Sorry to pick you out Steve, I never imagined someone would go over
500VDC for a 1-2 volt process. Constant current, as I said many times,
IS NOT A MAGIC BULLET! Limited CURRENT DENSITY is an essential
process refinement! The HVAC process you refer to, which is rather dumb
and even more dangerous, has been discussed before and found to be
of very questionable merit. I have many years of HV experience but have
never tried the process, based the low impedance level involved and my
electroplating experience. Absolutely no need for HV - has shades of 1930
when they searched for "magic" processes to produce Cs. Sintering, as
one producer describes his unit!
Search the archives and you will find one researcher who has found it to
contain many crystals of silver and oddball changes in pH. He has a web
site with photos, if you wish to see what you are making. I for one would
not let it pass by my lips! Pee YES, HV Cs NO. <he he>

Fred and list,
In my case, I take exception to your statement below. I really do!! I
built a constant current generator which produces exactly the same constant
current from the starting instant to the end. At the moment, it is set for
1.67 ma., which produces approximately 5 PPM/hour. The starting voltage
can be over 500 volts, so it can handle very low conductivity distilled
water with no added electrolyte. The batch I brewed tonight started out at
about 180 volts and ended after two hours at around 15 volts, all at 1.67 ma.
I still don't know the optimum current to set my HVDC generator for. Is
there a lower threshold of current (x microamps?) where the energy level is
too low to "knock off" silver atoms from the electrode?
