Twenty years to the day that two electrochemists ignited controversy by announcing signs of cold fusion at an infamous press conference in Utah (watch a video of the 1989 event), a separate team has made a similar claim in the same US state. But this time, the evidence is being taken more seriously.
Back in 1989, Martin Fleischmann and Stanley Pons at the University of Utah announced the tantalising prospect of abundant, almost-free energy, but their claims of fusion reactions in a tabletop experiment were dismissed by nuclear physicists, not least because such reactions normally occur inside stars. The small quantity of extra energy they found was widely considered a fluke or the result of experimental error.
Now Pamela Mosier-Boss and colleagues at Space and Naval Warfare Systems Command (SPAWAR) in San Diego, California, are claiming to have made a "significant" discovery – clear evidence of the products of cold fusion.
On 23 March, the team presented its work at the American Chemical Society's spring conference in Salt Lake City, Utah, a few months after the study was published in a peer-reviewed journal (Naturwissenschaft, DOI: 10.1007/s00114-008-0449-x).
