I read about venting the tubes on one of the threads yesterday by I think it was h2o but I don't remember now. Anyway, today I vented one of my tube sets to try this theory out. What I learned was meant by venting the tubes is to add a 1/4" slot in the upper outside tube about 1.5" in length depending on the length of the tube. For long tubes, it was supposed to be 1.5" and for shorter tubes somewhat shorter but no length of the slot was given for shorter tubes. I vented my 4" test tube 1.5" with a 1/4" wide slot. There was a real difference. Like the thread said, my tube could breath. I noticed first off that many larger bubbles were now comming off the tube set. My gap is 1.5 mm and before I vented the outer tube, my bubbles were very small. My water used to cloud up almost immediately, and now it stays pretty clear.
I haven't tested my amps yet but I am working off 12.2 vdc directly off a variac. I have no diodes yet and no pwm but there is an appreciable difference in the quality of the bubbles released. Thanks for sharing the venting scenario with us.

I didn't run the cell long enough. It clouds up also.

lol
the reason i put slots in my tubes was because i was producing hydroxy so fast it was not exiting the tube fast enough, a tube without slots is what i refer to as a tube thats choking, if it doesn't have slots and its not choking then enough gas isn't being produced. you can tell if a tube is choking by looking at it produce.
if enough gas is produced you will see the gas choke up, the slots prevent this, also helping to keep the water cooler longer. You usually get this effect when you are running at higher amps.
h20 is working on some sorta fluted tubing, not sure what he's up to?

Thanks for you reply to my post. Is there a formula you would recommend for determining the slot size? I have small cells and my surface area will be diminished by the large slot. Right now my slot size is 1/4" X 1.5".

Here is a pic of the single tube set test cell operating with the slot. The gap is 1.5 mm and the cell is operating at 12.2 vdc.

Oh, no circuit and/or chokes are being used in the pic. I still need to make my chokes and my IonizationX circuit.

Wow, thats a big slot!
nice pic!

Thanks Steve. Yes, I got a little carried away with the slot. Iit's 1/4" X 1.5" and the outer tube is only 4.5" long, so it's pretty big for the tube set.
-
how many tubes do you have with slots?
-
Just one outer tube on my test cell with just one tube set.
I am starting small, because I haven't decided how I want to build my base plate yet and/or how I want to tie all my tube sets together.

My vented 4.5" test cell is really putting out the gas at 12.2 vdc and 2 amps. I'm not using any chokes and/or pwm yet. I need to upgrade my Lawton circuit to a more improved version.
