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.

A heat-flow calorimeter was introduced into the D/Pd gas-loading system to confirm the reliability and accuracy of the results obtained by isothermal calorimetry in the previous work. The effects of input power (electrical current) and pressure on excess heat were discussed under different experimental conditions. The results showed that the heat-flow calorimetry had higher accuracy than isothermal calorimetry. Under deuterium pressure of 30 kPa, the excess heat power decreased with the decrease of the input power, and the maximum excess heat power was (6.40 ± 0.19) W with an input power of 380 W. In the experiments of discussing the relationship between pressure and excess heat, the results showed there was a maximum excess power of (10.28 ± 3.40) W when the deuterium pressure was 220 Pa. The excess heat measured in the system was far more than that in chemical reaction. The results of SEM and EDS implied that excess heat came from nuclear transmutation processes.

Excess Power

Previously on the work [1-3] of excess heat triggering in a D/Pd gas-loading calorimeter system, we got that the system had the maximum excess power (6.398 ± 0.191 W) at the condition of an optimum current (8.47 A) and a deuterium pressure (3 × 104 Pa). In order to get higher excess heat power and to confirm the reliability and accuracy of the excess heat triggered by current in the previous work, we did a serials of experiments under different conditions. The results came from the heat-flow calorimeter system showed that the system produced the maximum excess heat power (10.284 ± 3.402 W) when the D2 pressure was 220 Pa. The key conditions of generating excess heat need to be further studied.

In this paper the reaction heat development of alkali activated aluminosilicates is studied by an isothermal heat flow calorimeter. The highest reaction activity is observed during two hours after mixing. The hydration heat power at early time is influenced mainly by the composition of tested mixtures involving ceramic dust as precursor and different amounts of sodium hydroxide and water glass as activators and by temperature.
