Is it possible to use carbon plates as electrode? Also, can a small amount of carbon dust be added to elyte solution to increase conductivity? Trying to think out of the KOH filled 316L box.

I have seen others use carbon plates; they were getting real good results. However they tend to be very expensive. If you have some to give me, I'll try them out for you. :D

As for the carbon dust, I have not heard of anybody trying this. It is an interesting idea.

I have tried carbon rods - check out my vids

Well, I just ran a simple test:

using about 1/4 cup of distilled water I measured the resistance >1 M
I then added about 1/4 tsp of ash from my BBQ ~150 K
then starting with clean water added a few grains of NaOH ~80 K

Conclusion: It might work, but probably not as good as NaOH or KOH.

Wouldn't the carbon in the water be a recipe for carbon monoxide?

I know some peeps swear by graphite plates.
