Introduction: "Experiments on cold nuclear fusion and LENR"
First, note that the tested voltage range starts at 10V and ends at 30V with 2.5V steps. This allows for a broader and more detailed overview of the behavior of the reaction cell. In March 2021 measurements had started at 15V and ended at 30V with jumps of 5V.
Comparing the results of April 2021 with those of March 2021 it is evident that the change of material has led to a significant increase in the final COP:
at 15V it is 0.660 against 0.621 +6.3%;
at 20V it is 0.703 against 0.637 +10.4%;
at 25V it is 0.712 against 0.629 +13.2%;
at 30V it is 0.673 against 0.606 +11.1%.
This data taken alone would tend to confirm the hypothesis of the presence of a weak thermal anomaly. However, it must be considered that the electrical power input has also increased and this cannot be neglected:
at 15V it is 77.5W against 53.6W +44.6%;
at 20V it is 145.3W against 93.5W +55.4%;
at 25V it is 176.8W against 129.5W +36.5%;
at 30V it is 210.0W against 159.0W +32.1%.
The increase in the electrical power input could have led to an improvement in the efficiency with which the energy is transferred to the material, thus making it possible to recover a greater share of heat.
Another noteworthy comparison is between measurements of the final COP with the same voltage:
at 20.0V it went from 0.703 to 0.721 to 0.717 to 0.711;
at 22.5V it went from 0.708 to 0.716 to 0.718;
at 25.0V it went from 0.712 to 0.706 to 0.711;
at 30.0V it went from 0.673 to 0.678.
The first measure of the COP is generally lower than the following ones. This means that over time and as the number of hours of stimulation increases, the material responds differently to stimulation. There is currently no evidence to indicate what kind of change has occurred. A hypothesis is that the different response to stimulation is due to the accumulation of hydrogen in the material.
