assistance needed: comprehensive design suggestions on HOD system.

[Aveon Blitz]

I am attempting to design an easily manufacturability and installable system that will increase a vehicle's efficiency by at least 30%, 60-100% would be much better.
I would like suggestions on the design, I do plan on the system to be a brute force system, using stainless steel plates, or another plausible material you might suggest. I have been messing around with plate design and configuration but have never really exceeded .5LPM with any of my systems. It seems that many here have made much more progress with this technology than I have. While my goal is 30% I don’t know what that would need in terms of LPM, a suggestion there would be helpful.
I would like to have a system that draws under 20A and does not use pulsing if possible, just to reduce complication. The simpler the system the more economic it would be to produce.
Any suggestions would be helpful and I would be grateful for your input.

The Linnard Griffin system seems very interesting, but would not fit my needs because of the maintenance required. I will be looking in on the progress made on it though.

If you are satisfied with the Brute Force then for best efficiency I suggest using multiple 6 times  2Vdc cells , chemically isolated from each other and electrically connected in series. I don't know if this setup requires conditioning of your Electrodes whichever type you want to use.This will give you the least heat and best efficiency using 12Vdc.This way you wont need  PWM to lower your Current.
The Drawback its larger and harder to construct and you have to devise a method to collect the gas from all 6 cells as well a method to refill all  of them mind you if they stay cool  there will not be too much evaporation.
Good Luck Someone can confirm or deny what I said go ahead its all yours.

hm, so you are saying that having cells in the same electrolyte bath is less productive than having them in separate? interesting, i will have to experiment with this. thank you for your imput.

Hi Aveon Blitz
This is a fact. Let me give you an example: If the 12vdc Automotive battery were all one cavity and chemically connected you would get lots of amps but only 2 .xx Vdc. If you tried to charge it with 12 Volts,as you are applying  that to the Water Cell, you would boil the Battery. It would produce a lot of Hydrogen and oxygen but you would require a lot of amps that is going to waist in the form of heat.
The Watercell depending  what and how much chemicals (KOH) you use in, it charges up and holds its charge like a battery except delivering unusable low current. So it behaves somewhat like a Battery.

If you want an fairly easy build and one that is electrically efficient and
can run well for hrs without any real heat issues ,build a 16 plate 6x6
4n3 configuration drycell..I have one on my car it works well. I get 1 1/2 LPM
on about 22-25 amps....Just get ya stainless steel plates ,pick you up some
1/2 cutting boards from walmart,get some 1/16" neoprene rubber for gasket
materials off ebay,some nuts and bolts and just build it...You have to build a water
reservoir and and a bubbler also ..I built my whole system on my car for under
100 dollars.Its paying off slowly , getting me an extra 5-7 mpg ....
It will take about 4-6 hrs to build ,preparing the plates, cutting gaskets, drilling holes ect..
But from experience its worth it , beats the crap out of any wet cell setup...
I have been there and done that , and will never build another wet cell setup ,
they have way to much heat issues,and are not all that electrically efficient..
Drycell is the way to go in my book..and the other good thing about them is
you can squeeze them in alot tighter spaces if room is an issue ...and they are easily expandable
just add more plates more gaskets longer bolts and good to go ..

Hope this helps ya , have a nice day
