As Andrea Rossi prepares the first Hot Cat for the market place, he evidently continues to tweak and improve the technology. In response to an inquiry from Bernie Koppenhofer on the Journal of Nuclear Physics, Rossi commented on the place of the Carnot Cycle in E-Cat and Hot Cat technology.
Koppenhofer commented:
“Electricity directly from heat seems to be a much more ‘natural’ way to make electricity, compared to the Carnot Cycle. Your hot cat seems like the perfect heat machine. Are you making any progress in circumventing the Carnot Cycle to make the ‘PowerCat’?”
Rossi’s response was quite interesting:
“You are touching a very important point: during these very days, and also during the more recent tests, we are working on this issue. I think we will be able to produce directly e.m.f., but much work has to be done.”
The e.m.f., or Electromotive Force, is based on Faraday’s Law. According to Hyperphysics, e.m.f.:
“…represents energy per unit charge (voltage) which has been made available by the generating mechanism and is not a ‘force’. …It is useful to distinguish voltages which are generated from the voltage changes which occur in a circuit as a result of energy dissipation, e.g., in a resistor.”
In this application, the “generating mechanism” referred to in the definition is Rossi’s Hot Cat.
Rossi continues:
“Actually, we already produced direct e.m.f. with the reactors at high temperature, and we measured it with the very precise measurement instrumentation introduced by the third party expert, but we are not ready for an industrial production, while we are at a high level of industrialization for the production of heat and, at this point, also of high temperature steam, which is the gate to the Carnot Cycle.”
While the Carnot Cycle is still part of the calculations and performance of the current Hot Cats, it is apparent that Rossi is working, with some early success, to circumvent the Carnot Cycle entirely.

OK where is an actual working as advertised Ecat?
Who has one?
Which independent lab has verified it works as Rossi says it
should work?
Where is it?
The carnot cycle is a basic heat engine equation and HAS NOTHING to do with
a NUCLEAR REACTION!
So the Rossi device works on a chemical reaction?
Which the Carnot Cycle models?

While it is very very interesting that it is a theoretical possibility that a LENR reactor could produce electricity without converting heat through the (inefficient) Carnot process, the overwhelming importance now is replacing coal and natural gas boilers in currently operating electrical generation plants. First generation LENR will inevitably be industrial replacement of fossil fuel, as this is the least disruptive most profitable use. Once the paradigm of fossil fuel => heat => mechanical force => electricity is replaced by LENR => heat => mechanical force => electricity, then the market forces will be brought to bear on other LENR applications.
Although technological advancement is exponential, the beginning of an exponential curve looks linear, and a new technology always starts slower than you hope, then spreads faster than you expect. For instance, land line phones took over three decades to spread far and wide, but cell phones took less than a decade, but if you look at the R&D, they both took about the same time to refine their respective technologies.
In my opinion, one of the primary negative feedback loops to the introduction and adoption of new technology is psychological. The good news is that the adoption of new paradigms is doubling each decade. Again, using large LENR reactors to replace current fossil fuel boilers is the first step to overcoming the psychological barrier to this new paradigm, and refining this technology to make that first hurtle successfully will take more time than the adoption of LENR once that first barrier is breached.

NO entiendo una cosa Rossi en Italia sobre todod en milano era considerado un charlatan porque prometio sacar petrolio de la basua ya l final no lo hizo.
Solo espero q no sea una cojida de pelo un cuento porq si es verdad su invencion todo sera mas facil para todos exepto los petroleros

Minos, Rossi was tried and jailed (briefly) because the laws changed and what he did become unlawful.
He produced oil and fuels and he sold them to his clients.
The stuff Rossi used was classified as “dangerous wastes” by the law and become unlawful to use them to produce anything (before they were legally usable).
They could only be burned in some incinerators or buried in approved landfills.
