I didn't know that there where some cold fusion that actually works. Even if the current methods is impractical for energy generation it doesn't sound like we have to break a few of the laws of physics to achieve it. So then it worth while to do some research about it.

​@yeroca I worked for a Japanese company and I assure you that English jokes don't translate well. We were on a fast paced project to build and install a machine in 12 months that was the OEM time frame working pretty much around the clock to do it. Well our management (Japanese) wanted to do it faster. I said you can make a baby in 9 months with one woman, but you can't get 9 woman pregnant and do it in one month. Our engineer translator just couldn't translate it, I got our Japanese American secretary explained it to her in English it took her a few minutes and a couple questions to understand it and come up with a translation that got the point that sometimes you just can't accelerate things.

I can’t help thinking, the irony of the blow-up-the-lab argument is that conspiracy theorists will likely miss the point. Instead of proving that you get a lot of energy out, they will likely assume that the lab was deliberately blown up by agents sent by the oil companies or something, to ensure that the experiments are stopped.

I led one of the teams that Sabine cites in this video (at the 10.34 mark). We spent almost five years looking into LENR. In the video, Sabine states that we could not replicate the prior results. That's true, but there’s more to it. We observed the claimed heat effect, both in magnitude and duration, in our parallel *control* cells. This indicates a calibration error in the apparatus. One little known fact about these electro-chemical cell experiments is that they are run for a week or more before the effect is observed. Typically, calibration is conducted over a few hours and is done both before an experimental run and intermittently during it, to re-check thermal stability. We submit that this approach to calibration is inadequate for establishing a calorimeter’s propensity for heat artifacts. Stability over time periods longer than the experiment should be demonstrated in order to minimize the possibility of misinterpreting the fluctuations that we observed as “excess heat” events. Consequently, we contend that all claims of anomalous heat in LENR experiments using electro-chemical cells that do not exhibit thermal stability on a time period longer than the time duration of the experiment itself must be thrown out. As the majority of research over the past 30 years has not demonstrated this kind of calibration stability, that eliminates most of the effort in this field. You can read more about our work on the ReResearch LLC website. That is not to say that we know everything about hot fusion in the solid state or how quantum mechanical interactions might impact fusion reactivity. There is much still to be discovered. But these electro-chemical LENR heat experiments are noise, not signal.

Fascinating! I never knew there had been so much cold fusion in the past. Apart from the science, there is a lot of interesting stuff about the psychology of the scientist. In the early 2000s, there was an initiative entitled Sonofusion (an amusing multiple meaning there) in some way a similar approach to the earlier cold fusion. An acoutic device generated small bubbles which produced a highly localised intense energy pulse when they collapsed. The fluid medium was C3D6O. (en.wikipedia.org/wiki/Bubble_fusion) Scientifically, the credibility was supported by a some very eminent scientists in the field of two-phase flow, experts on everything to do with bubbles.They even did some predictions using models based on the classical gas laws and hydrodynamic equations, which showed pressures high enough for fusion to be credible. There are papers which include it. Isn't that enough to convince sceptics? But there's only one problem. ..... the gas laws and fluid equations dont apply anywhere near those pressures. Re - the reputation trap. Weren't they concerned about their reputations? Oh no, they were well past retirement age, no need to worry about reputation and future career

As an old guy from Utah that remembers the Pons/Fleischmann flash and fizzle news events, I'm glad to hear there is still research going on in cold fusion. It is one of those things that *seems* like it should be feasible and we just need that first breakthrough. We are sort of at that post electric but pre lightbulb era. Where we know enough to conjecture and try out a bunch of things, but it's mostly just guessing from millions of permutations. Once we have a small success, we can focus on a narrower set of parameters.
Lawrence D’Oliveiro
The late Arthur C Clarke believed that cold fusion was real. I remember an interview where he said one of the two guys (Pons or Fleischmann, can’t remember which) was in a secret lab being funded by Toyota or somebody, to continue working on it. Of course, that was decades ago, and nothing much has come out since.

@Jessie Fleischmann Wow! It's a small world. I mentioned that I knew Pons and Fleischmann when I was a post doc at the University of Utah. I once met with the two of them to explain some of my ideas about electrochemistry. The ideas were controversial at the time, and I was having a very difficult time getting them published. The encouraged my to keep trying, and as I was leaving the meeting they made a cryptic comment that they were were working on something that was controversial, but they didn't say what it was. In retrospect their comment had to have been about their cold fusion work, which was not publicly known at the time.

I admire Sabine's commitment to speaking the truth and letting the chips fall where they may. The first time I heard of her was her article in Symmetry Magazine attacking the sacred cow of "beauty" in physics. As a practicing physicist in the US, I can tell you that was an important message that physicists needed to hear. This video may have an even more important message since it address the conformity rampant in all fields of science. I am certainly guilty of thinking cold fusion is a hoax, but I am now willing to reconsider. Thanks Sabine!

@Richard Hussong I am in agreement with Sabine when she suggests Hydrogen power is not a very practical efficient alternative, unless for a government which could not care less about efficiency.

it feels like hot fusion is like using the same technique that everyone uses to jump over a bar, and trying to perfect that, higher and higher but only increasing in height slightly every time. While cold fusion is like someone trying to work on a new jumping technique that would change up the whole sport but they get laughed at because it looks funny.

Gaston Lamaitre Fotografie
When the Pons/Fleischmann article first came out I was studying Physics in Utrecht Uni. At the faculty we spend an afternoon with all present (professors, researchers and students) bombarding a piece of palladium with paricles. If a simple battery could do it, we had stuff that could do it more efficient. But we saw no effect and by the end of the afternoon the consensus was that it doesn't work. As far as we understand physics there is no mechanism to make this happen, nor have we seen any evidence (that is repeatable) to suggest something is going on we don't understand. So until some clear evidence shows up it is whishfull thingking and not science.

As luck would have it, I actually knew Pons and Fleischmann back in the early-to-mid 1980s. I have reason to believe that, based on a cryptic remark the two of them once made to me, I think that they had already started their work on cold fusion at the time they made their remark to me. Martin Fleischmann died a few years ago. The last I heard Pons was still working on cold fusion at an undisclosed site, probably in France. There is another small fusion device called a fusor. It's not exactly cold fusion, but the devices can be quite small. The inventor (or perhaps one of the inventors) of the fusor was Philo T. Farnsworth, who was more famous for inventing television. Farnsworth was my grandmother's second cousin, and I once met his widow at a family party. I am actually in possession of one of Farnsworth's fusors, not the complete device but parts of it. The parts are sitting in my garage. The demonstration a few days ago of hot fusion exceeding the break even point was exciting. There is an old joke about nuclear fusion which goes something like this: practical fusion is just 20 years away, always has been, always will be. I heard that joke about 35 years ago, and it still applies.

Thank you Sabine for a Cool Cold Fusion review! I love your take on it. I remember when I was an undergrad at my community college (College of the Redwoods) in Northern California, in 1989 there was a flare of excitement over Stanley Pons and Robert Fleischman's claims. One of the chemistry professors was like "yeah we've got the equipment, let's take a shot at it..." I got wind of the attempt, and asked to see the professor. I pointed out to him that since we really had no idea what was going on, that potential radiation hazards should be considered. I merely showed him that even a 1 W source of fast neutrons could produce a hazardous situation (a whole class of students getting fast neutron flux seemed to horrify him.) I asked that they slow down, obtain some additional radiation monitoring equipment before they attempt it. The suggestion was well taken, and the first experiment was done with a Geiger counter borrowed from the Geology department, and a closed circuit television system (borrowed from the Media and Broadcast Dept,) and a bunch of plastic barrels full of sand behind a maintenance building. First experiment only elicited a small twitch on the Geiger counter...so it was considered safe enough for the lab... It was just interesting how the Chemistry Dept did not even consider the physics involved in nuclear fusion. Just a little bit of caution....

@Richard Hussong I wish you were around with the group of the Manhattan Project back in the day and sprung that on them. I am sure you would have been met with some quizzical looks. Isn't there a science experiment video on TRvid where one can produce hydrogen from a glass of water, with some batteries, and two metal strips ? I think the result has been replicated., but on a mass scale is a whole different story.
Richard Hussong

Well, to be fair, attempting to replicate a result does not necessarily require considering the theory behind the original experiment.
Lawrence D’Oliveiro
That reminds me that there is one form of fusion that our Dr Hossenfelder doesn’t seem to have mentioned, and that is the Farnsworth Fusor. It was accidentally discovered by American inventor Philo T Farnsworth in the process of his pioneering experiments in making colour TV, when he found out that under certain conditions his apparatus was giving off neutrons. I first heard about this some years ago, when a British schoolboy used this technique to break the world record for the youngest person ever to achieve nuclear fusion. I think they evacuated the whole school during his attempt. (Of course it had to be done in careful coordination with the school authorities...) Again, the energy you get out is way, way less than what you put in. But the whole apparatus is small enough, and the power consumption small enough, that you can conduct the whole experiment on a school laboratory benchtop.

IMO these factors are dimensions of every component because standing waves of various types and sizes will likely play an important role. There will be some clues gained from sonoluminescence.

Thank you for posting this video. When I was 16 I read a book on cold fusion and I have always thought that it was a shame that such an impactful technology was not pursued because of some strange intelligentsia prejudice. I really hope that after these past 25 years and with the current enlightenment of the general public that talks like these will raise interest in the uninformed and bring this hidden gem into light. Thanks again!

Dude. chill. if the energy produced is insufficient to reliably be discerned from background thermal noise, it is a shit idea. Back in the pre electrical days, static electricity could kill small animals and cause painful shocks despite not being understood. thinking this is going to be worthwhile is like thinking power from fireflies is a good idea. You would be living in the dark ages were it not for the intelligentsia.

Thank you so much for the excellent introduction to cold fusion. You understand that there is a missing idea and my theory predicts the answer. Our perspective of FORWARD TIME is actually related to spherical quantum expansion. This implies matter exists in radial trajectories @ c. Think of a proton as a stretched out ball point pen spring. A star is a collection of springs all moving on the same radial...HENCE THEY ARE ALIGNED. We don't understand that Time is a vector of existence and as such, THERE IS A "SHORTEST PATH" THRU TIME! Alignment will be the key to cold fusion. The problem is we can not use Light to determine the "shortest path" we could use relative atomic clocks to experimentally determine the shortest path of time. My cold fusion patent would be for an outer space orbiter that would maintain a long collimator in the correct orientation for fusion. That energy would supply the needs of the orbiter and its fission/fusion reactor. Recycle neutron into heavy matter then break them into E/M BEAM TO EARTH GRID and NEUTRON source for fusion.

This was fascinating. I had previously been under the impression that cold fusion simply doesn't work, but it sounds like it really just has the same problem hot fusion does: taking more energy to cause the fusion than you get out of the reaction. That does make it annoying that it doesn't see research and investment the way hot fusion does.

@Tim, Actually, I was merely attempting a bit of humor. And I was open-minded about cold fusion at the time, particularly because I was already aware of the quiet, largely military-funded research that existed prior to, and continued after, the F/P announcement. There are many areas of investigation that suffer from premature promotion or inappropriate monetization. Homeopathy, for instance, sounds ridiculous and demonstrates nothing more statistically significant than the (very real) placebo effect. But there are a litany of unexplained properties of water that homeopathy has helped to at least raise interesting questions about. The “medicine” is pseudo science, but not everything about it is baseless hucksterism.

And the problem is much worse. Due to the reputational risk, we don't have many scientists entering the field or money being used to investigate it (outside of Japan, initially), or even trying to replicate it. By the way, there were many people who did claim to replicate it, but due to the reputational hit to the field, these people were written off as "true believers" despite their previous experience as scientists. Storms was a good example. It didn't help that the field was also influenced by some folk that did have all the traits of true believers.

@Jonathan Odude All I would like to know if there is good experimental confirmation (peer reviewed, clear enough) that anything nuclear happens in these experiments. That there is (delta)E=(delta)mc^2 kind of energy release and creation of isotopes that were not there to start with in the experiment. If so- then all the power to experimenters. But I'm afraid that we don't have such confirmation(none of cited sources in video). Am I correct?

I was a physics major in College and then I switched EE when a lot of my Physicists friends were getting side jobs in anything they could find. After getting a PhD in EE, I often wondered if I chose the right road. At the time, there wasn't these big species ending problems like Global Warming or Energy Crisis. If there were, maybe I would have stuck it out.

"I suffer from a lifelong allergy to math" You suffer from trauma from crappy teachers, over bearing parents, and a shitty scholastic system. You need to address this trauma and stop deflecting with ridiculous notions like being scared of numbers or having an allergy to maths. Its not kitchy, its not funny, its not a badge of honor, its not a personality quirk. IT IS UNADDRESSED TRAUMA. Stop it. Get help. Also, its not the maths that matter. The concepts are whats important. If you understand the concepts at play you can look up the formula, put it into a spreadsheet, and have the computer do it for you. Just like literally everyone else does. No one is doing polynomials by hand. No one. That belief is a side effect of the trauma your shit school experience left you with. Stop making excuses for the people that have abused you and get over yourself. As someone who taught themselves more than school ever tried to, I know you're traumatized and you need to stop using it as a crutch. No one is going to pat you on the back for it except those who also think themselves cool for being afraid of maths. For the record, none of them are cool.

Interesting, the MIT article referenced at the 13:30 of the video states "the cold fusion claims have been rejected due to lack of plausible explanation". This seems puzzling and not required. As long as an observable response is achieved repeatedly, then it is irrelevant if there is an explanation. There are many things have relied upon for which we didn't have explanation. The concept of gravity was used by humans long before there was an explanation. Having an explanation/theory of operation would obviously help direct further research and optimize results, but again, if a result is repeatable, having an explanation is irrelevant and should not block further investigation into a subject. If it's only randomly repeatable, then research should be focused on making it repeatable/improving it (without the explicit need for understanding as to why, that could come later).

@QuartuvLarry - It wasn't salt water, but collisions that caused this (many cars being slammed against buildings breaking battery seals and busting gas tanks - it's a mess, for sure). EVs, as per insurance companies (they have the best records - fire = big claims, which takes from the bottom line), don't catch fire as much as the media wants anyone to believe - by a factor of around 25, ICEs are worse regarding fires, but, at the top of the list are hybrids - yuk! (the worst of both worlds regarding personal transportation).

COLD FUSION IS POSSIBLE, AND PROBABLY GOING ON IN YOUR COUNTRY. there. no midcareer crisis, replicate it all you want, got my authority stamp on it. just 2 little trivial details, first which is actually trivial for me i'm not *technically* a physicists some would say the university wouldn't replicate that claim... yet. they haven't seen how sharp my knifes are thats all and secondly, maybe it isn't trivial for lesser scientists *my chemist friend frowns as intense hatred of me fills him* but you just need to define the word cold, as our common pixalated friend up there mentioned... but i d go a bit farther, i m planning on specializing in astrobiology so lets dump the bio part, extend the physics in astro, take a very innocent and random sample of our study enviroment (strictly restricted to the observable universe) and... if you're bored and curious enough to have dragged yourself though this nonsense you know where i'm heading, i'll just use my friend Sagitarious's jargon for cold accretion disk, aka UY SCUTI's core temperature, give or take a million kelvin.

I feel that regardless of whether LENR will "save the world" more tenacious experiments by good experimental physicists (or for that matter chemists who really understand physics) will bring out the reasons (Sherlock Holmes like) for the lack of reproducibility in the calorimetric & other measurements & illuminate our understanding of LENR. The history of Science is witness to this. Some other videos on related nuclear/particle physics topics would be appreciated. Thanks a lot SH !

It's going back many years, but I read about cold fusion, not long after it was initially proposed, the article claim that the reason the experiment couldn't be repeated was the fact that the metals used as the anodes/cathodes had microscopic cracks in them, some were produced without these cracks (apparently by happenstance), and these would produce the "cold fusion".
