notice you only need the >179 figure to get above the Debye temp. You can get
around that by alloying the Ni with Cu and even annealing.

I personally use both copper and gold in Ni to drop both the Debye temp and the
energy of vacancy formation. A rough rule of thumb is that adding a softer
lower melting point material to Ni or Pd is good. So far, I have to keep my
metals fcc.
Notice also that you can drop the energy of vacancy formation also by having
finer materials. If they are small enough (somewhere around <10nm) the becomes
little difference between the Ef for bulk and surface. (normally, the surface
Ef is lower than the bulk)
so.............. I say all that to let you know that you can have systems
that work below 179 C. My demo at NI week will be operating at 80C.

Subject: [Vo]:Defkalion/MFMP implications for electrolysis?
With the recent corresponding findings of both Defkalion and MFMP suggesting
the temperature needs to be >179C to initiate the reaction, I am wondering if
this may also have implications for electrolysis with nickel.
Obviously, it would be difficult to run electrolysis at a power level high
enough to heat the cathode to that temperature for very long (the water would
boil off). A pressurized electrolytic cell would seem to be an option.
Another option would be lateral cathode pulses of high power and relatively
brief duration to bring the cathode temp above >179C, but avoid boiling off the
water. The trouble with this method may come in if the nickel needs to remain
at >179C.
This also has me wondering about two other things.
1) Brillouin Energy's method of electrolysis would seem likely to elevate the
cathode temperature >179C. Could this be a factor in Godes' success?
2) Electrolytic plasma experiments with tungsten -- is the cathode temperature
a key element rather than the plasma?
Best regards,Jack
