i chose this number of plates based on the fact that each neutral plate forms another cell so with 3 between each anode & cathode there is like 4 cells formed in series which gives just over 3volts each,
checked with voltmeter and this is the case - measured approx. 3v between every plate.

apparently anything over 2.5 or so volts just wastes power on creating heat, not gas.

that is the logic that i used.

also didn't use bolts or rods to hold plates - just those pieces of acrylic on each side - ends of plates are molded into the plastic to minimise leakage of current around the edges thru electrolyte.

yeah, thats the one (coil thinger), wouldnt have the foggiest how to make one...

maybe send them a friendly email and compare notes or something, i think the coil system is the way to go

Anybody from adelaide, - do u know this bloke or had anything to do with the system he is selling?

You couldn't solder contacts as they would corrode.
rubber is likely to disintegrate.
I love the U-tube video's

sorry i haven't been posting any new results, but haven't been doing many miles lately. numbers are still around the 30% mark on average.
have also been trying to figure out where is best timing setting.
Factory setting for this motor is 6* adv. base timing and i had been running around 10 or 12 since putting hho on, but info that i found lately suggests that there is more to be gained by retarding base timing with hydrogen present,
One bloke even had his advance mechanisms disabled - and running at 0*
(VC Commodore -but he was using compressed hydrogen from cyls in the boot and no extra oxygen)
So at present i have dropped it back to 4* BTDC and will see what difference that makes.
Logic is that hydrogen speeds up the burn rate of the main fuel therefore no need to fire it early.
This is why i think the exhaust note changes, - burn is complete before exhaust valve opens so no real explosion into exhaust port.

Here is another you tube link to a bloke calling himself Zero Fossil Fuels. He has very good explanations of his constructions and has nearly 50 different video up to about 8 minutes each. I thought that this particular link maybe beneficial to Garthr's R & D. This link is number 29 of his series. He seems to be developing his ideas with donations from interested people and sharing his results with all. I found his video particularly interesting. For anyone else who may be interested, here is the link.

Sincere regards,

Yes saw him the other day - found particularly interesting and probably copied some of the features that he uses

Tried adding a PWM (pulse width modulator) today to 1 of my cells but was a bit of a failure, didn't seem to make much difference to output of cell and got very hot very quickly.

It was a DC motor controller kit from jaycar so may not be the right type.
It has set frequency and just alters pulse width. From what i can gather we probably need something that can also adjust frequency to really make a difference to gas production.

Now i'm thinking that multi-cell setup is probably way to go next.

here is a handy milage calculator sheet that i use, (excel based).
in case anyone is interested

U made quite a fast progress, Garthr..........

Maybe one day we can control gas production according to engine speed using switching power supply method......thus save energy too

yes i notice 1 system actually switch their cell off anytime throttle is closed, apparently dyno testing found that this was the only time that system draws more power than was to be gained, - most gain was at wide open throttle

Perhaps an electronics guru can link a circuit to read the Thottle Position Sensor for power on and off. I have recently purchased a book at Jaycar called Electronics De-mystified for about $40.00. it is very helpful in understanding electronics and calculating power, resistance and current etc. I am positive a simple circuit could be used to assist your R&D Garthr.

sincere regards,

I was just thinking of a micro-switch or such, mounted on throttle linkage near carby & wired in line with sw on the dash that controls the relay.

Hmmm, thats a good idea Garth, I think I'll put one of those on mine . ( runs off to the shed and rumages through some old milo tins full of lots of useless stuff , unless your an inventer that is. Give's up way to soon after not finding a micro switch and decides to just play on his 360 deg swing for a while http://au.youtube.com/watch?v=82rCAs3drfk hoping to get a brain storm.) ( later on that afternoon ) Hey I just though of something, I'll try it and get back to ya Garth. cya.

This is very interesting, please keep posting back results from your tests

Am I game to try this on the almost brand new $50k terry ghia????
nahhh
I will play with the ef 356000klm beast first

constructed another cell today that produces really well. here is a pic of the element. Made from 3/16 stainless cable threaded through holes drilled in some 40mm pvc, about 7 turns each in a double helix formation.
just made a couple of lugs out of 0.6mm stainless and crimped on top ends to bolt through housing.
Pvc is about 150 long.
Housing is identical to one that i already posted up before.

Um - do you actually know what a micro-switch is?

BTW - i really like your swing.

update.
Checked mileage today after changing some things and it has dropped way off, looks like i will have to backtrack a bit to where it works best.

After testing different timing settings, have settled on about 10* btdc.
retarding was a bad idea, (apparently that is only required if running purely on hydrogen.)

Other changes that occurred were removal of coffee jar (lid was starting to disintegrate)
Which means only gas input now is into intake tube prior to carby, & nothing into manifold, so i will have to address that.
