Parkhomov has addressed the primary concern that I had with his experiment
(power levels required to bring it up to the temperature needed to initiate
the reaction).  Additionally, he confirms something that Rossi recently
stated about it being possible to restart the reaction after it has cooled.
And it is reported that he affixed a thermocouple on the outside of the
cell, alleviating that concern.

On ECW, it is noted:

"Dr. Parkhomov reports that the target temperature of 1200ºC in the fuelled
reactor was achieved by the time the electric power had reached around 600
W (in contrast to 1070 W needed to reach 1200ºC in the dummy). Then within
an hour, the regulator had decreased the input power to just 330 W to
maintain the same 1200ºC. Approximately, this has been the power required
to during the whole operation of the reactor.

It is difficult to grasp the significance of this information.
Dr. Parkhomov, Thankyou."

Possibly, this also addresses Dave's concern based on his models, but he'll
have to weigh in on that.

As long as the 600W wasn't more than was needed to reach 1070C, then you
get a minimum COP of 1.8 (treating the experimental cell heat up power as
its own control).  I hate to nitpick, but it would be good to know what the
max temperature would be if using 500W (e.g., 950C).  The good thing is
that the reaction will restart.  He can turn it off again, and run 500W
until it levels out at a maximum temperature.

This is getting very close to ruling out alternative explanations.
