Nothing changed. Calorimetry WAS done. The method used to do it was different, but just as valid.
Also, why does he need to use three phase A/C on the heaters? A heater is seen electrically as just an inductive resister so using three phase makes zero sense, except for those who failed in A/C math in electronics. It's a lot harder to calculate power used with a simple meter even an RMS meter. I'd rather use I x V=W than bust out the trig necessary to accurately measure A/C."
Because three phase is ultimately more efficent use of electricity. It doesn't matter, because they measured the current draw on each phase UPSTREAM of the control box. What happens in the control box is basically irrelevant to the COP determination.
"They should have used D/C, measured the voltage and current and bingo, you have power in without having to worry about phase angle or all the other things measuring A/C current accurately has in its way whenever reactance is involved."
Rossi uses what he wants to. The three-phase setup is almost certainly how deployed commercial devices will be driven. Why should he use DC for a demonstration??
"They did use single phase A/C for one of the other experiments."
Yes, because that is easier to implement. The three-phase version of the circuitry probably wasn't designed yet.
"What ever happened with Defkalion?
I'm sure we will hear from them soon, and from many of the rest of Rossi's competitors, as well.
This sure sounds like technobabble:
… a cylinder having a silicon nitride ceramic outer shell, 33 cm in length, and 10 cm in diameter. A second cylinder made of a different ceramic material (corundum) was located within the shell, and housed three delta-connected spiral-wire resistor coils. Resistors were laid out horizontally, parallel to and equidistant from the cylinder axis, and were as long as the cylinder itself. They were fed by a TRIAC power regulator device which interrupted each phase periodically, in order to modulate power input with an industrial trade secret waveform. This procedure, needed to properly activate the E-Cat HT charge, had no bearing whatsoever on the power consumption of the device, which remained constant throughout the test. The most important element of the E-Cat HT was lodged inside the structure. It consisted of an AISI 310 steel cylinder, 3 mm thick and 33 mm in diameter, housing the powder charges. Two AISI 316 steel cone-shaped caps were hot-hammered in the cylinder, sealing it hermetically.
Not technobabble at all. A perfectly straightforward description of the construction of the device. Nothing odd there. The choices of materials do tell me that Rossi is targeting VERY high temperature operation eventually.
"Was there radiation detected, did they mention lead shielding, analysis of the end product of the reaction?"
I didn't see that mentioned, but Bianchi did radiation measurements on the earlier tests of the hot cat. His results are available online.
"So, now it's not a secret catalyst, it's a secret waveform which would be incredibly easy to figure out. Rossi changes his tune every time we hear him. His responses to the questions from the Florida certification folks are awesome in their complete B.S.
"Not mentioned" is not the same as "not used". And why would Rossi give out his most valuable trade secret(s), as his IP protection is very weak.
"He is doing nothing but damage to legitimate LENR/LANR research."
A lot of people involved in the "legitimate LENR/LANR research" field disagree with you.
