Intense cavitation at a palladium interface with heavy water apparently generated excess heat. The heat appears to be far too large to be a chemical of metallurgical transformation. By inference, a nuclear reaction is the likely heat source because helium of a unique isotopic character has frequently been observed in the gas phase. This report summarizes selected examples of energy output, including excess energy and measurement of {sup 4}He via mass spectrometry. Overall, this work confirms the claims of Fleischmann, Pons, and Hawkins concerning the production of excess heat in D-loaded Pd. The success rates (about two-thirds of the 65 tests performed showed excess heat) appears to be greater using the ultrasonic cavitation technique than relying on the cathodes of electrochemical cells.
