here was your misunderstanding. This is not true, because water input
is at the same level as reactor core, but water output or boiling
surface is above the reactor core somewhere in the chimney.
This statement seems nonsensical. Water boils (coverts from liquid
to gas) at the surface interface where the *heat transfer* takes
place, in this case on a metal surface. The heat transfer should
therefore be occurring where the heating elements are mounted, and,
providing nuclear heat is being provided, at the metal surface of
the Ni containing compartment.
Rossi himself would clearly agree with you. Rossi's statement in the
video:
http://www.youtube.com/watch?v=m-8QdVwY98E
also seems nonsensical. At YouTube time 9:36 he states: "This is the
chimney. At this point the water is evaporated, because here we are
above 99.9 C degrees, the limit of the liquid state of the water."
He also states: "This is the thermocouple that measures the
temperature of the *water* in the chimney."
This makes me wonder if you are actually Rossi or work for Rossi!

Rossi made here at one time. A conspiracy theory.)
There seems to be a major error in understanding going on here. Steam
bubbles clearly will move through the chimney, assuming water temp is
100 °C, but they do not originate there. Steam is not generated there
unless some source of heat is provided there. The origin of any steam
is where energy is being supplied, which in the case of the E-cat is
the horizontal section. This means bubble formation is occurring in
the boiling chamber, and oscillating flows as well as mixed gas/
liquid flows are occurring in the chimney.
Given there is water in the chimney then a percolator effect is
obviously likely.
You forgot that the chimney makes it tea pot like and essentially
vertical in structure. And the more powerful is the reactor, the
taller and wider the chimney must be, so that it can contain several
liters of water. That reactor type what was used in most recent
demonstrations used shorter chimneys, but also the input output power
ratio was much smaller and more predictable, so that it can be
controlled by adjusting input water flow on proper level, although
short chimney's ability to buffer water level is drastically limited.
As I noted in earlier posts, this short chimney, provided the
controller momentarily reduces power output sufficiently, will permit
the water to overflow the chimney into the hose, due to the constant
pump rate. Provided the power provided is at least 600 W the water
temperature in the chimney should not be affected at all, wile about
2 cc/sec is pumped out the top of the chimney and overflows, falling
down through the hose. For those that care, I use the word
"overflow" here with deliberation. See:
http://www.thefreedictionary.com/overflow
However, if any steam is being produced at all, then the bubbling
effect will cause a percolator effect that causes the overflow in
small increments, producing a gas/liquid mix output.
So next time you boil water for tea in the kettle, please measure the
dryness of the steam! E-Cat produces _exactly_ as dry steam as your
tea pot!

A tea pot has no means to overflow. Water is not continually added.
It is also not designed like a percolator, with large confined
boiling compartment, and a narrow short chimney.
The Rossi device is a horizontal boiling chamber followed by a
vertical tube and elevated ejection port. This is essentially a
formula for a percolator that can continuously operate at boiling
temperature, provided a minimum of 600 W required is supplied.
A percolator can produce liquid mass flows far exceeding 1% by volume
of gas. The amount of percolation obtained can be controlled by
controlling the ratio of the flow of water to the amount of heat
applied to the chamber. Active controllers exist in the Rossi device,
thus may do this.
Something that would obviously be helpful for demos would be the use
of translucent tubing, such as polyamide (nylon) tubing, which is
good up to 100 °C, instead of black rubber. See:
http://www.graylineinc.com/tubing-materials/nylon.html
A transparent U-trap just past the current steam exit might prove
informative.
Rossi's main claim of utility is excess heat. Yet no one has made any
effort at even very basic calorimetry measurements on the output.
It is incredible that it could be expected that anyone would invest a
dime in this technology without even the most basic and inexpensive
science being applied to the most important aspect - calorimetry on
the output.
