TinMan's "Over Faraday HV HHO production"

Titanium ... My friend Rick did a test with Medical grade 1/8th X 9 inch titanium rods. Tap water, 35 volts, 1.75 amps for 1/2 hour.

Doesn't look good as one rod severely pitted after just the one run. He notes that home ionizers use Platinum coated Titanium.

Thats no good..


What about graphite , carbon, ferrite,  quarts or other conductive minerals ?

Just a hasty pic of my setup, 15 volts, first run, tap water, a small leak, no gas... happy!

Edit: Not unexpected ... TDS is 021  (Total Disolved Solids)

Lead is an interesting anode. It initially makes no oxygen as it forms a layer of oxide. This oxide is special as it conducts unlike other oxides and only forms a thin adhesive layer. Eventually oxygen  begins bubbling. The lead seems to last for ever, unlike stainless which often oxidises under heavy currents forming a  brown liquid probably full of toxic Cr 6+.
I can't remember the exact conditions but I managed to make ozone using lead electrodes in sodium carbonate solution with 20 or so volts. It came as quite a shock to smell the distinctive smell of ozone as at the time I did not know that ozone can be made by electrolysis of water.

That is a most interesting observation.  It is possible to generate
Ozone by electrolysis of certain salts but this (Sodium Carbonate)
is one I hadn't heard of.  Perhaps it is possible with Sodium
Bi-Carbonate (Baking Soda) as well.  Certainly worth a try.

It is possible that the Lead Dioxide electrode is a necessity and
that it functions as a catalyst for the generation of Ozone.
