I think you are right - the wetted area is what counts, and a shape
similar to a "W" gets the most wetted area in the smallest space. Of
course, you could fold it more times.
But why do you want to make so much? You only need a little if it's
done right.
A quart would take a long time to make at these currents.

When the production rate of ions is very slow, they have more
chance to disperse through normal diffusion, and have less tendency
to crowd and form particles. Diffusion is the effect you see when
you put a drop of ink in water. Pretty soon, the water is a uniform
shade. The ions do the same thing.
With a long brew time, the natural changes in room temperature set
up slow convection currents. These also help disperse the ions.
I believe Ken or Robert mentioned this some time ago.

How are you going to verify your results and tell when you are going
in the right direction? Without some kind of test, you are working
in the dark and just wasting your time.
The salt test is cheap and never goes out of calibration. There are
only two indications that are important:
A pale blue dispersion indicates ions are present, but at low
concentration. From what I can gather, the ppm may be around 10 or
so. This is typical of the results you get running at high current
density. This seems to work well on bacteria.
When you see white clouds growing from the bottom with wisps going
off in different directions, the concentration is quite good. I
estimate the ppm to be a bit less than 20 on my system. This seems
to work well on viruses.
Once you try this you will see how easy it is to tell good from bad.

Please put a resistor in series. Whether you are using a wall
transformer or batteries. Short circuits are such a bad idea.
If that is all you need, then go for it. But unless you are able to
test the result, you really don't have any idea what is happening.
You will end up asking everyone what went wrong. They won't be able
to help you, since they will not understand your process. I would
not respond to such ill-formed questions. Let some else do it.
I considered using a wall transformer with the simple cs generator.
The problem is they are not designed to run at very low current and
may produce a much higher voltage than stated on the case. I have
some that are wildly wrong, and each one is different.
This makes it difficult to standardize the series resistance needed
for the generator. People would have to measure the output voltage
of their transformer and calculate the resistor.
This would lead to all kinds of mistakes. People would do the
calculation wrong. They would pick the wrong value resistor. They
would not be able to tell there was an error.
The cs would be very weak, or there would be a lot of black sludge.
The same problems with the Hanna PWT would come up. Everybody would
get a different answer. Nobody would believe the process works.
I could add a load resistor on the output of the transformer to try
to guarantee the output voltage, but it is difficult to know what
load current is required. The load resistor might be different for
each wall transformer. The resistor might get hot and require a heat
sink. Where are you going to put it?
I could specify using a small bulb, but it would have to be 12V
There are no 9V bulbs as far as I know. Again, it may get hot, how
are you going to mount it, and how do you change it if it burns out
or breaks? What do you do with the broken pieces? Things like this
are extremely difficult to handle in a simple description.
There are simply too many unknowns with a wall transformer.
It would work fine for people who know what they are doing, but that
was not the purpose for the simple cs generator.
After considering all these things, I decided the best was to use an
ordinary 9V battery and standardize on a 33k resistor. The color
bands are easily identified so there should be minimum chance for
error. The battery will last at least as long as it would in a smoke
detector.
The design is not optimum, but it will work quite well if the dw is
in the right range. This is not a handicap. Every cs generator has
the same limitation.
The cs will gradually get weaker as the battery reaches the end of
it's life, but the salt test will quickly show this long before it
occurs. If people do a salt test after each run, they will have a
very good idea what to expect by the time the battery is ready to
die.
It is not difficult to solder the three connections. I learned how
to solder when I was 8. My mother is 84 and it took her five
minutes. She did a fine job.
If soldering is a problem for some people, just find the nearest
teenager who has a soldering iron. It will take him two minutes or
less, and he will be happy to do it for nothing.
Especially if the cs helps get rid of his cold sores. No teenage
girl likes to kiss a guy with cold sores. I know - I was a teenage
boy long ago:)

Thanks for your questions:)
