All,

People are overcomplicating the circuit and process for nothing. It is VERY SIMPLE to get water to explode with little energy input in the spark plug discharge of an ignition system. All that is needed is a small cap of a few hundred volts and a few uf and a high CURRENT high voltage diode, placed in series across the spark plug. You can use WHATEVER to charge the cap to a few hundred volts DC. An inverter, oscillator, anything.

All you need to do is make sure that the series loop of the capacitor, diode and spark plug is very very low resistance. In fact as low as you can get it for your components. The lower the resistance of this loop, the lower the energy input requirement is to make the water explode. It is possible to do this with even a few hundred milliamps.

The key component here is the diode. It MUST be a HV diode to protect the capacitor and power supply from shunting the ignition pulse but it also MUST be a HIGH CURRENT diode to reduce the series loop resistance as much as possible. A microwave diode is a good HV diode but it is NOT a good high current diode. The diode must be able to handle very short surges in the hundreds of amps! This is why I use many 1N5404 diodes in series. These are 400V 4 amp diodes they can handle surges in the hundreds of amps. Putting them in series turns them into a single HV diode capable of handling thousands of volts. If you have many microwave oven diodes then put as many as you got in parallel. But they are expensive so it is much more cost effective to simply use many 1N5404 diodes in series or series parallel combinations.

As I have explained the circuit requirement and operation to explode water in an ignition is very simple. So simply that no one will believe it but it just is. S1r9a9m9's circuit uses heavy 60 amp diodes but is too complicated and not necessary. His use of coils is simply to get the same effect as a capacitor, just in an inverse reactive way.

There is no energy gain in this circuit! The in his circuit the measured difference between 36K 0.8 amp input and 24K 6amp output is just what his meters are showing when the ignition pulse and the inverter pulse is mixed. It is NOT real power. The real power and energy and magic is the the water explosion itself. This is the only place in this circuit where something unconventional is occurring.

The energy appears the be negative in this explosion.

ONCE a PSI value for normal combustion is established   replacing the plug with one of these circuits[and water instead of gas] will tell us how much power we have compared to normal ICE spark  Chet

Been following the S1R water car for awhile now. Glad I came across this site and this particular post. I have very little understanding of electronics but I have great mechanical/fabrication skills. I tried replicating callanan's first diagram he posted and cannot get it to work for me. I get no high voltage spark unless I unhook either side of the bridge rectifier. I don't have enough electrical knowledge to know what's going on with it but if somebody will post up a simple design that actually works then I can have this on a small engine in a flash and see what happens.

Gimme the electrical and I'll do the mechanical basically is what I'm saying then I'll post a video if it's successful.

UPDATE!!!!!!!!

Drop the bridges you dont need them!! here is a diagram of my working circuit!!!!!
IT WORKS!!!!!
Keep you spark gap @ .050 - .060... too small and the inverter bogs down @ .050 and up it runs normal!

It has a nice BRIGHT flash and a big SNAP! I do have a video camera, but no way to get too to the computer (i am working on that now) 

ALSO... dont try to gap the plug with a metal gap-er while the inverter is on....LOL....OUCH!! 

Hi Xbox,

Your circuit will work for a while, then the inverter will blow.  When the air/water ionizes, there is a dead short across the inverter output.  The only thing saving your inverter right now is the considerable voltage drop, 1/2 wave rectification across the Microwave diode and that is what is keeping your inverter alive. 

The beauty of your circuit is its simplicity and it is technically correct but it is just a pure brute force inductive supply with no limiting of current.  Design wise, will give you trouble down the road.  As pulse rate increases to coil, it will become a hit and miss mess as no syncronization with pulses from inverter.......For a basic demonstration unit, a good idea, as a motor driver, no banana.

OSSIE seeing first hand the effect   what do you think is going on here combustion? like the MEYER spark plug ?  Chet
