reason also pertains to the products of the reaction. The problem with cold fusion is not that it is theoretically impossible, but that it has not been demonstrated consistently in experiments. If we refuse to acknowledge the possibility that existing scientific institutions are not working as well as they might, we do something to reinforce it. He had two pieces of news in mind. Less noted is research into so-called "cold other than typesetting and referencing guidelines. I don’t need to deny that your reaction is an appropriate one, by the standards of science as we currently practice it, or that those standards work pretty well in general. That makes no sense at all. Even proponents of cold fusion admit this is a difficult aspect to explain and resort to ref… Photo courtesy NASA, Physiognomies of Russian criminals from The Delinquent Woman (1893) by Cesare Lombroso. Recently an aircraft company, it was McDonnell Douglas, claimed that they’d be able to make cold fusion happen at room temperature. It was about science and “cold fusion,” which means, in this context, fusion at low energies. Some, including a team at one of Italy’s leading research centres, say that they have many replications of the Fleischmann and Pons results. Finally, very recently, there’s a paper by two senior Swedish physicists, Rickard Lundin and Hans Lidgren, proposing a mechanism for Rossi’s results, inspired in part by the second of two test reports mentioned above. the reasons why cold fusion is unlikely to be possible based on an Support our work to create a unique home for ideas beyond the news cycle. He is also academic director of the Centre for the Study of Existential Risk, and the Leverhulme Centre for the Future of Intelligence, The joys and heartbreaks of loving a creature who ages faster than you, Algorithms associating appearance and criminality have a dark past, Simple objects make for epic art installations of sound and movement, Gentle medicine could radically transform medical practice. Also, it should be done with fairly simple equipment, another thing that a particle accelerator isn't. We can fuse two particles together in particle accelerators, but that is hardly normal . difficult aspect to explain and resort to referring to unknown Without CF, people will keep burning carbon-base fuels and using uranium until either the byproducts destroy the environment or these energy sources become too expensive because of their increased rarity. But there’s more, much more. The nuclear physics and solid state physics, both based on quantum mechanics, are well-developed theories of physics. People outside the trap won’t go near it, for fear of falling in. is that a real result should be reproducible. The following facts play an important role in the evaluation of cold nuclear fusion. attribute their observed extra enthalpy to fusion of deuterium. It was Lockheed Martin. In that case, well-performed experiments claiming to overturn the failure to replicate would certainly be of great interest. This is not to deny that there is truth in the principle popularised by Carl Sagan, that extraordinary claims require extraordinary evidence. Of interesting note is Andrea Rossi and his cold fusion energy generator. energy released should be in the form of gamma rays rather Modern physics held forth the promise of cold fusion which could create energy just like the combustion of the stars and the sun. Today: fusion power. Physicist: In a nutshell, fusion is about fusing small atoms, specifically hydrogen, together to form larger atoms, specifically helium. Cold fusion is basically just nuclear reactions at reasonably normal temperatures and pressures. (So has every other physicist I’ve asked about it since.) I’m on my iPhone now, but you could google “Farnsworth fusor.” “Hydrogen bombs” use fusion for the extremely high energy release. I favoured Rossi, on grounds of the physics. Courtesy the Wellcome Collection, Hedonism at the court of kings. Palladium-Deuterium-Heavy Water System," J. Electroanal. Atomic nuclei are positively charged and therefore repel each other. In a case like this, there is very little cost to a false positive. permission to copy, distribute and display this work in unaltered form, So we agreed to bet a dinner on the issue. He thought it was the neutrinos, because the work had been done by respectable scientists rather than a lone engineer with a somewhat chequered past. This piece was made possible in part through the support of a grant on Managing Extreme Technological Risk, from the Templeton World Charity Foundation. something, it does not mean it is not real. to fuse, they must come within nuclear distances of each effects caused by the solid state host. Until quite recently, he says, he shared the conventional view that ‘the subject was dead’. But we could try to learn from our mistakes. It simply requires a But this would make a nonsense of the fuss over the failure to reproduce Fleischmann and Pons’ findings. Failure to replicate couldn’t possibly be more than provisional – empirical science is a fallible business, as any good scientist would acknowledge. Nuclear energy is \"hot\" fusion and an example is the power of the sun. None of us, not even philosophers, are mere spectators in this case. But this is compatible with the claim that they can be harmful in special cases (of which cold fusion might be one) – and that we could do better if we were better at identifying those cases in advance. miracle for the Coulomb barrier to breached at room 287, 293 (1990). reaction, neutrons should be produced in large numbers. Favorite Answer In order to trigger fusion the nuclei need to approach very close which means they need very high kinetic energy. The other concerned Andrea Rossi, an engineer from Bologna, who claimed to have a cold fusion reactor producing commercially useful amounts of heat. [2] Indeed, while the prospect of cold fusion is undoubtedly "Cold fusion has no merit," said Steven B. Krivit , publisher and senior editor, of the New Energy Times, who has covered LENR research for nearly a decade and authored books on the subject. Photo by Massimo Brega/SPL. His most recent book is Expressivism, Pragmatism and Representationalism (2013). attractive, based on all of what we know about nuclear physics, it is We know that there’s an abundant supply of clean, cheap water, trapped behind the dam. What we should have done instead is to have engineered the exact opposite of a reputation trap – perhaps an X Prize-like reward for the first reliable replication of the Fleischmann and Pons results, above some commercial bar. Cold fusion, means doing this in a controlled, consistent way on a small scale, like a power plant, as opposed to something like a bomb. And in any case, it is simply not true. That is why physicists were so surprised when two chemists, Fleischmann and Pons (F&P), announced the discovery of cold fusion, presumably similar to hot fusion but taking place at room temperature. Never a good idea. As several people have noticed, a new clean source of energy would be really, really useful right about now. But if the potential news is this big, why haven’t most of you heard about Rossi, or Godes, or any of the other people who have been working in the area (for many years, in some cases)? No doubt one could find some physicists who would claim it was impossible. Atomic nuclei are positively charged and therefore repel each other. Most recently, Lundin and Lidgren reported that they had submitted their paper to the journal Plasma Physics and Controlled Fusion, but that the editors declined to have it reviewed; and that even the non-reviewed preprint archive, arxiv.org, refused to accept it. of the order of 10 W per cubic centimeter of palladium, far exceeding Cold fusion is tainted, and the taint is contagious – anyone seen to take it seriously risks contamination.

Yet if that were the real reason, then the rejection would have to be provisional. The neutrinos challenged a fundamental principle of Albert Einstein’s theory of special relativity, which says that nothing can travel faster than light. We could take our seats on the sidelines and wait to see whether walls fall – whether distinguished skeptics end up with egg on their faces. It is possible, and high school kids make it happen in their garage. My friend would pay if Rossi turned out to have something genuine, and I would pay if the neutrinos came up trumps. We know that huge amounts of energy are locked up in metastable nuclear configurations, trapped like water behind a dam. Ever since 1989, in fact, the whole subject has been largely off-limits in mainstream scientific circles. If the field is indeed in the process of digging itself out of the reputation trap, then Darden deserves much of the credit. The opinions expressed here are my own and do not necessarily reflect the views of TWCF. The field never entirely went away, nor vanished from the laboratories of respected institutions. I … I suspect there are some in the area of emerging extreme risks, another field in which I have some interest. But he still put more weight on the sociological factors – reputation, as it were. After all, the standard line is that the rejection of cold fusion in 1989 turned on the failure to replicate the claims of Fleischmann and Pons. Cold fusion is dismissed as pseudoscience, the kind of thing that respectable scientists and science journalists simply don’t talk about (unless to remind us of its disgrace). Fifty years ago, Thomas Kuhn taught us that this is the usual way for science to deal with paradigm-threatening anomalies. We know that the energy is in there, after all. Once again, it was the reputation trap at work. understanding of nuclear physics. The only way to get past [2] M. Fleischmann et al., "Calorimetry of the There are big issues here. Rossi, however, has been going from strength to strength. schematic of the experimental setup is shown in Fig. nuclei, when enmeshed within a lattice, can somehow be induced to fuse. with attribution to the author, for noncommercial purposes only. "Why Don't We Have" is a PopMech series that seeks to quickly explain just why some of the technologies promised by science fiction have yet to become fact. Chem. (Rossi’s own background is not in these laboratories, but he acknowledges that his methods owe much to those who are, or were – especially to the late Sergio Focardi, one of the pioneers of the field.) Induced Nuclear Fusion of Deuterium," J. Electroanal. My friend agreed with me about the physics. Lundin and Lidgren say that the ‘experimental results by Rossi and co-workers and their E-Cat reactor provide the best experimental verification’ of the process they propose. What if the failure to replicate wasn’t crucial after all? We will use the email address you provide to send you daily and/or weekly emails (depending on your selection). But there may be a huge cost to a false negative. We have taken reasonable measures to protect information about you from loss, theft, misuse or unauthorised access, disclosure, alteration and destruction. In the processes a lot of energy is released. People inside the trap are already regarded as disreputable, an attitude that trumps any efforts that they might make to argue their way out, by reason and evidence. This Email Newsletter Privacy Statement may change from time to time and was last revised 18 May, 2020. But – so far as I knew – there was no ‘watertight’ argument that such methods were impossible. To anyone willing to listen, the community will say that they have amassed a great deal of evidence of excess heat, not explicable in chemical terms, and of various markers of nuclear processes. In a case like this, there is very little cost to a false positive – to investing some time and money in an avenue that in the end turns out to go nowhere. COLD FUSION: AN IMPOSSIBLE INVENTION? 1. Again, the explanation for ignoring these claims cannot be that other attempts failed 25 years ago. than as heat. There’s no known way to get useful access to it at low temperatures. Meanwhile cold fusion (or LENR, for ‘low-energy nuclear reaction’) is the controversial idea that nuclear reactions similar to those in the Sun could, under certain conditions, also occur close to room temperature. No physical or electronic security system is impenetrable however and you should take your own precautions to protect the security of any personally identifiable information you transmit. If LENR does develop in the direction I now think likely, we might be able to salvage something useful from mistakes in this case. The concept that cold fusion was impossible was always seriously defective. At last I can explain what I meant earlier, when I asked you to hold on to the thought that I must be a bit flaky myself, if that was your reaction to my willingness to take cold fusion seriously. Here are five reasons that cold fusion probably can't work, at least according to the laws of physics. In a more rational world, you wouldn’t think I’m flaky. 261, The results are ignored because they concern cold fusion, which we ‘know’ to be pseudoscience – we know it because attempts to replicate these experiments failed 25 years ago! This Email Newsletter Privacy Statement pertains to the personally identifying information you voluntarily submit in the form of your email address to receive our email newsletters. ‘We’ve had some success, and we’re expanding our work… and believe that we may be, at last, on the verge of a new paradigm shift.’ Finally, he expresses his appreciation to his audience, the LENR community themselves, and recalls another controversial piece of Italian science: It would be easy to overstate the analogy between mainstream institutions and the Inquisition, but it isn’t entirely empty. The email address/es you provide will be transferred to our external marketing automation service ‘MailChimp’ for processing in accordance with their. My task will be easier if you are still suffering from the symptoms.). There is also no evidence for gamma rays in _Currently_ there is no theory that explains how to do fusion without massive amounts of heat, ergo cold fusion IS (currently) theoretically impossible. alternative energy source is focused on hot fusion - the containment and All First the question is not if Cold Fusion (I assume F&P excess heat anomaly in transition metal hydrides, aka LENR) is possible but if it is observed. The borders of dominant paradigms are often protected by reputation traps, which deter all but the most reckless or brilliant critics. Chem. Otherwise there … As several people have noticed, a new clean source of energy would be really, really useful right about now. If the reputation trap makes it impossible to question the role of the reputation trap, then the Cardinals are winning. absorbing hydrogen within its lattice and the claim is that deuterium But several independent enquiries about LENR within a matter of weeks convinced him that there was something worth investigating: He reports that things have been going very well. other. More generally, when visiting the Aeon site you should refer to our site Privacy Policy here. But until that day comes, the default assumption is that anyone who’s claiming to have cold fusion is some combination of either unethical or incompetent. This alone would be enough to explain why I’ve been finding Rossi’s apparent progress so stimulating. Here, we outline three reasons for why reports of Outsiders might be surprised to learn how well-populated the trap actually is, in the case of cold fusion and LENR.

Superluminal neutrinos would overturn a fundamental tenet of relativity, but all Rossi needed was a previously unnoticed channel to a reservoir of energy whose existence is not in doubt. Sociology is one thing, but rational explanation another. So the subject is stuck in a place that is largely inaccessible to reason – a reputation trap, we might call it. Mainstream research into nuclear fusion as a If Rossi and Godes et al are actually on to something, then the field is going to be mainstream soon anyway. Another prominent example is Robert Godes, of the California-based Brillouin Energy. Why Cold Fusion should be impossible. what can be accounted for by chemical reactions, when electrolysis of The most obvious objection has to do with temperature. There might be other potential cases with a similar payoff structure (a high cost for false negatives, with a low cost for false positives). We are like a thirsty town, desperate for a new water supply. When you receive the information, if you think any of it is wrong or out of date, you can ask us to change or delete it for you. We’d split the bill if, as then seemed highly likely, both claims turned out to be false. Since then, there’s been a big reputation cost to any engineer who takes up the issue. And Rossi’s US backer and licensee, Tom Darden – who has a long track record of investment in pollution-reducing industries – has been increasingly willing to speak out in support of the LENR technology field. If you do think that – at least, if you think it without having studied the evidence for yourself – then your reaction is a symptom of the reputation trap. Cold fusion, or low-energy nuclear reaction (LENR), is potentially an inexhaustible source of clean energy. Both reports claimed levels of excess heat far beyond anything explicable in chemical terms, in the testers’ view. (A full transcript is accessible here.) ‘Pleasant is it to behold great encounters of warfare arrayed over the plains, with no part of yours in the peril,’ as Lucretius put it. Experiments such as those of Fleischmann and Pons claim to measure heat deuterium are [2]: If fusion does occur, then by the second The Coulomb energy associated with repulsion is then of the order of MeV. The neutrinos were scratched from the race, when it became apparent that someone on OPERA’s team of respectable scientists had failed to tighten an optical lead correctly. Cold fusion is basically just nuclear reactions at reasonably normal temperatures and pressures. ‘If there is something scientists fear, it is to become like pariahs’. It is a rejection of Vague. Never a good idea. They help to maintain the stability important to what Kuhn called normal science – the ordinary, useful kind of science when paradigms are not under threat. Also, it should be done with fairly simple equipment, another thing that a particle accelerator isn't. The reasoning is still entirely circular, but the reputation trap gives its conclusion a convincing mask of respectability. However, pressing hydrogen together hard enough to fuse it is very difficult, especially considering that the more you succeed, the bigger an explosion you’ll have. Blaming large energy corporations is the cowards excuse for why his/her favorite perpetual motion device won't work. [1,2] Palladium is a very good at Put this way, it is easy to see an argument that we’ve been shooting ourselves in the foot. Theoretically cold fusion is impossible according to the principles of Quantum Mechanics, the reason why the physicists refuse to accept the occurrence of the phenomenon. The problem is to find a way to tap it. It’s like saying “God” is impossible, without having a clear idea of what “God” is. As I said at the beginning, what physicists actually say (in my experience) is that although LENR is highly unlikely, we cannot say that it is impossible. It’s still conceivable that there is fraud involved, as many skeptics have claimed; or some large and persistent measurement error. Meanwhile, a handful of leading theoretical physicists rejected the notion that cold fusion is physically impossible. ), Darden’s attitude displays the cautious open-mindedness that has been lacking in reactions to the field for most of its history. A few other physicists, including the late Sergio Focardi at Bologna, claimed similar effects with nickel and ordinary hydrogen. We should certainly be very cautious about such surprising claims, unless and until we amass a great deal of evidence. I … are in contrast on the order of meV. ‘If there is something scientists fear, it is to become like pariahs,’ as Lundin puts it. reproducibility rate of such solid state cold fusion experiments is at a [1]. (Energy Catalyser). Twenty years ago the process of cold fusion was heralded as the future of creating electrical power. If I’m right, then in a more rational world, we would fix our scientific norms to escape it. What if we already knew, on theoretical grounds alone, that cold fusion was impossible? First and most important, the claim was not easy to replicate. It is very hard to extract from this history any satisfactory justification for ignoring recent work on LENR. You can see why I’ve been salivating at the thought of my dinner. These included Nobel Prize-winner Julian Schwinger, Peter Hagelstein (made famous by his work on the X-ray laser) and the well-known quantum physicist Giuliano Preparata. Why hasn't nuclear fusion been possible on earth yet? The “cold fusion” hypothesis, launched in 1989 by Stanley Pons and Martin Fleisch­mann—two electrochemists who detected excess heat when exposing deuterium to a palladium catalyst—was at that time rapidly debunked by the established physics community, who could not find any of the typical traces of nuclear fusion in the Pons and Fleischmann setup. The energetics - for two deuterium nuclei to fuse, they must come within nuclear distances of each other. other rights, including commercial rights, are reserved to the It’s like saying “God” is impossible, without having a clear idea of what “God” is. We will try and respond to your request as soon as reasonably practical. However, the film had a poor reception, described as "appallingly unfunny". They put their reputations at risk by doing so. Why were these claims so improbable? [1] Today, cold fusion is considered as a originally appeared on Quora: the place to gain and share knowledge, empowering people … A 1990 Michael Winner film Bullseye!, starring Michael Caine and Roger Moore, referenced the Fleischmann and Pons experiment. Authors who do put their head above the parapet are ignored or rebuked. deuterium nuclei can undergo fusion. That’s how the trap works. have enough kinetic energy to overcome Coulomb energy barriers and From the Perez-Simon Collection/Wikipedia, . (Indeed, as my physicist friend rightly points out, it might be disastrous in the case of LENR itself, if it turns out to generate its own extreme risks. experiments claiming to observe cold fusion. is Bertrand Russell Professor of Philosophy and a fellow of Trinity College at the University of Cambridge. [1], Lack of gamma rays produced - The final Not “room temperature,” this is a hot fusion project. fusion reactions with the largest cross sections for heavy water is performed using a palladium cathode. A2A. Currently, the The problem with cold fusion is not that it is theoretically impossible, but that it has not been demonstrated consistently in experiments. Instead of needing to reach temperatures of millions of degrees, cold fusion -- recently rebranded as LENR (Low-Energy Nuclear Reactions) -- is the idea that these fusion reactions can … The author grants There were two reports (in 2013 and 2014) on tests of Rossi’s device by teams of Swedish and Italian physicists whose scientific credentials are not in doubt, and who had access to one of his devices for extended periods (a month for the second test). The author warrants that the Imagine that someone had a working hot-fusion reactor in Florida – assembled, as Rossi’s 1MW device is reported to be, in a couple of shipping containers, and producing several hundred kilowatts of excess power, month after month, in apparent safety. temperatures. This is where, from a philosopher of science’s point of view, things get interesting. What we drink now is slowly killing us. In this case, the author of the article is blithely reproducing the orthodox view, even in the lead-in to his interview with Darden – who tells him a completely different story, and has certainly put his money where his mouth is. This attitude could be disastrous in other cases, if the ideas stuck in the trap happened to be the key to addressing some potentially catastrophic risk. I’ve met scientists employed as technology forecasters for a very large enterprise, who were frustrated at their inability to persuade their organisation to list LENR as a technology of possible strategic interest, even with low probability.
