I had an idea to take 2 layers of fine stainless mesh and 2 layers of plastic mesh and roll them together into a bundle. Then I would slide the bundle into a tube (perforated maybe) and pump water continuosly through the tube. Then to form a proper cell there would be whatever number of tubes necessary for the given voltage applied.
This would be difficult to do especially for making electrical connections but would have a large amount of surface area for the electrolysis and the pump would keep the water moving, cool and also (hopefully) push out the HHO out.
Just an Idea I had while looking at some SS mesh the other day and I will likely try it at some point to see if it works or I am just half baked :-\
my design I'm working on has stainless steel circular plates with a fiberglass mesh ( window screen) in between.
the few plates I have assembled works okay.
Well before it gets blurted out there... Mesh idea... Place 2 tubes of SS mesh one inside the other about 2mm apart. at the top of the middle tube attach a small lenght of SS pipe. connect the gap between the 2 tubes (after the bottom of them has been secured to ensure it doesn't short) with a hose to pump water from the top... The water running between the 2 SS mesh tubes "should" act as a separator. have the middle tube as a vent for the O2 and the out side case as thin as possible to collect the H2 and have an outlet at the top of the cell... bottom of the cell can have a pump attached to re-circulate the water. wouldn't need a big pump, less than 5lpm i would think as this would ensure that there is always a "wall" of water the whole way down the tubes... the only percievable problems would be maybe an increase in needed voltage to accomadate for the increase in the gap... but you have also separated the H2 from the O2 meaning there is no need to alter any sensors on newer cars...
Just a thought.
Kipper-
I'm glad to hear someone else is experimenting with the SS screen. I have a 100' x 4' roll of 316L SS dedicated to electrolyzers for
supplementation of a 30hp diesel genset I'm in the process of building. It has 2 Zena alts. driven by serpentine belt, one is 12v-150A and the other is 24v-80A. The 12v alt is dedicated to a bank of 6 folded screen/plate electrolyzers (2v-25A each) and the 24v alt is for charging a 24v flooded nicad battery bank.
So far I have built only one of the electrolyzers, and am already seriously considering design changes.. I have however found out that you can silver solder multistrand copper wire to the screen, thereby eliminating some of the resistance encountered with SS bolts, rods, straps or what have you that penetrates the cell wall. The interface of copper/solder/screen is going to have to be protected from the electrolyte though, right up to and overlapping a bit onto the wire insulation... Can you recommend a product that possibly can stand up to a 15% KOH solution + heat? I'm thinking maybe black hi-temp RTV or something along that line.
Anyway, best of luck to you and please keep us updated on you progress/failures, as much may be learned from both.
test it if you want guys, but mesh is not very eff. in the production of hho. Many have done it, take a look at what has been done before and see if it meets your expectations.
Take D3's word for it Mesh is not a very good idea, I tried SS screen way back when I first started playing with HHO and it sucked ...here a list of things i tried that sucks for production of hho ..
Screen sucks really bad
Tubes alright but still sucks
Wire sucks really bad
Switch plate covers(wet cell),were alright but not great ..
Switch plate covers (dry cell) was better but still not great ..
The most efficient cell I have ever built is the Dry cell with 6"x6" plates ..or 8"x8" plates
Just my 2 cents on stuff I have tried
jdcmusicman
for efficientcy i am sure that per cm2 mesh would suck as the active surface area would be less... you would only use the mesh if you were looking at using porus style electrodes...
OK, I see that everyone is thinking of just one layer of screen for each pos or neg "plate"- I used several layers of screen folded over itself for each "plate", as the goal was to create more effective generating area for a given amount of space. I sat down and did the math based on wire circumference x total length in the X and Y direction x 19 (strands per inch). It worked out to be significantly more surface area than solid plate of the same overall size 8)
More surface area is great , but the more holes the more current leakage there is and therefore less electrical efficiency.The more holes the more heat is created..I'm just saying electrically its not efficient...
@musicman
OK, I'm feeling a little bewildered here- current leakage from where to where? Sorry- I know I hate explaining myself to others that just don't seem to get it, probably because I'm not a fast typist...
Current leakage is when the electric goes around the plate(mesh) thru the holes instead of going thru the steel , ...it takes the less resistive path .
I get it because I Have done built a cell like that about 2 yrs ago .....it causes excess heat , and electrically is just inefficient for the amount of gas and electric to make it .....Just build it , if you like it great ......I done the same thing man , people telling me this and that but I tried stuff for my self......No offense meant ...

Hey guys,
Little off topic but has anyone of you worked with "flat transformers" as given here:
http://www.coilws.com/Publications/FlatHCLV.pdf
http://www.flattransformer.com/FTT-Windings.htm
I am building custom AC to DC high current converter for HHO generation and bumped to the technology but could not find more info on the net :(
One more time sorry for the off topic question.
Any info will be highly appreciated.
thanks,
@musicman-
No offense taken my friend, and thank you for the insight... Now to figure out how to tell my wife that the big roll of EXPENSIVE SS screen was a bust... hmmmmm...
You may have better luck with it than I did ...
