David Goodstein (physics professor at Caltech) wrote this fascinating article in 1994: http://www.its.caltech.edu/~dg/fusion_art.html http://www.its.caltech.edu/~dg/fusion_art.html. I'm not sure the status of cold fusion research hasn't changed much since then. The major problem of "cold fusion" seems not to be that it the findings aren't reproducible (at this point, they have been reported by several labs), but that they aren't consistently reproducible even with the same apparatus. Without knowing which factors determine whether or not excess heat or neutrons are observed in a cold fusion cell, it's impossible to know whether the observed positive results represent mistakes, methodological errors, or bonafide (albeit intermittent) nuclear fusion.
