    In the last year or two I read an online science article that speculates the light is caused by the bubble becoming so highly compressed and reaching such a high temperature (apparently during the peaks of the ultrasonic wave - the frequency is tuned to the resonant frequency of the beaker, which then focuses all the acoustic energy into a point in the center) that for a brief moment nuclear reactions take place. But last I read this is yet to be verified.

    After writing the above (I'd rather just correct it than rewrite it) I did some online research: Nuclear reactions are NOT suspected as the source of light, but it is believed that the setups to make sonoluminescence can momentarily achieve the temperature (a million degrees) and pressure required for fusion.

    Here are two relevant links:

    It's nothing like the Pons and Fleischmann style cold fusion and has NO relation to it.

    They agreed to review it, and the composition of the reviewers was understandably nuclear physicists... many of whom are deeply in hot fusion research. That means they stand to lose a lot by CF's successes.

    Whether or not there is enough excess heat to be useful is one question. Whether there is nuclear transmutation is yet another. I've spent the past year doing research with Steven Jones at BYU, and in surveying the literature and conducting our own experiments, we've seen some very intriguing results. Sr + d -> Y, Zr, Mo. If you look at Japanese research, Iwamura has had Cs -> Pr, which is a rare earth and you DON'T get Cesium dropping in proportion to Pr's increase by any sort of environmental contamination. Especially not when it's in a sealed vacuum chamber with d2 gas permeation through the metal complex (Pa, CaO) the Cs is deposited on.

    There's data from a Japanese researcher (Ikegami) in Sweden (University of Uppsala) who has found that with deuterium ion beams at various target metals, the nuclear cross sectional area for capture increases dramatically at 10 keV and just gets larger the lower you get. He wasn't even doing CF research, but it's quite interesting to see that you don't require enormous energies in order to achieve d+Z transmutation.

    Perhaps at this point it would be smart to realize that foreign researcher are leaving us in the dust. Myself, I have real doubts about the usefulness of any supposed excess heat, but low energy nuclear transmutation has a lot of intriguing stuff. At the very least, we need to look at the effect of electronic structures in metal lattices on the coulomb barrier for d+Z reactions. In Iwamura's experiments, for example, he got null results when he did it without CaO, when he used H2 instead of D2, etc. What did the addition (in thin film deposition) of an impurity like CaO do to enable a reaction that straight palladium couldn't do?

    Anyway, yeah, there's SOMETHING going on.

      Uh ? Nuclear fusion is interesting, but the basic mechanisms are known. Right now it's more R&D than fundamental research - frontier of technology more than frontier of science.

      OTOH, whoever comes first in actually demonstrating cold fusion will probably set the new record for the quickest Nobel prize ever (remember, Nobel prizes can be awarded to a maximum of 3 persons, and Fleischmann and Pons had the good taste of being only two - leaving one slot open for scientific sainthood)

      If any of these scientists had felt that cold fusion was not merely a possibility, but something real that only waited for careful scientific handling, they would have left their current activities at once !

      The gist of this report is that, essentially, we're not really sure what happens in "cold fusion" experiments, and we're definitely not certain that it is actually fusion, but the results, although unclear, justify that "cold fusion" be readmitted within the realm of real science. The redemption period that followed the Fleischmann and Pons debacle (as described in "Voodoo Science", which should be mandatory reading for any /.er) is over. Good for everyone.

    Sound barrier:
    "The term sound barrier is often associated with supersonic flight. In particular, "breaking the sound barrier" is the process of accelerating through Mach 1 and going from subsonic to supersonic speeds. The term originated in the 1940s when researchers discovered a large increase in drag that seemed to indicate that an infinite amount of thrust would be needed to fly at the speed of sound. In other words, some believed that a physical barrier existed that would prevent an aircraft from ever being able to travel at supersonic speeds. Since there obviously is no such barrier, the term sound barrier is outdated and really should not be used any more. Nevertheless, it has become a popular part of the human language, and continues in use."

    Obviously the people who believed this were using flawed methods of reasoning. However, claiming there were none who thought this way is simply denying history. The Wikipedia article has a good synopsis. Yes the fact that bullets were known to travel at supersonic velocities should have clued these people in as to the errors in their equations. Unfortunately, as I mentioned in another reply, scientists sometimes choose to ignore factual data that contradicts their preferred theories.

    Science is ideally ground-up observation, hypothesization, experimentation, observation and so on. However, if some "ideal" factoid is intruded into the process, it can convert the lazy and unimaginative worker from a properly scientific sceptic to an authoritarian priest of current dogma.

    Once this happens the only means of progress is by waiting for the old guardians of the faith to die of old age, or by shooting them earlier. The "sound barrier" had the magical authority of an equation behind it, "natural law" expressed in mathmematics. Given the ritual efficacy of a mathematical equation at freezing thought processes, it's a wonder we aren't STILL flying at less than the speed of sound. Actually, I suppose that generally we still are, but we know we don't have to.

    Similar situations have occurred repeatedly in science. It's why we actually need crackpots. Occasionally the effort of debunking them can open up entire new vistas.

  33. Half the reviewers found the studies convincing. by Anonymous Coward · · Score: 3, Interesting
    A break down for those who didn't read the article. . .

    There were no new experiments done. Scientists selected by the Department of Energy simply did a peer review of several experiments which had been done over the past ten years by various labs.

    18 scientists were selected to review the collected studies.

    According to the report. . .

    "Evaluations by the reviewers ranged from: 1) evidence for excess power is compelling, to 2) there is no convincing evidence that excess power is produced when integrated over the life of an experiment. The reviewers were split approximately evenly on this topic. Those reviewers who accepted the production of excess power typically suggest that the effect seen often, and under some understood conditions is compelling. The reviewers who did not find the production of excess power convincing cite a number of issues including: excess power in the short term is not the same as net energy production over the entire time of an experiment; all possible chemical and solid state causes of excess heat have not been investigated and eliminated as an explanation; and the production of power over a period of time is a few percent of the external power applied and hence calibration and systematic effects could account for the purported net effect."

    So basically, the jury is split. And if the DOE's sampling of experts is a fair yard stick, then it would seem that when the question is put forth, about half the scientific community would say that there is compelling evidence supporting Cold Fusion. --And given the massive bias and fear related with the subject, (where scientists do not want to be associated with unpopular theories for fear of losing their jobs and professional credibility), the results of this peer review are especially intriguing.

    In any case, this is a rather different picture than the one usually painted around here where most Slashdotters foam at the mouth and yell absurdities about it being impossible to get something from nothing, despite the fact that there was never once made any such claim regarding Cold Fusion.

    (1) The existence of a physical effect that produces heat in metal deuterides. The heat is measured in quantities greatly exceeding all known chemical processes and the results are many times in excess of determined error using several kinds of apparatus. In addition, the observations have been reproduced, can be reproduced at will when the proper conditions are reproduced, and show the same patterns of behavior. Furthermore, many of the reasons for failure to reproduce the heat eect have been discovered.

    (2) The production of 4He as an ash associated with this excess heat, in amounts commensurate with a reaction mechanism consistent with D + D 4He + 23.8 MeV (heat).

    (3) A physical eect that results in the emission of: (a) energetic particles consistent with d(d,n)3He and d(d,p)t fusion reactions, and (b) energetic alphas and protons with energies in excess of 10 MeV, and other emissions not consistent with deuteron-deuteron reactions.

    As a former (hot) fusion researcher, I have to comment on this. No one that I have worked with has been dismissive of cold fusion efforts. Highly skeptical, yes. But not dismissive. The prevailing thought is that calorimeters can lie -- there can be unforseen chemical reactions at work. But if you can measure neutrons of appropriate energy (or other fusion products, depending on the reactants) then some nuclear reaction must be taking place.

    That said, I don't believe that any hot fusion scientist fully trusts the methods of the cold fusion researchers. The cold fusion concepts don't mesh very well with the proven hot fusion body of knowledge. BUT - show me some neutrons and I'll consider almost anything.

    Oh, and having also worked on sono-fusion, yes there was (and still is) a lot of controversy simply because the neutron yields were so low (little above background). But again, that controversy is giving way as more data is taken.
