This is irrelevant difference. Water flow is there only to ensure that water level does not drop below reactor core, so that core does not expose to air. Water is not there to demonstrate how much E-Cat produces energy, but it's main function is to control reactor temperature and prevent reactor meltdown. This is the very essence of boiling water reactors. See, the purpose water for measurements is irrelevant component, but it is used, because water is very convenient substance as boiling water reactor coolant. That is because the enthalpy of water phase change is so high. This enables to divert much of the heat energy away from reactor core while the temperature of coolant remains constant. This is very crusial, because according to sig. Rossi, his E-Cat is very sensitive for internal temperature of reactor. > The problem with this is that dry steam above boiling would require a > chamber hotter than boiling, this can't happen unless the chamber > substantially empties. It is perfectly possible that pressure rises inside E-Cat so that boiling point is at 100.5°C or 0.8°C higher. But what is impossible without very special setup, is that reactor produces wet steam and such a high pressure simultaneously, that it could cause boiling point to rise. If steam is very wet, then the energy output of the reactor is very low. And it cannot heat up reactor that much that it will cause significant pressure build up. Pressure build up depends on that there is significant amount of dry steam present! But, it is possible that if heating element is very hot, steam temperature can rise somewhat over boiling, because surface tension of water enable the bubble formation. And this gives some time for heating element to heat steam directly in gaseous phase although heating element is under water. Therefore it should not be impossible, that steam temperature finds its equilibrium that is 0.1-2.0 °C higher than actual boiling point. This depends on what is the temperature difference between heating element and boiling water. > A teapot with a fixed flow input could overflow, indeed, if that's the only > way > that water is added, we can predict that, unless there is some complex > feedback mechanism either on flow or on heat vs water level, the water will > either boil away and the chimney temperature will increase, or water will > start to overflow, some portion of the water will flow out. You do not have any evidence for that E-Cat can overflow, therefore this is just empty speculation. If you could even speculate with this possibility seriously, you should know what is the inner volume of the E-Cat. But you do not know even such a rudimentary detail about the E-Cat. This kind of speculation is useless and nonproductive, because first of all, temperature reading would be below 99.7°C, because there cannot be pressure build up without intensive production of dry steam. But as I stated this problem is easy to "fix", that you just introduce a secret heating element near thermometer that feeds false temperature readings. On the other hand, if E-Cat is a hoax, it far more easy to construct such a way that Rossi just hides a internal hydrogen tank. E.g. I have suggested that the stand where E-Cats are mounted could be hollow hand that would be easy way to hide a hydrogen bottle. Therefore Kullander's and Essén's observations about the E-Cat has exactly zero scientific value, because they cannot tell a part, whether they witnessed a catalyzed hydrogen burning or catalyzed cold fusion. –Jouni
