New Choke Configuration. HV Water Dissassociation. (Low Power)

[Farrah Day]

The white substance can only be created from minerals in the water, so there are only a few things it could be.  Yes a lab test would be the obvious solution, but it might prove more costly than you think and exactly where would do this test for you?  Maybe a local Uni might be able to help?

Actually, if we assume that it is a compound of calcium then we might be able to test it ourselves. I'll delve a little more.

@passion1, I have treated all of my tubes the same way. The difference between the current set of tubes and the tubes that now seem to be primed is that I had been experimenting with the primed set for about 2 to 3 weeks with very High Voltage/Very Low Amperage circuits. Never getting any good production out of them. Them I let the sit around of 1 to 2 weeks while I experimented with a fairly new tube. Finally, when I decided to create the 4 tube prototype, I noticed the white coating on the tubes from the prior experiments that had been sitting around. So it seems that HV and them letting them dry may have something to do with priming. More careful research needs to be done to see if that is true. It would be nice to have a quick procedure that results in a good white coating for optimized performance. So that even if the white coating does wear out, it would be easy enough to switch over to a different circuit to re-coat the tubes. Also possibly a drop of some'thin-some'thin to accelerate crystal growth.
In washing the tubes, I washed them with Castile liquid soap and them soaked them in vinegar for about 2 weeks. Probably only need to soak for a few hours. Then let them throughly dry. Also wore rubber gloves whenever I had to handle the tubes so that no skin oils get on the surfaces. When I washed the outer tubes, I used a long nylon brush that was able to give inside of the outer tube a really good scrubbing.

@Farrah Day, Thanks for checking out my data. Your info on   the coating is very interesting. The coating seems to continue to surface as a key to OU HHO production. Unfortunately, I'm not good at chemistry myself. Yes, I'll do more experiments using pulsed vs straight DC on the primed tubes (that would be some interesting data). I'll have to find a good gas flow meter. Yes, it does not seem that acoustic resonance is not so  important. And, LC resonance and HV is not useful unless the cell has a coating so that it can hold on the HV and use it.

Hi Dogs,

Nice work on the circuit and tubes so far..


I have mentioned in another thread that maybe bottled mineral water could be the answer.

Some bottled mineral waters advertise that they are high in Calcium Carbonate. ( Hard water )

Here is some info from an aqaurium site   http://westerncichlids.com.au/what-is-water-hardness/

The simplest way to increase the hardness is to incorporate calcareous material (e.g. limestone, crushed marble, lime sand) into the d?cor or filter. This will slowly release calcium carbonate into the water. Pool salt, non-iodised salt, Rift Lake Salt additives (e.g. Seachem products) and some bottled hard mineral water (e.g. Evian) can also be added. Some aquarists even add a small percentage of sea water to the aquarium (around 2%).



So maybe check the labels on your locally available bollted water and try conditioning with it.


I suppose after conditioning normal water would be OK.

My tubes started to develop the white coating after a few days while I've been playing around with straight dc experiments.  Not sure about the calcium oxide as some folks suspect though. Sure there is a good quantity of calcium in hard water areas here in the UK (I'm in one), but it's the oxide part that's niggling me.

G'day Farrah,

There is a simple way of determining if it is a calcium deposit you are dealing with. The test is not all that reliable because it really only proves it in the negative but worth doing and it will cost nothing since I assume most households have vinegar.

Just soak one of your tubes in vinegar. If the deposit does NOT dissolve in vinegar it is not calcium. If it does, there is a good chance it is.

Hope this helps
