Wayne,
I think there is an attempt, for safety, to limit the voltages to under 40 volts DC for people who
don't have strong backgrounds in working with electricity. This, I believe, is because of a rule of
thumb that voltages below 40 volts generally don't give life threatening shocks to people who are
using them in normal ways...
I also remember some people indicating that 30 volts DC caused less crud to build up on the
electrodes when making CS in simple cells. I don't know for a fact that this is so, having never
done any experiments in this regard. Perhaps someone else with experience can respond to this.
I think the idea of higher voltages is interesting, but people should be aware of how to work with
the high voltages and be aware of their own limitations if experimenting in this area.
Several people have had success with the microwave power supply CS makers which seems to violate
several rules we use for low voltage CS making, such as the rule of 1 to 1.5 ma per square inch of
electrode area. I did some calculations, of which I have no idea if they are valid or not, that
seem to show that in a cell of this type with the electrode spacing used, without stirring, that the
ions released will not reach the other electrode within the 10 minute time often cited for brewing
time. This may be why this type of cell is able to make the high ppms without stirring, and with
high current densities, etc.
The idea of using transformers backwards is a great idea, within reason. Some may not be rated for
the resultant high voltages. Using a transformer with two primary windings, one for the primary and
one for the secondary, for lower current applications, will give an isolation transformer.
If you use the neon sign transformers, you will need to find some high voltage diodes to rectify the
currents. I have tried making colloidal gold with the NSTs but it takes a long time. I wonder if
DC would have been better.

I wonder why no one used 6 each of the 9 Volt Batteries?
My Telephone line generator works better and faster than the 27
Volt unit that I first used.
If one used 6 of the 9 Volt Batteries, he would have the same speed
that I get with the
52 or 54 Volt Telephone Line Generator.
When I first started making CS, I continued connecting batteries
until I had 75 Volt DC.
There is likely no limit to how batteries can be connected. One
could even make an adaptor to use the car battery. They do not even
have to be the same. 6 Volt, 9 Volt, 12 Volt, and 24 Volt could all
be connected.
Most people do not realize that transformers can be connected
backwards whereas the secondary is connected to line voltage and the
normal primary is used as the secondary.
I have some neon sign transformers I have been saving for
years. Likely they would produce a nice source of high voltage DC if
I had other compatible components.
The highest DC voltage I was ever shocked by was 650 VDC. This is an
attention getter for sure.
Not sure how it happened. I don't remember that. But I remember how
it felt and the fact that it removed me from the work bench by
several feet. That, plus the one hit by lightening remain the
highlights of electrical shock. I could taste blood after the
lightening hit. My face was numb for several hours exactly like it
is when you go to the dentist. Never again do I talk on phones, in
a metal building, during a lightening storm.
Years later when I serviced the high voltage test equipment in a
battery manufacturing plant, I had learned a bit more about
safety. I stood on rubber mats, kept one hand behind me, used high
voltage probes, and disconnected power before I changed meter test points.
Some new people are in a bit of a hurry deciding what to buy or what to
build.
As you pointed out, the 3 NINE system will get someone started and
after they learn and understand the process, they will find free
junk that will make different types of CS generators.
All they have to do is visit a 20 to 50 year old shop like mine and
most people will give them a 5 gallon bucket full of transformers,
power supplies, and other components.
Most of the junk I save is to give to friends who know what to do with it.
Today, I honestly think there is a technician of some sort on every
block that is anxious to help beginners.
