The guys on Vortex-L discuss this fact that self-sustain mode only needs a few minutes to surpass chemical capability at times.

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 Also if they had put a probe into this stream of steam and water and withdrawn it, it would have come out wet, whereas in previous tests it was dry.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

Sorry your skills don't include making a block of text readable.

Rothwell has consistently refused to consider the reasonable "models" for Rossi's E-Cat, and only chosen to try to know down his straw-man versions.

In this example, he refuses to even consider that there might be something inside the "secret" 30-litre, 80KB box that Rossi won't let anyone examine. His argument that a pot of water stops boiling as soon as you turn off the heat ignores the fact that a pot of water with a large iron block, heated to 500C, will continue to boil for a long time after the heat is turned off.

He also likes to use the analogy of dumping a heated iron block in a barrel of water to show that it would cool down quickly. That's his straw-man version. In Rossi's actual demos, there is a very small trickle of water being fed into the E-Cat, nothing at all like a "barrelfull"

Rothwell has devoted his life to proving that cold fusion is real, so it's no wonder that he's arguing so hard for it. Without it, his life's work is a waste.

But his arguments don't stand up to scrutiny, as many of the other Vortex posters have amply demonstrated.

For paragraphs, use [p] but replace my brackets with the arrows over the command and period. That would make it much easier to read.
