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 Also if they had put a probe into this stream of steam and water and withdrawn it, it would have come out wet, whereas in previous tests it was dry.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.

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.

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
That is a more readable post than Kevmo’s post 39.
