not getting any pressure

[zetan]

Howdy,

This is my first attempt. I'm not getting enough HHO outlet pressure to get bubbles. Please review below and let me know what you think?

12" long, 4" diameter sched 40 black PVC pipe, two end caps attached with silicon sealant.

The simplest plate design,
(3) 3" x 6" 316 stainless plates
+ N -

1.1cm spacing between plates, mostly due to use of 1/4" nuts and lock washers to makes connections solid. Rubber bushings for the not-connected
holes.

1/4" stainless bolts, washers, lock washers, wingnuts.

1/4" stainless battery terminals connected to the plates by
a stainless L-shape bus bar strip (no copper, solder in the container).

I realize electrolysis starts at 1.24 volts, so I' thinking the best
configuration for a 12v system would be 10 sets of plates in parallel.
Is that correct?

I just found Metal Supermarkets for materials & cutting.

Up to 3 teaspoons of KOH now.
Luckily I use KOH for making biodiesel.
Does KOH + electrolysis have a byproduct gas?

The unit does make quite a bit of bubbles when hooked directly
to my 100AH Werker deep cycle, or my 2 RV deep cycle wet cells.
I get enough current flow to notice the wire terminals get warm at the battery. I have not been able to measure temp, amp, or LPM just yet - waiting until I get some positive pressure.

I blew up my 555 based PWM a while ago, need to replace the MOSFET and get a heat sink!

I run the hose outlet on top to a small glass jar of water. Tried placing the jar above or below the HHO generator.

While I can Hear gas being created in the hose, I cannot get enough pressure to make bubbles out the tube.

I'm hoping to improve the mileage of my 1984 GMC Rally Van 6.2L diesel.
Gets 15mpg towing & 20mpg freeway. I also make biodiesel and this seemed like a good alternative fuels project run with.

Why reinvent the wheel on your first shot, there's lots of great dry cells to copy from this board for free

I wanted to get the simple proof of concept down before getting complex.
I suspect my cell spacing is far to large to get any useful volume.

Your cell spacing and number of cells is what is killing you.

Drop down to five neutrals in each set, aim for 2v per gap, and bring your gap down to something in the order of 2/16".

I had a leak in my cap. I am now getting bubbles glugging out the bubbler!

Time to increase the volume by improving the cell spacing.
Thanks for your input.

You're more than welcome.

If you get some time, pop over to my website http://www.hhoknowhow.info/ and read the article on Cell Voltage (http://www.hhoknowhow.info/node/3), it will give you some good insight into what works well and why.

KOH as an electrolyte has no byproducts, it is a true catalyst in that it doesn't take part in the reaction itself and is not consumed by electrolysis. However, you should be aware that KOH can escape with the HHO inside water vapour. If you see a white mist coming from your setup, this is the KOH. You don't want to let that anywhere near any aluminium as it will eat it.
