Dennis Cravens and I think that one of the reasons the Rossi experiment works well is because he uses a large volume of material. We think the effect might increase exponentially with with increased surface area. This may be one of the "secrets," which is sitting in plain view.
In his blog, Rossi remarked that he is making a large system by ganging together 100 smaller 1 L cells because he might have trouble controlling a larger, 100 L cell. That tells me volume is an important controlling parameter. I recommend that people attempting to replicate this experiment should use a larger volume of material than most cold fusion experiments. Perhaps I feel this way because I've always wanted to see researchers scale up a little, even though there is no technical justification for it. - Jed
