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 Ossi,
great new tests and circuit.

Did you already take any scope shots of your 10 uF cap voltage ?

How does the voltage on the cap fall during the sparking ?

Maybe if you have a high voltage scope head can you also
show the voltage at the spark plug directly ?

Be carefull not to kill your scope with the high voltage
spikes...



@Luc,
your new circuit makes not much sense to me.

The effect is, that a high voltage spike from the ignition coil
creates a ionized conductive channel for the low voltage cap charge
to be discharged and instantly creating steam and electrolysed HHO,
which burns off in a Bang...

So Ossi?s circuit is exactly right,
just charge up a capacitor and trigger the sparkgap with
high voltage to make the sparkgap conductive, so the cap can
discharge in an instant and can evapourate and electrolyse the water droplets.

Because of the evapouration and the heat it consumes the sparkplug probably stays pretty cold
as Ossi has found out.

Now the question is,
if we can make this also on a bigger area, not just on the tiny small
contact point of the sparkplug...

If we could explode and evapourate the water droplets on maybe 2 x 2 inches
altogether, that would really give a nice explosion cell !

The question is, if the best application for it is
really inside a cylinder to propell a piston or
if it could also be used in other way, e.g. via the idea
of a MHD generator to produce electricity...

xbox hacker, good job. That set up I could see being in s1r's container.



Luc, can you confirm it for us as to working as desired?

Hi Gotoluc

Great work!

I tried a simple test to see if I could get the water to "burn" and it wasn't that hard to do. I used a small TV chassis to feed High voltage to a pair of microwave capacitors wired in parallel and then to a spark plug with the resistor removed. It would charge the capacitors and discharge at it's own frequency with a very strong white spark.  When I sprayed water on it (FINE MIST) it would flash a bright orange flame much larger than the original spark.  The effect lasts for several other sparks until the water burns off.
I am truly amazed that a simple high voltage setup can actually flash water.

Here is my setup.

That is very good if you're getting results with this even more simple circuit. Can you measure the DC resistance and henries (if you have a meter) of the primary of the coil and post it please. I think that will also play a part here.

Great job there xbox hacker
