Леонид Попов, 3 июня 2011
Произошёл новый поворот в спорном деле вокруг итальянского реактора холодного ядерного синтеза. Эксперт американского космического агентства выступил в поддержку установки. Однако механизм выработки энергии в ней якобы отличается от того, который выдвигают сами изобретатели.
Установка холодного ядерного синтеза (ХЯС http://ru.wikipedia.org/wiki/ ) Серджио Фокарди (Sergio Focardi) и Андреа Росси (Andrea A. Rossi) из университета Болоньи (Universit; di Bologna) была продемонстрирована в январе 2011 года. Об этом событии и о самом устройстве мы рассказывали детально http://www.membrana.ru/particle/15643 http://www.youtube.com/watch?v=7sZHOQ6P-Rw
http://www.youtube.com/watch?v=1UmoBoAcvxg&feature=related
.
В широких научных кругах известие вызвало здоровый скепсис. Все помнят, сколько в горячей теме холодного синтеза было фальстартов — преждевременных объявлений о победе и грядущем энергетическом счастье человечества.
А недавно ведущий учёный исследовательского центра Лэнгли (NASA Langley Research Center) Дэннис Бушнелл (Dennis Bushnell) выступил в пользу итальянцев. В интервью (MP3-файл) EV World он обратился к теме низкоэнергетических ядерных реакций (Low Energy Nuclear Reactions — LENR) как наиболее интересных и перспективных альтернативных технологий в стадии разработки, способных теоретически решить все наши энергетические и климатические проблемы.
Среди прочего Дэннис говорил о никель-водородном реакторе Росси. Однако Бушнелл категорически отказался считать выявленный процесс холодным ядерным синтезом, как и другие сходные с ним эксперименты в области LENR.
По информации PES Network, Бушнелл полагает, что вместо ХЯС в классическом понимании тут имеет место бета-распад, идущий в соответствии с теорией Видома-Ларсена (Widom Larsen theory).
По ней экзотические электроны, называемые «тяжёлыми поверхностными плазмонными поляритонами», объединяются с протонами, образуя нейтроны с очень низким импульсом. Эти нейтроны могут проникнуть в ядра атомов никеля (или другого металла), чтобы произвести ядерное превращение с выделением энергии.
Сторонники этой теории утверждают, что описанная реакция – вовсе не ядерный синтез, а только лишь захват нейтронов, и она не нарушает законов физики.
Тут нужно заметить, что у разных учёных имеются разночтения в отношении терминологии. Некоторые, скажем, считают холодный ядерный синтез и LENR синонимами без оговорок, другие пытаются разграничить эти понятия.
Возможно, такое разграничение помогает работам по LENR избавиться от негативной коннотации, заработанной ранее опытами по ХЯС, то есть от предубеждения со стороны некоторых учёных, относящихся к подобным экспериментам как к лженауке.
Но суть в любом случае проста — некий механизм позволяет в конечном счёте протону «обойти» кулоновский барьер, чтобы проникнуть в ядро атома и создать другой химический элемент (у Росси со товарищи якобы из никеля получалась медь). А вот как именно это происходит и происходит ли — так и неясно окончательно.
Сам Росси полагает, что теория Видома-Ларсена не объясняет работу его установки. Он заявил, будто теперь понимает, что именно происходит в реакторе. Тонкости, впрочем, опять не раскрывает.
Зато другие исследователи продолжают забрасывать посвящённое машине Росси и Фокарди частное издание Journal of Nuclear Physics новыми версиями работы реактора. Последняя появилась 25 мая нынешнего года.
Росси также напоминает всем скептикам, что внутри его реактора зафиксировано гамма-излучение, что анализ «отработанного» порошка свидетельствуют о трансмутации, и так далее. В общем, итальянец стоит на своём — это ХЯС! И, как и раньше, главным критерием истины Андреа считает… рынок.
С точки зрения официальной науки это несколько еретическая позиция. Но Росси и его соратники полагают, что пока физика во всём разберётся досконально, уйдёт время, которое можно потратить с пользой. Например, продавать чудо-реакторы синтеза клиентам.
Первый завод по выпуску своих установок Росси и компания намерены в ближайшем будущем открыть в Ксанти (Греция), а второй чуть позже в США. И главное — в октябре 2011 года итальянцы намерены явить миру мегаваттную установку холодного ядерного синтеза. Что-то нам подсказывает, даже она не снимет все вопросы и не прекратит споры.

Overview
Compiled by Sterling D. Allan, with Hank Mills
Pure Energy Systems News
Commenced January 17, 2011
Eng. Andrea A. Rossi and Professor Sergio Focardi of the University of Bologna (one of the oldest universities in the world [1]), have announced to the world that they have a cold fusion device capable of producing more than 10 kilowatts of heat power, while only consuming a fraction of that. On January 14, 2011, they gave the Worlds' first public demonstration of a nickel-hydrogen fusion reactor capable of producing a few kilowatts of thermal energy. At its peak, it is capable of generating 15,000 watts with just 400 watts input required. In a following test the same output was achieved but with only 80 watts of continual input.
They don't always use the term "cold fusion" do describe the process, but often refer to it as an amplifier or catalyzer process.
Focardi states:
"Experimentally, we obtained copper; and we believe that its appearance is due to the fusion of atomic nuclei of nickel and hydrogen, the ingredients that feed our reactor. Since hydrogen and nickel 'weigh' with less, copper must have released a lot of energy, since 'nothing is created or destroyed.' Indeed, the 'Missing Mass' has been transformed into energy, which we have measured: it is in the order of a few kilowatts, two hundred times the energy that was the beginning of the reaction." [2]
They also claim to be going into production, with the first units expected to ship by the second half of October of this year, with mass production commencing by the end of 2011. The first units will be used to build a one megawatt plant in Greece. This one megawatt plant will power a factory that will produce 300,000 ten-kilowatt units a year.
This would become the world's first commercially-ready "cold fusion" device. Licensees are mentioned, with contracts in the USA and in Europe. Mass production should escalate in 2-3 years. Presently, Rossi says they are manufacturing a 1 megawatt plant composed of 125 modules. These modules should begin shipping by the end of October. On January 31st, 2011, Rossi wrote: "The cost to produce the catalyzer is 1 cent per MWh generated; the life expectancy is 20 years; the cost impact is between 1 and 1.5 cents per MWh." [3]
In describing the operation of the device, he said: "To start up the reactor you have just to turn on a switch. The reactor works with enormous margins of safety, so there is no need of a particular skill. Just follow the instructions. The refueling is every 6 months and will be made by our dealers."
According to Rossi, the demonstrated device shown on January 14, 2011 is their industrial product that is claimed to be reliable and safe. In normal operation it would produce 8 units of output for every unit of input. Higher levels of output are possible, but can be dangerous. They will soon start serial production of their modules. Combining the modules in series and parallel arrays it is possible to reach every limit of power. The modules are designed to be connected in series and parallels.
Rossi also says that they have had one reactor that has run continually for two years, providing heat for a factory. It reduced the electric bill by 90%. Also, the reactors can self sustain by turning off the input, but they prefer to have an input. The device will be scheduled for maintenance every six months. You control it "just as you turn on and off your television set."
More than two thousand prototypes were built and destroyed in refining the design and learning how to control and scale up the reaction. [4]
Convinced they have already adequately proven this to the necessary parties, they are not in a hurry to give demonstrations to curious scientists. On January 21, 2011, Rossi wrote: "Yes there will be a Scientist talking about us, no demo anyway: no more demos before the start up of the 1 MW plant."
Patent granted for the energy catalyzer - The Italian energy catalyzer that seems to be based on an unknown nuclear reaction is now patented in Italy.
The examination continues regarding protection in the rest of the world. The Italian Patent Office granted a patent for the energy catalyzer on April 6, 2011, valid until April 9, 2028. (Ny Teknik; May 9, 2011)

Quoting from Ny Teknik
The Italian Patent Office, Ufficio Italiano Brevetti e Marchi, granted a patent for the energy catalyzer on April 6, 2011, valid until April 9, 2028.
The inventor is Andrea Rossi, while his wife Maddalena Pascucci is the patent owner.
The final content of the patent is public but not directly available online (details on how to order the content can be found here).
According to Rossi ten of the original 15 claims remain.
The patent office in Italy confirmed that the patent is a normal one which was granted after technical examination of the filed application.
According to other sources the examination of Italian patents, however, is more formal and less technical compared with the international patent review under the PCT procedure.
Starting on 1 July 2008 and onwards (filing date), Italian patent applications are subject to an investigation of patentability (see decree here). The patent application for the energy catalyzer was filed in April 2008.

METHOD AND APPARATUS FOR CARRYING OUT NICKEL AND HYDROGEN EXOTHERMAL REACTIONS; pub. Date: 15.10.2009
Abstract
A method and apparatus for carrying out highly efficient exothermal reaction between nickel and hydrogen atoms in a tube, preferably, though not necessary, a metal tube filled by a nickel powder and heated to a high temperature, preferably, though not necessary, from 150 to 5000C are herein disclosed. In the inventive apparatus, hydrogen is injected into the metal tube containing a highly pressurized nickel powder having a pressure, preferably though not necessarily, from 2 to 20 bars.
In October 2010, the international patent application under PCT received a negative initial assessment in a so-called International Search Report made by the International Searching Authority, and a negative International Preliminary Report on Patentability. The criticisms include the problem that the patent application lacks detail in describing the technology. The examination of the international patent application is now continuing in a regional and national phase, including assesment by the European Patent Office. [5]

Cold fusion
From Wikipedia, the free encyclopedia
Jump to: navigation, search
It has been suggested that this article be split into multiple articles. (Discuss) Proposed since April 2012.
This article is about the Fleischmann–Pons claims of nuclear fusion at room temperature. For the original use of the term 'cold fusion', see Muon-catalyzed fusion. For all other definitions, see Cold fusion (disambiguation).

Cold fusion is a proposed[1] type of nuclear reaction that would occur at relatively low temperatures compared with hot fusion. As a new type of nuclear reaction, it was proposed to explain reports by experimenters of anomalously high energy generation under certain specific laboratory conditions. It has been rejected by the mainstream scientific community because the original experimental results could not be replicated consistently and reliably, and because there is no generally accepted theoretical model of cold fusion.
Cold fusion gained attention after reports in 1989 by Stanley Pons and Martin Fleischmann (then one of the world's leading electrochemists)[2] that their apparatus had produced anomalous heat ("excess heat"), of a magnitude they asserted would defy explanation except in terms of nuclear processes. They further reported measuring small amounts of nuclear reaction byproducts, including neutrons and tritium.[1] The small tabletop experiment involved electrolysis of heavy water on the surface of a palladium (Pd) electrode.[3]
The reported results received wide media attention,[3] and raised hopes of a cheap and abundant source of energy.[4] Many scientists tried to replicate the experiment with the few details available. Hopes fell with the large number of negative replications, the withdrawal of many positive replications, the discovery of flaws and sources of experimental error in the original experiment, and finally the discovery that Fleischmann and Pons had not actually detected nuclear reaction byproducts.[5]
By late 1989, most scientists considered cold fusion claims dead,[6][7] and cold fusion subsequently gained a reputation as pathological science.[8][9] In 1989, a review panel organized by the US Department of Energy (DOE) found that the evidence for the discovery of a new nuclear process was not persuasive enough to start a special program, but was "sympathetic toward modest support" for experiments "within the present funding system." A second DOE review, convened in 2004 to look at new research, reached conclusions similar to the first.[10]
A small community[quantify] of researchers continues to investigate cold fusion,[6][11] now often preferring the designation low-energy nuclear reactions (LENR).[12][13] They have reported that, "under certain extreme conditions", they observe excess heat effects by interaction of hydrogen or deuterium with palladium, nickel or platinum. However, they cannot explain these observations and have not demonstrated reliable replication of the effects.[14] Since cold fusion articles are rarely published in refereed scientific journals, the results do not receive as much scrutiny as more mainstream topics,[15] and many scientists are not even aware that there is ongoing research.[16]

History
Nuclear fusion occurs at temperatures in the tens of millions of degrees. Speculations that nuclear fusion might happen at temperatures much lower than that seen in normal "hot" fusion nuclear reactions in the context of electrochemical loading of hydrogen in palladium and other similar metals have been suggested from time to time for nearly 100 years. In 1989, a claim by Stanley Pons and Martin Fleischmann (then one of the world's leading electrochemists) that such cold fusion had been observed caused a brief media sensation before other scientists began heavily criticizing their claim as being incorrect after many failed to replicate the excess heat. Since the initial announcement, cold fusion research has continued by a small community of committed researchers convinced that such reactions do happen and hoping to gain wider recognition for their experimental evidence. Claims to have produced marketable devices based on cold fusion have occurred since the 1990s.[citation needed]
Before the Fleischmann–Pons experiment
The ability of palladium to absorb hydrogen was recognized as early as the nineteenth century by Thomas Graham.[17] In the late 1920s, two Austrian born scientists, Friedrich Paneth and Kurt Peters, originally reported the transformation of hydrogen into helium by spontaneous nuclear catalysis when hydrogen was absorbed by finely divided palladium at room temperature. However, the authors later retracted that report, acknowledging that the helium they measured was due to background from the air.[17][18]
In 1927, Swedish scientist J. Tandberg stated that he had fused hydrogen into helium in an electrolytic cell with palladium electrodes.[17] On the basis of his work, he applied for a Swedish patent for "a method to produce helium and useful reaction energy". After deuterium was discovered in 1932, Tandberg continued his experiments with heavy water. Due to Paneth and Peters' retraction, Tandberg's patent application was eventually denied.[17] His application for a patent in 1927 was denied as he could not explain the physical process.[19]
The term "cold fusion" was used as early as 1956 in a New York Times article about Luis W. Alvarez's work on muon-catalyzed fusion.[20] E. Paul Palmer of Brigham Young University also used the term "cold fusion" in 1986 in an investigation of "geo-fusion", the possible existence of fusion in a planetary core.[21]
Fleischmann–Pons experiment
The most famous cold fusion claims were made by Stanley Pons and Martin Fleischmann in 1989. After a brief period of interest by the wider scientific community, their reports were called into question by nuclear physicists. Pons and Fleischmann never retracted their claims, but moved their research program to France after the controversy erupted.
Events preceding announcement
Electrolysis cell schematic
Martin Fleischmann of the University of Southampton and Stanley Pons of the University of Utah hypothesized that the high compression ratio and mobility of deuterium that could be achieved within palladium metal using electrolysis might result in nuclear fusion.[22] To investigate, they conducted electrolysis experiments using a palladium cathode and heavy water within a calorimeter, an insulated vessel designed to measure process heat. Current was applied continuously for many weeks, with the heavy water being renewed at intervals.[22] Some deuterium was thought to be accumulating within the cathode, but most was allowed to bubble out of the cell, joining oxygen produced at the anode.[23] For most of the time, the power input to the cell was equal to the calculated power leaving the cell within measurement accuracy, and the cell temperature was stable at around 30 °C. But then, at some point (in some of the experiments), the temperature rose suddenly to about 50 °C without changes in the input power. These high temperature phases would last for two days or more and would repeat several times in any given experiment once they had occurred. The calculated power leaving the cell was significantly higher than the input power during these high temperature phases. Eventually the high temperature phases would no longer occur within a particular cell.[23]
In 1988, Fleischmann and Pons applied to the United States Department of Energy for funding towards a larger series of experiments. Up to this point they had been funding their experiments using a small device built with $100,000 out-of-pocket.[24] The grant proposal was turned over for peer review, and one of the reviewers was Steven E. Jones of Brigham Young University.[24] Jones had worked for some time on muon-catalyzed fusion, a known method of inducing nuclear fusion without high temperatures, and had written an article on the topic entitled "Cold nuclear fusion" that had been published in Scientific American in July 1987. Fleischmann and Pons and co-workers met with Jones and co-workers on occasion in Utah to share research and techniques. During this time, Fleischmann and Pons described their experiments as generating considerable "excess energy", in the sense that it could not be explained by chemical reactions alone.[23] They felt that such a discovery could bear significant commercial value and would be entitled to patent protection. Jones, however, was measuring neutron flux, which was not of commercial interest.[24] To avoid future problems, the teams appeared to agree to simultaneously publish their results, though their accounts of their March 6 meeting differ.[25]
Announcement
In mid-March 1989, both research teams were ready to publish their findings, and Fleischmann and Jones had agreed to meet at an airport on March 24 to send their papers to Nature via FedEx.[25] Fleischmann and Pons, however, pressured by the University of Utah, which wanted to establish priority on the discovery,[26] broke their apparent agreement, submitting their paper to the Journal of Electroanalytical Chemistry on March 11, and disclosing their work via a press release [27] and press conference on March 23.[24] Jones, upset, faxed in his paper to Nature after the press conference.[25]
Fleischmann and Pons' announcement drew wide media attention.[28] Cold fusion was proposing the counterintuitive idea that a nuclear reaction could be caused to occur inside a chemically bound crystal structure.[29] But the 1986 discovery of high-temperature superconductivity had made the scientific community more open to revelations of unexpected scientific results that could have huge economic repercussions and that could be replicated reliably even if they had not been predicted by established conjecture.[30] And many scientists were also reminded of the M;ssbauer effect, a process involving nuclear transitions in a solid. Its discovery 30 years earlier had also been unexpected, though it was quickly replicated and explained within the existing physics framework.[29]
The announcement of a new clean source of energy came at a crucial time: adults still remembered the 1973 oil crisis and the problems caused by oil dependence, anthropogenic global warming was starting to become notorious, the anti-nuclear movement was labeling nuclear power plants as dangerous and getting them closed, people had in mind the consequences of strip mining, acid rain, the greenhouse effect, and the Exxon Valdez oil spill, which happened the day after the announcement.[31] In the press conference, Peterson, Fleischmann and Pons, backed by the solidity of their scientific credentials, repeatedly assured the journalists that cold fusion would solve all of these problems, and would provide a limitless inexhaustible source of clean energy, using only seawater as fuel.[32] They said the results had been confirmed dozens of times and they had no doubts about them.[33] In the accompanying press release Fleischmann was quoted saying: "What we have done is to open the door of a new research area, our indications are that the discovery will be relatively easy to make into a usable technology for generating heat and power, but continued work is needed, first, to further understand the science and secondly, to determine its value to energy economics." [27]
Response and fallout
Although the experimental protocol had not been published, physicists in several countries attempted, and failed, to replicate the excess heat phenomenon. The first paper submitted to Nature reproducing excess heat, although it passed peer-review, was rejected because most similar experiments were negative and there were no theories that could explain a positive result;[34] this paper was later accepted for publication by the journal Fusion Technology. Nathan Lewis, professor of Chemistry at the California Institute of Technology, led one of the most ambitious validation efforts, trying many variations on the experiment without success, while CERN physicist Douglas R. O. Morrison said that "essentially all" attempts in Western Europe had failed.[6] Even those reporting success had difficulty reproducing Fleischmann and Pons' results.[35] On April 10, 1989, a group at Texas A&M University published results of excess heat and later that day a group at the Georgia Institute of Technology announced neutron production—the strongest replication announced up to that point due to the detection of neutrons and the reputation of the lab.[36] In 12 April Pons was acclaimed at an ACS meeting.[36] But Georgia Tech retracted their announcement in 13 April, explaining that their neutron detectors gave false positives when exposed to heat.[37] Another attempt at independent replication, headed by Robert Huggins at Stanford University, which also reported early success with a light water control,[38] saved cold fusion almost single-handedly and became the only scientific support for cold fusion in the 26 April US Congress hearings.[39] But, when he finally presented his results, he reported an excess heat of only one celsius degree, a result that could be explained by chemical differences between heavy and light water in the presence of lithium,[notes 1] he had not tried to measure any radiation,[40] and his research was derided by scientists who saw it later.[41] For the next six weeks, competing claims, counterclaims, and suggested explanations kept what was referred to as "cold fusion" or "fusion confusion" in the news.[25][42]
In April 1989, Fleischmann and Pons published a "preliminary note" in the Journal of Electroanalytical Chemistry.[22] This paper notably showed a gamma peak without its corresponding Compton edge, which indicated they had made a mistake in claiming evidence of fusion byproducts.[43] Fleischmann and Pons replied to this critique,[44] but the only thing left clear was that no gamma ray had been registered and that Fleischmann refused to recognize any mistakes in the data.[45] A much longer paper published a year later went into details of calorimetry but did not include any nuclear measurements.[23]
Nevertheless, Fleischmann and Pons and a number of other researchers who found positive results remained convinced of their findings.[6] The University of Utah asked Congress to provide $25 million to pursue the research, and Pons was scheduled to meet with representatives of President Bush in early May.[6]
On April 30, 1989, cold fusion was declared dead by the New York Times. The Times called it a circus the same day, and the Boston Herald attacked cold fusion the following day.[46]
On May 1, 1989, the American Physical Society held a session on cold fusion in Baltimore, including many reports of experiments that failed to produce evidence of cold fusion. At the end of the session, eight of the nine leading speakers stated that they considered the initial Fleischmann and Pons claim dead with the ninth, Johann Rafelski, abstaining.[6] Steven E. Koonin of Caltech called the Utah report a result of "the incompetence and delusion of Pons and Fleischmann," which was met with a standing ovation.[47] Douglas R. O. Morrison, a physicist representing CERN, was the first to call the episode an example of pathological science.[6][48]
On May 4, due to all this new criticism, the meetings with various representatives from Washington were cancelled.[49]
From May 8 only the A&M tritium results kept cold fusion afloat.[50]
In July and November 1989, Nature published papers critical of cold fusion claims.[51][52] Negative results were also published in several other scientific journals including Science, Physical Review Letters, and Physical Review C (nuclear physics).[notes 2]
In August 1989, in spite of this trend, the state of Utah invested $4.5 million to create the National Cold Fusion Institute.[53]
The United States Department of Energy organized a special panel to review cold fusion theory and research.[54]:39 The panel issued its report in November 1989, concluding that results as of that date did not present convincing evidence that useful sources of energy would result from the phenomena attributed to cold fusion.[54]:36 The panel noted the large number of failures to replicate excess heat and the greater inconsistency of reports of nuclear reaction byproducts expected by established conjecture. Nuclear fusion of the type postulated would be inconsistent with current understanding and, if verified, would require established conjecture, perhaps even theory itself, to be extended in an unexpected way. The panel was against special funding for cold fusion research, but supported modest funding of "focused experiments within the general funding system."[54]:37 Cold fusion supporters continued to argue that the evidence for excess heat was strong, and in September 1990 the National Cold Fusion Institute listed 92 groups of researchers from 10 different countries that had reported corroborating evidence of excess heat. However, no further DOE nor NSF funding resulted from the panel's recommendation.[55] By this point, however, academic consensus had moved decidedly toward labeling cold fusion as a kind of "pathological science".[8][56]
In early May 1990 one of the two A&M researchers, Kevin Wolf, acknowledged the possibility of spiking, but said that the most likely explanation was tritium contamination in the palladium electrodes or simply contamination due to sloppy work.[57] In June 1990 an article in Science by science writer Gary Taubes destroyed the public credibility of the A&M tritium results when it accused its group leader John Bockris and one of his graduate students of spiking the cells with tritium.[58] In October 1990 Wolf finally said that the results were explained by tritium contamination in the rods.[59] An A&M cold fusion review panel found that the tritium evidence was not convincing and that, while they couldn't rule out spiking, contamination and measurements problems were more likely explanations,[60] and Bockris never got support from his faculty to resume his research.
In 30 June 1991 the National Cold Fusion Institute closed after it ran out of funds;[61] it found no excess heat, and its reports of tritium production were met with indifference.[62]
In 1 January 1991, Pons left his tenure, and both he and Fleischmann quietly left the United States.[62][63] In 1992 they resumed research with Toyota Motor Corporation's IMRA lab in France.[62] Fleischmann left for England in 1995, and the contract with Pons was not renewed in 1998 after spending $40 million with no tangible results.[64] The IMRA laboratory was closed in 1998 after spending ;12 million on cold fusion work.[65] Pons has made no public declarations since, and only Fleischmann continues giving talks and publishing papers.[64]
Mostly in the 1990s several books were published that were critical of cold fusion research methods and the conduct of cold fusion researchers.[66] Over the years several books have appeared that defended them.[67]
Subsequent research programs
After 1991, cold fusion research continued in relative obscurity, conducted by groups that had increasing difficulty securing public funding and keeping programs open. Research continues today in a few specific venues, but the wider scientific community has generally marginalized the research being done and researchers have had difficulty publishing in mainstream journals.[6][7][11][16]

Between 1992 and 1997, Japan's Ministry of International Trade and Industry sponsored a "New Hydrogen Energy (NHE)" program of US$20 million to research cold fusion.[68] Announcing the end of the program in 1997, the director and one-time proponent of cold fusion research Hideo Ikegami stated "We couldn't achieve what was first claimed in terms of cold fusion. (...) We can't find any reason to propose more money for the coming year or for the future."[68]
Also in the 1990s, India stopped its research in cold fusion at the Bhabha Atomic Research Centre because of the lack of consensus among mainstream scientists and the US denunciation of the research.[69] Yet, in 2008, the National Institute of Advanced Studies recommended the Indian government to revive this research. Projects were commenced at the Chennai's Indian Institute of Technology, the Bhabha Atomic Research Centre and the Indira Gandhi Centre for Atomic Research.[69] However, there is still skepticism among scientists and, for all practical purposes, research is still stopped.[70]
In 2006-2007 the Italian Ministry of Economic Development founded a research program, which claimed to have found excess power up to 500%.[71][72]
Ongoing

Small but committed groups of cold fusion researchers have continued to conduct experiments using Fleischmann and Pons electrolysis set-ups in spite of the rejection by the mainstream community.[11][73] Often they prefer to name their field Low Energy Nuclear Reactions (LENR) or Chemically Assisted Nuclear Reactions (CANR),[74] also Lattice Assisted Nuclear Reactions (LANR), Condensed Matter Nuclear Science (CMNS) and Lattice Enabled Nuclear Reactions; one of the reasons being to avoid the negative connotations associated with "cold fusion".[73][75] The new names avoid making bold implications, like implying that fusion is happening on them.[76] Proponents see them as a more accurate description of the theories they put forward.[77]
In 1999 the Japan C-F Research Society was established to promote the independent research into cold fusion that continued in Japan.[78] The society holds annual meetings, the 12th meeting took place on December 17–18, 2011 at Kobe University[79] In May 2008 Japanese researcher Yoshiaki Arata (Osaka University) demonstrated an experiment that produced heat when deuterium gas was introduced into a cell containing a mixture of palladium and zirconium oxide.[80] In an August 2009 peer reviewed paper Akira Kitamura (Kobe University) et al. reported about replication of this experiment.[81] Replication of earlier work by Arata had been claimed by McKubre at SRI.[82]
U.S. Navy researchers at the Space and Naval Warfare Systems Center (SPAWAR) in San Diego, have been studying cold fusion since 1989.[74][83] In 2002, they released a two-volume report, "Thermal and nuclear aspects of the Pd/D2O system," with a plea for funding.[84] This and other published papers prompted the 2004 DOE review.[74] In 2007, the Naval Research Laboratory published a literature review explaining why most researchers have usually been unable to replicate successful LENR experiments, saying that the loading ratio of gas to metal was the most crucial aspect, which can be affected by metal properties, cell configuration, and the experimental protocols.[85]
Darpa, the Pentagon's Defense Advanced Research Projects Agency, has been "quietly pursuing LENR for some years." and for 2012 plans to continue their collaboration with the Italian Department of Energy to "Establish scalability and scaling parameters in excess heat generation processes"[86][87]
The Italian National agency for new technologies, Energy and sustainable economic development (ENEA) continues basic research in ENEA departments, CNR Laboratories, INFN, Universities and Industrial laboratories in Italy, trying to achieve reliable reproducibility (i.e. getting the phenomena to happen in every cell, and inside a certain frame of time). In 2009 ENEA hosted the 15th cold fusion conference.[71][72]
A grant of $5.5 million given by Sidney Kimmel in February 2012 to the University of Missouri will be used to establish the Sidney Kimmel Institute for Nuclear Renaissance (SKINR). The grant is intended to support research into the interactions of hydrogen with palladium, nickel or platinum at extreme conditions.[14][88][89][90]
Claims of commercial devices
In January 2011 inventor Andrea Rossi together with researcher Sergio Focardi from the University of Bologna claimed to have successfully demonstrated commercially viable cold fusion in a device called an Energy Catalyzer. Other inventors have made similar claims in the past, however commercial devices are not available on the market.
Publications
The ISI identified cold fusion as the scientific topic with the largest number of published papers in 1989, of all scientific disciplines.[91] The number of papers sharply declined after 1990 because of two simultaneous phenomena:[91] scientists abandoning the field and journal editors declining to review new papers, and cold fusion fell off the ISI charts.[91][92] The publication in mainstream journals has continued to decline but has not entirely stopped; this has been interpreted variously as the work of aging proponents who refuse to abandon a dying field[who?], or as the normal publication rate in a small field that has found its natural niche.[92][notes 3] Researchers who got negative results abandoned the field, while others kept publishing.[93] A 1993 paper in Physics Letters A was the last paper published by Fleischmann, and "one of the last reports to be formally challenged on technical grounds by a cold fusion skeptic".[94]
The decline of publications in cold fusion has been described as a "failed information epidemics".[95] The sudden surge of supporters until roughly 50% of scientists support the theory, followed by a decline until there is only a very small number of supporters, has been described as a characteristic of pathological science.[96][notes 4] The lack of a shared set of unifying concepts and techniques has prevented the creation of a dense network of collaboration in the field; researchers perform efforts in their own and in disparate directions, making the transition to "normal" science more difficult.[97]
Cold fusion reports continued to be published in a small cluster of specialized journals like Journal of Electroanalytical Chemistry and Il Nuovo Cimento. Some papers also appeared in Journal of Physical Chemistry, Physics Letters A, International Journal of Hydrogen Energy, and a number of Japanese and Russian journals of physics, chemistry, and engineering.[92] Since 2005, Naturwissenschaften has published cold fusion papers; in 2009, the journal named a cold fusion researcher to its editorial board.
The Nobel Laureate Julian Schwinger declared himself a supporter of cold fusion in the fall of 1989, after much of the response to the initial reports had turned negative. He tried to publish his theoretical paper "Cold Fusion: A Hypothesis" in Physical Review Letters, but the peer reviewers rejected it so harshly that he felt deeply insulted, and he resigned from the American Physical Society (publisher of PRL) in protest.[98]
The Journal of Fusion Technology (FT) established a permanent feature in 1990 for cold fusion papers, publishing over a dozen papers per year and giving a mainstream outlet for cold fusion researchers. When editor-in-chief George H. Miley retired in 2001, the journal stopped accepting new cold fusion papers.[92] This has been cited as an example of the importance of sympathetic influential individuals to the publication of cold fusion papers in certain journals.[92]
In the 1990s, the groups that continued to research cold fusion and their supporters established periodicals such as Fusion Facts, Cold Fusion Magazine, Infinite Energy Magazine and New Energy Times to cover developments in cold fusion and other radical claims in energy production that were being ignored in other venues. In 2007 they established their own peer-reviewed journal, the Journal of Condensed Matter Nuclear Science.[99] The internet has also become a major means of communication and self-publication for CF researchers, allowing for revival of the research.[100]
Conferences
Cold fusion researchers were for many years unable to get papers accepted at scientific meetings, prompting the creation of their own conferences. The first International Conference on Cold Fusion (ICCF) was held in 1990, and has met every 12 to 18 months since. Attendees offered no criticism to papers and presentations for fear of giving ammunition to external critics;[101] thus allowing the proliferation of crackpots and hampering the conduct of serious science.[102] Critics and skeptics stopped attending these conferences, with the notable exception of Douglas Morrison,[103] who died in 2001. With the founding[104] in 2004 of the International Society for Condensed Matter Nuclear Science (ISCMNS), the conference was renamed the International Conference on Condensed Matter Nuclear Science (the reasons are explained in the "ongoing" section).[73][75][105] Cold fusion research is often referenced by proponents as "low-energy nuclear reactions", or LENR,[106] but according to sociologist Bart Simon the "cold fusion" label continues to serve a social function in creating a collective identity for the field.[73]
Since 2006, the American Physical Society (APS) has included cold fusion sessions at their semiannual meetings, clarifying that this does not imply a softening of skepticism.[107][108] Since 2007, the American Chemical Society (ACS) meetings also include "invited symposium(s)" on cold fusion.[109] An ACS program chair said that without a proper forum the matter would never be discussed and, "with the world facing an energy crisis, it is worth exploring all possibilities."[108]
On 22–25 March 2009, the American Chemical Society meeting included a four-day symposium in conjunction with the 20th anniversary of the announcement of cold fusion. Researchers working at the U.S. Navy's Space and Naval Warfare Systems Center (SPAWAR) reported detection of energetic neutrons using a heavy water electrolysis set-up and a CR-39 detector,[12][110] a result previously published in Die Naturwissenschaften.[111] The authors claim that these neutrons are indicative of nuclear reactions;[112] without quantitative analysis of the number, energy, and timing of the neutrons and exclusion of other potential sources, this interpretation is unlikely to find acceptance by the wider scientific community.[111][113]
Further reviews and funding issues
Around 1998 the University of Utah had already dropped its research after spending over $1 million, and in the summer of 1997 Japan cut off research and closed its own lab after spending $20 million.[114]
Cold fusion researchers themselves acknowledge that the flaws in the original announcement still cause their field to be marginalized and to suffer a chronic lack of funding[106], and no possibility of getting published.[115] University researchers are unwilling to investigate cold fusion because they would be ridiculed by their colleagues and their professional careers would be at risk.[116]In 1994, David Goodstein, a professor of physics at Caltech, advocated for increased attention from mainstream researchers and described cold fusion as:
a pariah field, cast out by the scientific establishment. Between cold fusion and respectable science there is virtually no communication at all. Cold fusion papers are almost never published in refereed scientific journals, with the result that those works don't receive the normal critical scrutiny that science requires. On the other hand, because the Cold-Fusioners see themselves as a community under siege, there is little internal criticism. Experiments and theories tend to be accepted at face value, for fear of providing even more fuel for external critics, if anyone outside the group was bothering to listen. In these circumstances, crackpots flourish, making matters worse for those who believe that there is serious science going on here.[29]
In August 2003 the U.S. energy secretary Abraham ordered the DOE to organize a second review of the field.[117] This was thanks to an April 2003 letter sent by MIT's Peter L. Hagelstein,[118]:3 and the publication of many new papers, including the Italian ENEA and other researchers in the 2003 International Cold Fusion Conference,[72] and a two-volume book by U.S. SPAWAR in 2002.[74] Cold fusion researchers were asked to present a review document of all the evidence since the 1989 review. The report was released in 2004. The reviewers were "split approximately evenly" on whether the experiments had produced energy in the form of heat, but "most reviewers, even those who accepted the evidence for excess power production, 'stated that the effects are not repeatable, the magnitude of the effect has not increased in over a decade of work, and that many of the reported experiments were not well documented.'".[117][119] In summary, reviewers found that cold fusion evidence was still not convincing 15 years later, and they didn't recommend a federal research program.[117][119] They did recommend individual well-thought studies, and specific areas where research could resolve the controversies in the field.[117][119] They summarized its conclusions thus:
While significant progress has been made in the sophistication of calorimeters since the review of this subject in 1989, the conclusions reached by the reviewers today are similar to those found in the 1989 review.
The current reviewers identified a number of basic science research areas that could be helpful in resolving some of the controversies in the field, two of which were: 1) material science aspects of deuterated metals using modern characterization techniques, and 2) the study of particles reportedly emitted from deuterated foils using state-of-the-art apparatus and methods. The reviewers believed that this field would benefit from the peer-review processes associated with proposal submission to agencies and paper submission to archival journals.

Cold fusion researchers placed a "rosier spin"[119] on the report, noting that they were finally being treated like normal scientists, and that the report had increased interest in the field and caused "a huge upswing in interest in funding cold fusion research."[119]
In a 2009 BBC article on a American Chemical Society's meeting on cold fusion, particle physicist Frank Close was quoted stating that the problems that plagued the original cold fusion announcement are still happening (as of 2009): results from studies are still not being independently verified and inexplicable phenomena encountered are being labelled as "cold fusion" even if they are not, in order to attract the attention of journalists.[106]
A small number of old and new researchers have remained interested in investigating cold fusion.[11][73] In 2007, one such researcher, the nuclear physicist and engineering professor Jean-Paul Biberian, surveyed the previous 15 years of cold fusion research and concluded that: "nuclear reactions not predicted by current theories occur in solids, during electrolysis, gas loading and gas discharge [experiments]".[121]
Experiments and reported results
A cold fusion experiment usually includes:
• a metal, such as palladium or nickel, in bulk, thin films or powder;
• deuterium and/or hydrogen, in the form of water, gas or plasma; and
• an excitation in the form of electricity, magnetism, temperature, pressure, laser beam(s), or of acoustic waves.[122]
Electrolysis cells can be either open cell or closed cell. In open cell systems, the electrolysis products, which are gaseous, are allowed to leave the cell. In closed cell experiments, the products are captured, for example by catalytically recombining the products in a separate part of the experimental system. These experiments generally strive for a steady state condition, with the electrolyte being replaced periodically. There are also "heat after death" experiments, where the evolution of heat is monitored after the electric current is turned off.
The most basic setup of a cold fusion cell consists of two electrodes submerged in a solution containing palladium and heavy water. The electrodes are then connected to a power source to transmit electricity from one electrode to the other through the solution.[110] Even when anomalous heat is reported, it can take weeks for it to begin to appear - this is known as the "loading time," the time required to saturate the palladium electrode with hydrogen (see "Loading ratio" section).
The Fleischmann and Pons early findings regarding helium, neutron radiation and tritium were never replicated satisfactorily, and its levels were too low for the claimed heat production and inconsistent with each other.[123] Neutron radiation has been reported in cold fusion experiments at very low levels using different kinds of detectors, but levels were too low, close to background, and found too infrequently to provide useful information about possible nuclear processes.[124]
Excess heat and energy production
An excess heat observation is based on an energy balance. Various sources of energy input and output are continuously measured. Under normal conditions, the energy input can be matched to the energy output to within experimental error. In experiments such as those run by Fleischmann and Pons, a cell operating steadily at one temperature transitions to operating at a higher temperature with no increase in applied current.[23] If higher temperatures were real, and not experimental artifact, the energy balance would show an unaccounted term. In the Fleischmann and Pons experiments, the rate of inferred excess heat generation was in the range of 10-20% of total input, though this could not be reliably replicated by most researchers.[120]:3 Researcher Nathan Lewis discovered that the excess heat in Fleischmann and Pons's original paper was not measured, but estimated from measurements that didn't have any excess heat.[125]
Unable to produce excess heat or neutrons, and with positive experiments being plagued by errors and giving disparate results, most researchers declared that heat production was not a real effect and ceased working on the experiments.[126]
In 1993, after the initial discrediting, Fleischmann reported "heat-after-death" experiments: where excess heat was measured after the electric current supplied to the electrolytic cell was turned off.[127] This type of report also became part of subsequent cold fusion claims.[128]
Helium, heavy elements, and neutrons
"Triple tracks" in a CR-39 plastic radiation detector claimed as evidence for neutron emission from palladium deuteride.
Known instances of nuclear reactions, aside from producing energy, also produce nucleons and particles on readily observable ballistic trajectories. In support of their claim that nuclear reactions took place in their electrolytic cells, Fleischmann and Pons reported a neutron flux of 4,000 neutrons per second, as well as detections of tritium. The classical branching ratio for previously known fusion reactions that produce tritium would predict, with 1 watt of power, the production of 1012 neutrons per second, levels that would have been fatal to the researchers.[129] In 2009, Mosier-Boss et al. reported what they called the first scientific report of highly energetic neutrons, using CR-39 plastic radiation detectors,[83] but the claims cannot be validated without a quantitative analysis of neutrons.[111][113]
Several medium and heavy elements like calcium, titanium, chromium, manganese, iron, cobalt, copper and zinc have been reported as detected by several researchers, like Tadahiko Mizuno or George Miley. The report presented to the DOE in 2004 indicated that deuterium-loaded foils could be used to detect fusion reaction products and, although the reviewers found the evidence presented to them as inconclusive, they indicated that those experiments did not use state of the art techniques.[120]:3,4,5
In response to skepticism about the lack of nuclear products, cold fusion researchers have tried to capture and measure nuclear products correlated with excess heat.[77][130] Considerable attention has been given to measuring 4He production.[13] However, the reported levels are very near to background, so contamination by trace amounts of helium normally present in the air cannot be ruled out. In the report presented to the DOE in 2004, the reviewers' opinion was divided on the evidence for 4He; with the most negative reviews concluding that although the amounts detected were above background levels, they were very close to them and therefore could be caused by contamination from air.[120]:3,4
One of the main criticisms of cold fusion was that deuteron-deuteron fusion into helium was expected to result in the production of gamma rays—which were not observed and were not observed in subsequent cold fusion experiments.[35][131] Cold fusion researchers have since claimed to find X-rays, helium, neutrons[132] and even nuclear transmutations.[133] Some of them even claim to have found them using only light water and nickel cathodes.[132] The 2004 DOE panel expressed concerns about the poor quality of the theoretical framework cold fusion proponents presented to account for the lack of gamma rays.[120]:3,4
Issues
Incompatibilities with conventional fusion
There are many reasons conventional fusion is an unlikely explanation for the experimental results described above.[134]
Repulsion forces
Because nuclei are all positively charged, they strongly repel one another.[35] Normally, in the absence of a catalyst such as a muon, very high kinetic energies are required to overcome this repulsion.[135] Extrapolating from known fusion rates, the rate for uncatalyzed fusion at room-temperature energy would be 50 orders of magnitude lower than needed to account for the reported excess heat.[136]
In muon-catalyzed fusion there are more fusions because the presence of the muon causes deuterium nuclei to be 207 times closer than in ordinary deuterium gas.[137] But deuterium nuclei inside a palladium lattice are further apart than in deuterium gas, and there should be fewer fusion reactions, not more.[138]
Paneth and Peters in the 1920s already knew that palladium can absorb up to 900 times its own volume of hydrogen gas, storing it at several thousands of times the atmospheric pressure.[139] This led them to believe that they could increase the nuclear fusion rate by simply loading palladium rods with hydrogen gas.[139] Tandberg then tried the same experiment but used electrolysis to make palladium absorb more deuterium and force the deuterium further together inside the rods, thus anticipating the main elements of Fleischmann and Pons' experiment.[139] They all hoped that pairs of hydrogen nuclei would fuse together to form helium nuclei, which at the time were very needed in Germany to fill zeppelins, but no evidence of helium or of increased fusion rate was ever found.[139]
This was also the belief of geologist Palmer, who convinced Steve Jones that the helium-3 occurring naturally in Earth came from the fusion of deuterium inside catalysts like palladium.[140] This led Jones to independently make the same experimental setup as Fleischmann and Pons (a palladium cathode submerged in heavy water, absorbing deuterium via electrolysis).[141] Fleischmann and Pons had the same incorrect belief,[142] but they calculated the pressure to be of 1027 atmospheres, when CF experiments only achieve a ratio of one to one, which only has between 10,000 and 20,000 atmospheres.[143] Huizenga says they had misinterpreted the Nernst equation, leading them to believe that there was enough pressure to bring deuterons so close to each other that there would be spontaneous fusions.[144]
Lack of expected reaction products
Conventional deuteron fusion is a two-step process,[134] in which an unstable high energy intermediary is formed:
D + D ; 4He * + 24 MeV
Experiments have observed only three decay pathways for this excited-state nucleus, with the branching ratio showing the probability that any given intermediate follows a particular pathway.[134] The products formed via these decay pathways are:
4He* ; n + 3He + 3.3 MeV (ratio=50%)
4He* ; p + 3H + 4.0 MeV (ratio=50%)
4He* ; 4He + ; + 24 MeV (ratio=10;6)
Only about one in one million of the intermediaries decay along the third pathway, making its products comparatively rare when compared to the other paths.[35] This result is consistent with the predictions of the Bohr model.[145] If one watt ( 1 eV = 1.602 x 10;19 joule) of nuclear power were produced from deuteron fusion consistent with known branching ratios, the resulting neutron and tritium (3H) production would be easily measured.[35][146] Some researchers reported detecting 4He but without the expected neutron or tritium production; such a result would require branching ratios strongly favouring the third pathway, with the actual rates of the first two pathways lower by at least five orders of magnitude than observations from other experiments, directly contradicting both theoretically predicted and observed branching probabilities.[134] Those reports of 4He production did not include detection of gamma rays, which would require the third pathway to have been changed somehow so that gamma rays are no longer emitted.[134]
The known rate of the decay process together with the inter-atomic spacing in a metallic crystal makes heat transfer of the 24 MeV excess energy into the host metal lattice prior to the intermediary's decay inexplicable in terms of conventional understandings of momentum and energy transfer,[147] and even then we would see measurable levels of radiations.[148] Also, experiments indicate that the ratios of deuterium fusion remain constant at different energies.[149] In general, pressure and chemical environment only cause small changes to fusion ratios.[149] An early explanation invoked the Oppenheimer–Phillips process at low energies, but its magnitude was too small to explain the altered ratios.[150]
Theoretical proposals
The initial cold fusion explanation was motivated by the high excess heat reported and by the insistence of the initial reviewer, Stephen E. Jones, that nuclear fusion might rationalize the data.[citation needed]
Researchers started proposing alternative explanations for Fleischmann and Pons' results even before various other labs reported null results.[151] Many years after the 1989 experiment, cold fusion researchers still haven't agreed on a single theoretical explanation or on a single experimental method that can produce replicable results [152] and continue to offer new proposals, which also fail to convince mainstream scientists.[77]
Hydrogen and its isotopes can be absorbed in certain solids, including palladium hydride, at high densities. This creates a high partial pressure, reducing the average separation of hydrogen isotopes, but nowhere near enough to create the fusion rates claimed in the original experiment.[138] It was proposed that a higher density of hydrogen inside the palladium and a lower potential barrier[clarification needed] could raise the possibility of fusion at lower temperatures than expected from a simple application of Coulomb's law. Electron screening of the positive hydrogen nuclei by the negative electrons in the palladium lattice was suggested to the 2004 DOE commission,[153] but the panel found the theoretical explanations (Charge Element 2) to be the weakest part of cold fusion claims.[154]
Skeptics have called cold fusion explanations ad hoc and lacking rigor,[155] and state that they are used by proponents simply to disregard the negative experiments—a symptom of pathological science.[156]
In May 2006, Allan Widom and Lewis Larsen published a theory of a four-step process involving weak force beta decay, as a form of Low Energy Nuclear Reaction .[157] This has become known as Widom-Larsen theory.
Setup of experiments
Reproducibility
In 1989, after Fleischmann and Pons had made their claims, many research groups tried to reproduce the Fleischmann-Pons experiment, without success. A few other research groups however reported successful reproductions of cold fusion during this time. In July 1989 an Indian group of BARC (P. K. Iyengar and M. Srinivasan) and in October 1989 a team from USA (Bockris et al.) reported on creation of tritium. In December 1990 Professor Richard Oriani of Minnesota University reported excess heat.[158][notes 5]
Groups that did report successes found that some of their cells were producing the effect where other cells that were built exactly the same and used the same materials were not producing the effect.[159] Researchers that continued to work on the topic have claimed that over the years many successful replications have been made, but still have problems getting reliable replications.[160] Reproducibility is one of the main principles of the scientific method, and its lack led most physicists to believe that the few positive reports could be attributed to experimental error.[159][161] The DOE 2004 report said among its conclusions and recommendations:
"Ordinarily, new scientific discoveries are claimed to be consistent and reproducible; as a result, if the experiments are not complicated, the discovery can usually be confirmed or disproved in a few months. The claims of cold fusion, however, are unusual in that even the strongest proponents of cold fusion assert that the experiments, for unknown reasons, are not consistent and reproducible at the present time. (...) Internal inconsistencies and lack of predictability and reproducibility remain serious concerns. (...) The Panel recommends that the cold fusion research efforts in the area of heat production focus primarily on confirming or disproving reports of excess heat."[120]
As David Goodstein explains,[29] proponents say that the positive results with excess heat and neutron emission are enough to prove that the phenomenon was real, that negative results didn't count because they could be caused by flaws in the setup, and that you can't prove an idea false by simply having a negative replication. This is a reversal of Karl Popper's falsifiability, which says that you can't prove ideas true, never mind how many times your experiment is successful, and that a single negative experiment can prove your idea wrong.[29] Most scientists follow Popper's idea of falsifiability and discarded cold fusion as soon as they weren't able to replicate the effect in their own laboratory.[29]
Loading ratio
Michael McKubre working on deuterium gas-based cold fusion cell used by SRI International.
Cold fusion researchers (McKubre since 1994,[160] Graham K. Hubler from the Naval Research Laboratory in 2007,[85] or ENEA in 2011[72]) have posited that a cell that was loaded with a deuterium/palladium ratio lower than 100% (or 1:1) would never produce excess heat.[160] Storms added in 1996 that the load ratio has to be maintained during many hours of electrolysis before the effects appear.[160] Since most of the negative replications in 1989-1990 didn't report their ratios, this has been proposed as an explanation for failed replications.[160] This loading ratio is tricky to obtain, and some batches of palladium never reach it because the pressure causes cracks in the palladium, allowing the deuterium to escape.[160] Unfortunately, Fleischmann and Pons never disclosed the deuterium/palladium ratio achieved in their cells,[162] there are no longer any batches of the palladium used by Fleischmann and Pons (because the supplier uses now a different manufacturing process),[160] and researchers still have problems finding batches of palladium that achieve heat production reliably.[160]
Misinterpretation of data
Some research groups initially reported that they had replicated the Fleischmann and Pons results but later retracted their reports and offered an alternative explanation for their original positive results. A group at Georgia Tech found problems with their neutron detector, and Texas A&M discovered bad wiring in their thermometers.[163] These retractions, combined with negative results from some famous laboratories,[6] led most scientists to conclude, as early as 1989, that no positive result should be attributed to cold fusion.[163][164]
Calorimetry errors
The calculation of excess heat in electrochemical cells involves certain assumptions.[165] Errors in these assumptions have been offered as non-nuclear explanations for excess heat.
One assumption made by Fleischmann and Pons is that the efficiency of electrolysis is nearly 100%, meaning nearly all the electricity applied to the cell resulted in electrolysis of water, with negligible resistive heating and substantially all the electrolysis product leaving the cell unchanged.[23] This assumption gives the amount of energy expended converting liquid D2O into gaseous D2 and O2.[166] The efficiency of electrolysis is less than one if hydrogen and oxygen recombine to a significant extent within the calorimeter. Several researchers have described potential mechanisms by which this process could occur and thereby account for excess heat in electrolysis experiments.[167][168][169]
Another assumption is that heat loss from the calorimeter maintains the same relationship with measured temperature as found when calibrating the calorimeter.[23] This assumption ceases to be accurate if the temperature distribution within the cell becomes significantly altered from the condition under which calibration measurements were made.[170] This can happen, for example, if fluid circulation within the cell becomes significantly altered.[171][172] Recombination of hydrogen and oxygen within the calorimeter would also alter the heat distribution and invalidate the calibration.[169][173][174]
John R. Huizenga who co-chaired the DOE 1989 panel stated simply a priori: "Furthermore, if the claimed excess heat exceeds that possible by other conventional processes (chemical, mechanical, etc.), one must conclude that an error has been made in measuring the excess heat."[175]
Initial lack of control experiments
Control experiments are part of the scientific method to prove that the measured effects do not happen by chance, but are direct results of the experiment. One of the points of criticism of Fleischmann and Pons was the lack of control experiments.[29]
Patents
Although details have not surfaced, it appears that the University of Utah forced the 23 March 1989 Fleischmann and Pons announcement to establish priority over the discovery and its patents before the joint publication with Jones.[26] The Massachusetts Institute of Technology (MIT) announced on 12 April 1989 that it had applied for its own patents based on theoretical work of one of its researchers, Peter L. Hagelstein, who had been sending papers to journals from the 5th to the 12th of April.[176] On 2 December 1993 the University of Utah licensed all its cold fusion patents to ENECO, a new company created to profit from cold fusion discoveries,[177] and on March 1998 it said that it would no longer defend its patents.[114]
The U.S. Patent and Trademark Office (USPTO) now rejects patents claiming cold fusion.[118] Esther Kepplinger, the deputy commissioner of patents in 2004, said that this was done using the same argument as with perpetual motion machines: that they do not work.[118] Patent applications are required to show that the invention is "useful", and this utility is dependent on the invention's ability to function.[178] In general USPTO rejections on the sole grounds of the invention's being "inoperative" are rare, since such rejections need to demonstrate "proof of total incapacity",[178] and cases where those rejections are upheld in a Federal Court are even rarer: nevertheless, in 2000, a rejection of a cold fusion patent was appealed in a Federal Court and it was upheld, in part on the grounds that the inventor was unable to establish the utility of the invention.[178][notes 6]
A U.S. patent might still be granted when given a different name to disassociate it from cold fusion,[179] though this strategy has had little success in the US: the same claims that need to be patented can identify it with cold fusion, and most of these patents cannot avoid mentioning Fleischmann and Pons' research due to legal constraints, thus alerting the patent reviewer that it is a cold-fusion-related patent.[179] David Voss said in 1999 that some patents that closely resemble cold fusion processes, and that use materials used in cold fusion, have been granted by the USPTO.[180] The inventor of three such patents had his applications initially rejected when they were reviewed by experts in nuclear science; but then he rewrote the patents to focus more in the electrochemical parts so they would be reviewed instead by experts in electrochemistry, who approved them.[180][181] When asked about the resemblance to cold fusion, the patent holder said that it used nuclear processes involving "new nuclear physics" unrelated to cold fusion.[180] Melvin Miles was granted in 2004 a patent for a cold fusion device, and in 2007 he described his efforts to remove all instances of "cold fusion" from the patent description to avoid having it rejected outright.[182]
At least one patent related to cold fusion has been granted by the European Patent Office.[183]
A patent only legally prevents others from using or benefiting from one's invention. However, the general public perceives a patent as a stamp of approval, and a holder of three cold fusion patents said the patents were very valuable and had helped in getting investments.[180]
In popular culture
In 'Undead Science', Sociologist Bart Simon references the following examples of cold fusion found in popular culture: Some scientists use cold fusion as a synonym of outrageous claims made with no supporting proof,[184] and courses of ethics in science give it as an example of pathological science.[184] It has appeared as a joke in Murphy Brown and The Simpsons.[184] It was adopted as a product name by software Coldfusion and a brand of protein bars (Cold Fusion Foods).[184] It has also appeared in commercial advertising as a synonym for impossible science, for example a 1995 ad of Pepsi Max.[184] In the 1994 comedy I.Q., Albert Einstein makes up a "cold fusion" science to help his niece start a romantic relationship.
The plot of The Saint, a 1997 action-adventure film, parallels the story of Fleischmann and Pons, but has a very different ending. The science is rejected by scientific skepticism in the US, but USSR scientists manage to build a working generator and start an age of "infinite energy".[184] The film might have affected the public perception of cold fusion, pushing it further into the science fiction realm.[184]
The plot of Chain Reaction, a 1996 science-fiction film, depicts a scientist discovering a new energy source that burns hydrogen and leaves only water as residue. It is never left clear if it's cold fusion or some form of hot fusion

ECAT Comparison
http://ecat.com/ecat-technology/ecat-comparison
The Energy Density of the ECAT is enormous only comparable with nuclear reactors. By weight the Energy Density is 200 000 times higher than oil and by volume the ECAT has a factor 2 million in energy density. This means that 1 liter of ECAT fuel represents over 100 tank trucks of oil. 1 Barrel of ECAT fuel represents a filled supertanker with oil. The difference is so staggering that it is hard to comprehend. The impact on transport and geo-economics will be severe. Japan is harvesting Uranium from the ocean at concentrations as low as 5ppb due to the energy content in nuclear reactions. The ECAT offer energy densities at higher levels than those of uranium with abundant non-radiactive materials. The ECAT process is non-radioactive and leaves no residual radioactive materials.

Exothermic Chemical Reactions
http://ecat.com/ecat-technology/ecat-science
Heat is produced in the chemical reaction in which hydrogen and oxygen are combined into water; i.e. the combustion of hydrogen. Such chemical reactions in which heat is produced are called exothermic reactions. The chemical equation for this reaction for one mol of hydrogen is written,
H2+1/2 O2=H2O+286 kJ (1)
That means, when one mol of hydrogen burns in oxygen (or air), 286 kJ of heat is produced.
Another example is,
C+O2=CO2+394 kJ (2)
where one mol of carbon is combusted into carbon dioxide under the production of 394 kJ of heat.
The heat productions of the above chemical equations, (1) and (2), represents one mol of hydrogen and carbon, respectively. In order to compare these chemical reactions with nuclear reactions, it is convenient to recalculate the heat production for one molecule or one atom. For this, let us divide the heat production by the Avogadro constant
NA=6.02;1023mol-1
The results are
H2+1/2 O2=H2O+3.0 eV (3)
C+O2=CO2+4.1 eV (4)
Equation (3) means that the process in which one hydrogen molecule (two hydrogen atoms) and one half oxygen molecule combine into one water molecule generates 3.0 eV energy in the form of heat (i.e. 1.5 eV per hydrogen atom). And Eq. (4) says that, when a carbon atom combines with an oxygen molecule and become a carbon dioxiside molecule, 4.1 eV energy is released.
The use eV is because it is the most common unit of energy used in the atomic and nuclear world. It is the work done on an electron that is accelerated through a potential difference of one volt. Its value is
1 eV = 1.6 x 10-19 J
Moreover, the units of energy, keV and MeV, are often used in the nuclear world; the former is 1,000 times eV and the latter 1,000,000 times eV.
When it comes to arbitrary carbohydrate based fuels the energy production will be of the oreder of 4 eV x #(carbon atoms) +1.5eV x #(hydrogen atoms) per molecule combusted in oxygen.
Exothermic Nuclear Reactions
Nuclei show various types of reactions: For example, one nuclide splits into two or more fragments. This type of reaction is called nuclear fission. Contrarily, two nuclides sometimes combine with each other to form a new nuclide. This type of reaction is called nuclear fusion. There are many other types of reaction processes; they are generally simply called nuclear reactions and contain everything from gamma emission to alpha deacys.
Among these various types of nuclear reactions, there are some types of exothermic reactions which are sometimes called “exoergic” reactions in nuclear physics.
The nucleus of deuterium atom is called deuteron which consists of a proton and a neutron. It is represented by a symbol “d”. The nuclear reaction in which two deuterons bind with each other is an example of nuclear fusion. This exoergic reaction is written has 3 forms,
d+d->32He+n+3.27 MeV (5)
d+d->31T+p+4.03 MeV
d+d->42He+24 MeV
If a neutron is absorbed in the uranium-235 nucleus (23592U), it would split into two fragments of almost equal masses and produce some number of neutrons and energy Q. One of the equations for the processes is
23592U+n->13756Ba + 9736Kr + 2n + Q (6)
This is an example of nuclear fission.
The amount of energy released in this process is about 200 MeV which will be explained in more detail in next section.
The Origin of the Nuclear Energy
Let us take up the d-d fusion reaction shown by the above Eq. (5) as an example. Since the experimental value of the binding energy of deuteron is 2.2246 MeV, the sum of the binding energies of the two deuterons before the reaction (on the left-hand side of Eq.(5)) is 4.449 MeV. On the other hand, the experimental value of the binding energy of (32He) is 7.719 MeV. Therefore the total binding energy after the reaction (on the right-hand side of Eq. (5)) is 3.27 MeV (= 7.719 – 4.449) larger than the binding energy before the reaction (on the left-hand side of Eq. (5)). Thereby the total mass decreases after the reaction and the mass defect corresponding to the above increase of the binding energy occurs. This mass defect is released as heat (or energy) in this exothermic (or exoergic) process.
Looking at the fission of uranium-235 (23592U) shown by Eq. (6), the binding energy per nucleon in nuclei around A = 240 is about 7.5 MeV. On the other hand, that in nuclei around A = 120 is about 8.5 MeV. Accordingly, if a uranium nucleus splits into two fragments with almost equal masses, the binding energy per nucleon would increase by about 1 MeV and the total mass of the fission fragments would decrease by the corresponding amount. This loss of mass (or mass defect) is converted into the heat (or energy) product Q. Since an energy of about 1 MeV per nucleon is released, the total energy Q would be more than 200 MeV.
According to the above discussions, it becomes clear that the origin of nuclear energy is the change of nuclear masses, and it is based on the principle of Einstein’s Mass-Energy Equivalence.
If the total binding energy after the reaction is larger than before, the total sum of the masses of the reaction products becomes smaller than that before the reaction. This decrease in mass is converted into an energy, so that the process would be an exothermic (exoergic) reaction.
The Origin of the Heat in Exothermic Chemical Reaction, Law of Energy Conservation
If hydrogen and carbon burn in oxygen gas, heat or energy is produced but what is the origin of this heat or energy? The principle of the heat production in chemical reaction is just the same as that in the nuclear reaction.
The hydrogen molecule is a bound system of two hydrogen atoms. The mass of a hydrogen molecule is slightly smaller than the sum of the masses of two hydrogen atoms. Converting this difference (= mass defect) into an energy with Einstein’s Mass-Energy Equivalence, we have the binding energy of the hydrogen molecule.
In the process of combustion of hydrogen represented by Eq. (3), the total mass after the reaction is slightly smaller than before, and this decrease in mass is transformed into heat in the exothermic reaction.
Strictly speaking, conservation of mass does not hold in a chemical reaction, though, both in chemical and nuclear reactions, the energy of the total system with converting mass into energy is conserved before and after the reaction.
Huge Amount of Nuclear Energy
Comparing Eq. (3) with (5), and Eq. (4) with (6), we can easily understand that the nuclear reactions yield a huge amount of energy in comparison with ordinary combustion processes.
As explained above, the energy produced from an exothermic chemical reaction like combustion of hydrogen or carbon is about 3 or 4 eV per molecule and atom, respectively. In contrast, d-d fusion reaction shown by Eq. (5) releases at least 3.27 MeV of energy. It is about one million times as large as the ordinary combustion.
In the fission of uranium-235 shown by Eq. (6), more energy than 200 MeV is released. It is about 100 million times as large as an ordinary chemical reaction.
Thus, the nuclear energy released in nuclear fission and fusion is several millions times as large as an ordinary chemical reaction like a combustion process.
ECAT Reactions
The reactions in the ECAT is called Cold Fusion or Low Energy Nuclear Reactions (LENR). Cold Fusion has had some bitter taste to its name the recent decenia due to the lack of repeatability in the experiments and because of the pressure from the Hot Fusion establishment which have been receiving over 50 billion dollars of funds during the last 50 years without any major breakthroughs. Add to that the fact that the theorists have had a hard time explaning the reactions going on in the Cold Fusion processes. The biggest challenge they face is to explain the three miracles of Cold Fusion reactions, namely
1. The Penetration of the Coulomb Barrier
2. The lack of strong Neutron Emissions
3. The lack of strong Gamma Ray Emissions
One theory worth mentioning is the Widom-Larsen theory and the Widom-Larsen Theory of Transmutations. It explains the Cold Fusion process by the Standard Model using weak interactions, without the need of introducing any new physics. This is also the theory NASA recently started to put to the test. When it comes to Cold Fusion mainly two types of processes have been experimented with, namely Palladium-Deuterium (Pd-D) and Nickel-Hydrogen (Ni-H). In the Palladium Deuterium fusues to Helium4 and releases 24 MeV per reaction while in the Ni-H process Nickel transmutes into mainly copper. The ECAT is built around the Ni-H process where Andrea Rossi through an ingenious catalyst has reached reaction rates which corresponds to several kW/kg. One of these processes is,
Ni62+H->Cu63+6.12 MeV.
What is significant with all these proton capture processes is that most are exothermic releasing energy of just short of one unit of the normal nuclear binding energy (7.5-8.5 MeV). The extremely interesting part of the Ni-H process is the severe amount of different transmutations occuring.
More or less all sorts of elements are created in the process, all with different reaction rates where the most frequent reactions surpasses the least frequent ones with a factor million. This is one of the things the Widom-Larsen theory is able to explain.
The Widom-Larsen theory is just one of many theories trying to explain the physics that occur in Low Energy Nuclear Reactions. Before the theorists reach a consensus on how the reactions occur one can only speculate on which theory is true and which is not.
For the interested ECAT.com has calculated the energy release of all known isotopes for both proton capture and deutron capture (coming soon).
