The Energy Catalyzer (also called E-Cat) is a purported cold fusion or Low-Energy Nuclear Reaction (LENR) heat source[1][2] built by inventor Andrea Rossi[3][4] with support from physicist Sergio Focardi.[5][6] An Italian patent, which received a formal but not a technical examination, describes the apparatus as a "process and equipment to obtain exothermal reactions, in particular from nickel and hydrogen".[7][8] Rossi and Focardi say the device works by infusing heated hydrogen into nickel, transmuting it into copper and producing heat.[9][10] An international patent application[1] has received an unfavorable international preliminary report on patentability because it seemed to "offend against the generally accepted laws of physics and established theories" and to overcome this problem the application should have contained either experimental evidence or a firm theoretical basis in current scientific theories.[11]

The device has been demonstrated to invited audiences several times, and commented on by various academics and others, but has not independently tested. Professor Ugo Bardi of the University of Florence, noting contradictory claims made by Rossi regarding the emission or non-emission of gamma radiation, the location of a supposed factory – in Florida, or not in the United States at all – and the fact that some of his supporters are apparently deserting him, said "...the E-Cat has reached the end of the line. It still maintains some faithful supporters, but, most likely, it will soon fade away in the darkness of pathological science, where it belongs".[12] In reply to a non-peer-reviewed paper submitted to the arxiv digital archive in May 2013, he added that "...the story of the E-Cat keeps repeating itself. This is the n-th claim of success of a long series that has led to nothing verifiable and that has become rather boring. What's not boring in the story is the question of why these claims find so much resonance with people everywhere."[13]

Reactions to the claims

Because of his research into cold fusion for over 15 years, Sergio Focardi was contacted by Andrea Rossi in 2007 in order to validate the apparatus at its early stage of development.[14][15] After four years of work and measurements together with Rossi, Focardi concluded that nuclear fusion reactions happen inside the Energy Catalyzer. Focardi states that the nuclear process is facilitated by a secret additive, known only by Rossi and not by him. According to Focardi, the process would be much less intense without this additive.[16] Rossi and Focardi are then reported to have been unable to find a peer-reviewed scientific journal that would publish their paper describing how they claim the Energy Catalyzer operates.[17] Their paper appears only in Rossi's self-published blog,[18] Journal of Nuclear Physics.[19]

University of Bologna researchers have attended some E-Cat experiments, but only as observers. On 5 November 2011, the University of Bologna clarified that its researchers had not been involved in the demonstrations and that none of the experiments took place at the university. Rossi had signed a contract with the university, but no research had been done because Rossi hadn't made the first payment.[20][21][22][23] The contract was terminated by the university in January 2012 because Rossi hadn't fulfilled his contractual obligations.[24][25]

Peter Ekström, lecturer at the Department of Nuclear Physics at Lund University in Sweden, concluded in May 2011, "I am convinced that the whole story is one big scam, and that it will be revealed in less than one year."[26] He cites the unlikelihood of a chemical reaction being strong enough to overcome the Coulomb barrier, the lack of gamma rays, the lack of explanation for the origin of the extra energy, the lack of the expected radioactivity after fusing a proton with 58Ni, the unexplained occurrence of 11% iron in the spent fuel, the 10% copper in the spent fuel strangely having the same isotopic ratios as natural copper, and the lack of any unstable copper isotope in the spent fuel as if the reactor only produced stable isotopes.[26] Kjell Aleklett, physics professor at Uppsala University, said the percentage of copper was too high for any known reaction of nickel, and the copper had the same isotopic ratio as natural copper. He also stated, "Known chemical reactions cannot explain the amount of energy measured. A nuclear reaction can explain the amount of energy, but the knowledge we have today says that this reaction cannot take place."[27]

Other reactions to the device have been mixed. Dennis M. Bushnell, Chief Scientist at NASA Langley Research Center, described LENR as a "promising" technology and praised the work of Rossi and Focardi.[28] Roland Pettersson, retired Associate Professor from Uppsala University, Sweden, who witnessed the 6 October demonstration said "I'm convinced that this works, but there is still room for more measurements".[29] Skeptic James Randi, discussing the E-Cat in the context of previous cold fusion claims, predicts that it will eventually be revealed to not function as advertised.[30]

Theoretical astrophysicist Ethan Siegel and nuclear physicist Peter Thieberger argue that the claims for the E-Cat are incompatible with the fundamentals of nuclear physics.[31][32] In particular, the Coulomb barrier for the claimed fusion reaction is so high that it is unsurpassable anywhere in the known universe, including the interior of stars. The reaction also would create gamma radiation that would penetrate the few inches of shielding apparently provided by the E-Cat, leading to acute radiation syndrome in persons involved in the demonstrations.[31] Given numerous other scientific inconsistencies – such as the ratio of isotopes in the supposed copper "fusion product" being identical to that in natural copper[33] – the authors argue that it is now time "for the e-Cat's proponents to provide the provable, testable, reproducible science that can answer these straightforward physics objections."[31]

Swedish physicists, Hanno Essén and Sven Kullander stated that if the claims that they had read about the e-cat were true, then it must operate through some kind of a nuclear reaction. However, they had no access to privileged information about the catalysts in Rossi's device. According to Kullander it is "important "to consider the experimental facts and not indulge too much in speculation about what could happen in theory". Kullander also emphasized that measurements of excess heat must be made accurately and independently: "You have to rely on Rossi that he is true to what he conveys and through discussions with him we may try to conclude how reliable the measurements are."[34] [35]

Theoretical nuclear physicist Yeong E. Kim of Purdue University has proposed a potential theoretical explanation of the reported results of the device,[36] but has stated that, for confirmation of this theory, "it is very important to carry out Rossi-type experiments independently."[37] Kim had previously put forward this theory to explain the results of the discredited Fleischman and Pons cold fusion experiment in 1989.[38]

In October 2011 Mark Gibbs of Forbes observed: "until a verifiably objective analysis is conducted by an independent third party that confirms the results match the claims there's no real news".[39] In May 2013 he responded to a paper by scientists from Italian and Swedish Universities: "But much to my ... surprise, a report by credible, independent third parties is exactly what we got."[40][41]

Patents

An application in 2008 to patent the device internationally had received an unfavorable preliminary report on patentability at the World Intellectual Property Organization[42] from the European Patent Office, noting that the description of the device was based on "general statements and speculations" and citing "numerous deficiencies in both the description and in the evidence provided to support its feasibility" as well as incompatibilities with "generally accepted laws of physics and established theories."[43] The patent application was published on 15 October 2009.[1]

On 6 April 2011 an application was approved by the Italian Patent and Trademark Office, which issued a patent for the invention, valid only in Italy. Under then-current Italian law, the examination of the application was more formal and less technical than for the corresponding PCT application.[44][1][7][45] International, European, and U.S. patent applications are still pending.[46][1][7]

Demonstrations

Typically during demonstrations the device was covered up.[47] The device was not independently verified. Invited guests attended several demonstrations in Bologna in 2011.[16][48][49] Of a January demonstration, Discovery Channel analyst Benjamin Radford wrote that "If this all sounds fishy to you, it should," and that "In many ways cold fusion is similar to perpetual motion machines. The principles defy the laws of physics, but that doesn't stop people from periodically claiming to have invented or discovered one."[50] According to PhysOrg (11 August 2011), the demonstrations held from January to April 2011 had several flaws that compromised their credibility and Rossi had refused to perform tests that could verify his claims.[2]

The six published demonstrations from December 2010 to July 2011 might contain a crucial flaw, according to Australian researcher and skeptic Ian Bryce, who was investigating for entrepreneur Dick Smith. He believes that the E-cat is misconnected, and that the power attributed to fusion is supplied to the device through the earth wire. He noted that the misconnection could have been inadvertent.[51][52] Dick Smith offered Rossi one million dollars to demonstrate that the E-Cat system worked as claimed, while the power through the earth wire was also being measured, which Rossi refused.[53][54] Peter Thieberger, a senior physicist at Brookhaven National Laboratory, said it would be very difficult for this misconnection to happen by accident and that the issue could only be cleared with a fully independent test.[51]

Another demonstration on 6 October 2011 reportedly lasted for about eight hours.[55][56][57] Roland Pettersson, retired Associate Professor from the University of Uppsala, who witnessed it said "I'm convinced that this works, but there is still room for more measurements".[29]

On 28 October 2011 the unit was "customer tested" and was said to release 2,635 kWh during five and a half hours of self-sustained mode, an average power of 479 kilowatts – just under half the promised power of one megawatt. Independent observers were not allowed to watch the measurements or make their own, and the plant remained connected to a power supply during the test allegedly to supply power to the fans and the water pumps.[58][59][60][61]

Tests

In May 2013 a non-peer-reviewed paper describing "results obtained from evaluations of the operation of the E-Cat HT in two test runs" was submitted to the arxiv digital archive.[62] Although the authors of the paper wrote that they were not in control of all of the aspects of the process, they concluded that, even by the most conservative of measurements, the device produced excess heat with a resulting energy density that was at least one order of magnitude—and possibly several—higher than any other conventional energy source, including gasoline.[63][64][65]

Astrophysicist Ethan Siegel commented at scienceblogs saying Rossi did not allow the reactants or products to be measured on this occasion. despite that in the previous tests there was not enough Nickel-62 and Nickel-64 (the only two isotopes which can fuse with hydrogen), at 3.6% and 0.9% respectively, in the reactants to explain the 10% copper output and the 10% copper had the ratio found in nature, not after fusion. According to Siegel, Rossi also refused to unplug the machine while it was operating despite it being an easy way to surreptitiously power the device. He also added that the supposedly independent testers had to rely on data supplied by Rossi.[66]

Mark Gibbs commented on the credentials of the investigators, saying that "I find it hard to believe that Rossi could, somehow co-opt this diverse group into knowingly participating in a scam."[67]. David Hambling of Wired agrees that "it's no small matter to put your professional and academic reputation on the line like this, especially when there are so many accusations of fraud flying around.". He also notes that report was funded in part by ELFORSK AB, a Swedish energy industry research body, which released a formal statement that "The results are very remarkable. What lies behind the extraordinary heat production cannot be explained today."[68]

Commercial plans

Originally, a new Greek company, Defkalion, was to deliver a heating plant based on the Energy Catalyzer, but this deal was terminated.[69][70] Since then Defkalion have announced that they plan to make a similar device.[71][72] In 2012 an Italian company, Prometeon Srl,[73] became the official Italian licensee for the Energy Catalyzer.[74]

Ecat.com is a website for taking pre-orders for the device, run by four Swedish entrepreneurs, two of them particle physicists. One of the physicists, Magnus Holm, in response to suggestions that he was "contributing to fraud" replied "We are not engaged in any deception, and I do not think Rossi is engaged in any fraud either. If it would turn out that it does not work, in spite of everything, I would think it is about self-deception."[15] In September 2012 they pulled out from investing in a new version of the E-Cat, a prototype high temperature reactor, after a test by the SP Technical Research Institute of Sweden failed to demonstrate excess output energy because there was more input energy than measured by Rossi. Holm says that they are still interested in investing in the 1MW version, which they intend to validate separately.[75]
