The Coffee Pot view of a cell 4"x3"x2"
36VDC at 12 amps

Reading back through these post might explain the spark. But I have had sparks pop a cell. Just depends on the timing and the type of spark.

"Hit" your cell with ?
 I don't use 12 VDC  it does not work for me.
Try 36 volts with KOH , add milligrams at a time and wire your plates like this +nnn-nnn+ n = neutral = no connection

Also grind your plates in the vertical  to make them as rough as you can.
Horizontal seem to make the bubbles stick longer.

The Little HHO Cell .  I thank "pese" for showing me this type of design.
I will improve it as I go. Also I have been working with a person that is now running a car on this type of cell. The install was done today.

This is what I call a straight cell ie no pulse at 36VDC.
All Nitronic 50 stainless steel .(316L will work fine) This one has 14 Neutral plates one negative plate at center and two positive plates one on each end.
Spacers are 1/8" Teflon
Plates are roughed up pretty good vertically  with 36 grit grinder

Attention builders. No Magnets, we want no magnets in the cell and we want no magnetized stainless.Demagnetized before entering a cell .
This has been trued and tested time and time again by many builders.
Anything magnetic will cause strange electromagnetic patterns between positive and negative plates.A sorta of blocking or deterrence on the natural pattern.


The NS-T Cell
Is 90 volts or so VDC
NS-T is built like a capacitor , voltage increase till it shorts
Pulsed
Coil is not reveled yet as this is a test for the Fuel Injector type cell.
But yes there is a coil involved alone with Pure Tungsten and Nitronic 50 SS
NS-T produces both oxyhydrogen  and parahydrogen.
NS-T produces more of both and is very complex. There is a newer version as well. This cell will develop the next step , The HHO  Injector.

Hello. A few years ago I was working on a similiar type of water anode cathode system but for electro coagulating of elements in water as my main business is in the water treatment sector. I am enclosing a photo of the system I made for testing purposes. The control panel was made by a friend of mine with certain particulars.

Each voltage pulse is sweeped from 0 to 6vdc then back to zero, then it reverses the polarity on the anode cathode and repeats. Reversing the polaroty inhibits elements from sticking to the anode/cathode. Each pulse sweep is done about once every 1/4 second.

The sweep of the voltage is done to oxydize elements in water such as iron, manganese, hydrogen sulfide, tannin, hardness, etc. Each ion has its own reaction voltage so sweeping the voltage covers them all. The by product of this is hydrogen bubbles.

My anode and cathode are made of titanium mesh sheeting which provides the lowest resistance possible in order to not waste the dc. The titanium surface was specially treated by the supplier according to my specs before shipping and has an estimated service life of 50 years at the voltage range discussed. Two sheets were simply rolled together with spacers in between to fit inside the filter housing.

The unit produces hydrogen bubbles which in itself is a sanitizer so we also get rid of bacteria. But the level of bubbles will be directly proportional to the level of mineral ions in the water. That is to say that the water conductivity will influence the amount of current passing from the anode to the cathode.

So if you use pure distilled water in the system, nothing will happen because there is no possible way for the electricity to conduct through the water. If you used sea water at 35,000 parts per million of mineral (or 3.5%), you will get so much bubbles and at a much lower voltage.

Reading that you are using 90vdc on your anode/cathode tells me that your water may be very low in salts and you need such high voltage to create the effect. If you added some table salt to the water, your system will probably short out given the level of voltage you are using.

I may be wrong here, but I just thought I would give you a run-down on how I use my system. I never thought about specifically producing hydrogen but I will take a poke at this using my titanium elements. I still have alot of sheeting left (very expensive) so I can do some testing when the time is available.

Lastly, when doing tests, I think you should change the water each time since once you apply the voltage, the water conductivity will get lower and lower and hence your applied voltage between the anode/cathode will be modified. You may need a pocket type condutivity meter to make sure your water is always the same, otherwise you may have trouble replicating your results.

I will build one using my titanium in a few configurations to do some testing.

Titanium Mesh Sheet
- B265 GR2 titanium
- with IrO2/Ta2O5/RuO2 coating
- Sheet Dimensions 9" x 32" and 18" x 32"
- Thickness 1.0 mm
- Openings 12.5 x 4.5 mm
- Fe:0.30% max
- C: 0.10% max.
- N: 0.05% max.
- H: 0.015% max.       
- O: 0.25% max.

I also noticed the sparks. I think what is happenning is since your system is making like a capacitor, when you cut the current during pulsing, your capacitor is discharging perpendicular, similiar to Tesla seeing these sparks when he cuts high voltage capacitor discharges abruptly. Or like the TPU guys are trying to do. I think that there may be a way to re-use that energy by using real capacitors to get connected to the elements, when you disconnect the current. Alot of these guys here know more about that but there may be a way of getting close to OU with this if there is a way to grab back the energy dissipated in that spark. At least to raise the production to energy ratio. Maybe use the hydrogen to run a generator to produce the dc to make the hydrogen, etc.

Just last week I was doing some tests on an RV set-up running a 460 volts 3 ph electric motor on 120VAC that I was suppling via a 2400 watts inverter runnning off a 12V battery. Without thinking I unplugged the motor from the inverter while the motor was still running. The invertor just fried because the caps discharged back into it. Those discharges are pretty strong stuff.

As for the electrolyte you are using, what is the mixture required or is this open to the type of cell?

Neutral plate cell progressions .
Now pulsing ,soon to have videos on 3 times HHO output than in the past with this Cell.

Thermal imaging system added on pic 2

Hey Bro
The engine is sounding like she loves the HHO you are giving her.
From the video , are you using the bubbler as a overflow as well?
I will look around for some valves on this side of the world. If you can not find
I will look into shipping and such.

Also let me know how the speed controller works out when you get it.




Just Build It
