URGENT! WATER AS FUEL DISCOVERY FOR EVERYONE TO SHARE

[geovel56]

Hi All,

Here is our circuit:

We ran our first test for the plasma arc today!  I know the description following may be extremely basic and BORING for many in here, but as promised, I said I would divulge everything we did Step-By-Step, and explain it in the simplest of laymans terms, so that anyone that knows which end of a screw driver to use, can also do this!

Step 1:  Verify non-resistor spark plug. 
Attaching a multimeter set on ohms we touched the top of the plug to the little anode (not the "L") and got zero ohms.

Step 2:  Verified our ignition coil was good.
Again using the multimeter on the ohm setting, we set it to the 1 ohm position.  Taking one probe and attaching it to the "+" terminal and the other probe on the "-" terminal of the ignition coil, the meter read 1 ohm.  That verifies the primary coil of the ignition coil was OK.

Setting the multimeter to the 1K ohm setting we took one of the probes (it doesn't matter which one) and placing it into the center of the ignition coil (where the coil wire plugs into and goes to the center post of the distributor cap on a car), and the other probe touching either the "+" OR the "-" terminal (doesn't matter which one) on the ignition coil.  The meter read 11K ohms.  This verified the secondary coil in the ignition coil is also OK.

Step 3:  Testing the diodes
Again, using the ohm setting on the multimeter we set it to the 1K setting.  We touched the '+" probe on side of the diode that has the little bar printed on it, and the "-" probe on the other side.  It showed no resistance which is what we expected.  We the reversed the probes and the meter did not move at all, again, what was expected.  If there was any movement in that position, the diode has leakage and therefore bad.  We repeated this with every diode to verify they were good.

Step 4: Connected all the components according to our schematic

Step 5:  Test the "Points and Condenser" emulator
Leaving the diode chain, capacitor/diode in parallel, and leading diode from the inverter disconnected from the spark plug, we flipped the switch back and forth and got a good spark at the spark plug.  This verified our "points and condenser" emulator was working properly as well as verifying the ignition coil was putting out HV.

Step 6:  Testing whether the ignition coil is "+" ve or "-" ve.
We connected the diode string, the diode/capacitor parallel arrangement, and leading rectifying diode to the spark plug, but didn't plug in the AC.  We got NOTHING from the spark plug at all.

We quickly deduced we had an ignition coil that had a "-" ve discharge instead of "+" ve.  To verify this, we disconnected the entire diode string from the other components, reversed it's direction, and placed the string across the spark plug.  We got spark from the coil.  This verified we had a "-" ve coil.

Step 7:  Reverse the circuit for a "-" ve coil.
We reversed the capacitor/diode parallel combination, as well the leading rectifier diode coming off of the inverter.  We disconnected the diode string from the spark plug base and attached it to the capacitor/diode parallel arrangement and the now reversed leading diode.  Again, before plugging in the AC, we tested the spark from the HV.  We got spark every time we opened and closed the switch.  This verified the reversed circuit design for a "-" ve coil.

Step 8:  Plug in the AC

Step 9:  Fire up the circuit DRY (no water)
We flipped the switch back and forth.  We got good, not great PLASMA arcs although they were intermittant.  We observed the HV spark every time we flipped the switch, but the plasma arcs were sporadic.

Step 10:  Test the circuit with water.
We misted the spark plug with water and started flipping the switch back and forth.  The plasma arcs generated were substantially bigger and brighter arcs and louder bangs than when fired dry, however the plasma arcs were still intermittant and didn't yield an arc every time the switch was opened and closed, although we did get the HV spark every time.

A few comments as to why the circuit is designed as is.  The 30 1N4007 diodes are connected in series to prevent the HV from reversing back toward the inverter.  The 500K ohm resistors in parallel with each diode essentially equalizes the diodes. 

Sometimes a diode may not have all the proper characteristics as rated.  If one diode is actually weaker and internally not functioning up to specifications, it will blow and cause a cascading chain of blown diodes.  The 500K ohm resistors in parallel with the diodes equalizes the diodes.

The rectified AC LV side of the circuit will never see the 500K in forward direction because electricity will take the path of least resistance and flow through the diode.  In the reverse direction it will see the reverse opposition of the diode, but if the diode is deficient, it will also see the 500K ohm resistor and thus protect the inverter.

The diode in parallel with capacitor is another safety precaution for the inverter.  The lead diode from the inverter simply rectifies the AC to DC.  The 1 Ohm 40 watt resistor is another protective component for the inverter.

We are very happy about the first test here, but are pretty disappointed in the sporadic plasma arcs.  Does anyone have ideas as to how we can achieve plasma arcs every time we flip the switch back and forth as we have observed with the HV sparks?  Suggestions welcomed!

Regards,
Geo

OK, Trying again to get this to post on screen as opposed to being a file only.  LOL

Hi Geo,

Great job!  Inevitably I have a couple of questions though...

I can follow the step by step up until about point 7, at which point it seemed a little ambiguous.  Where reversing the cap/diode combination is that the polarity or the order in which they appear? Moving the diode/resistor string is also something I'm unclear about.  Is the circuit diagram after these changes? (I'm assuming so), in which case this is a circuit for a -ve coil(?).  Perhaps it would be possible to mark the points on the diagram with the steps in the description so that it's clear where we should be making changes.  Despite not being an electronics person, I can still follow most of what you're saying, or deduce what you meant, but some of it I can't. 

Great idea about the diode/resistor combo btw.  I guess that could have saved a few inverters

Wrt intermittent plasma discharge, if you have a smaller spark gap does it make it any more consistent (if less impressive)?  If so then it looks like it simply needs more voltage.  I have a suspicion about the diode acting as a rectifier.  I don't think it's acting in the way you believe it is.  Again I must stress that I know next to nothing about electronics, but wouldn't that only rectify half of the wave? and therefore be less power than you're expecting?

Finally, you have 2 x 12v sources.  Do they need to be isolated or can they be common?

Thanks again,

Shiver

Thanks Mr Copperpot 

I suggest reading the meyer notes, if you haven't done so, they give you all the details you need.
