Not sure about that. Those particles can be convoluted. The wires are also convoluted. After Celani treats them, they are full of holes, like Swiss cheese. I suppose it would be difficult to estimate how much surface area there is, taking into account the inside surface of those holes. After a while it resembles Mandelbrot's famous question "how long is the coast of Britain?" The answer is light-years long if you measure it on a small enough scale. See: http://en.wikipedia.org/wiki/How_Long_Is_the_Coast_of_Britain%3F_Statistical_Self-Similarity_and_Fractional_Dimension I think that it is interesting that a quick calculation of the power output > of a roughly Rossi sized collection of particles came within the ballpark > of his claims using information obtained from Celani's experiment. > That is interesting. I have felt for some time that Rossi may not have such a huge breakthrough. He might just have a lot of powder, with a lot of surface area. Arata and the others in Japan are using a tiny amount of powder. If they were to use more they might get Rossi-like results. - Jed
