The important information is: There is no superheated steam because
inside the ecat is everything almost at boiling temperature. For
superheated steam you need an extra heater that heats the steam and
there is none.
Because the temperature inside the e-cat is above 100 degrees the
boiling temperature inside must be above 100 degrees and therefore
the pressure inside the ecat must be above 1 bar.
I still think that the 2-chamber design explains more than the
1-chamber 3-bar design. The core could easily be engineered with a
water-efficient heat exchanger in one chamber, and a steam-efficient
heat exchanger in the other.
See my recent reply to Jouni Valkonen.
To maintain an internal pressure of 3 Bar (needed for 130C) you'd
need a pretty small orifice : less than 1/32 inch ?.

(Unfortunately, that's in engineering units .. I'll look for a metric version.)
And then you have to condense 5L/hour (3g/sec) in a 10cm pipe. (Rossi
says that all that 5L is from condensation, not overflow.)
I think Colin Hercus is on the right track, using a Finite
Element thermal model. I played with the Elmer system, but didn't
get very far with it, as it doesn't model steam very well.
