Rossi E-CAT HT on natural gas?

if E-cat is used just as an amplifier of heat, it is right that gas is the best primary source, because in US gas is a competetitive source of electricity, but with an efficiency about 1/3...

note that Rossi claims a COP of 3 for gas version... anyway if you take from gas to heat, the COP of electric version is 2 (6*.33%), and 3 for the straight gas version.

problem of gas e-cat is that it cannot be looped as an energy source.

when I say looped I mean that like on a fission reactor, that electricity produced feed the reactor itself...
not feeding another reactor

chaining heat could be possible, but I'm afraid it is not, because of control and stability.
I suspect that the mouse and cat of rossi, take advantage of very tricky control theory (phase shift) to allow stability...
I'm also afraid that plugging an e-cat into a steam generator is not trivial...

Quote from faheem

Dr Mitchell Swartz (MIT) talks about the Optimal Operating Point which is a curve (manifold) that falls off quickly in both directions under excess power conditions. If too much heat is added or removed too quickly the excess heat disappears.Not a trivial design problem but quite feasible to do with a micro-controller.

Yes the question of that response transfer function is key to control and thus engineering.
that it falls of on the high side is a good thing for control.
My fear is that it is quite destructive on that side. If not, it allows stability.

what Rossi said recently, that the cat was getting cooler when the mouse was hot make me think of a 90° phase shift, explaining why there is a mouse and a cat... to make a negative feedback which is stable... only a guess...

the origin of the 90° phase shift is maybe that the heat is produced by flow of hydrogen in the material. some LENR scientist says nothing happens in stable condition, that it have to breath, with biggest example of "heat after death", where degassing cause massive heat release.

few people understand that what allows fission nuclear energy is that
1- neutrons are less absorbed at high temperature at some working point (and more absorbed at others like in A bomb, or in Chernobyl accident)
2- this retroaction is slower than fission, but hopefully there are delayed neutrons production which are slow too, preventing the reactor to go berserk before the reaction is cooled down.

it is the same for rocket solid fuel, which unlike explosive have to consume regularly, and thus burn less when pressure and heat increase.

control is one of the key of LENR, and Rossi had problems.

Brillouin according to recent mail from Sterling allan have also some problem at high COP.
