To my knowledge no testing for transmutation or occasional high energy radiation has been made. Could you tell sources for this? Please. I did a quick experiment today at work. I used an old NiMH AA cell that was not been charged for some years. It was completely empty. I applied a reverse DC current of 3 Ampere for one minute or so. The voltage at the cell was 3V. This are 9 Watts, but the cell remained cold and the voltage did not change. With 9 Watts it must become warm! So I have now discovered anamolous lack of thermal energy. ;-) I was unable to make a longer experiment, because I dont want an exploding AA cell at work. I intend to make a secure (remote) setup and to do this at home. I found this document, where NASA found excess heat in H-Ni electrolysis. http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19960016952_1996035672.pdf They did, however use platinum as an anode and nickel as a kathode. Also they did not use KOH but K2CO3. They report 1.68 as COP. I ask myself, if this is repeatable, why dont they do their research with this setup and try to improve this? Could it be this document is an april joke that was leaked out? I cannot afford platinum, I hope graphite can also be used instead as a chemical inert electrode. Best regards, Peter.

It might be a rewarding source to find other new stuff, because Italia is very active in LENR research. BTW, when I wrote in my previous posting, I found an anormal lack of thermal energy while applying a reverse current to a NiMH cell, I did not mean this as a joke. It sounds funny, but it is serious. A 10W resistor will become warm after some seconds under full load. The NiMH AA cell, which has similar size did not become warm at 9 Watt for 1 minute. Because energy cannot vanish, this means, there is something (chemical?) going on inside. The energy was stored inside instead being converted to heat. This is absolutely sure. Best, Peter

H2 and O2 bubbles .15 micrometer burn, damaging electrodes in AC electrolysis -- could complicate cold fusion devices: Rich Murray 2011.09.28 [ Rough surfaces on electrodes and other components, with catalytic impurity concentrations and higher localized voltages and temperatures, may cause larger microbubbles to spontaneously combust, increasing surface damage and adding complex reaction products to the electrolyte, producing local heat and more catalytic deposits -- making a bubbling scientific witch's stew... ] http://www.physorg.com/news/2011-09-spontaneous-combustion-nanobubbles.html Spontaneous combustion in nanobubbles September 28, 2011 Enlarge [ black and white images ] Formation of bubbles at the electrodes during electrolysis (can be seen in a and b). Situations c, d, and e show the formation of both hydrogen and oxygen on the left, hydrogen alone in the middle and oxygen alone on the right. Situation e shows combustion taking place on the left. No bubbles can be seen on the electrodes. (PhysOrg.com) -- Nanometer-sized bubbles containing the gases hydrogen and oxygen can apparently combust spontaneously, although nothing happens in larger bubbles. For the first time, researchers at the University of Twente’s MESA+ Institute for Nanotechnology have demonstrated this spontaneous combustion in a publication in Physical Review E. They intend to use the phenomenon to construct a compact ultrasonic loudspeaker. The fact that a violent reaction takes place is already evident from the damage incurred by the electrodes with which the reaction is initiated. These electrodes are used to make hydrogen and oxygen by electrolysis, in the usual manner, in an ultra-small reaction chamber. If the plus and minus poles are continually alternated, tiny bubbles containing both gases arise. The frequency with which the poles are alternated determines the size of the bubbles: the higher the frequency, the smaller the bubbles. Combustion only takes place in bubbles that are smaller than 150 nanometres (a nanometre is a millionth of a millimetre); nothing happens in larger bubbles. Early experiments in microreactors also showed that nothing happened in larger bubbles; the heat can dissipate to the larger internal surface. Meters per second Researcher Vitaly Svetovoy was working on the construction of an actuator for rapidly building pressure when he came across this phenomenon. Such actuators are, for example, used in loudspeakers for ultrasonic frequencies undetectable by the human ear in the medical world. None of the mechanical techniques currently available are suitable for making a very compact loudspeaker of this kind and still achieving a 'deflection' of metres per second on this scale. Svetovoy thought, however, that it might be possible by building up pressure with bubbles. The problem was that the bubbles could be made very rapidly but that they did not disappear quickly enough. The combustion reaction that has now been demonstrated might solve this problem. But it causes other problems too, such as the damage to the electrodes. That is what we now have to look at, Svetovoy said. This research was carried out by Prof. Miko Elwenspoek's Transducer Science and Technology group of the University of Twente's MESA+ Institute for Nanotechnology. The article 'Combustion of hydrogen-oxygen mixture in electrochemically generated nanobubbles' by Vitaly Svetovoy, Remko Sanders, Theo Lammerink and Miko Elwenspoek appeared in Physical Review E on 23 September 2011.
