I saw some posts indicating the type of PD and who you purchase it
from is very important to success. Will the rigidity be maintained
through co deposition? As to lowering the cost would co-deposition
on a Pourous Stainless Steel tube still meet the criteria for
rigidity? It would still provide the cathode but also allow
variations for those wanting to disassociate the hydrogen through
the tubes membrane like a little reactor using a tungsten filament
inside. The best of Mills and Arata combined?

Someone correct me if I stick my keyboard in my mouth or my foot in
my keyboard or something like that.
Palladium fabrication quality is critical for Fleischmann type cells.
I don't know about purity; some impurities might enhance the effect,
some might suppress it, I'm sure a lot of work has been done on that.
However, with codeposition, the palladium lattice is "manufactured"
inside the cell. I imagine that deposition conditions may affect the
"quality," but codeposition seems to create a fractal surface, it's a
very different approach.
Substrate for codeposition appears to matter very much. Gold seems to
be the best? For kit cells we only need a little cathode, it may be a
piece or coil of gold wire, or perhaps gold foil? Wires and foils can
be very low weight, especially with gold. I'd been thinking we'd use
platinum, but silver is also a possibility, I think.
Now, something is hinted at that has been rattling around my brain.
If a cell is sealed, and we run electrolysis in it, it's dangerous,.
But that isn't so true if the cell is small, because the whole
apparatus could be contained inside a box that could contain the
pieces safely if it blows. So ... what happens if we electrolyze
heavy water in a closed cell? The pressure of deuterium gas and
oxygen would build up. How much? What does oxygen do in this
environment? If the oxygen could be scavenged out (how?), could the
deuterium pressure go high enough to run an Arata cell? But this gets hairy.
How about a nice, simple codep cell, with materials known to work? To start.
I do have a serious question about sealed vs. open. If we aren't
worried about calorimetry, we could recombine very simply to keep the
pressure down. Sealed is nice for lots of reasons, including possible
helium analysis later. Sealed is a factory cell, ready to go, just
add current and see what happens.
All ideas are very welcome at this point. Later, those of us who want
to go ahead and *actually make something* will have to make choices.
Individuals and small groups may want to pursue various wild ideas,
but the central project should be very solid. If possible, there
should be some general agreement from those with experience that the
cells will work as designed, before they are ever built, which means
that variations from what is known to work shouldn't be ones expected
to quash the effect. (I don't think that a cell being small should
quench it, for example, just lower cost and be safer.) Once we have a
solid experiment, then all kinds of variations become possible.
