Just another thought after thinking about your 1000:1 recombination problem....  I'm assuming this is a 4 cycle type of motor.   If so, why not a combination 4 / 2 stroke setup.  The only modification I'm proposing would be a port in the lower cylinder wall to allow air in before the upstroke of exhaust.  Once the engine is up to operating temperature this may also aid in water removal during the exhaust stroke.  In order to keep atmospheric gases out during the intake phase, use a reed valve or some such device to only open when the vacuum is present.

One more note about H2 water engines....  The one idea that I've seen that seems to make sense (since the H2 / 02 is hard to manufacture fast enough) is one I read about that uses an electrolysis setup whereby the gases produced are an additive to the normal intake to the engine.  I believe one design (yes, the Ma'at or whatever, which is more complicated than needed, I think) uses a frequency applied to the electrodes.  The only reason I can see for this is to have an external input from the rpm of the engine to regulate the frequency, thus producing gas proportional to the need of the engine.  The claims in this case are mileage increases due to the H2 being incorporated into the burning process at a set percentage.  Yes, Ron, the Ma'at is stupid when it comes to electrolysis, DC is better.  I'm wondering though, if it isn't supposed to be used (the frequency) as a 'throttling' device, like a duty cycle on an electric motor speed controller....   

If this could be proven true, then water harmonics is probably the key to magnified production rates not possible with even a DC setup.  I would like to know how it goes with that.  I tend to go with the Tesla and Keely thinking in many of these things that harmonics or the 'right' frequency is a key to unlocking alot of things we aren't able to accomplish now.

Hear me out, then let me have it! OK
I too have toyed with frequency to disassociate water, but obviously not to the extent either of you have.
I too have tried to read Stan Meyer's patents and determined they are cryptic, but do not let me discourage you if you can crack the code.
Having said that, here is some of my conjecture based on a little research and a lot of thinking.
?? ? Observations
? ? ? ? ? ? 1. Freq of water is key but, there are more possible frequencies than water molecules
? ? ? ? ? ? 2. Current flows thru an Electrolyser by ionization, which does not seem to respond quickly to changes, 8 or 10 minutes is
? ? ? ? ? ? ? ? not uncommon. This puts trial and error way outside the limits of my patients :'(
? ? ? ? ? ? 3. Starting (or restarting) ionization requires much more energy than sustaining it, that is why a starter is required for a flourescent
? ? ? ? ? ? ? ? ?tube. The process must be re-started with every pulse.? I am using 2 ea 1 farad caps with my battery management system to
? ? ? ? ? ? ? ? ?sustain when switching.
? ? ? Conjecture
? ? ? ? ? ? I believe the only thing pulses do is cause the molecules to move faster, which does accelerate the process, but as Ron has
? ? ? ? ? ? ?observed, this is not enough to offset the off-time of the DC current
? ? ? ? ? ? A more managable means of speeding molecular movement is heat.? My consorts on a Electro-plating? Discussion Board tell me
? ? ? ? ? ? 20 Degrees C increase doubles the electrolyis (?)
? ? ? ? ? ? One area I have not abandoned is a design you can see on my website.? I used high voltage ignition coils to add HV spikes riding
? ? ? ? ? ? on the DC signal.? If I could get this right it should cause some agitation without dropping the DC signal ? I have suspended? ? ?
? ? ? ? ? ? testing this until I can convince myself conditions do not exist in my design to allow a HV arc inside the cell

As I said: most of this is conjecture.? I posted to prompt intellegent response, so? BRING IT ON

Bob at oupower.com forum stated, that he got very good
results using a full wave graetz rectified output of a staircase wave
inverter at around 730 Hz.
So he used rectified the AC to full wave chopped staircase DC.
As this staircase waveform tends to increase the voltage in steps it seems
be easier to break the water molecules with every step jump.

Also pulses which will have a rising envelope amplitude will work !

This was told, before Bob was silenced by a few patent holders.

So try it this way.
Also Stanley Meyer was using increasing amplitude pulses !

Could it be a bit of a shortcut to use a sawtooth pattern instead of steps to simulate the same effect and possibly simplify the circuit?

I was referred to this patent by a person on egaspower group

It uses a combination of pulses to get two different forms of hydrogen.  Anyone understand the chemi-terminology in this document?

It's an interesting approach.  Some of which I think I already accidently have going for me.  Like the pressure self-building part.......I can do that just pretty fast in my little setup.  I know I can reach 5 pounds before 5 minutes.  The patent says at least 1 pound a minute from tap water.  It also speaks of frequencies.  I'm using direct current but if you think about it, it's rectified so there are essentially "pulses" there. 

1800 rpm x 10 magnets = 18,000 rectified pulses
18,000 x 9 coils = 162,000 rectified pulses per second.

But I don't have the second low coil and frequency.

I'm currently trying to figure out what's going on that makes it so special but I don't understand the types of hydrogen mentioned in the documentation.
