DIY - Stable Redox Molecules

[charly2]

Now I understand what happened on the PPM readings, I took the readings at different temperature, enough to have wrong data.

I made another batch and at 33°F before start the electrolysis the solution was 1140PPM after 2.5HRS and same temperature was 1330PPM.
This is an increase of 190PPM. This make sense to me; new ions are created and conductivity increase.

Perhaps this could be used at home to test the solution stability after days, weeks or months. If ions re-join after determined time the conductivity will reduce so PPMs will reduce too.
Definitely this is not finished yet.

Day after day I noticed the taste is changing (I'm not dinking it yet), the first day it taste like a little strong pool water and fresh, but after days the taste is not the same, is more like bitter but not too much.
The TDS meter shows also a decrease in PPM. So, looks like it is reversing or degrading to something else. Not sure really.

Something similar happens when we produce ionic silver, after time molecules/ions join to each others until precipitate to the bottom, and the TDS shows a lower reading after hours and days latter.

I've thinking about it, what if after the ions creation time, I start to reduce the current (and volts by consequence) in a relative long process until reach almost cero amps?.
This only to avoid an abrupt current interruption, and let the molecules enough time to stabilize slowly.

Carroll (and everyone), perhaps you can suggest me a circuit to control the current from let's say 1 to 0 amps. At first a PWM came to my mind but it's output is allways the same current but pulsed at determined length to get an averaged current. My idea is to decrease the current in a smooth way.

Is there any other different way to do it?

All ideas (and crazy ideas) are welcome.

Hi Charly,

Does the conductivity of the solution stay the same throughout the process?  If adjusting the voltage to control the current is not a problem I am sure we can come up with an automated way to do that.  I am in the middle of adding a bathroom to our basement so let me think about it some and get back to you.  If anyone else has any ideas feel free to jump and help out.

On another thought do you think what you have is a solution of the redox molecules we want and they just aren't stable.  I tried making something similar by bubbling HHO gas through distilled water.  It also changed after a few days so I just dumped it and made fresh every couple of days.  Do you think this is an option for what you are making?  Or do you think being unstable might be detrimental to our health in some way?

PS Just a quick idea.  If you connect a large capacitor across the output of the PWM then it will average the pulses into a lower voltage and current.  Since the load stays the same as the pulses get shorter the voltage on the cap will gradually get lower.  We just need a way to automatically change the pulses.

Hi Carroll,
The conductivity is not the same all the time, when the process starts the conductivity starts to increase so current too (i.e. from 1.0 to 1.2 amp) until ion production gradually decrease and conductivity stays constant. But i guess this small increase in conductivity should not be a problem, we could consider it constant for practical purposes.

About the redox molecules I think they are what they should be, not sure about concentration or the % of each molecule or if there are all the 16 molecules claimed in the patent.
But my brother's pal (his dog) is still alive and alert during almost all day and night, so that is my only proof that is working (taking the same water from the same bottle after 2 weeks).

I have not tried the distilled water bubbled with HHO, but there should be good for our health, but use two or three bubblers before the distilled water to avoid contamination from your cell.
Water is oxidized at the anode and the reaction is: 2H2O  -->  O2 + 4H+ + 4e-
Water is reduced at the cathode and the reaction is: 4H2O + 4e-  -->  2H2 + 4OH-
the final products of water electrolysis are a small part of the asea water.

Not sure if will be detrimental to our health, but there is a possibility.
I'm a mechanical engineer and not an expert on chemical reactions, so involvement from people with better undersanding on chemistry would be really helpful.

And Carroll you are right a big capacitor will fix the PWM waves to make them almost flat, and much better if automatically change the pulses.

Sounds like you need a constant current source.
