**An interesting abstract from the 16th meeting of the Japan Cold fusion Group earlier this year. If anyone (Jed?) has access to the complete paper I - and others I am sure- would be very interested to read it.**

**Thermophysical analysis of anomalous heat generation (AHG) reaction between metal and hydrogen Tadahiko Mizuno (HEAD Co.) Hideki Yoshino (C. P. Company LTD.)**

We have developed a strict method of measurement and analysis to confirm AHG between hydrogen and metal. The factors involved in the energy analysis are electricity, mass (heat capacity), thermal conductivity, mechanical and thermal radiation. These contribute the most to heat analysis and can be easily estimated using matrix equations to calculate unknown quantities. We describe the results of the AHG experiment and the methods of thermal calibration within the framework of our chosen measurement system. To confirm AHG, we elected four factors that contribute to positive heat values: input power, ambient temperature, temperature of the reaction system, and pump temperature. For simplicity, we neglected heat losses from radiation or evaporation of the recirculating water. We estimated that an even larger heat generation would result from incorporating these heat losses into the calculation.

The observed value of ratio of heat out and input (Hout/Hin) was less than unity for the plasma discharge test. The value of excess heat could be estimated from the input energy that was consumed by the chemical reaction during the plasma discharge. We can compare the AHG test with the calibration and to obtain the mathematically proven that abnormal heat was produced because the correlation coefficient R of the calibration data was very high as 0.9996. We limit out focus to the range of input was from 40 to 50 W; there are 10 calibration data sets and 20 AHG data sets in this range. We use Welch’s t-test to compare the average value of the Hout/Hin for the experimental tests with the calibrations to determine whether there is a statistically significant difference between the two results. Null hypothesis: H0, the average value of Hout/Hin is equal for the test and control data sets.

Alternative hypothesis: H1, the average value of Hout/Hin for the test data set than is larger than that for the control data set. From the significant difference test results, when it is the critical region 1%, the P-value (one side) is many orders of magnitude smaller than 0.01, and the t-value is much larger (10.81) than the t-boundary value. Further, we reject the null hypothesis; the average value of the test data is greater than the calibration data with 99% accuracy. We confirmed the occurrence of AHG through experiments and mathematical analysis. We measured excess heat was 10 W at input was 40 W; we estimated that the specific AHG was 0.3 W/g (on the basis of the mass of the Ni reacting material) and 30 mW/cm (on the basis of the surface area of Ni). This excess heat generation was calculated by a rigorous thermal analysis. Until now, AHG was confirmed due to its low experimental reproducibility and disagreement with theory; however, this study definitively confirmed AHG. This finding is a significant advancement with important ramifications. Further research is needed to elucidate the theory and mechanisms underlying this phenomenon. Varying different parameters, such as the reactant gas, we will be able to develop methods for controlling the process and harnessing the phenomenon for practical applications. We plan to conduct even stricter thermal analyses in the future and to broaden the scope of parameters evaluated.
