That means a small droplets can be entrained in the steam and would not be trapped by a simple tee. And if one accepted a partly filled ecat at the beginning to explain the first 5 minutes before boiling (assuming the valve started out open), then by the time the ecat is filled, there will be plenty of steam available to entrain the water as it is forced out. Moreover, the valve could have been closed before the ecats filled up. According to Lewan's video, it is closed at 3:00. > I do not think it is fair to say he is lying about his measurements as > some suggest. > You are suggesting he is lying about the constant output flow rate. He is saying they collected 5 liters, but the statement that they collected *all* the water is clearly unsupportable. Even if the phases were completely separate, some water would surely get past the trap. And if it's a mist, nearly all of it would. This device allows him to claim ignorance, so it is not necessarily a lie to say it collected all the liquid; it is merely not plausible. The closed valve, on the other hand, looks like deliberate deception. But maybe Rossi did it hoping F. would not notice. > Also, an explanation for the large, fast rising temperature pulse after > the shoulder can not be explained by the constant water theroy.

And it fits with the claims of Rossi and F. of constant flow rate.

For example, if it were 90 % full, then the power would have to reach 470 kW in about a half an hour. Still not plausible, given the time it took to warm up to 70 kW. > No one needs to be a liar and the readings do not need to be fudged. > The claims of Rossi that the output flow rate is constant and the output power is constant would be lies. And the accurate flow rate selection to maintain the level just below full needs to be assumed. No fudging at all is needed for the constant flow rate model. > Why should we not use logic to arrive at the correct answer if it fits? > The problem is you need something more than a fit, if there are other possibilities that also fit. The goal here is not to find a way to make Rossi's claims consistent, but to make his claims the only ones that can explain the observations. Otherwise it's not proof. Not only is cold fusion not necessary to explain the (reported) observations, but if you look at it without your foregone conclusion stuck in your mind, they are not needed for the simplest and most likely description.
