"Tabletop" Fusion Researcher Committed Scientific Misconduct 161

Geoffrey.landis writes "A Purdue University panel investigated allegations against nuclear engineering professor Rusi Taleyarkhan, finding that he had in fact committed scientific misconduct in his work. Taleyarkhan had published papers in which he reported seeing evidence of nuclear fusion in the collapse of tiny bubbles in a liquid subjected to ultrasonic excitation — a finding that would be groundbreaking, if true, but one that apparently could not be replicated by other researchers. The allegations against Taleyarkhan were made in March of 2006. A local Indiana paper gives the full list of allegations against Taleyarkhan, and the resolution of each by the panel. The full report (PDF) is also available. Of the nine specific allegations, only two were found to comprise scientific misconduct. The committee 'could not find any other instances of scientists being able to replicate Taleyarkhan's results without Taleyarkhan having direct involvement with the experiments,' but notes that this comes 'just short of questioning whether Taleyarkhan's results were fraudulent.'" We've discussed this gentleman's work and the scrutiny it has received several times, and members of the scientific community seem to have given him the benefit of the doubt in many cases.

      The bubble itself is a quite interesting phenomenon, thought it is most likley not fusion as Taleyarkhan claims.

      For those not familiar of Taleyarkhan and the issue of the bubble this is a good BBC video [google.com] I saw a while back on the who topic and controversy. Either way the bubble was discovered by someone else and I personally think should be investigated for other properties other than table top fusion.

      You don't need future tech to give the middle finger to the Middle East - you can do it now.

      One way you can reduce the Middle East's influence is to drive down the value of oil and you can do that by switching your car to natural gas. There are several companies like this one [cngoutfitters.com] that will sell you a kit to make the switch. Googling "cng conversion kits gas" brings up a host of sources.

      Since natural gas is not taxed as heavily and demand is lower, a gallon-equivalent of natural gas costs about half what gasoline costs. The conversion kits allow you to choose between natural gas and gasoline so if you're somewhere you can't find a natural gas station, you can switch back to gasoline. If you there isn't a natural gas station near where you live, you can install a natural gas compressor [myphill.com] in your garage that'll fill your car overnight. The downsides are you lose some trunk space to the extra tank, natural gas stations aren't as numerous as gasoline stations and since methane doesn't store as many calories as gasoline, you lose about 10% of your engine's power. For me, the later issue isn't a big deal since my car has more power than it needs to get me around.

      Natural gas is domestically produced and there's enough of it to last 100 years and that's not counting the undersea hydrate fields. I'd rather burn domestic gas than give Al-Qaeda a cut of every dollar I spend on gasoline.

      To be honest there's no real reason to think fusion would be cheaper than coal, and nuclear fusion isn't much different to nuclear fission in most practical regards. It would be more like an improved form of nuclear fission than a revolutionary new technology.

      Fusion (in the most viable tokamak form) does produce radioactive waste products because of all the neutron flux, but (like lots of forms of fission) the waste isn't dangerous in the long-term. I also haven't seen any real data on how much fusion would cost on a practical level.

      So I don't see why fusion should be treated as anything more than a possible improvement to fission in the future; why aren't we going for fission as the technology to free us from the Middle East in the meantime?
      That's what the US did last time there was an oil crisis, and it worked out well, but this time our reactors are much better and safer for the experience.

    There was a TV programme on this guy a couple of years ago. No other scientists were able to duplicate his work so as part of the investigation the TV production company gathered together the finest fusion scientists they could find and they tried one last time to duplicate the experiment. Although Rusi Taleyarkhan agreed to interviews he refused point-blank to take part in the on camera experiment and (surprise surprise) there was no evidence of fusion.

      NB: The following is more about the quality of the TV show than any attempt to wish away the apparent irreproducability of Taleyarkhan's results so that we can all have Mr Fusions for Xmas.

      If I believed in Taleyarkhan, that TV program certainly wouldn't have changed my mind. The scientist conducting the experiment appeared to be an outspoken critic of Taleyarkhan and we (the audience) had to accept his word that differences in equipment c.f. Taleyarkhan's experiment were inconsequential. As far as I remember, the originally stated purpose of the experiment was to check if the neutrons detected were in sync with the flashes from the bubbles (something not shown in T's results). We were told at the end that the experiment had failed, but with little explanation as to how (no flashes? no neutrons? not in sync? the first two of those would not have been "as was to be demonstrated").

      As for Taleyarkhan attending the experiment, why would he do that? If he'd participated in any way, it would have destroyed the independence of the test.

      ...which was a pity, because in an earlier show they gave the same treatment to a test of the "memory of water" theory beloved of homeopathic medicine: in that case the experiment was presented beautifully, from the careful setting up of independent, blind tests through to analysis of the results for statistical significance. One of the best science documentaries I've seen.

      The "desktop fusion" show was not up to the same standard.

  • It's amazing how many tabletop cold fusion experiments [wikipedia.org] have attracted public attention, and all turned out to be fraudulent when they claimed to have started nuclear reactions. The worldwide large-scale not-so-cold fusion project ITER [iter.org] has just started, with an estimated cost of 5bn EUR, and there are still guys out there trying to outsmart them on a tabletop and some cookbook chemistry.

    I see two possibilities there...

    First, he could have made up numbers. Absolutely unforgivable, and we should all break out the tar and feathers.

    However, if reputable scientists have reproduced his work, even with his direct involvement, then he has accomplished something interesting (even if not necessarily what he believes).
    • What I want to know, given that results have apparently been reproduced with him involved, is what is happening different when the guy is involved? Is something different about his device, his sensing equipment? Does he just like setting up one part at a different angle? Does his body odor involve a strange mutant chemical that effects the results of the experiment? Or is he just really good at making people see what they want to see?

      I have no clue about how the experiment is done, so I don't know what

    It's really frustrating. When Pons and Fleischman originally announced "cold fusion", there was an immediate attempt at Stanford to replicate the result. The researchers gave a talk, which drew hundreds of people. In their first attempts, they had the apparatus surrounded with radiation detectors and alarms, in case there was a sudden burst of radiation. After a while, they realized that wasn't going to happen. The effect, if any, resulted in a few extra neutrons per hour over background.

    They saw some variations in neutron flux, but discovered that people standing around the apparatus affected the result. Humans have lots of water and are neutron reflectors. So they moved the apparatus into a cube of lead blocks. No more neutron emissions.

    Somebody may eventually get fusion this way, but probably won't get out more power than they put in. If you can figure out some way to put a macroscopic amount of energy into a microscopic volume, you can get a little fusion. It's been done with big capacitor banks, with lasers, with explosive compression, and with the Farnsworth Fusor. But far more energy goes in than comes out.

    • Right, the problem with fusion is that it needs to be self-sustaining to be useful. The only way that's going to happen is if the reaction continuously generates enough heat to keep going, which almost certainly requires some significant minimum scale, and makes any sort of tabletop method pretty much impossible.

      I think we'll have real fusion power plants once we figure out how to scale up the current methods enough to be self-sustaining. That's not easy, though, as it amounts to containing a small sun

    Now, I don't want to discount it as snakeoil altogether, but it's one of the fields where a lot of money is pumped into questionable "research". It saddens me that some self proclaimed scientists manage to siphon money away from honest, hard working researchers by producing spectacular (if only ... ok, I don't find a better word, fraudulent) results that surprisingly nobody can reproduce.

    The committee 'could not find any other instances of scientists being able to replicate Taleyarkhan's results without Taleyarkhan having direct involvement with the experiments'

    The fix for this is very simple. Rename the entire process to the "Taleyarkhan Effect." Taleyarkhan will then be directly involved in every experiment, and the results will be reliably reproducible.

    • yes, and one day we'll have a giant generator with the withered corpse of this taleyarkhan guy embedded in the middle to keep it all going. it'll be dedicated to running the world's largest supercomputer, which in turn would be used solely for running windows 47, codenamed "fuzzball", on bootcamp. it'll be grand!

    Allegation: Taleyarkhan intentionally used data in a paper to a scientific journal that already had been used in another journal written by other authors.

    Conclusion: While Taleyarkhan broke copyright laws, the authors agreed to share the data and have not claimed plagiarism. This is not research misconduct.

    In fact, there is no copyright in data (that is, in the facts); actually, using data published by others is a hallmark of scientific progress. That's why they published the data in the first place. If he had claimed the data as his own it would be scientific misconduct; if he failed to attribute the data to its authors it would be scientific misconduct. But there is no way for him to break copyright laws by publishing facts that were generated by others. In fact, even if he used the author's actual graphs and tables (which may be copyrighted), it is not so obvious that he actually broke copyright laws -- scientific use (with attribution) may very well come under the defense of fair use. We are seeing here the results of the propaganda campaign to extend copyright beyond all bounds.

      It helps to read the report. Attribution was missing, that was the whole point of this allegation.

      • by pavon ( 30274 )

        That would just be plagiarism not copyright infringement. Nothing about copyright law or fair use requires you to attribute the work. Which is exactly what the parent post said - that the panel was right in calling it potential scientific misconduct*, but wrong in calling it copyright infringement.

        * just potential because he did have permission to use the data and the team hasn't complained about not be attributed.

    • The point of copyright (nowadays) is to control what information people are allowed to think and share, for the benefit of the few. Including data and facts is the natural next logical step, unfortunately.

  • If you look up "Bubble Fusion" on Wikipedia, you'll see that there have been replications. Perhaps not convincing enough replications to change people's minds, but there does seem to be something interesting enough going on with the collapsing bubbles to warrant further investigation. I'm concerned that everyone who makes a claim that could revolutionize energy production finds themselves facing attempts to destroy their reputations. What kind of environment is that to perform science in? If you follow the

I was in graduate school at the time P&F released their preprint and it was a very exciting time. That preprint flew around the world via fax machines very quickly (if I can dig, I should still have my nth-generation copy) and it was all you heard in the hallways.

  • Strikes me as odd that one one has tried to implement a plasma wakefield accelerator in a configuration that would fuse hydrogen.

  • This seems like the typical gut reaction of any society who doesn't understand a new theory or technology. I can't count or list how many different discoveries have had this same reaction by both the scientific community and the public. Galileo comes to mind. It is likely that only after this guys death will they really discover what his work meant. Sounds like some serious penis envy in the scientific world.

    This is exactly what is wrong with our world.

  • Is it me, or does everyone that seems to make some progress involving cold fusion is accused of faking results and scientific misconduct? Is this kind of behaviour normal?
  • Wait - I've seen this one before, it's a bad Keanu Reeves movie called Chain Reaction, where they get a type of fusion system working (iirc was fusion), but is sabotaged because it would cause the world economy to collapse as oil wouldn't be needed...

    Summary: of course it's a false claim - Keanu Reeves is supposed to do that!
