I went back and looked at the Levi interview
(http://www.youtube.com/watch?v=0vYJIG3ymOk starting at 3:00). Levi says:
3:00 feb 2011 test w/o steam
4:00 "system started in an almost explosive way"
6:00 "15 kw for 18 hours"
6:20 "we connected the system directly to the water pipe with flux
[flow] measuring 1 liter/second"
6:50 "almost 40 degree delta t -- if you make calculations this is
about 120kw"
7:11 krivit: "what was the power input?" levi: "less than 1 kw"
7:18 "rossi was very worried about that and damped (dumped?) the
system and restarted the system and obtained about 40kw"
7:50 "i will not write up that test"
15:00 still arguing with krivit about whether to write up the feb 2011
test
My sense is that the core was in thermal runaway, and that even at 1
liter/sec they could not cool it enough to get it stable. Rossi then
'dumps' the system (unspecified as to how), quenching the reaction.
My guess is that this configuration was not possible to recreate on
demand -- it was apparently an unusual event.
Anyway -- there are possibly many reasons why a second test of this sort
was not performed, not least of which may have been Rossi's disinterest.
But my sense is that running the system with liquid water at 1 atm. is
not easy, hence Rossi's use of a steam-to-water heat-exchanger in October.
Mary -- I see that you are helpfully skeptical of much of what Rossi is
putting out. But what I'm missing is a coherent narrative of what you
think is happening. You know, people put out theories about how 9/11 was
an "inside job" by pointing out all the inconsistencies. But can they
put together an alternate narrative that fits the discrepancies and
makes sense?
I'm not saying that if you can't do this Rossi is not faking it, but it
would be nice to hear a coherent story that you feel explains what is
going on.

Well, didn't you just say Levi's experiment alarmed Rossi by running
too hot? With liquid coolant, you can control temperature by varying
the flow rate of the coolant which is easily done with a manual or
automatic valve or even by varying the pressure head of the fluid by
simply raising and lowering the container! It's a snap. I used to do
something similar when calibrating calorimeters with liquid coolant
jackets. And Rossi has claimed that regulating the hydrogen pressure
also controls the reaction. Getting a decent coolant flow and delta T
should be very doable with a bit of experimenting.
