I wonder whether a filter could be developed to do a fourier analysis and then partially subtract out predominant frequencies seen during calibration runs. Perhaps something like that could be effective enough to avoid the need for liquid nitrogen cooling. > I am also considering construction of a thermoelectric cloud chamber for > charged particle evaluation of the LENR powder ash (a la Piantelli). > That would be pretty cool. On occasion I've looked for the Piantelli anecdote, which I read somewhere, but I haven't succeeded yet in tracking it down. Eric
