Hot Cat Replication Attempt: Update – Experiment Completed
|January 13, 2015||Posted by Jack Cole under Andrea Rossi, E-Cat, Hobbyist LENR|
For a couple of months, I have been working on various combinations of reactor cells and materials in an attempt to replicate some of the concepts of Andrea Rossi’s Energy Catalyzer. There have been several failed experiments and several promising experiments. The most recent experiment was the most promising finding yet–yielding an apparent excess heating of 10.4 watts. I utilized a different design in this experiment of sealing the heating element inside of the reaction chamber with the fuel. Using this approach, I was able to use DC current with a programmable power supply to reach higher temperatures within the core of the chamber. The temperatures were recorded via a PC connected to a type K thermocouple attached to the exterior of the alumina tube. Note that the internal temperature is much hotter as demonstrated by incandescence when the external temperature was 350C (suggesting internal temperatures > 550C). This study used a different method of producing hydrogen within the cell than the LiAlH4 that is safer to handle while loading the fuel.
I am not making any bold scientific claims with this experiment. More work needs to be done to confirm/dis-confirm these findings. This experiment falls into the category of “promising” pending further study. This post may be updated as I explore the data further. Additionally, the experiment will continue to run for a longer period of time to see if the excess power goes to zero. It is currently at 5.5 watts excess after 12 hours of demonstrating apparent excess heat. It has slowly been decreasing.
After running another 13 hours, the resistance wire must have broken within the cell (likely related to thermal stress and/or hydrogen embrittlement). The elevated temperature remained, but it was significantly less than where it reached during the heat up phase.
As you can tell from the chart, the apparent excess heating was slowly dropping over time. This tends to bolster the validity of the calibration run and the hypothesis of the existence of excess heating. It is unfortunate that the heating element wire broke since it would have been interesting to see if it eventually would have returned to the calibration level values. For reference to the above chart, see the measured input power levels below.
Because of the power data fluctuations, I thought it might be of interest to chart the resistance of the heater coil. It is interesting how little the control run varies versus the experimental run.
