Your description is wrong, because percolator effect does not produce wet steam, but hot water and little dry steam (steam quality ca. 98%). What you are here saying that coffee maker produces ultra wet steam instead of hot water, what is as a concept silly. Using such a silly concepts like "wet steam" in context where they do not belong gives quite clear message that you are not familiar with the field you are trying to analyze. It is not good sign that you give own definitions for the physical concepts. (I know this, because I have done this also some times) But instead of calling percolator effect, you should calculate what portion of inlet water is evaporated. It is quite clear that the whole E-Cat is quite quickly emptied from water due to percolator effect. > The measurements required for even an amateur level of calorimetry were not > taken.

This is more than enough to estimate quite accurately the total enthalpy. If your data is flawed in many ways, then you need to be creative and try to reconstruct as much as you can. As I showed quite clearly, that there are several methods to try to calculate the total enthalpy. None of them is alone accurate, but together they may be significant. This is why it is useless to relay on expert knowledge, because we are in the situation that no expert knowledge is available, because situation is unique. In unique situations, we must be creative. But Horace, why do you constantly ignore the fact that steam generation in closed container is always generating excess pressure? And in this case, excess pressure was 100 kPa. Here are the three creative methods for calculating total enthalpy. And please do not just ignore them: –There was 100 kPa overpressure, and from Mats Lewan E-Cat we get one reference point (there was 32 kPa overpressure). Therfore 6-9kW is likely explanation for 100 kPa. Steam engineers could also calculate directly the amount of steam needed for generating 100 kPa excess pressure. –During the two approximately 6min power surge at 17:30 and 17:50 temperature rose approximately 1.5 times more than during the first 30 minutes when only 1.2 kW electric heater was active. Therefore total heating power when E-Cat was producing excess heat, was approximately 9kW. (This is most reliable estimation, because it calculates the enthalpy in sub-boiling temperatures. and data all necessary data is measured.) http://2.bp.blogspot.com/_852Sj2_TNC4/TTwDi8cYrtI/AAAAAAAAE1E/TT603dSfpzs/s1600/report3.jpg –And for third method, the enthalpy can be calculated using an estimation of total thermal mass of E-Cat. This is where I got that 6 kW for minimum possible power output.
