In one of the photos of the Rossi demo, Levi is shown holding his ear as if there was a loud noise coming from the device. OTOH he could have been listening to an inopportune cell phone call.
Does anyone recall an audible component to the demo (other than the pump sloshing) which could be indicative of lower harmonics of ultrasound? Of course, there is lead shielding which would shield for sound as well as radiation. The reason that this may be important is that thermistors are also piezoelectric (usually). We know the blue box contains five controllers, possibly an older kind of Allen Bradley controller, but that is a guess and not known. An expert might recognize the type of controller with the unusual exposed binding posts, but no mention of it has surfaced AFAIK. I think that the controllers drive thermistors with pulsed DC, instead of heating tape, which is the usual assumption. "Positive Temperature Coefficient" (PTC) thermistors function as self-regulating heating elements with only two wire input. They can work like thermocouples by sampling impedance in the circuit several times per second when controlled by PLCs. The point being, if this is correct, one would expect ultrasound as well. Anyway, I was calling this setup “PLC/PTC” since it could be PLCs driving thermistors… and now it has been realized that, if accurate, there is a possible new variable to the input – ultrasonics and possibly a travelling wave, due to five controllers, when if the requirement was only for temperature – one would be sufficient. Other reasons for this suggestion is the Energetics Technologies (Dardik) SuperWave™ and the other evidence of sonofusion and/or sonoluminescence. Now, back to the original question about Levi at the demo – is there evidence of an ultrasonic component? Jones
