Now this sounds interesting, like the propane used on diesels. What
about the storage of the 2H2O2 gas ? Is it in a high pressure tank ?
Sounds a bit like a bomb without the detonator. What does it take to
detonate such a device ? If the gas flow is on (thinking like a scuba
diver here - never holding your breath your lung pressure is always
equal to that before your face) wouldn't an ignition of this gas line no
matter how far from the pressure tank be the same as lighting a fuse on
an old iron civil war bomb ?

The way these things are used in auto engines, is that the water is
hydrolyzed, and fed into the intake.  There is very little hydrogen gas
at any one time.  It's used as it's converted.  There is enough to
possibly blow up the container, and you could put your eye out with
flying shrapnel.

So, you carry water, electrolyze it with current from the engine's
alternator and burn it as you go ? Seems like you'd need a larger
alternator just for this process.

And more HP is consumed by the larger alternator. One HP for each 600 watts
assuming the alt. eff. is 80%. At 12 volts 600 watts is 50 amps.

So how many volts and how many amps are required to make x amount of hydrogen?

Paul,

Ah this is the question.   I haven't a clue yet.  Depends on the engine
output of course. If we are speaking cruise power 100% hydroxyl gas,  and
running an engine putting out 200hp then:

It has been stated that an engine will run on 4% hydroxyl gas, and lean
mixtures of 1:25 so I am assuming this gas is at S.T.P. However we don't
know the concentration and hence mass of the hydroxyl fuel.


The PDF report I mentioned in an earlier post stated one guy dynoing his
twin cylinder 650 cc marine engine at 114 hp at an measured gas input of 60
liters per min. That seems a high hp figure to me so I am assuming his gas
must have had a fairly high concentration of hydrogen in it. If mono atomic
then about 4 times the amount of hydrogen. This fellow, Bob Boyce is
reputable, made racing boats in his spare time running on the gas from his
electrolizers, is not in business to selling his systems, but put his
detailed designs into public domain for anyone to use. Several people to
date have replicated his results.

I might add that Bob's unit is a sophisticated unit using, both electrolyte
and PWM shaped waveform resonating the 316L stainless plates. His 61 cell
unit used less than  11.6 amps at a 13.7 dc volt input and ran a mid size
car engine at highway speeds without gasoline.  That statement could be
intrepreted to mean about a 40 hp. output if on the highway I am guessing.

With the resonating type of waveform generator circuit, Dave Lawton was
getting gas production on less than one amp but his cell runs cold.  No
electrolyte was use but very close spacing and preconditioning of the
cathode and anode was needed. His pipes design resonant the most of any
design (and well they should) which made me think at first he might have
made a very expensive ultra-sonic water mister.  However he claims the gas
is burnable and does run the output through a solution of water to act as a
flasbback preventor.  I am working to reproduce his unit now because it
seems to have the best output for such a small size.

If you examine the output of most of these devices on the market, and
internet, their anode cathode stack is to small to  put out much hydrogen. I
suspect in the cheaper designs that they are just vapor ware and that a
person could get the same mileage results by blowing water vapor into the
engine.  After all, older cars used to run much better during damp rainy
days but now we have ECU devices.

What is definitely interesting in the sophisticated resonating electrolizer
is the sharp spikes the wave forms that appear to operate below one amp and
are cold to touch. I have to prove this out though.
