Yes, I meant that it would be more convincing if a smaller device was used 
(10's to 100KW) and that 
it turned a steam engine, stirling,.....   that could convert the heat and it 
then could be run without any
access to external power sources.  
Notice I do not wish to imply that the water flow also be required to be 
powered by the device.


I don't see much advantage in going from an uncontrolled 10 kW demo with no 
control and little
instrumentation to a 1MW device with no control and even less instrumentation 
with no
chance of independent verification of the measurements and check by first 
principles.

I would expect you would have to have some external power source to start the 
device.

I don't see the risk in the electrical conversion conversion failure.  I don't 
think that the device 
would fail to disaster  if the stimulation/heater/ whatever  (80 or so Watts 
used in the demo)
would be removed.....  Perhaps if the cooling water is turned off but not the 
stimulation.

A self powered device that heats a water flow would be fairly convincing - if 
run
for an extended time.

I think Cravens meant Rossi should use the heat to generate electricity and 
make the device self-sustaining. He added: "If his claims are real, he should 
have enough gain for that even at only 5% conversion rates."


That probably refers to thermoelectric generator conversion rates.


I don't think he meant the machine should be literally unplugged. As you said, 
that is reportedly dangerous. That is why I suppose the control electronics 
should have a battery back up system. 


I think it would be unwise to make a thermoelectric generator and a completely 
stand-alone machine at this stage. For safety's sake, AC input with a battery 
backup is the most reliable, tried-and-true method. Stand-alone operation would 
not prove anything that 1:200 input:output ratio does not already prove. A 
skeptic who would question the 1:200 ratio would also doubt that the 
thermoelectric stand alone machine is what it appears to be.


If it were safe to turn off the power completely, then perhaps a thermoelectric 
stand-alone machine would be a good idea.


In the future, after the technology matures, a stand alone self-sustaining 
machine should be perfectly safe. I'll bet it will still have a battery though 
. . . for decades to come. It will be needed for safety and also for a cold 
start, assuming anyone ever shuts down one of these things. (Why would you? 
Maybe for maintenance or to ship it before installation.)
