Replication of Ni/LiOH Excess Heat Results: Updated – Experiment Completed

After the earlier success of producing apparent excess heating with a blend of nickel powder, lithium hydroxide, aluminum powder, and iron oxide (Fe2O3), there followed three failed attempts to repeat the results. The present experiment appears to have been successful. The fuel was modified in this experiment thanks to fellow Vortex member Jones Beene who sent a special ceramic powder mix based on lime. It was believed that the special luminescence properties of lime may enhance the effect. The fuel was composed primarily of the lime-based powder by volume. Another difference with the present experiment is that the entire tube was filled with the fuel. The actual nickel weight is significantly less than used in the Lugano test, but I don’t have precise measurements on the amount.
The current experiment utilized a second set of temperature sensors (one for measuring ambient temperature, and the other attached to the top of the tube furnace). This allows the tube furnace to act as a simple calorimeter and removes the need for a control run to be performed with every experiment.
The experiment generated a maximum of 10.6 watts of excess heating over 90 watts input (11.8% gain). Of note was that the excess heating was much more persistent.
Note that the excess heating does not occur until the 90W step.Because the excess heating was of long duration, and showed no signs of stopping, some steps were taken to attempt to quench the reaction (assuming that is the cause). The tube furnace was opened and the cell photographed. The resulting temperature drop was quickly reversed. The next attempt to quench the reaction was performed by stepping the power down by 20W per step. Each step was allowed to run for approximately 4 hours for the temperature to settle. There appeared to be excess heat at every step until 10W was reached. At the 10W level there was no indication of excess heating. When the power input was again increased to 50W, the apparent excess heating returned.
Two out of five experiments demonstrated apparent excess heating with a maximum of ~10W. Assuming there is no systematic factor that has been missed in these experiments, it may indicate LiOH and aluminum powder as viable alternatives to the more dangerous LAH used in the Rossi and Parkhomov formulations.
The experiment continues to run, and updates will be reported here.
After attempting a higher power input (130W) the resistance wire broke ending the experiment. Here is a chart of the calculated excess running over the 90W step lasting 19 hours and 24 minutes.
Additionally, here is a chart showing calculated excess power at each step in the experiment.
The results of this experiment are not definitive, but do show enough promise to warrant further investigation. The next steps will be working towards increasing the COP and improving calorimetry.
