I agree that 1 phase would be adequate to handle the present situation.
Remember, this unit is going to be part of a much larger megawatt device and it
would not be unexpected for Rossi to be thinking of the total picture. We need
to be careful and realize that this test is not of a total system.

Eric makes a good point though. It therefore looks like there exist at least
two separate mains outlets in the lab - one being 3-phase for the experiment,
and one being conventional single-phase, which is what the laptop adapters will
expect. I am surprised that 3-phase is deemed necessary, because at the power
levels being pumped in the experiment, single-phase mains is wholly adequate,
up to a few kilowatts.

A transformer is not needed. Solid state switching regulators are used in
most cases to handle the input voltage across filter capacitors following
diode rectifiers. Safety is achieved by floating the input relative to the
output voltage generation circuitry. I would expect to see pf correction in
a modern application once the dust settles.

B) seems unlikely because it would require batteries, and Hartman states
that it was much lighter than that. Battery technology does not exist that

only workable theory of possible deception is A).
I recall Hartman clarifying that measurements were taken on the mains side
(from Jed's post). I am not too familiar with circuitry. I assume that
either (1) the measurement equipment (including the laptop) will need some
kind of single-phase conversion in order to work off of the same mains, or
(2) they will have to be routed to a separate source (in the case where the
mains side has been tampered with). Assuming (1) for the moment, how easy or
hard would it be to filter out hidden DC or AC when constructing the single
phase conversion in order to protect the measurement equipment? Would you
need a heavy transformer?
