I did not understand well, especially the theory papers. The experimental

*If you remember some time ago, I was concerned that the LENR reaction
would produce a boatload of muons since Holmlid suggested that LENR might
be based on ultra-dense hydrogen. But over the course of time, this concern
was not well founded, even though it should absolutely be the case. Just
like the absence of gamma rays, positrons, and neutrons, this lack of
products that should accompany any nuclear or sub-nuclear reaction that the
LENR reaction should produce is profoundly confusing.*

*Furthermore, from studying LENR results over the years, it is becoming
increasingly apparent to me that LENR has a major issue to deal with. LENR
makes matter and energy disappear. A major problem with LENR reactors is
that they fall apart over time. This highly corrosive effect that these
reactors suffer is due to this nasty issue of matter and energy
degeneration. This degenerative process only gets worse when the power
output level of the reactor goes up.*

*And yet the amazing contradiction that the LENR reaction presents is that
it does not produce any high energy particles or ionizing radiation. The
question that hangs in the air is where does all that matter and energy go
when the LENR reaction is active?*

 *At this current juncture, the reactor meltdown/corrosion problem has
delayed any LENR application from reaching a successful conclusion. LENR is
highly corrosive of the structure of the reactor as a function of its power
output. Clearly, LENR's ability to corrode the structure of the reactor is
a function of its power output. A low powered LENR reactor will function
for a long time but its usefulness is limited. A high output reactor even
if it is built like a tank does not perform for very long.*

*The lack of nuclear reaction byproducts and the corrosion issue might well
be connected.*

*In addition, I think that transmutation happens when the LENR reaction has
completed. For some unknown reason the LENR reaction in the LION diamond
was episodic. There were three episodes when the LENR reaction came alive.
Each of the episodes of activity produced a different transmutation
product. But at the end of each episode of activity, each time the
identical transmutation product was deposited at the ends of many tunnels.
The miners were all contained inside the tunnels that they excavated. But
they all behaved identically and communicated. They all acted in concert to
transmute carbon into identical elements when they were active.*

*From what we saw how the miners worked inside diamond, the transmuted
elements are held in invisible suspension through QM superposition inside
the flux tube until the LENR reaction had completed. Then the transmuted
elements stabilized into their final form. We saw the diamond disappear as
the miners excavated the tunnel, Then when the LENR reaction finalized, the
transmutated elements appeared at the far end of the tunnel.*

*When I considered what happens to the matter that the miners excavated
from their tunnels, I got confused. There are spaces inside those
completely closed tubes. Where did that matter go? Where did the energy
from transmutation of carbon go? There was a lot of transmutation but very
little if any damage produced by heat evident inside those tubes. The
matter that was removed from those tubes could have supported the energy
needs of a city for a year is it was transformed into energy.*

*Here is my take on this issue. I believe that LENR involves the
interaction of two major cosmological principles: Quantum mechanical
superposition and general relativity. Through looking at the results of
some recent LENR experiments, it appears that during the LENR reaction,
time stops inside the Black EVO as discovered by Ken Shoulders. When LENR
active processes occur, such as transmutation and superposition/tunneling,
they occur under a condition where time is not moving forward. This
superposition proceeds as a macro level quantum mechanical process that is
occurring were both material and energy in bulk is made to dematerialize or
tunnel possibly in a state of coherent superposition. This coherent
material may be removed in a condition that is out of sync with normal
matter and time and being in the state of superposition not able to
interact with its previously normal form except through the force of
gravity. Remaining perpetually coherent, it is a 

[Vo]:If Mizuno is correct, this design is likely to be the precursor to all future devices

[Jed Rothwell]

I believe that if Mizuno's results are correct, and especially if Ed
Storms' theory is right, this design will be the precursor to all future
devices. As I usually do, I look back at other technologies. The first
transistor was the precursor to all subsequent devices, even though the
methods of making them changed rapidly, and even though the material
changed from germanium to silicon. The first airplane was the precursor to
all subsequent airplanes.

There were many different approaches to building airplanes circa 1900, such
as A. G. Bell, Maxim and Lilienthal. Those were smart people. Their ideas
deserved respect, although the efforts did not make much progress. However,
in 1906 the Wright patent was issued. All successful airplanes after that
have been based on their discovery, which was 3-axis control. Also, all
successful airplanes have wings with chambers similar to this, and similar
length to width ratios. These are very different from Lilienthal and other
early attempts. The Wrights were superb engineers and they had rigorous
proof these were the best chambers and ratios, at the low speed their
airplane was designed for.

In other words, every airplane after 1906 is a descendant evolved from this
design, and all other precursor designs are extinct.

Needless to say, there has been tremendous progress in aviation. There was
tremendous progress between 1908 and 1914. By 1914, there were airplanes
that could fly 6 passengers for hours, going thousands of miles. Outwardly,
they looked completely different from the pusher design of the Wrights,
with the elevator in front. But from the engineering physics point of view,
they were similar. They owed the Wrights royalties for the patent.

If the Mizuno design actually works and it is widely replicated, it will
probably be the starting point for all future designs, just as the 1906
Wright patent design was. But there will be tremendous progress. It is
likely there is fundamentally only one effective design, just as there is
only one way to control an airplane (with 3-axis control). Future designs
may look very different outwardly, but the microscopic morphology and other
details of the surface where the reaction occurs will probably be similar.
Especially if Ed is correct, as I hope he is. Ed tells me he thinks this
morphology can be created with techniques similar to those used to make
microscopic integrated circuits.

[Vo]:RE: SPIN-LATTICE COUPLING

Latent heat is associated with a thermodynamic system.

See the following discussion from Wikipedi:

“A thermodynamic system is a group of material and/or 
radiative contents. Its properties may 
be described by thermodynamic state 
variables such as 
temperature, 
entropy, internal 
energy, and 
pressure.

The simplest state of a thermodynamic system is a state of thermodynamic 
equilibrium, as 
opposed to a non-equilibrium state. A system is defined as quantity of matter 
or a region in space chosen for study. Everything external to the system is 
surrounding. Thermodynamic system and surrounding is always separated by the 
boundary.[1]

The system can be separated from its surrounding by a wall or without a wall.

When the state of its content varies in space, the system can be considered as 
many systems located next to each other, each being a different thermodynamical 
system.

A thermodynamic system is subject to external interventions called 
thermodynamic 
operations; these alter 
the system's walls or its surroundings; as a result, the system undergoes 
thermodynamic processes 
according to the principles of 
thermodynamics. (This account 
mainly refers to the simplest kind of thermodynamic system; compositions of 
simple systems may also be considered.)

The thermodynamic state of a thermodynamic system is its internal state as 
specified by its state variables. In addition to the state variables, a 
thermodynamic account also requires a special kind of quantity called a state 
function, which is a function of 
the defining state variables. For example, if the state variables are internal 
energy, volume and mole amounts, that special function is the entropy. These 
quantities are inter-related by one or more functional relationships called 
equations of state, and by the 
system's characteristic equation. Thermodynamics imposes restrictions on the 
possible equations of state and on the characteristic equation. The 
restrictions are imposed by the laws of 
thermodynamics.

According to the permeabilities of the walls of a system, transfers of energy 
and matter occur between it and its surroundings, which are assumed to be 
unchanging over time, until a state of thermodynamic equilibrium is attained. 
The only states considered in equilibrium thermodynamics are equilibrium 
states. Classical thermodynamics includes equilibrium thermodynamics. It also 
considers: (a) systems considered in terms of cyclic sequences of processes 
rather than of states of the system; such were historically important in the 
conceptual development of the subject; and (b) systems considered in terms of 
processes described by steady flows; such are important in engineering. “

This begs the question: Do nuclei with internal energies constitute part of a 
larger thermodynamic system?

I consider the answer is yes. since they are linked by EM forces and in 
particular magnetic fields.

Recalescence is an increase in 
temperature that occurs while 
cooling metal when a change in structure 
with an increase in entropy occurs. The 
heat responsible for the change in 
temperature is due to the change in entropy. When a structure transformation 
occurs the Gibbs free energy 
of both structures are more or less the same. Therefore the process will be 
exothermic. The heat provided is the

result of a decrease of potential energy and an increase of kinetic energy.

Significant heat transfer can occur inadvertently during the heating/cooling
