[en] Since March 1989 when Professors Stanley Pons and Martin Fleischmann made their dramatic announcement regarding the production of excess heat from their heavy water electrolysis experiments, using a palladium cathode and platinum anode in a simple calorimeter, there have been numerous attempts to repeat their work in laboratories throughout the world. Many of these attempts have failed, or produced ambiguous results, but some have appeared to be successful. The Third International Conference on Cold Fusion, held in Japan, October 1992, provided an ideal opportunity to review the present status of work on this topic. Fleischmann and Pons postulated a nuclear fusion explanation to account for their results, presumably involving deuterons, and research work has been devoted both towards verifying the excess heat effects and to identifying nuclear particles produced by these systems. As a result of the adverse publicity given to the early work, most of the later work has been underfunded or performed in investigators' spare time, and as a result sometimes lacks thoroughness. There have been some notable exceptions, however, and some of the presentations at this conference represented work which had been very carefully executed. Results described included evidence for excess heat, and for nuclear particle and helium production. (author)
