Mark not sure how you conclude this:
(1) Rossi has described his setup in published papers, it is as P has said - and the wrong calculation (also published) clear.
(2) The given equipment can only measure current (and hence power) if a sense resistor is included - that also makes sense of the ohm-meter.
(3) Paradigmnoia is not always right - who is - but he should always be taken seriously.
To be more clear, in the Gullstrom paper photo there were two digital multimeters and an oscilloscope. A DC power supply was also in the Gullstrom photo. The same oscilloscope and maybe one of the multimeters was also used in Stockholm. As far as we were shown, the multimeters were both in DC mode, and were measuring the voltage (drop) across the 1 ohm resistor in the Gullstrom photo. (I don’t think anyone has strong doubts that the 1 ohm resistor was exactly that). The oscilloscope was shown measuring high frequency AC voltage across the 1 ohm resistor in Stockholm, with a small DC offset. The AC component cannot be measured across the 1 ohm sense resistor with a DC multimeter setting. A True RMS AC voltmeter is required to measure AC voltage properly. And yet only the DC component was used to calculate power (dissipated by the sense resistor, not the plasma circuit) for the Gullstrom papers, while the AC part (if any) was ignored. In Stockholm, both the AC and DC parts of the sense resistor voltage were displayed. In both cases the voltage (drop) across the sense resistor was used (wrongly) as if it were the plasma circuit voltage, and also measured the current (as the sense resistor is intended). This means that the heat power output of the resistor, not the power of the plasma circuit (ignoring the controller circuit) was calculated.
This can easily be tested by anyone with rudimentary electrical knowledge, a ohmic load of greater than 1 ohm, a 1 ohm resistor, and a decent digital multimeter. Mizuno properly used a sense resistor. If he used it the Rossi way, his blower fan would show a COP of about 6.
