Your puzzling is puzzling, Harry.
Rossi is claiming (I think it was) 10 KWatts of power from a unit. There
are few practical ways to measure that besides (in essence) boiling
water. A gale of air?
I will give you, that Rossi may not have /simultaneously/ attained 600
degC and 10 KWatts. This is what an efficient electric power generator
needs, so a shortcoming here could indeed show puffery.
In either case, a useful device, at least for pool heating! How many
gallons can you keep at 10 degC above ambient, with 10 KWatts ?

I just want to remind people that the claimed operating temperature of
600C is not new. When Rossi presented the ecat in Jan 2011, he said
the core would reach temperatures around 600C, but the heated water
only just boiled. Now he claims the core is stable at 600C but he is
not doing anything with the generated heat. Is this progress or
puffery?

Recently it has been reported that the latest version of the Rossi ECAT can
operate at 600 degrees centigrade or more without going unstable. This is a
remarkable improvement if accurate and it is suggested that the proof will
be delivered soon.
The earlier versions of the device tended to become unstable when the
temperature increased much beyond the operational level and now that appears
to be under control. To operate in such a manner suggests that the
mechanism which establishes the LENR activity is mostly independent of
temperature of the device. Actually it might imply that now there is a form
of negative feedback operating which tends to throttle back the energy
generation process once a threshold temperature is reached.
I have long hoped that the driver source could become independent of the
output states in LENR devices since that would devoice the devices from the
strong temperature effects that have made stability a big problem to contend
with. Imagine how wonderful it will be if we are able to control the
reaction by just changing the drive with minor temperature degradations.
There has been a lot of recent activity related to carbon nanotubes and
variation in the waveforms driving the LENR devices. Perhaps Rossi has
found a good combination of hydrogen storage with release control and an
electrical signal that work together as a system. Time will reveal if all
or any of this is true.
Maybe someone within the group has knowledge of the operation of the
Patterson cells which seemed to use an electric current as the control
handle. Was that device sensitive to temperature in the manner associated
with positive feedback or more benign as would be expected if negative
feedback were dominate?
I for one would welcome the improvements in the Rossi device that have been
outlined, but have learned from experience that it is easy to say something
remarkable but then not follow up with the goods. Perhaps this time we will
see the results that we so much anticipate.
