Observation of excess heat by activated metal and deuterium gas
Reports of heat-generating cold fusion reactions in the nickel–hydrogen system have been increasing. The reactions mainly involve nickel with other additive elements. The authors of these reports emphasized the importance of an extremely clean system in the electrolytic tests in which excess heat was generated. Therefore, we attempted to detect excess heat after reducing impurities to a minimum by cleaning the electrode carefully and then fabricating nanoparticles in situ in our test system, without ever exposing them to air. As a result, energy far exceeding input was continuously obtained. In the best results obtained thus far, the output thermal energy is double the input electrical energy, amounting to several hundred watts. The generated thermal energy follows an exponential temperature function. When the reactor temperature is 300°C, the generated energy is 1 kW. An increase of the temperature is expected to greatly increase the output energy.
We have recently improved the preparation of the electrode material. This enhanced reproducibility and increased excess heat. The new methods are described in an appendix.
New Mizuno glow discharge paper
- Active electrode is tin amount of palladium deposited on nickel mesh – by simple RUBBING
- Nickel mesh does not work alone
See appendix A on page 26. These details are easy to overlook.
Speculation – Given that palladium works far better in electrolysis when alloyed with silver and given that nickel in this case only works with a thin coating of palladium, then an area of improvement (for the fine results already presented in the several hundred watt range) would be to coat the nickel mesh with both silver and palladium or do the rubbing with the alloy – not the pure Pd.
E-cat world published a quick summary to discuss on that paper
To be confirmed but it seems a breakthrough.
I noticed that Mizuno explained that the deposition of Pd on Ni electrode through plasma process, prepare the reaction.
It remind me the Cathodic Sputtering that Didier grass&al realized on their electrodes, leading after an electrolysisi to a brutal excess heat production possibly of LENR source.
The Ni mesh around the inner surface of the reactor is discharged by high voltage of DC current
between the wire around the heater electrode and another Pd wire electrode. The reaction gas is
99.9% pure deuterium (Nippon Oxygen).
This state is continued for about 10 to 20 hours, and Pd is deposited on the nickel surface.
Doing this produces the conditions needed to generate excess heat.
...SEM observation of nickel surfaces before and after treatment are shown in Fig. 31 and Fig. 32. The surface roughness after processing is remarkable, and its size is not uniform. The particle size was distributed in the range of several tens to 0.001 micrometer.
The distribution of Pd on the nickel surface after treatment is shown in Fig. 33. In this photograph, it is indicated by purple dots. It is almost uniformly distributed. With unprocessed nickel, it is impossible to generate excess heat at all. However, if the surface is covered with particles and further Pd is present on the surface, excess heat is easily generated. The smaller the particles are, and the more Pd is uniformly present, the more the excess heat is generated.
The paper is very detailed on the process, and may help replicators (even if I imagine getting help from Mizuno to replicate will be essential).
