Typical real cold fusion excess heat looks like this: http://www.lenr-canr.org/acrobat/DardikIprogressin.pdf
See: "Exp. # 64a . . . Excess Power of up to 34 watts; Average ~20 watts for 17 h" This is also how Ni-H cold fusion looks. Perhaps Celani has discovered a particularly stable form of cold fusion. Frankly, I doubt it, but I am only guessing. In past cases I recall, stable reactions that look like this all turned out to be artifacts. - Jed
