 In 1989, Pons and Fleischmann submitted papers to the "Journal of Electroanalytical Chemistry" claiming that they had observed fusion in a room temperature device and disclosing their work in a press release.Some scientists reported excess heat, neutrons, tritium, helium and other nuclear effects in so-called cold fusion systems, which for a time gained interest as showing promise.Hopes fell when 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.
