This is a long post putting together several threads of evidence that the
Rossi reactor is a cavitation reactor.
Pressurized hydrogen in contact with nickel nanopowder is cavitated,
eventually undergoing first chemical and then nuclear reactions, with
copious excess heat. The Casimir effect could be involved in a novel way for
the chemical part. Fractional hydrogen could be involved. The nuclear part
is confused by conflicting reports about radioactivity. Best bet is that it
is the "Ra Reaction" of our sun - conversion of hydrogen into deuterium, but
that is speculation for other posts.
An appreciation for the history of the Griggs pump is necessary to grasp all
of this. Here is some information on the pump, which is still in commercial
production in Rome (the one in Georgia):
The Hydro-Dynamics pump employed cavitation and shock waves from a dimpled
rotor spinning inside a housing to increase the temperature of water flowing
through the device. It was tested on a number of occasions to be OU, but not
reliably. Jed Rothwell has reported on it, as did Infinite Energy. Now -
imagine the rotor being non-rotating !
Cavitation in the Rossi device could be described as Griggs pump - with the
reactor substituted for the dimpled rotor. The reactor cavitates violently,
but at low excursion, and would not be noticed in a demo, since the effects
are dampened by the water flow. Primarily, it produces cavitation INSIDE the
cell, and ironically this would never have been noticed outside the cell
except for contrasting the two tests in Bologna, one with low water flow,
and one with high. This could be a most fortuitous discovery for anyone
working on a replication.
The higher water flow is substantially more efficient than low flow - and
the reason for that relates to Griggs and to optimizing cavitation. The
outer surface of the reactor would be the functional equivalent of a
transducer to cavitate the water flowing over it, but only if the water
pressure was high enough. The Griggs pump needs massive water flow. The
internal cavitation is not changed much in either case, so there is always
that base level of heating due to internal cavitation. The "clue" that
cracks the case - turns out to be in contrasting the two test results in the
context of a heated argument.
Magnetostriction is a property of ferromagnetic materials, particularly
nickel - that causes them to change shape during magnetization. It was
discover by Joule himself, in nickel, long ago. The effect is responsible
for the familiar "hum" which can be heard near transformers at 100 (=2*50)
or 120 (=2*60) hertz, plus higher harmonics. Transformers are iron based,
but nickel nanopowder could be much more extreme in the effect. With the
very high excursion of surfaces at the nano level, the magnetostriction
effect would be magnified by perhaps an order of magnitude and yet nearly
imperceptible at the local level.
The reactor containing the nanopowder would function like a humming
transformer core and it could also operate internally with shock waves
pushing hydrogen into Casimir cavities. As in the Griggs pump, cavitation
generates shock waves which convert mechanical energy into acceleration and
eventually into heat energy - in a way that is gainful at times. The Rossi
reactor is apparently gainful all of the time, and that could be due to the
employment of nano geometry. Many of the common transducers used for
sonochemistry are magnetostrictive instead of piezoelectric, as these are
more robust at high input. The efficiency is very high.
It is too much of a coincidence that the reactor loses it heating effect at
a temperature which coincides with the Curie point of nickel, and is more
robust when more heat is removed by higher water flow; not to mention that
the "resistors" have a magnetic field. An interesting point is that the
inventor may have discovered this inadvertently and never thought to
optimize the input power, which should be easier to do via an inductive coil
instead of resistance heaters.
If this proves accurate in a replication effort, then my thanks go out in a
general way, to all of the Vortex posters who have mentioned these details
in past postings, as I have not had the time to go back to credit them
individually - you know who you are :-)
