Do you recall whether or not P&F made cracks in their material? I have been
assuming that the high pressure of the hydrogen due to electrolysis would cause
the nickel - copper material to generate internal dislocations as the hydrogen
forces its way in. I understand that hydrogen makes metals brittle by this
process.
Yes, I understand what Ed was speaking of and plan to subject new test pieces
to stresses such as torch heating and water quenching. I also will try
mechanical stresses and scratches as with a grinder and hammer, etc.
It takes time to generate confidence in a test system and test samples so I
need to work with this one for a while before I abandon it. Today I am seeing
clearly positive results which must be verified or disproved. I must use my
calibration sample to determine if the results are real.
The sample I am testing has been loading with hydrogen for around 36 hours.
Keep your fingers crossed.

You have read what Ed Storms theories about how cracks are the source of LENR
activity, but you haven’t applied this lessen to your experiments.
In order to produce crack, the area were nuclear active sites are formed, the
metal used in the cathode needs to be pre-stressed enough to produce these
surface cracks before the metal is used in your experiment. The way to do this
to this metal is by subjecting it to mechanically created metal fatigue.
Fatigue is the progressive and localized structural damage that occurs when a
material is subjected to cyclic loading.
Fatigue occurs when a material is subjected to repeated loading and unloading.
If the loads are above a certain threshold, microscopic cracks will begin to
form at the surface. Eventually a crack will reach a critical size were LENR
activity will begin.
The easiest way to fatigue metal for the LENR hobbyist is to subject a wire to
repeated torsional stress.
If you have a microscope available, verify that the surface of the cathode you
plan to use in your experiments show cracks on its surface.

The temperature the bath reaches depends upon the input power you deliver to
the system as well as any excess heat that may be generated by the electrodes
and the ability of your system to trap heat. If you are delivering 12 watts to
your device and getting a temperature rise of 60 F from ambient then you must
have relatively low heat loss unless of course you are seeing lots of heat
being generated.
The maximum temperature seen thus far with my present experimental setup was
130 F with an ambient of 74 F. I had 28.7 watts of drive at that time. I am
using a large electrolyte bath that is open to the air and one benefit is that
I can dissipate a large amount of power before my electrolyte reaches boiling.
This allows me to increase the current density significantly. It is currently
within the bounds of the successful level for the palladium deuterium systems.

It seems like from the experiments I've run that if you want heat, put enough
borax in so that it settles to the bottom. Then put your electrodes down into
the borax powder in the bottom. Eventually, the borax powder disappears
leaving yellowish nearly transparent crystals on the electrodes and in the
bottom of the cell. It is easy to get 120+F temps with an air temperature of
60F using 12V @ 1amp.

My anode is a motor brush so its surface area is larger than that of the

I have increased the current to 400 milliamps. With the active and
control beakers in series, the power supply is at 30 volts to drive that
current.

I was hoping to avoid the higher currents, which could mask any
anomalous heat being generated.

I had a lot of heat, whether it is "anomalous" or not, I don't know. I
think it is somehow resistance heating through the borax or chemistry with
creating boric acid. Just a speculation. I had heat >130F (I say it this
way because my thermometer was electroplated or something causing it to
register 20F too high. It read 158 or so at the max). To get more heat,
you need an anode with as much surface area as your nickel. I used 12V at
1 amp.

Has anybody been able to replicate Chuck Sites results? I
have not seen any claims to that yet.
