cold Fusion experiments from the late 1980’s to the 1990’s often utilized palladium which has  is an especially good at absorbing hydrogen, reaching possible loading ratios up to one atom of hydrogen to one atom of metal. During the same time period and afterwards, a number of other metals and alloys were tested. Although these were primarily electrolytic systems – far different than Andrea Rossi’s present day gas loaded systems – the most important factor in the production of excess heat were identical: the absorption of hydrogen into the metal lattice. The work of Sergio Focardi, Francesco Piantelli, and others led to the development of the first gas phase nickel-hydrogen systems.

These experiments obviously were the basis of what inspired Andrea Rossi in the development of his E-Cat: the use of a hydrogen gas environment instead of a liquid electrolyte allowed for higher temperatures to be achieved, the use of nickel allowed for massive cost savings that could yield a commercially viable system, and the various methods of stimulation performed allowed for the precise control of the exothermic nuclear reactions produced.

Although poorer at absorbing hydrogen than palladium, nickel continued to be his primary transition metal, although documents and statements indicate that his earliest reactors (such as those tested in 2008 before opening the Journal of Nuclear Physics) utilized mixed powders containing both copper and palladium –something possibly implied by a statement from Tom Darden in an interview with Fortune Magazine. This has the purpose of enhancing the absorption of hydrogen into the nickel via the “spillover” effect. These early systems, although fairly low temperature compared to later “hot cat” reactors, seem to have been capable of very high COPs into the hundreds.

The first public and third party E-Cat reactors tested after the opening of the JONP seem to have moved away from the use palladium as a fuel additive, according to analysis of spent fuel. Although copper powder may have continued to have been used for a period of time, its presence in spent “ash” from these later reactors could be due to electro-chemical migration from copper components (such as reactor bodies) or physical abrasion from manually scraping to remove used fuel.

Although largely ignored early on by online commentators, bloggers, and replicators, lithium was found as an additive in these early systems. Originally, lithium is conjectured to have been added in elemental form; however, the “Fluid Heater” patent granted to Andrea Rossi specifies that LiAlH4 started to be used in addition to elemental lithium powder. An electro-positive element that can serve as a promoter for hydrogenation, lithium had the dual purpose of both helping facilitate the absorption of hydrogen and acting as a fuel via a number of possible nuclear reactions, including the nuclear reaction between a proton and lithium atom resulting in two alpha particles.

The function as an electropositive alkali metal promoter is opposite of the electronegative catalytic poisons that hinder hydrogen absorption such as chlorine and sulphur. The second function of lithium as a fuel is built upon the foundation established by Hidetsugu Ikegami whose extensive testing revealed an enormous nuclear rate increase between protons and lithium in the molten state. Furthermore, the testing performed by Unified Gravity Corporation on the low energy fusion of protons and lithium, with an optimum energy sweet spot of around 200eV compared to the 300,000eV minimum that conventional scientific understanding demands, confirms the uniqueness of lithium as nuclear fuel.

Seemingly high successful replications of the Rossi Effect achieved by Songsheng Jiang, Alexander Parkhomov, N. Stepanov, and multiple other individuals and teams confirm that massive excess heat can be produced by utilizing nickel powder, lithium aluminum hydride (LiAlH4), and no other additives except what contaminants may reside in the fuel or maybe leeched from the reactor body. These contaminants may effect, positively or negatively, the production of excess heat but are in no way critical to a successful replication. To avoid excessive complexity, the primary focus of this paper will be on the utilization of nickel powder and lithium aluminum hydride alone – with the possible addition of elemental lithium or LiH (lithium hydride) to enhance the pressure dynamics of the reactor. However, for those who may seek to replicate Rossi’s earliest systems which utilized an external hydrogen tank as a source for hydrogen, the addition of palladium and/or copper powder may be a plausible route to enhance hydrogen absorption.

The nickel selected for a replication attempt should be of fairly small particle size between a few microns and a few tens of microns. A number of different nickel powder types (nickel shavings, high surface area carbonyl nickel, electrolytic, and others) have been successfully utilized. Although the grain structure, surface area, and morphology of the nickel may have significant effects on hydrogen absorption and the production of excess heat, they do not seem to be critical – as will be discussed in another section of this paper the cleanliness of the nickel surface and interior lattice structure seem to be of upmost importance.

The choice of LiAlH4 is also important, due to the fact that not all brands are equal in hydrogen content, level of contaminants, and particle size. More than one successful replicators have reference the efficacy of Alfa Aesar brand LiAlH4 of 97% purity. This may be due to the smaller particle size of around 10 microns verses 50-150 microns for Sigma Aldrich sourced LiAlH4. The smaller particle size, possibly produced by high energy ball milling, may help facilitate more efficient desorption of hydrogen. Also, although officially rated at 97% purity, the certificate of analysis of some batches of LiAlH4 from Alfa Aesar indicate a level of 99% purity. This may reduce the level of catalytic poisons known to be present in LiAlH4 such as chlorine.

 

Nickel Surface Cleaning

The surface of most commercially available nickel powder is covered in an oxide film (NiO) that inhibits the adsorption of hydrogen, the first step in the process that leads to the absorption of atomic hydrogen into the lattice of the nickel or other transition metal. The nickel oxide film can be removed via a number of methods, each of which come with their own benefits and drawbacks.

Ultrasonic irradiation of nickel powder in an alkane hydrocarbon slurry (hexane or decane as examples) utilizing a low frequency range of around 20khz at a high intensity of 50 watts per cubic centimeter has proven to completely remove the surface film off nickel, allowing for a massive increase in catalytic ability.

In a liquid medium, ultrasound produces cavitation bubbles that oscillate and grow before experiencing a powerful rapid collapse which yields extremely high temperatures of thousands of degrees Celsius and pressures of hundreds or thousands of bars. If an object with a surface area significantly larger than the diameter of the cavitation bubble is nearby, the central “hot spot” inside the bubble can deform asymmetrically and produce a powerful jet that can impact the particle. This can induce melting, pitting, fragmentation, and chemical reactions. The bubble size produced by ultrasound is proportional to the frequency. A frequency of 20khz results in a bubble of approximately 160 microns in diameter, which is far larger than the typical nickel particles used in Rossi Effect replication attempts. In this case, since the surface area of the particle is smaller, the jet does not form. Instead, the shockwave from the collapsing bubble imparts kinetic energy to the nickel particle accelerating it up to half the speed of sound. The power of the bubble collapse, resulting shockwave, and kinetic energy is a function of a number of factors: the viscosity of the liquid (lower means faster movement of the particle), the vapor pressure of the liquid undergoing cavitation (the lower vapor pressure the more powerfully the bubble collapses), the frequency of the ultrasound (lower means a more powerful collapse), and the intensity of the ultrasound.

The collision of nickel particles removes the outer oxide layer and smooths the surface, enhancing the ability to adsorb hydrogen and act as a catalyst in chemical hydrogenation reactions. The catalytic activity of nickel in such reactions have been increased up to 100,000% in certain tests. Extensive ultrasonic irradiation over a longer period (beyond one hour at 50 watts per cc) can reduce the catalytic activity.

Interestingly, a thin layer of carbon is applied to a portion of the surface of the nickel by this process. This carbon is thought to be sourced from the thermolytic breakdown of the hydrocarbon alkane by the high temperatures produced inside the bubbles. Various authors speculate this carbon may actually enhance the catalytic properties of the nickel beyond just the removal of the oxide layer. One reason for this could possibly be the production of imperfect, fragmented carbon allotropes such as graphene or carbon nanotubes on the nickel surface. One commercial process of graphene production involves the application of carbon onto a nickel surface and irradiation with ultrasound.

If this method of nickel surface cleaning is utilized, great care should be undertaken due to the toxicity and flammability of the alkanes mentioned. Hexane, for example, is neurotoxic and a possible carcinogen.

A more traditional method used to remove nickel oxide is the use of hydrochloric acid, acetic acid, or others diluted in various ratios. These methods combined with stirring can chemically etch away the oxide layer. Acids such as hydrochloric acid, that contain chlorine, an electronegative catalytic poison, should be avoided.

Yet another method is the reduction of nickel oxide by a flow of hydrogen at high temperatures. At very high temperatures 700C or higher the oxide layer can be completely removed in seconds to minutes. At lower temperatures, the process may take longer and can often be incomplete, leaving residual oxide. In addition to temperature, the flow rate of hydrogen also influences the reduction speed.

One or more of these processes should be performed to clean the surface of the nickel before any attempt at hydrogenation. Although in-situ reduction of the nickel oxide layer by hydrogen may take place inside an active reactor, the degree of elimination may be variable. At very high temperatures molten lithium and aluminum may chemically remove the oxide layer, but depending on these processes is a gamble that is not worth risking days or weeks of labor spent in the laboratory. Also, exposure of the cleaned nickel surface to atmosphere can result in the re-growth of the oxide layer in a short period of time – possibly minutes. Keep the cleaned nickel in an inert environment, preferably hydrogen.

 

Nickel Interior Cleaning – Degassing

Removing trapped gases and contaminants from the interior of the nickel powder is equally as eliminating it from the exterior surface. Trapped gases take up free space in micro-cavities, cracks, defects, and interstitial spots where atomic hydrogen will need to go during hydrogenation/loading. If these gases are not removed, a lesser quantity of hydrogen will be absorbed potentially resulting in a lack of excess heat production.

The vacuuming of nickel under heating is the accepted means of removing these contaminants. Keeping in mind the possibility of sintering together the nickel particles (their surfaces previously cleaned of oxides), high temperatures should be applied along with low vacuum pressures. This process should continue for hours, days, or even up to a week to remove all trapped gases. To maximize removal, a step wise increase in temperature should take place. At a certain temperature the exodus of trapped gases will flat line; however, increasing the temperature will re-start the desorption process.

Multiple successful replicators have utilized a degassing stage in the processing of their fuel – either in a separate vessel or in the active reactor. One example is Songsheng Jiang who vacuumed his nickel-LiAlH4 fuel mixture for up to a day, without the application of heat, before starting one of his highly successful tests that produced the “heat after death” effect. In this case the application of heat to the LiAlH4 would have resulted in the early release of hydrogen. Christos Stremmenos and an unpublished account by Thermocore have told of massive exothermic releases of energy produced after nickel had been exposed to high vacuum for extended periods. Andrea Rossi is also said to have utilized a vacuum pump for in-situ removal contaminants in some of his early tests. There also exists a high probability he may utilize degassing as a step in the preparation of the fuel for his newer high temperature reactors.

Simply put, skipping the degassing stage will reduce the chances of producing excess heat. Serious replicators should utilize this process to maximize hydrogen absorption. As with nickel surface cleaning, do not allow the nickel to have contact with atmosphere after degassing or absorption of atmospheric gases may take place.

 

Pre-Loading of Hydrogen

Nuclear reactions cannot take place if hydrogen is not loaded into the lattice of a metal hydride. This can take place during the heating stages of an active reactor, regardless if fueled by an external tank or LiAlH4. However, performing multiple pre-loading or pre-hydrogenation sequences on the transition metal powder may better your chances at producing excess heat by augmenting what will be absorbed during the actual run.

To accomplish this, the nickel powder should be placed in appropriate vessel which has been cleaned via degassing with vacuum and application of hydrogen. Once the powder, for this example nickel, is placed in the vessel, the highest available and safe level of hydrogen pressure should be applied. The vessel should be heated to a minimum of between 150-200C or higher during this process. The rate of hydrogen absorption is controlled by both of these variables: heat and pressure.

If one is available, a high precision manometer should be utilized to monitor the hydrogen pressure in the reactor. One method of determining the rate of hydrogen absorption is to watch for a pressure drop. When the pressure slowly drops over time – which can take hours, days, or longer – and eventually flatlines, additional hydrogen should be added to increase the pressure back to the original level. After repeating this process multiple times, the amount of hydrogen absorbed each cycle will decrease.

If someone wishes to push pre-hydrogenation to an even higher rate, an atomic hydrogen source can be used. The atomic hydrogen will absorb much faster into the nickel than would molecular hydrogen, because the dissociation step – the rate limiting step in hydrogen absorption – is bypassed.

After the hydrogen absorption process is complete, the nickel should be allowed to cool in a hydrogen environment. The hydrogen that was absorbed will be locked inside the lattice of the cooled nickel, and will not desorb significantly unless further heat is applied.

 

Slow Heating Of Active Reactor

If LiAlH4 is used as a hydrogen source mixed in with the nickel powder, the reactor should be heated very slowly at a rate of below one degree K per minute through 200C. By heating at such a slow rate, the LiAlH4 does not melt, phase change into a liquid, and wet the nickel (hindering hydrogen absorption) before decomposing. After 200C, the reactor should be heated to 700C at a rate no faster than 5 degrees Celsius per minute.

If an external source of hydrogen is available from a hydrogen generator or tank, supplemental hydrogen should be added during the slow temperature climb to 700C (in preparation of a thermal shocking or triggering attempt). Adding supplemental hydrogen in addition to what is provided by the decomposition of LiAlH4 will fulfill the findings of Sergio Focardi and others that multiple cycles of increased hydrogen pressure are optimal for hydrogen absorption.

 

Preparation for Thermal Shock Event

In a system utilizing LiAlH4, at the temperature of around 700C or little higher, LiH (lithium hydride) should start to decompose. This will result in a pressure increase that can drive more hydrogen into the nickel lattice. After a period of time the temperature of the reactor should be reduced down to a lower temperature – perhaps 400C or 500C. As the temperature drops, two processes will take place: additional hydrogen will be absorbed into the nickel and gaseous hydrogen will react with elemental lithium to form LiH. This should reduce the internal pressure of the reactor.

The next step will be to rapidly increase the temperature of the nickel beyond a critical level. Basically, we want to induce the atomic hydrogen to desorb from the nickel at a rate faster than is physically possible. This will result in a very high pressure build up in the voids, cracks, cavities, defects, and interstitial sites. One patent application indicates that the pressure inside the nickel could reach up to 100,000PSI in a titanium lattice, due to the high tensile strength of the material. If the pressure reaches an adequate level, the result should be nuclear reactions of various kinds that will produce an output far beyond any chemical process. The author speculates that the maximum strength and intensity of the nuclear process may be a function of the tensile strength and other properties of the metal. For example, weaker exothermic events in aluminum, compared to nickel, may be the result of a reduce tensile strength.

In this example, a sudden drive upwards to 700C may be sufficient to trigger nuclear reactions, but a number of other methods may also work. For example, Andrea Rossi’s original Italian patent application describes a system that rapidly varies the pressure in his reactor up or down (this is when he was using an external hydrogen tank). This was mentioned as a method of stimulating reactions. Considering that lowering the pressure could provide a suction that could increase pressure inside of the nickel, this makes perfect sense. Furthermore, Sergio Focardi and Francesco Piantelli reported being able to trigger excess heat events by dropping the pressure in their systems in a rapid manner.

If the nickel in a reactor has been highly loaded with hydrogen, it may be useful to use a vacuum to lower the pressure before rapid heating takes place. The two forces – heat trying to push the hydrogen out of the nickel and vacuum trying to pull it out – may combine to stress the nickel to a high level. This could result in a greater chance of exothermic nuclear reactions.

The process of repeated absorption and desorption of hydrogen can alter the internal structure of the nickel, producing cracks, fissures, and defects that may allow for additional hydrogen to be absorbed. If one triggering attempt does not produce excess heat, repeated cycles above and below 700C may eventually allow for enough hydrogen to be absorbed to induce nuclear reactions.

 

Electromagnetic Stimulation

Since the very first public tests of E-Cat devices, it has been speculated that Andrea Rossi utilizes specific frequencies to further stimulate nuclear reactions. He calls this, “the drive.” The drive can come in a number of forms, but primarily it is expected to be the use of high voltage three phase “dirty” AC power to the resistor coils. The electromagnetic fields generated may allow for nuclear reactions to be induced with less input power.

Songsheng Jiang’s test system utilized a design in which a significant thermal barrier existed between the electrical resistors of his device and the innermost reactor. Significant insulation existed between them, including a thick metal barrier composed of steel and empty free space. Utilizing multiple thermocouples, at the onset of turning on the input power he was able to detect an upward surge in temperature of the reactor core before thermal energy would have had time to migrate from the resistors. This proves that if the fuel is already heated to a certain temperature range, it can be stimulated electromagnetically without the addition of heat. This may be the result of the magnetic field remotely heating the nickel lattice via magnetic induction. Or it could be the interaction between the magnetic or electric field and an exotic hydrogen species created by the high pressures deep in the nickel lattice.

An additional method of stimulation may be the application of electrodes on either side of the reactor body to induce a voltage across the fuel charge of the reactor. This method, mentioned briefly in one of Andrea Rossi’s patent applications, was attempted to be utilized in a “gas cat” that utilized natural gas for a thermal drive rather than electricity. We now know that Rossi abandoned that line of development due to him optimizing his electromagnetic stimulation method.

 

High Temperature Work

There is no guarantee that even after utilizing all of the concepts mentioned in this paper that you will be able to trigger anomalous excess heat at low temperatures. Both Songsheng Jiang and Alexander Parkhomov required very high temperatures exceeding 1000C to produce significant results. One reason speculated as to why such high temperatures may sometimes be needed is that the vaporization of lithium may be important to the Rossi Effect. At atmospheric pressure, lithium does not completely vaporize until over 1300C. However, some vaporization can take place at lower temperatures – especially if the pressure is reduced.

In preparation for high temperature work, make sure you are utilizing an inner reactor tube that is resistant to the corrosive effects of lithium at high temperature. This would mean stainless steel or iron. Lithium at such temperatures can eat right through aluminum oxide and many other materials.

Additionally, try to minimize the oxidation of your heating elements at high temperature. A commonly used heating element, Kanthal A1, oxidizes quickly at such high temperatures and may have a shortened life – especially when rapidly cycled up and down in temperature. Either use an alternate heating element material or insulate the resistor from atmosphere with a ceramic coating.

 

Additional Ideas and Concepts

The basic setup and fuels needed for an E-Cat replication are fairly simple and straightforward. A combination of properly prepared nickel and LiAlH4 stimulated appropriately appears capable of producing high levels of anomalous excess heat from a nuclear origin. However, the author would like to provide a few additional thoughts about more exotic or elaborate concepts that could yield interesting results.

  • Ultrasonically irradiating a mixture of nickel, copper, and palladium powder in hexane or decane could produce a fuel mix that may optimize the absorpton of hydrogen into the nickel. Palladium’s superior ability to adsorb and absorb hydrogen may allow the spillover effect to induce a high loading of hydrogen in nickel. An example could be using a larger nickel powder size (lets say 20 microns) and a smaller palladium powder size (1-2 microns). The palladium could pepper the surface of the nickel powder like shotgun pellets. Instead of simply being mixed together, the palladium could be physically embedded into the nickel.
  • The use of an extremely hot tungsten filament in the pre-hydrogenation vessel or even the active reactor could increase hydrogen loading dramatically. At approximately 2,000C a tungsten filament will start to produce atomic hydrogen which will be absorbed into the nickel or other transition metals at a high rate. The hydrogen could also be applied to the reactor through a thin tungsten tube heated to such a temperature.
  • Applying an electrostatic charge to nickel can have a significant effect on hydrogen absorption. This should be further researched and experimented with.
  • A spark discharge can generate atomic hydrogen. Generating such discharges in the hydrogen environment during pre-hydrogenation could yield greater levels of absorption.
  • Nuclear reactions can be induced only with heat. Direct current seems to be suitable for this purpose. For example, Songsheng induced many hours of self-sustained operation using only direct current. However, in addition to testing out high voltage (300-400 volts or higher) three phase “dirty” AC, even higher intensity square waves should be tested. These square waves should have the shortest rise time possible to have the most powerful impulsive effects including the emission of longitudinal electromagnetic waves.

 

Conclusion

The basic guidelines to follow when attempting to replicate are fairly simple and straightforward. Conversely, the chemical, electrical, and material science issues are not. Experts in varying fields should cooperate and work together to come up with solutions to various issues. Even with a great deal of effort, the results of any replication attempt can be hit and miss until experience in the art is gained. However, the result of achieving anomalous heat production would be worth all the time and effort

 

A Note On Co-operation

High powered LENR technology holds the potential to change our world in a number of different ways, allowing for a revolution in almost every industry. From environmental solutions to a way to power space craft to colonize our solar system, the “Rossi Effect” is a game changer. If you have success replicating, please share your results openly and assist others in reproducing what you have achieved. Now is not the time for secrecy. For this technology to have the maximum impact and emerge in a manner that keeps it out of the hands of those who would attempt to control or potentially monopolize it, the knowledge to demonstrate the potential of this technology must be openly disseminated.

    The preparation of LENR fuel is a two step process where the first step produces the metalized hydride made possible by following the guidelines of BEC production listed above.

    Step 1

    In this fuel preparation stage only BEC enabling fuel components are used. This means pure lithium 7. Clean nickel that is highly porous is required to produce the metalized hydrides.

    Step 2
    The second step of fuel usage is to provide lithium as fuel to the LENR process so that NO additional metabolized lithium hydrides is produced to avoid reactor meltdown. In this stage, lithium aluminum hydride is used because lithium 6 and aluminum 27 are BEC poisons which dampens the LENR reaction. This dampening removes the danger of reactor meltdown.

    Note that Fluorine is a BEC friendly element. Fluorine 19 has 9 protons and 10 neutron and 9 electrons: a BEC count of 28 which is even and therefore BEC capable. This means that lithium 7 fluoride is acceptable to use in step one of the fuel preparation process.

    Nitrogen 14 is a LENR poison. Can you workout why? hint: 14 + 7 is odd.

  • Axil Axil

    Li-6 is used in thermonuclear weapons and the export and use of Li-6 is therefore strictly controlled. Rossi’s patent requires the use of lithium as fuel with the conversion of Lithium 7 to Lithium 6. The Nuclear Retaliatory Commission(NRC) will place any device that uses lithium as fuel where lithium 6 isotopic ratio is enhanced over nature levels is in violation of NRC regulations and will be restricted as a thermonuclear weapons proliferation risk. The NRC will not permit a commercial product that produces nearly pure Lithium 6 to be freely available for use in the marketplace were Lithium 6 can be extracted from it.

    LENR developers must stay away from any LENR reaction that uses lithium as a fuel.

  • Axil Axil

    ​I have just authored a post explaining how Bose condinsation is central to the LENR reaction.

    In order to get the Bose condinsate to form, the gas that enters the lattice must be pure in the expreme, all gas atoms must be the same. This means that all the surface imperfections must be cleansed of all dissimilar gas types. Air, oxygen, water vapor, nitrogen…every possible gas contamination must be removed from the gas pockets in the lattice.

    The hydrogen isotope used in the LENR reaction must also be absolutely pure. There must be no mixing of protium, deuterium and tritium. The hydrogen isotope must be 100% pure.

    This is a hard requirement to meet because the source of the hydrogen can be a hydride that was chemically constituted using a mixed hydrogen isotope.

    This means that the replicator must make his own hydride using a isotopically pure hydrogen source.

    • RobW

      Axil, what happens when bose condensate is stimulated by pulsing electromagnetic fields? I would expect eddy currents would occur without ohmic losses due to the superconductive nature of bose condensate. Due to the lack of resistance such currents could be large. If in such state cracks would occur a few things happen: some local eddy currents will be interrupted and bose einstein areas will disappear or re-locate. This will cause local heating amongst other effects.

    • Alan Smith

      Hi Axil. The theory you espouse is both good and interesting. However, there is absolutely zero evidence that Rossi has ever used ultra-pure Hydrogen/Hydrides as you claim. Numerous photographs from Bondeno/Ferrara show that he used commercial Hydrogen tanks, and at least while in Italy never synthesized his own Hydrides but used those sold by Alfa-Aesar. He was also very casual about aspects of reactor loading and so on, sometimes starting them up with still damp alumina cement seals.
      It is, I suppose, possible that in order to create something like the Q-X one might need to use isotopically pure materials, but I am pretty sure the common street Tabby version of the E-Cat never did.

        If memory serves, Piantelli stated that deuterium was a poison to the Ni/H reaction and he uses deuterium to kill runaway LENR reactors.

        Early on, Rossi did the same runaway reaction killing function with nitrogen.

        from

        news.newenergytimes.net/2011/0…with-credit-to-piantelli/

        “Piantelli has an exciting story to tell of another experiment that, for few hours, was out of control. It was sometime around September 1993, before Piantelli-Focardi group’s first published paper on the subject. Around 7 in the evening, he looked at the monitor for the experiment. Something didn’t look right. The temperature was increasing rapidly. He wasn’t sure what to do. Should he kill the experiment, and if so, how would he stop it?

        A rapidly increasing temperature in an enclosed steel container could be a big, big problem. He was afraid. He wondered whether he should leave the building. Instead he called Focardi in Milano—at 2 in the morning—and asked, “What should I do?” This was before Piantelli knew about the poisoning effect of deuterium. But Focardi came up with a workable idea: introduce nitrogen. And it worked. It stopped the uncontrolled temperature rise and killed the experiment.

        Piantelli didn’t know how hot the experiment had gotten before he killed it because the monitor eventually blacked out. However, the metal thermocouples inside the cell melted. This told him that the temperature exceeded 1450 C. Understandably, he was angry because these experiments take a long time to run and he had to abandon it prematurely.

        “It’s not good when they run too hot,” Piantelli said. “400 C is a much better range.”

        We might ask ourselves, if too much deuterium can stop a reactor meltdown, then a certain percentage would produce stable reactor operation. The more basic question is what fundamental physics principle produces isotopic reaction poisoning. There are parameters that control fuel performance and a reductionist scientific experimental exploration of this issue might provide answers.

        Such experimental Insight provided by these types of experiments will also help select the proper hydride fuel storage medium and the nature of the metal powder surfacing.

      I agree with you in general, but I disagree with you on the specifics.

      There is no evidence that all the gases have to be pure, “to the extreme.” There is a lot of evidence that excess heat can be generated, occasionally, even in very sloppy setups where rates of atmospheric contamination are high.

      However, to maximize hydrogen absorption, everything should be as pure as possible.

      – All oxides should be removed from the surface of the nickel.
      – All interior gases should be removed from the nickel via vacuum.
      – The LiAlH4 should be of the highest purity possible and of a small particle size to maximize hydrogen release and to reduce the quantities of electronegative hydrogenation poisons such as chlorine.
      – After all pre-processing has been completed, the fuel should NOT be exposed to anything other than a hydrogen atmosphere.

      Hydrogen loading is the most critical factor. If you don’t have adequate hydrogen inside of the lattice then “shocking” the fuel won’t produce excess heat. If you do have enough loading, then advanced forms of stimulation (rapid three phase high voltage AC) is not required to show a robust effect. Cures reported that the first hot cats produced massive excess heat leading to runaways repeatedly — and they were stimulated only with direct current.

      Once we achieve the basic Rossi Effect (hours of self sustain with power densities in excess of 1000 watts per gram of fuel) then we can proceed with optimizing the effect further by the various methods you suggest.

        Hank – shocking a highly-loaded Hydride is likely to produce both fusion and neutrons. See US patent application 20150221405 from the University of Missouri with Mark Prelas as the inventor of record. This therefore wouldn’t be LENR but a somewhat cold version of hot fusion. You’d also get gammas and transmutation, of course. Since there is quite a bit of confirmation of this effect from other sources, I’d rate the UM patent as reliable, but in turn this limits what you can do with the heavily-loaded hydrides and avoid it happening.

        I’d agree with Alan that it appears that Rossi loaded his fuels in air and was not concerned with purity of the reactants.

  • Simon Derricutt

    Hank – this is an excellent exploration of various ideas, so please don’t take this as a criticism of your work. Over the years, we’ve seen problems in the way Rossi has measured his heat and the Doral test has produced some unanswerable questions of where the heat went if it was indeed produced. If around 1MW went into that closed room, then it must also have exited (conservation of energy) and it seems that an IR survey of it (by IH) could only account for around 20kW. As far as I can tell, JM Products did not actually produce any product (no movements of raw materials or finished product seen) and didn’t employ any staff to work there. Though IH produced the reactors for Rossi’s use and tested them, they did not see excess heat from those that they operated. There is still the court case running and we may or may not get the scientific proofs we want from that, but at this moment it seems to me that it is extremely unlikely that the Doral test produced any significant excess heat.

    It is however reasonable to accept the work of Piantelli, Focardi, Parkhomov and others as being honest and to try to work out why they worked and how to make them work better. As regards the Tungsten use, there is the original Langmuir work on excess heat which assigned it to a disparity between the dissociation/association work from atomic to molecular Hydrogen. Different experiments by Langmuir ended up with different values for this excess heat, and the effects seen could be explained more easily as LENR (sometimes works, sometimes doesn’t) than by ZPE or breaking CoE.

    With LENR we have a lot of pieces of a jigsaw puzzle we need to fit together to get the whole picture. It seems to me though that what comes from Rossi is a different picture, and trying to fit them in to the real LENR puzzle will delay the solution. I think Mills and Holmlid are valid parts of the puzzle, though, even though some of the claims may be wrong. Brillouin do seem to have produced in the region of 10-20W from their experiments, and this seems more believable – not as dramatic as Rossi’s claims but certainly indicative that there is the possibility of achieving higher outputs. It’s also worth considering Stringham’s use of cavitation in Pd/D and thus that other ways of getting the trigger energy in may be helpful.

    Given that Rossi used ideas from Piantelli and Focardi, it seems likely that at times he has seen excess heat, but it seems unlikely that any of his public demos and tests produced the COP claimed. Though there is a chance that someone who believes Rossi’s results (and thus speculates about what Rossi did to achieve them) might result in a real success, it may be more effective to look at other experiments where the data is honest.

    In the blogs, there seems to be a feeling that if people think LENR works then they’ll be accepting what Rossi says, and that sceptics only need to point at Rossi’s results in order to show that LENR doesn’t work for real. This hard split seems to ignore the subtleties of the situation, where some parts of what Rossi says may be true but a lot isn’t. Other experimenters may also have errors in their results, but it’s less likely to be deliberate. Still, getting to a replicable and repeatable success, even at a low (but undeniable) level of excess heat will be a big help to the theorists in working out why and how it happens. If we can get to a recipe that always works, then maybe the theory will help in explaining and improving it.

      Regardless of what happened in Doral, Florida, the evidence is overwhelming that the Rossi Effect can produce extremely high levels of excess heat. For example, consider the 18 hour long test conducted in Bologna by Dr. Levi in which the reactor self sustained with virtually no input (a short period of about a thousand watts or so for a few minutes for a heat up and then only about 100 watts to provide power to the control system). The output at one point surged to 130kW, and Andrea Rossi instructed him to vent some hydrogen to reduce the reaction rate. Other tests conducted by Rossi point towards massive power output.

      The whole situation in regards to Doral is a distraction. I don’t know the truth about what transpired there, and I refuse to speculate until both sides put their cards on the table. But I’m convinced the Rossi Effect is absolutely and without a doubt real.

      • Simon Derricutt

        Hank – the melt-down of F+P’s 1cm cube of Palladium and the resultant 6-inch hole in the concrete floor should be a sufficient proof that LENR can produce a massive amount of energy, and by extension it’s not unreasonable that Ni/H may produce similar levels. For most Pd/D experiments the heat output has been low and has needed sensitive calorimeters, and for most Ni/H experiments (apart from Rossi’s claims) the output has been similarly low.

        The big problem is to get something that works every time you start it. Whereas I can accept that Rossi may have sometimes had a real success, this is not evident in the public demonstrations and I don’t have confidence that Rossi measured the heat output reliably. It appears to me that Rossi’s measurements were deliberately wrong, in fact.

        I thus prefer not to use the term “Rossi effect” but instead to use the more-generic term “LENR” since I’m not trusting what Rossi says. The Doral test in particular has too many discrepancies between what we should have seen and what was actually seen. Before the Doral test, I thought there was a chance that Rossi would succeed (and as you say there have been some experiments that seem to have succeeded) but the lack of preparation to deal with 1MW at Doral indicates to me that Rossi knew it wouldn’t work when he set it up.

        Despite all that I agree with you that LENR is real. I just don’t think Rossi has tamed it so that he can produce kW or MW at will. Because of that, I think that following what Rossi says to design an experiment is probably a waste of time – it’s better to look at what other people have done and to try to improve on that. Still, there’s Parkhomov who tried to work out what Rossi did and may have succeeded where Rossi didn’t, since he used a different process on his fuel mix. It’s possible that Rossi himself is now trying to replicate Parkhomov….

        In science we are used to the scientist not lying, though people often get things wrong or assign a wrong explanation of things at the start. There’s often a big dose of confirmation bias to deal with, too, but after a while things tend to settle down and we end up with reasonable explanations of why things happen the way they do. My suggestion here is that since it’s obvious that Rossi has told quite a few lies (and I’m not detailing them here) then trying to replicate what he says he’s done is not the best use of your time and money.

        I’m suggesting that we don’t let our wishes get in the way of a sober analysis of what data we can trust and what data we can’t trust. There’s also the need to be able to discard theories (that have been well-tested) in the face of experimental evidence that they are wrong – but we do need that experimental evidence to be reliable. As I see it, evidence from Rossi is not reliable.

    With respect to removing Nickel oxide layer, I would also refer to a patent application of Francesco Celani, which cites a Dutch patent application NL1001123C2. This patent application discusses various methods of reducing NiO, including the use of Hexaan. But more relevant it also describes that if NiO and CuO are present while reducing oxides using Hydrogen at a few hundreds degrees C, in essence the oxide of the more nobel metal (NiO) gets reduced first, showing that CuO acts a a kind of catalyst to remove NiO.
