The 2 COPs of the E-Cat

From what Andrea Rossi has been saying recently regarding the upcoming presentation, I think we have some idea of what to expect from the upcoming presentation. Rossi is not going to focus on the overall COP of the complete apparatus, which includes the control system and the circuit in which the E-Cat QX reactor(s) are located, his goal is only to demonstrate the COP of the E-Cat QX itself.

Jaroslaw Bem:
The COP is given from the ratio between the energy produced by the E-Cat and the energy consumed by the E-Cat, independently from the energy consumed by the control system.
The control system consume is made by the heat in which the flowing electricity is dissipated, that obviously cannot be accounted for the COP of the reactor.  The thermal energy in which the electricity of the control system is converted can be recovered itself, with a COP close to 1, if opportune, because the heated air can be sent in a preheater of the water before it goes to the reactor. It is just standard air/water heat exchange and it can recover practically all the energy dissipated by the control system. This, obviously, does not change the COP of the reactor.
To reach a COP>1 adding the energy consumed by the control system is enough 1 E-Cat QX.
Warm Regards,


He does note in the last sentence of this response that if there was only one E-Cat QX, that the whole system (including the control system) would have a COP higher than 1, which implies that the power consumption of the control system is less than 20W (the power rating he has provided for a single E-Cat QX. I have asked Rossi to confirm this, but so far he has not. If this control system can operate up to 100 QX reactors, then one would assume that the more reactors that are combined, the higher the overall system COP would be. Another quote:

Michael S.:
First and foremost, thank you for your kindness and attention to our work.
Answer: the energy consumed will be measured AFTER the power source, which means between the power source and the E-Cat ! From where arrives the energy to the power source or IN it doesn’t matter to the COP: what matters is only the amount of it. If it arrives from a battery, or a series of batteries, or a multiple sandwich of batteries, or from a magician, or from the grid, therefore from a dam, or a nuclear plant, or a thermoelectric plant, or yourself in parallel and series with friends of yours rubbing frenziedly, even with the help of me hidden behind black courtains, a stock of amber sticks, it couldn’t affect the COP. What counts is how many Wh/h arrive to the E-Cat, not their origin.
About the plat you suggest, it will be fun when the E-Cat will go commercial.
Warm Regards,

Since Rossi states that the power consumed by the control system is immaterial for the purposes of demonstrating the COP of the E-Cat itself, and since he has also stated that he considers it confidential, I don’t think that we will see measurements of the control system’s power consumption in the demo. He has said that this will be a “technological” demonstration, not a commercial one.

However, when it comes time for commercialization, it will be very important for customers to know the power consumption of the whole system, including the controller and any other appended electronics, so they know how much money the might be able to save, and how much power the system will consume.  So the overall COP of the system is ultimately going to be most important when it comes to practical application of E-Cat technology.
