A good solution to the thermal run away problem will be difficult to achieve. It is imperative that the heat source material reach an unstable mode if controllable high gain is required. The direction of the temperature response must be reversed at the proper time in order to prevent total meltdown.
You propose a tighter connection between the heat generation mechanism and the heat extraction process which would be an excellent idea. It would not surprise me to find that Rossi eventually adjusts the coolant flow rate as part of his overall technique.

Furthermore, the heat pipe can vary heat dissipation under thermostatic control to keep the thermal stimulation of the reaction under regulated control. When heat production from the nickel powder gets too high, the heat pipe can cold it to a degree so that the powder maintains a constant temperature profile. Rossi needs to get temperature control close to the nickel powder if he wants to get the most out of his reactor.

If a spot cometo a certain upper threshold, the reactor goes out of control. The keys are uniformityof heat production inside the eCat and equal density of energy extraction alongthe entire surface. The only way to control the eCat, as far as we know now, isthrough the inside temperature of the reactor. If Rossi want to improve the COP,the way to do it is to find another variable to control (as done by Defkalionwith spark plug). Nevertheless, your time domain work might help a lot.

Theseplots strongly resembled the ones that my model produced and I have longcontended that his limitation of 6 for COP is based upon stable operation ofthe system. This limit occurs as a result of the observation that adevice such as his has the ability to internally generate all of the heatrequired to run away unless it can be carefully manipulated. TheSSM period and level are key to getting the desired performance.
