Coolescence's analysis of Dr. Mel Miles 2016 Ridgecrest experiment
Summary of the Experiment and Analysis
In July 2016 Dr. Melvin Miles performed a 13 day experiment at his home in Ridgecrest, CA where he charged a Pd cathode in a heavy water electrolyte containing 0.1 M KNO3 . The experiment produced a claimed excess heat starting almost immediately and peaking over 70 mW. Details of this experiment were presented at ICCF-20 and a satellite meeting SSICCF20. Some details of the Ridgecrest experiment are contained in Miles' presentation "The Fleischmann-Pons Calorimetric Method And Equations”
Dr. Miles generously provided Coolescence with copies of his lab notebook, pages 85-94, which contained measurement values that were transcribed into an Excel spreadsheet at Coolescence. At Miles’ suggesting with the help of LENR-CANR.org the spreadsheet is now publically available here.
For his experiment Dr. Miles used custom-built isoperibolic calorimeter. Like all calorimeters of this type the difference in temperature between the inside and a stable outside is used to infer heat produced. The amount of heat reported by the calorimeter depends linearly on a calibrtion coefficient k. We suggest charactersitics of the calorimeter design may allow for unanticipated variations in k. As a result the uncertainity in the calorimetric measurements may be as much as several percent. We argue a more likely interpretation for the data set is no excess heat and a larger than claimed calorimetric uncertainty.
