Progress towards Understanding Anomalous Heat Effect in Metal Deuterides

The present article summarizes anomalous heat events which were observed in a large number of electrolysis experiments using heavy water and palladium-based cathodes. The amount of excess heat produced by some of these experiments is too large to be accounted for by any known chemical processes. It was found that events of the anomalous heat effect (AHE) are accompanied by increased cell voltage during electrolysis and that there are characteristic cathode surface morphologies which are associated with excess heat events. AHE has been observed during electrolysis following dynamic stimulation of the cell by time-dependent electrolytic currents (SuperWaves) and ultrasonic excitation. Past experiments have increased our understanding of the anomalous heat effect in the palladium-deuterium systems, but there is much left to be learned.
