Cavitation-induced excess heat in deuterated metals. Final report

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 4He 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
