You're understanding of thermal inertia is incorrect. We don't expect a rapid decline. With Megajoules in storage a 1000W draw will change the temperature but little. Its like your telling me you can slow down a Mack tuck by shooting peas at it. It'll decelerate quickly at first but as it comes to a halt it will be more difficult to slow it dowm. Even a cursory glance at the data will show that enormous energy is being pumped into the E-Cat with very little coming out. In 10 Minutes about 1.5MJ goes in at full power. Nothing comes out until overflow at 20:16. At 20:50 there's 3.7 g overflow at 90C. That's about 1`/3 of what's going in.From 19:00 to 19:40, i.e 40 minutes, the power is increasd from 1/2 to full. I'll count that as 20 min. at full which is 3MJ. From 19:40 to 22:40, 3 hrs @ full gives 27MJ for a total of 30MJ. There would appear to be from 17 to 20L of water stored in the E-Cat. It takes ~5MJ to heat 17L of water from 30C to 100C. So it would appear that there are 25MJ stored elsewhere at this point. That's enough to produce 1000W for over 7 hrs. And there is probably additional heating. ----- Original Message ----- From: Jed Rothwell To: [email protected] Sent: Thursday, September 15, 2011 10:49 AM Subject: Re: [Vo]:The September E-Cat

The hose was taken off. Water pulsed out of the outlet right at the exit of the E-cat in large quantity. It obviously did not condense there. That is true. However, in the Krivit test and other previous tests, the flow rate was lower, so I do not think you can compare them. Also if they had put a probe into this stream of steam and water and withdrawn it, it would have come out wet, whereas in previous tests it was dry. In general I agree that a non-steady state mixture of water and steam is difficult to measure. I wish that Lewan had sparged the steam and water. Before this test, I sent messages to Lewan, Rossi and others urging them to do this, but they did not. They had a perfect opportunity to do this, with that large plastic trashcan. It will easily hold enough water to condense all of the steam. By the way, flow rate was almost exactly 3 g per second. Input power will be enough to vaporize 0.7 g assuming no heat radiated from the device. That is extremely unrealistic. So the fact that about half the water was vaporized does indicate there was excess heat. More to the point, during the 35 min. heat after death event, the temperature did not decline much. This is proof that there was anomalous heat. Stored heat can only produce a temperature that declines rapidly at first and then gradually. After the power went off the temperature did not decline rapidly. Therefore the input power of 2.5 kW was only a fraction of the total power. If the total power was around 5 kW where 2.5 kW was half, the temperature would've fallen a lot faster and sooner. Lewan estimates the water volume of the cell at 22 to 30 L. If there had been no anomalous heat the temperature would have fallen sharply within minutes. You can boil a pot of 22 L of hot water and observe this easily. Turn off the heat, and it stops boiling instantly. It starts to cool a few degrees in minutes. The temperature never rises and never stabilizes, unless you change the insulation (or the flow rate, in this case). In this case the temperature will certainly fall quickly because during the 35 min. 6 kg of cold water was added to the cell. The heat capacity of this water far exceeds the total heat capacity of all the metal in the cell. Now the new E-cat never reaches equilibrium. This is a far more difficult regime in which to do accurate calorimetry, and a far better regime for self deception. That is true, but there is no doubt it was boiling for 35 minutes with no input power. Anyone who ignores this fact is engaged in the worst kind of self-deception imaginable. Further, the E-cat mass has been greatly increased, and the max input power increased. The "heat after death" from mundane causes will now obviously be much longer. This cannot sustain boiling for more than a few seconds, at this flow rate. Metal cannot store much heat, and this cell was producing excess heat the whole time, so there was no possible storage at all. With 2.5 kW input only, it would have transitioned from boiling about one third of the water to boiling none of it, and that would have taken a few seconds at most. - Jed
