====Events preceding announcement==== [[File:Cold fusion electrolysis.svg|thumb|Electrolysis cell schematic]] [[Martin Fleischmann]] of the [[University of Southampton]] and [[Stanley Pons]] of the [[University of Utah]] hypothesized that the high compression ratio and mobility of [[deuterium]] that could be achieved within palladium metal using electrolysis might result in nuclear fusion.{{sfn|ps=|Fleischmann|Pons|1989|p=301}} To investigate, they conducted electrolysis experiments using a palladium cathode and heavy water within a [[calorimeter]], an insulated vessel designed to measure process heat. Current was applied continuously for many weeks, with the [[heavy water]] being renewed at intervals.{{sfn |ps= |Fleischmann |Pons |1989 |p=301}} Some deuterium was thought to be accumulating within the cathode, but most was allowed to bubble out of the cell, joining oxygen produced at the anode.{{sfn |ps= |Fleischmann |Pons |Anderson |Li |1990}} For most of the time, the power input to the cell was equal to the calculated power leaving the cell within measurement accuracy, and the cell temperature was stable at around 30 Β°C. But then, at some point (in some of the experiments), the temperature rose suddenly to about 50 Β°C without changes in the input power. These high temperature phases would last for two days or more and would repeat several times in any given experiment once they had occurred. The calculated power leaving the cell was significantly higher than the input power during these high temperature phases. Eventually the high temperature phases would no longer occur within a particular cell.{{sfn|ps=|Fleischmann|Pons|Anderson|Li|1990}} In 1988, Fleischmann and Pons applied to the [[United States Department of Energy]] for funding towards a larger series of experiments. Up to this point they had been funding their experiments using a small device built with $100,000 [[Out-of-pocket expenses|out-of-pocket]].{{sfn|ps=|Crease|Samios|1989|p=V1}} The grant proposal was turned over for [[peer review]], and one of the reviewers was [[Steven E. Jones|Steven Jones]] of [[Brigham Young University]].{{sfn|ps=|Crease|Samios|1989|p=V1}} Jones had worked for some time on [[muon-catalyzed fusion]], a known method of inducing nuclear fusion without high temperatures, and had written an article on the topic entitled "Cold nuclear fusion" that had been published in ''[[Scientific American]]'' in July 1987. Fleischmann and Pons and co-workers met with Jones and co-workers on occasion in [[Utah]] to share research and techniques. During this time, Fleischmann and Pons described their experiments as generating considerable "excess energy", in the sense that it could not be explained by [[chemical reaction]]s alone.{{sfn|ps=|Fleischmann|Pons|Anderson|Li|1990}} They felt that such a discovery could bear significant commercial value and would be entitled to [[patent]] protection. Jones, however, was measuring neutron flux, which was not of commercial interest.{{sfn|ps=|Crease|Samios|1989|p=V1}}{{clarify|date=November 2015}} To avoid future problems, the teams appeared to agree to publish their results simultaneously, though their accounts of their 6 March meeting differ.{{sfn|ps=|Lewenstein|1994|pp=8β9}}
