A few years ago, David Goodstein of Caltech wrote an interesting look back at cold fusion. It's available here: <a href="http://www.its.caltech.edu/~dg/fusion_art.html" rel="nofollow">http://www.its.caltech.edu/~dg/fusion_art.html</a><p>Where the story left off, there were a few competent researchers with well-designed experiments that were getting indications that <i>something</i> was happening that was not covered by current theory. However, cold fusion research was by then out of fashion, and no one was interested in looking deeper into those results and confirming or refuting them.<p>As Goodstein notes, "What all these experiments really need is critical examination by accomplished rivals intent on proving them wrong. That is part of the normal functioning of science. Unfortunately, in this area, science is not functioning normally. There is nobody out there listening."
