DIY - Stable Redox Molecules

Hi broli,
Please DO NOT use stainless steel for your electrodes!  Stainless steel has chrome in it.  If you use it as an electrode hexavalent chromium will be released into the water.  Hexavalent chromium is a poison!  Try this simple test.  Put your electrodes into a weak saline solution.  Run some current through them for a while.  The water will start to turn a pale yellow.  This is the chromium in the water.  Please do some research on this and consider using platinum electrodes like charly2 is using.  I worked in a plating shop for several years where they did a lot of chrome plating.  Hexavalent chromium can seriously damage your health.  Please do not ignore this suggestion.
Sincerely and respectfully,
Carroll

Sometimes ignorance can indeed kill, chemistry is not my thing thanks. However platinum is way out of the budget for me to be honest, but I still have titanium and graphite. Surely the latter should be pretty non reactive and the only bad by product would be chlorine gas. Opinion on this?

Hi broli,
I think charly2 got his electrodes from ebay for a fairly reasonable price.  If I remember right they were titanium coated with platinum.  I am not a chemist either, I was an electrician working on the plating shop equipment.  Someone posted earlier that titanium was also a poison.  But when I did some research on that I found that titanium is used in almost all hip and knee artificial joints because it is considered to be totally inert in the human body.  I know we used a lot of titanium bolts and nuts in the plating shop because it was so resistant to corrosion.  I don't really know if that makes it safe to use as an electrode in something you plan to drink.  As far as the graphite I do know the original Asea water had a slight swimming pool taste when I tried a couple of bottles.  So I guess there was a little chlorine in it.  I am sure charly2 can answer all these questions much better than I can.  I just wanted to make sure you knew that stainless was not a safe material to use.

Here's another intresting thing I came across during some research into this:

Referring it to as "invisible electrolysis".

Thanks for the instruction. However most of the things I'm planning will be quite different I guess. I'm going to follow the high frequency flip flop method of this patent:

I think the flip flopping has the same function as your stirring, that is to have a continuously agitated solution. Also I'm going to be using mineral water as they do in the patent, they seem to imply that the elusive generated H⁻ ion which would be otherwise short lived would attach itself to these minerals to extend its life span. That's why they also suggest to throw in a rock in the solution. Anyway my biggest advantage is that I also have ordered this ORP meter:

So I can have a very good quantitative means of measuring how effective any parameter change will be.

Finally I'm probably going to use stainless steel for the electrodes.

I have being tempted to start building it, I am ok with my  electrolyzer so perhaps in a near future i will do it, I only need the  electronic part.

I have to agree with Carroll abut the Hexavalent  Chromium, some people say there is not scientific proof about its production  during electrolysis, I would play safe in this case. Please see this video and  take your conclusions:  www.youtube.com/watch?v=55_j21tCN_k&feature=results_main&playnext=1&list=PL0544F7A82D781657 

There is a nice thread in the EF posted by Jetijs you must have seen  it (Living vs dead water), he uses stainless steel and a filter membrane between  both plates, at the end of the process he gets alkaline water in one end and  acid water in the other. The alkaline water he gets is clear, and the acid water  is yellow this one is supposed to contain some amounts of chromium and is not  used, but it is just a thin permeable membrane the one that prevents a mix (and the electric charge), perhaps it is safe,  I don't  know. He has reported excellent results. 

Any IMHO if I build one of  those alkaline machine or any other similar machine one day I would use platinum coated plates. Second option for me but I have never tested is graphite.
The price of the electodes I am using is $35 each in ebay.

Do you know what kind of rock  is recommended?, I could not find information abou it. I guess it must add some minerals to the solution and help the  chemical process to produce different  species.
