1) Introduction
About three years ago I was deeply involved in replicatios of Mizuno-type of excess-heat experiments (high voltage electrolysis). Several units on my CF website (see point 2f below) are based on this research. My involvment ended about two years ago, when I became one of participants of The Galileo Project (replications on SPAWAR-type experiments) organized by Steve Krivit. 

But Pierre Clauzon, and his French colleagues, continued exploring the excess heat claim made by Mizuno and his coworkers. The purpose of this unit is to summarize recent results of French researchers, and to append descriptions of their future results, when they become available. 

2) Current Status 
a) During a private conversation in New York City, Pierre Clauzon updated me on his high voltage electrolysis research and mentioned additional experiments he hopes to conduct in the future. About one year ago we met in Pierre’s laboratory in Paris. We performed the experiment together (using the old watt-meter) and the COP was again significantly larger than 1.0, for example 1.3 at 350 volts. The difference between 1.3 and 1.0 is statistically significant, considering reproducibility of the results. 

b) New results, similar to those reported at ICCF12, were reported by Pierre in Sochi. But the claim of significant excess heat, reported in Yokohama and Sochi, is now withdrawn because an important systematic error was discovered. Pierre told me that measurements of the input energy were incorrect. The instrumental systematic error was due to unsuspected limitations of the Unigor-390 watt-meter. That instrument is reliable up to frequencies of 0.1 MHz while current fluctuations apparently contained much higher frequencies.

c) In new experiments, this instrument was replaced by D6000 Norma Goerz wattmeter; it is said to be reliable up to the frequency of 2 MHz.  New experiments were performed by using a “boiling water calorimeter.” The principle of measuring heat energy is the same as before (from the amount of steam produced during electrolysis) but the cell is surrounded by boiling water, rather than by air. The size of the cell, in these experiments was 1 liter. In these experiments excess heat was insignificant at all voltages, between 150 V and 350 V. 

d) But that was not the end of the story. In the most recent high voltage electrolysis experiment, however, a significant excess heat was again discovered. The D6000 watt-meter was used in the latest experiments. The COP (coefficients of productivity) at 250 V were 1.09, 1.00, 1.10 and 0.97. At 300 volts, the COP values were 1.06, 1.08, 1.04 and 1.01. These results are very preliminary.  They were obtained in an electrolytic cell (actually a dewar) whose volume was 5 liters. Pierre thinks that mechanical perturbation of plasma, in his small cell, were interfering with generation of excess heat. 

e) In other words, the tentative “no excess heat” conclusion (see point 2c above) remains uncertain. Hopefully, the situation will become clear next month (after another sequence of experiments with the large dewar cell).
