Yes, Hall effect clamps are readily available, I am not disputing that.
They used to suffer from drift problems, but these problems have pretty
much been solved. The one that you show has a 3% accuracy and 8 digits
of drift - not bad.
The only info I have about Rossi came from a single post on

You mean an annoyance like the advance of the perihelion of Mercury? :)
OK, once again you furiously misunderstand. The isolation capacitor is in
series between the grid transformer and the wall plug. Behind the wall plug,
downstream of that capacitor, a DC power supply is connected in a T

Almost. The power being fed to the heater exceeds that measured at the

direct current being drawn from the wall

By direct admission of the team, posted here, it did not occur to them to check
for a DC level change
by the way, not a bridge but a single wave (one diode) rectification...
usual bridge does not cause asymetry, neither double wave.

If you want to sneak DC into a system, you'd never get it passed a clamp meter,
if you just use some diodes. You'll need serious decoupling. I say serious,
because the load is substantial and will quickly drain the reservoir
capacitors. Any ripple on the DC will generate a varying magnetic fiel
