was quite well familiar with the real power of E-Cat, because water
inflow rate was adjusted in right level.
I believe he does it the other way. He leaves the water inflow rate
steady and adjusts the power output to vaporize all of the water.
In the videos you can see him adjusting the controls of the eCat,
but I have not seen him change the pump controller.
In calorimetry it is good practice to make conditions uniform and
unvarying as much as you can. Rather than changing the flow to keep
the outlet temperature stable, it is better to increase or decrease
power. Rossi has much better control over the power of his cell
than in any previous cold fusion experiment.

This conversation seems nonsensical in light of recent discussion.
Of course Rossi has "perfect control" operating in the range chosen.
All he has to do is provide enough sustained power to heat the water
flow to boiling temperature, call it Pb, or a enogh above that for a
momentary "steam" demonstration. I haven't seen any test where
thermal power reached significantly above the dryout point, call that
Pd, where all water input is converted to steam. If power had ever
reached above Pb then the steam temperature would be way above
boiling point for a sustained period. If operating above Pb then the
flue temperature will remain at or above boiling temperature, as
Cantwell demonstrated. So, Rossi is typically operating in the power
range between Pb and Pd. Pb and Pd are determined by the flow rate.
As I demonstrated earlier, if you operated in the power range Pb to
Pd then water overflow necessarily occurs. See:

Rossi says the steam is dry. All Rossi has to do to see this is
operate at equilibrium in this Pb to Pd range for a long period and
then remove the hose, or provide a transparent hose. He will then
see that water is gushing forth out the exit port. That condition I
consider to be well beyond just wet steam.
The steam can not be dry in equilibrium operation in this power
range, Pb to Pd, even if a significant amount of power comes from a
nuclear reaction. If operating in this power range water is
obviously coming out and the "calorimetry" method used is worthless.
This method is perfect for self delusion.
The dynamic situation is far more difficult to analyze because
insufficient information about the thermodynamic properties of the
device is available. Also, an effort to analyze the device dynamics
would be far more time consuming and less convincing than simply
providing good calorimetry.
Despite all this, and limited personal time, I'll continue to see I
any sense or improved intuition can be made from what we know by
using an overly simplistic black box model.
