Hello Mary, I wonder if you could ask your source to explain the bump in the curve that occurs at 16:00 on the second chart? It looks like this is not demonstrated in any of his curves. The bump is in the temperature of the ECAT water bath T2 and is very distinct. Dave

The informant now provided computations of the power and energy vs time curves for the model, assuming only electrical (Joule) heating (no LENR reaction) as you can see here: http://i.imgur.com/SWbvW.jpg Once again, the original diagram of the model and temperature vs time curves are here: http://i.imgur.com/XAdrr.jpg My contact says: "Of course the model is an approximation of reality and many details of the ecat are unknown, for instance I assumed there were lower fins (I saw it here http://www.mail-archive.com/[email protected]/msg52853.html ) but I am not sure it was right. Anyway, the model shows that a few dozen kilograms of iron, well placed around the electric heater, (no hidden source is needed) would be able to keep the water boiling for nearly 4 hours. See the temperature vs time curves for points R, A, and B. They remain above the boiling point well after the "reactor" shutdown. This confirms that Lewan was right when he reported feeling the boiling after the shutdown. Lewan also said that he measured an external temperature ranging from 65 to 80°C. This is compatible with the model's temperature/time curve for point "C" (T sub C on the plot). But the best confirmation of the validity of the model is the trend of the temperatures after the shutdown -- the curve from the model for point T2 follows the measured plot from the experiment reasonably closely. I think that Lewan is honest about what he personally sees and measures but he may be wrong some of the time when he bases his conclusions on data reported by others." Once again: this is *not* my work. I am simply passing it on. If you have any questions, I'll be happy to forward them to my source person and relay the answers back.
