Thanks -- this actually sounds interesting. I had long since stopped
following Rossi at that point (after concluding that his tests four or
five years back were clearly fraudulent) and so I missed it.
If you can find a report on it I'd appreciate it. No rush, though! I
have other stuff I'm supposed to be doing tonight, rather than
dissecting one of Rossi's old tests.
Anyhow I'd actually find deconstructing that a lot more interesting than
deconstructing the year-long test. If you know of a paper on it, with
things like graphs and tables and actual data, that would be great.
(For the record I do not doubt that the test took place! I doubt the
results were as they appeared, but that's something else again, and it's
based on the Uri Geller effect -- once someone is proved a liar I doubt
everything they say, so if Uri Geller claims something now, I doubt it's
true. If he does a demo for some scientists, and they believe it's all
true, I doubt they're right. But that doesn't mean it's not interesting
to go over it and try to find the glitches.)
It was well publicized and included a several day period during which
the output was set to a fixed power. During the test the input power
being supplied to the device was slowly dropping as presumably more
excess power was being generated. A temperature sensor was attached
to one end of the device which fed back that information into his
control box. Does this ring any bells?
I suppose we can search further if you really doubt that the test took
place. I feel a bit lazy at the moment.

I recall Rossi discussing power control on numerous occasions.
Why would he hire control experts if that were not the reason?
I don't know why he does anything. I was asking for a specific
assertion. AFAIK he never made such an assertion.
Do you think that anyone would have taken him seriously for any
significant period of time had he not discussed that issue?
People who looked seriously at his output power curves stopped taking
him seriously years ago. So, this objection is not relevant.
It seems a bit unfair for anyone to state that Rossi runs his
systems open loop especially when you should recall the HotCat
test performed by respected scientists. They took notes which
clearly showed the input power being throttled back in time as the
output power was maintained at a constant level. This is the
obvious finger print of negative feedback.
No, I recall no such thing. In fact Rossi did indeed supposedly run
his demos open loop four or five years ago. He set the input power to
a fixed value and then showed the output power ramping up to a value
several times the input.
And this appears to be the same, exact system, just replicated many
times. So, the assumption that there's feedback in it now seems
unsupported, just like the assertion that there's a recirc pump which
is pulling the pressure below 1 atm at the other end of the steam pipe.
And no, I don't recall any clear report by independent parties that
the input power was definitely throttled back while the output power
remained fixed. Please give a specific example -- I really recall no
such thing.
There were a handful of more or less independent tests; presumably you
have one in mind. Which?

Is this known to be a fact? Has Rossi actually described in some
reasonably clear way, rather than just giving a handwave to a leading
question about feedback?
Where does this information come from? What was the feedback
parameter
(i.e., what temperature probes were used) and what, exactly, did it
control, and how?
I know a lot of people have assumed this, but I have never seen it
stated as a fact, and I have never seen it claimed by Rossi.
