Excess Heat Power Measurement by Heat-Flow Calorimeter in a D/Pd Gas-Loading System

Abstract:

In order to confirm the reliability and accuracy of the excess heat triggered by current in the previous work [1-3], a new designed and built heat-flow calorimeter [4] was introduced in the same D/Pd gas-loading system as mentioned previously. The calorimeter was calibrated in nitrogen atmosphere and the results between the input power (P) and the exothermal electromotive force (V) could be simulated by a quadratic equation: P = (15.356 ± 0.068) V – (0.014 ± 0.039) V². The maximum excess power (6.398 ± 0.191 W) were found at the condition of an optimum current (8.47 A) and a deuterium pressure (3 × 10⁴ Pa). The reproducibility was 3/3 and the total excess energy released in these experiments was about 0.70 ± 0.02 MJ within 40 hours, which means (1.6 ± 0.1) ×10³ eV for each palladium atom. The excess heat power and excess heat energy were far more than that in a chemical reaction.
