Cold Fusion Gets a Boost From the US Navy

Posted by kdawson on Sun May 06, 2007 04:50 AM
from the fuse-this dept.
Tjeerd writes in to alert us to the publication in a highly respected, peer-reviewed journal of results indicative of table-top fusion. The US Navy's Space and Naval Warfare Systems Center in San Diego, CA (called Spawar) has apparently been conducting research on "cold fusion" since the days of the discredited report of Pons and Fleischmann. They are reporting on the reproducible detection of highly energetic charged particles from a wire coated in palladium-deuterium and subjected to either an electric or a magnetic field. Their paper was published in February in the journal Naturwissenschaften (which has published work by Einstein, Heisenberg, and Lorenz). New Scientist also has a note about the fusion work but it is available only to subscribers.

[+] Hardware: New 'Stellarator' Design for Fusion Reactors 171 comments
eldavojohn writes "The holy grail of fusion reactors has always seemed 'just a few years off' for many decades. But a recent design enhancement termed a 'Stellarator' may change all that. The point at which a fusion reactor crashes is when particles begin escaping due to disruptions in the plasma. A NYU team has discovered that coiling specific wires to form a magnetic field may contain the plasma. This may be a a viable way to create a plasma body with axial symmetry, and a far better chance of remaining stable. Like other forms of containment this does require energy itself, but could bring us closer to a stable fusion reactor. It may not be cold fusion or 'table top' fusion but it certainly is a step forward. The paper is up for peer review in the Proceedings of the National Academy of Sciences."

      There's a huge difference between mere fusion reactions and an actual fusion reactor that will sustainably produce power. From what I've read, this is about the former, so I'm not keeping my fingers crossed just yet. However, it's still good to see that fusion research is being carried out along several different approaches.
        • At this point, they are not aiming for net energy production. Their two main advances are to 1) use codeposition to get deutrium loading from the beginning and 2) using a detector that can fit within the experiment. The first advance means that the effects are seen just about every time, and the second means that the background has less of an effect on detection, particularly if charged particles are involved since these have trouble escaping the experimental setup owing to Compton losses. Getting more power out than in is not really the basic measure though. The power out so far is heat, so you want quite an excess before you can turn that back into something usable.

        The energy produced per fusion event pretty much has to be the same, but the rate at which the fusion occurs is controled differently. If this can be harnessed for energy production, it may end up as distributed power generation rather than centralized power generation envisioned for hot fusion.

        "Cold" fusion means cold relative to the temperature of the Sun (hot enough to fuse hydrogen). "Cold" fusion in theory could potentially boil water, and drive the turbines. However, a basic quantum physics result is that there is basically no way in heck that cold fusion will ever work, unless there is some new unknown physics taking place. While possible, it's unlikely, which is why most respected journals shy away from it, in addition to the large number of quacks the field has attracted. I put more hope in the Polywell stuff: http://en.wikipedia.org/wiki/Polywell [wikipedia.org]

            Polywell operates by creating a converging potential well of tens of thousands of volts and dropping ions into it. At roughly 11,000 degrees kelvin per electron volt that's one HELL of a hot spot.

            Tens of kilovolts, on the other hand, are easy to handle - in a near vacuum. The trick is to achieve sufficient DENSITY in that near vacuum and keep the particles at that temperature and pressure for enough TIME to end up with more fusion energy harvested than you put in to set uop the system.

        From wikipedia [wikipedia.org]

        In 1991, Eugene Mallove who was the chief science writer with the MIT News office, said that he believes the negative report issued by MIT's Plasma Fusion Center in 1989, which was highly influential in the controversy, was fraudulent because "data was shifted" without explanation, and as a consequence, this action obscured a possible positive excess heat result at MIT. In protest of MIT's failure to discuss and acknowledge the significance of this data shift, he resigned from his post of chief science writer at the MIT News office on June 7, 1991. He maintained that the data shift was biased to both support the conventional belief in the nonexistence of the cold fusion effect as well as to protect the financial interests of the plasma fusion center's research in hot fusion. Also in 1991, Nobel Laureate Julian Schwinger said that he had experienced "the pressure for conformity in editor's rejection of submitted papers, based on venomous criticism of anonymous reviewers. The replacement of impartial reviewing by censorship will be the death of science". He resigned as Member and Fellow of the American Physical Society, in protest of its peer review practice on cold fusion.

        I read the paper. As you note, it is a short communication documenting some observations from an experiment. It does not purport to be a breakthrough, although it does claim that the observations must be due to a nuclear reaction. The discussion clearly states that they have no theory as to the physical mechanism that might account for the observations.

        As an editor or a reviewer, I might well choose to publish a paper -- especially a short paper -- that documented some experimental results, even if the mechanism behind those results was unclear. Maybe there's a future paper forthcoming that either contradicts the results, or offers an explanation, nuclear or not. It makes sense to me to document the alleged evidence in the archival literature.

        I want to repeat that the conclusions of the paper are very weak. The outrageous claims have been added later by the popular press. And the argument that "Einstein published there 100 years ago, so it must be true" is unworthy of repetition or rebuttal.

The best place to visit for an overview of the field is http://www.lenr-canr.org/ [lenr-canr.org].

    Though the experiments are remarkable, no concensus on the theory has emerged yet.
