North-Holland PHYSICS LETTERS A Calorimetry of the Pd-D20 system: from simplicity via complications to simplicity

We present here one aspect of our recent research on the calorimetry of the Pd-D20 system which has been concerned with high rates of specific excess enthalpy generation (> 1 kW cme3) at temperatures close to (or at) the boiling point of the electrolyte solution. This has led to a particularly simple method of deriving the rate of excess enthalpy production based on measuring the times required to boil the cells to dryness, this process being followed by using time-lapse video recordings. Our use of this simple method as well as our investigations of the results of other research groups prompts us to present also other simple methods of data analysis which we have used in the preliminary evaluations of these systems. 1
