Cold fusion refers to nuclear fusion of atoms at conditions close to room temperature, in contrast to the conditions of well-understood fusion reactions such as those inside stars and high energy experiments. Interest in the field was dramatically increased on March 23, 1989 when Martin Fleischmann, then one of the world's leading electro-chemists,[1] and Stanley Pons reported that they had produced fusion in a tabletop experiment involving electrolysis of heavy water on a palladium (Pd) electrode.[2] They reported anomalous heat production ("excess heat") of a magnitude they asserted would defy explanation except in terms of nuclear processes. They further reported measuring small amounts of nuclear reaction byproducts, including neutrons and tritium.[3] These reports raised hopes of a cheap and abundant source of energy.[4]

Enthusiasm turned to skepticism as replication failures were weighed in view of several reasons cold fusion is not likely to occur, the discovery of possible sources of experimental error, and finally the discovery that Fleischmann and Pons had not actually detected nuclear reaction byproducts.[5] By late 1989, most scientists considered cold fusion claims dead,[6] and cold fusion subsequently gained a reputation as pathological science.[7] However, some researchers continue to investigate cold fusion,[6][8][9][10] and some have reported positive results at mainstream conferences and in peer-reviewed journals.[11][12] Cold fusion research sometimes is referred to as low energy nuclear reaction (LENR) studies or condensed matter nuclear science,[13] in order to avoid negative connotations.[14][15]

In 1989, the majority of a review panel organized by the US Department of Energy (DOE) found that the evidence for the discovery of a new nuclear process was not persuasive. There have been few mainstream reviews of the field since 1990. A second DOE review, convened in 2004 to look at new research, reached conclusions similar to the first.[16]
