Stainless mesh idea

[kipper]

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.
