Geezus Josh, you're grasping at straws... and obviously flawed ones at that. First: It should be COMPELETLY obvious that we're talking about the behavior/performance of the system at steady-state -- NOT start-up. Start-up is only a transient state and performance calcs are made on measurements taken during steady-state, not start-up. Yes, of course the liquid water must fill-up the entire device and flows out of the chimney during the start-up phase... Second: You wrote: "We know there are no baffles stopping liquid, because water runs through it before it is boiling." You comment here really makes me question your objectivity at least, if not your intelligence. Baffles inside the chimney would not significantly impede the water (liquid or vapor) flow up and out of the chimney! I find it hard to believe that you don't understand what baffles are... -Mark

This is certainly possible with the new, smaller e-Cats which have a much shorter chimney, but I would think that its very unlikely with the older e-Cats whose chimney looks like its at least 16 inches tall. Before the water boils, where would the liquid be going, if not ejected out of the chimney? There is a pump pushing the water into the reactor at a constant flow rate. Assuming the pressure does not increase outside the range of the pumps specs, regardless of the phase, the water will exit through the chimney. The chimney could also have some baffles inside that would prevent liquid water from being ejected; it would simple fall back down into the boiling water. Then what happens before the water boils? And where does the water fall back to, if the space is taken up by new water pumped in. If the chimney were filled with water, as some people claim, then that alone would cause a pressure increase in the ecat. The pressure increase is given by density*g*height, or 10 kPa * height (in m). So if the height of the chimney is 10 cm, then the increase in the pressure is 1 kPa, which increases the bp by 0.3C. Perhaps that's why the newer e-Cats have a shorter chimney -- because baffles were put inside. We just don't know... We know there are no baffles stopping liquid, because water runs through it before it is boiling.
