The reason that I included the pressure regulator in the diagram of the output of the E-cat was based on two pieces of evidence. First, the temperature, T2, in the 10/6 test gets too hot for room temperature boiling water, but is about right for water at 1 bar (gauge). Second, if you look at the video of the test of the same E-cat design on September 7, (http://translate.google.com/translate?hl=en&rurl=translate.google.com&sl=it&tl=en&u=http://www.nyteknik.se/nyheter/energi_miljo/energi/article3264362.ece) at about 6:40 into the video the water inlet valve is opened with no hose attached, to drain the hot E-cat into a large plastic container. What comes out is water at high pressure and it is flashing to steam (there should be no steam if it is at atmospheric pressure because it is coming from the bottom of the reactor). This suggests that the water really was above 100C inside the E-cat (not just an artifact of T2 probe placement near or touching the reactor body) and of pressure above 1 bar absolute. The ejected water pressure is consistent with about 2 bar absolute (1 bar gauge). Also, the length of time the water comes out at the high pressure is further indication of water flashing to steam as the pressure is released. Bob Higgins ________________________________

Do you think it unlikely that the secondary outlet thermocouple error changed with the rate of steam flow through the primary given it's poor placement? -Have you used any of the videos to estimate primary water flow rate, or check for variation? The noisy pump delivers maximum of 2ml/stroke, and I believe this drops at higher pressure (pump rated for max 1.5bar). -How do you explain the temperature variation in the reactor once it gets above 100°C, and in particular the fact that highest temp doesn't correlate with greatest power? Do you think the steam is being superheated? Normally when a fluid's temp is raised above ambient pressure it will rapidly boils off to drop it's temperature to ambient again, do you think there was some sort of variable flow restriction in the outlet from the reactor to prevent this?

With this information it is possible to estimate the water mass in grams remaining within the ECAT as it responds to water pump input flow and vapor escape. There are two adjustable variables: Correction Factor for the thermocouple error in the secondary; and, water flow rate into the ECAT in grams per second. There are two types of charts to view. One shows the water remaining within the ECAT in grams as a function of time. The second displays the total vapor flow out of the ECAT at any chosen time. The information contained demonstrates that the ECAT should not overflow under normal operational conditions. Of course this is based upon assumptions which may need adjustments. This is my first post to the vortex and I have my fingers crossed. Dave
