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.

I am retired now, but back in the day, I spent a lot of time studying the channeling phenomena of MeV alpha particles in single-crystal silicon. The channeling phenomena widens and becomes less pronounced as you decrease the incident particle's energy. It often struck me that if you aligned a single crystal substrate with a low-energy deuterium beam the beam would be focused to the center of the channel. as the deuterium piled up in the center of the channel the incident beam would be focused on that deuterium, effectively "Increasing" the d-d cross-section. It seems to me that an optimum energy and crystal substrate could be found to get a enhanced reaction going. There are some other tricks with two crystals you can do, but I digress

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.

The problem isn't really in science. REAL scientists (I'd say the majority of them at least) never claim to have "full knowledge" of anything, and are very much aware of the gaps and vast areas uncharted. They are even afraid sometimes to get to these vast uncharted areas in their research. The problem is with the billions of ignorants who MUST have something to believe in, and with the decline (in popularity) of religion, have made the scientist figure (yes, the one with strange hair-cut and white apron, holding glass test tubes and colorful liquid in them) their new high priests, doing the rituals of the new religion. True, we owe much of modern day's technology to the findings of scientists, still... the masses put way too much faith on the scientific method and "what we know at present" for their own health. I think the strongest example is the huge political force on scientists today to align with the new prophetic warnings of "global climate catastrophe" which is of course a big fat lie - there's absolutely no evidence, or even reasonable model to predict that. Anyway - the workings of religion severely damage scientists ability to do their thing successfully.

Stanley Pons introduced cold fusion to the American Chemical Society in Dallas in 1989. It was very exciting. Later attempts to replicate were like trying to play basketball when the air goes out of the ball. One person at Texas A & M explained that in their further work, when it seemed to work, there was a lot of heat and the palladium rods would distort. And, that pure palladium would not work; it had to have impurities, possibly if i recall 5% platinum. Something was happening, if not cold fusion, but possibly neutron capture? Very obvious is that if we stick to known channels using known paradigms, we will not discover new worlds. Kudos to those who continue this work. Thank you Professor Sabine, for an insightful presentation.

@massmanute Жыл бұрын

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.

Ha! You bring back old memories. I read an article in Popular Mechanics or some similar publication on how to build a crystal radio using galena. A friend of mine was a rock collector and gave me a small crystal of galena. I remember heating a lump of lead with my father's gasoline blowtorch and dropping the crystal in it. Then I needed to make an inductor. It turns out that Quick Quaker Oats came in a cylindrical container of the right diameter. I pestered my mom to make me Quaker Oats for breakfast. When the tube was finally empty, I asked my mom if I could have it. The next problem was finding wire to wind the inductor. It turns out that old power transformers from radio and TV sets had a lot of wire. I used some to make the inductor, and some heavier wire to make the antenna. Now that everything was together I found a sensitive spot on the galena crystal, and lo and behold I heard voices! The signal was much stronger than I expected, so I got on my bike and followed the road down to the end. There sat radio station CFRB, a 50,000 watt station on 1010 kilocycles. The friendly engineers let me in and took me on a tour of the station. I was completely fascinated and returned many times for more explanations of how the station worked. This started a lifelong career in electronics. I am now 80 years old and retired with a total of 6 United States Patents and numerous inventions. All thanks to a small crystal of galena from a friend.

If you bore them to tears, they won't. It really is that simple. Of course, simple is not easy, and finding a good educator is an endlessly frustrating task. During my entire schooling I had... I think two teachers who were both engaging and effective. I had a great one that taught me next to nothing, because he was engaging but not very good at teaching, and none that were great at teaching but not very engaging, because the latter is a prerequisite for the former. Over the course of two decades, that is a very small number.

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.

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.

CF is a catalyzed nuclear reaction that occurs by tunneling. It can be done using any of the D8 transition metals Ni Pd or Pt. The strongest resonance transition is with Pd. What happens is the electrons from the deuterium tunnel to fill the gap 9'10 D transitions giving Pd the configuration of Cd. When this occurs the hydrogen briefly forms an intermetallic alloy that nullifies the space charge. This drags the nuclei within the capture radius via quantum tunneling. A curous effect of this reaction is that it will preferentially create 3He and a free neutron rather than 4He and a gamma ray. It was studied as a potential source of tritium production. The major issue is that the reaction damages the lattice of the palladium partly by mechanical dislocation and partly by activation. The energy isnt enough for serious power generation and is self terminating. The best catalyst for the reaction are carbon nanotubes loaded with palladium nanocrystals in deuterium. Trigger with a magnetic field and an accoustic shockwave. Your choice of matrix deuterium at high pressure, lithium deuteride, or deuterium oxide. The first two options require an explosive to pump it, the last one can be done using ultrasound. With plain D2O you get dim blue flashes in the sonoluminescent cavitation cell, with carbon nanotubes the same but sometimes greenish white, with pd nanocrystals you get blue flashes and occasionally a brighter than normal and while flash. With Pd loaded nanotubes it will make the blue and greenish white flashes and occasionally very bright pinkish white flashes with detectable nuclear radiation both gamma and neutron. 🤓

My guess is that palladium's electronic field properties are connected with why it's such a standard catalyst in so many reactions as well as being useful in rudimentary cold fusion. It seems to me that if we are going to discover a way to generate energy-positive low-gravity cold fusion, we will need to find some way to exploit electron fields in order to breach their repulsive effects. We cannot simply push the nuclei together against the outward electron degeneracy pressure. Converting the electrons into muons is a good example of finding a way around the degeneracy pressure. Apparently palladium has some way of slipping past it as well, and I would wager good money (if I had any) that it's connected to palladium's use as a catalyst. Perhaps research into platinum, another major catalyst, could yield more insight. Maybe we can engineer a metamaterial with far stronger catalytic properties which could assist with the process to a greater degree.

@spvillano Жыл бұрын

The problem of repeatability seems to be reoccurring issue. And that may be due to the ignored non-repeatability of the materials used to repeat the experiments. It is very possible that to repeat the experiment, the confirming/debunking lab needs to use the very same substrate samples that the original labs used to observe the anomalous phenomena. The 'magic' that is being missed might be contained in the rare and fortuitous piece of palladium used in the first experiments. Such debunking/confirming efforts must be done using the same original materials used originally.

I was in grad school (in math) when Fleischmann and Pons made their announcement. Shortly after the announcement, just as cold fusion seemed to be going down the tubes, I was at conference, and a well-known mathematician from the University of Utah (who was good friends with the cold fusion dudes) was there. He was fairly confident that there was something to cold fusion, and that something would eventually come of it. But, the thing that this math guy was most animated about was the way that other scientists reacted to the announcement. He claimed that most of the big researchers working on hot fusion had people present in Utah for the announcement, and that they went to great lengths to denigrate the idea, concentrating their effort on the press. Apparently, the purpose of this was to preserve the funding for hot fusion at all cost. In any case, it's nice to know that cold fusion (i.e., LENR) has made enough of a comeback so that it can at least be studied once again.

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....

Initially, cold fusion results couldn't be replicated because tests were performed by nonbelievers. In fact, where scientists were successful at first, sometimes something "happened" in the lab, signaling that nonbelievers must be present, which somehow stopped the process cold.

I'm glad that there are people out there willing to get their hands dirty and risk their reputation exploring this topic, the potential is so huge that is a shame that there is such a stigma in the science community. Even if the probability is 0.001% for this thing to work, it seems dumb to not spend a few bucks investigating it. Glad Sabine has a positive attitude towards this, who would have thought! 😉

Even if cold fusion doesn't work, the precise mapping of materials properties is worth the investment. Who knows what we can do with this knowledge?

Barely a century ago nuclear physics was an unproven field. Today even minor league physics geeks know the names of the pioneers.

@@NorseGraphic and the more important - it has much more opportunities, areas and directions of study than hot fusion, for which the main and almost only possibilities - is to increase the temperature and the size of the reactor

The same argument can be made for investigating UAPs (UFOs). But...there's just one problem.

Avi Loeb has repeatedly called for more investigation of UFO, same for Michio Kaku

Another gem. Sabine - if you added a tshirt to your store with your image, and the quote "There's just one problem..." I bet it would be very popular!

Forget LENR, we should rename it JOPF, short for "Just One Problem Fusion"

"...by which I mean a PhD in Nuclear Physics will do." Love the snark - this really helps with the discussions as it helps to keep me engaged when Sabine talks about stuff that's nearly always going over my head.

I remember cold fusion coming out in the late 1980's. There was a hard push against it. The same thing happened against Rosse, the Clem engine, etc. And nobody talks about cavitation even though the Japanese have found 10,000 degree spikes. Could it be that the big trees are shading out the seedlings? Yay! We have Sabrine!
