2011 - Andrea Rossi Explains His Energy Catalyzer
(duration: 13m 24s)

Remarkable. In this video, at about 10:40, Rossi acknowledges that
there is a little water that, he claims, condenses in the hose.
"very small condensation, because this is very short, and so the
maximum part is steam, that goes out."
Krivit asks to see the steam. Rossi picks up the hose. He takes care,
quite deliberately, it seems, raising the hose first, I interpret
this as ensuring that water condensed in the hose runs down the drain.
He pulls the hose out, holds it for a moment in the air, puts it back
in the drain. Krivit starts sputtering himself, but Rossi
understands. Meanwhile Levi has come up with a black T-shirt or other
garment, which he holds up so that Rossi can hold the hose against it
and we can see the steam, at about 11:25. I'm not certain what I'm
seeing here. It seems to me sometimes that the steam is existing
invisbly for a very short distance, which would indicate dry steam.
Howver, sometimes I see the steam next to the outlet, this could be
related to the end being moved around by Rossi.
The volume of steam coming out seems low for the claimed power, just
my impression, easily could be wrong.
Rossi's explanation is not sound, that the steam isn't so visible
because it's so hot. It's at normal temperature for steam!!!
It will cool and condense, becoming visible, when it hits the ambient
air. The only difference that will exist for various flow rates will
be an increase in the plume size and an increase in the apparent
velocity of any turbulence in it. The margin between the opening of
the hose and the point at which the steam becomes visible will become
larger (because it probably takes about the same time to cool, but if
it's moving faster, it will travel further in that time.)
The instability of the viewing of the steam plume is disappointing.
I just looked again. I think I can see steam all the way down to the
hose, which would imply that this is not dry steam, not completely,
not exiting the hose. It might have been dry coming out of the E-Cat.
The place to observe the steam would be at the valve, which they have
completely covered here. The temperature inside the hose at the end
would be of interest. If it's cooler, that would explain the
visibility of steam.
(A tee with valves on both branches would do it. The hose would run
to the drain, as they have. To allow viewing the steam, they would
open the valve on the vertical section of the tee fitting, and close
the valve to the hose, wait a little while for the tee to heat up,
and then one could view the steam plume clearly, with a black
background, up very close. Nice test would be a small increase or
decrease in heater power, which should fairly rapidly lengthen or
shorten the position at which the plume becomes visible. I've
suggested having a steam whistle on the vent, for fun. But the flow
rate might not be adequate. Maybe a small whistle. Levi, by the way,
has a great deal of fun with the black T-shirt or sweatshirt,
clowning for the camera. Nice human touch.)
My inclination is to believe that the device is actually boiling all
the water going through, but that's got to be qualified by hedges. If
we could see that the steam exiting the E-cat was invisible, and that
no water was spitting out, that would ice it, and that should be so
simple to do that I'm left with what has become my default
hypothesis. Rossi is making weak demonstrations, and deliberately.
And, of course, Krivit is not made a witness to details such as
weighing the water input, etc. This is basically a "Trust me" demo,
which is his right, and we can even appreciate the opportunity to see
this, but I have to conclude that Rossi has no interest in convincing skeptics.
It's quite understandable. Either way! (Real/fraud.)
