WARNING!!! My method on cracking water for fuel can be a dangerous experiment if you are inexperienced or careless. High voltage along with explosive hydrogen gas can kill you and others in the immediate area. Extreme caution is advised. Build at your own risk.
The capacitive discharger is my preferred method of splitting water for fuel. (Also see the 'Hydrogen Generator' section) I use a 12 VDC inverter with a 220 AC single phase output (220 AC on one lead). The 220 AC is fed through a 5 or 10 amp fuse into a 480 VAC- 24uf 50/60 hz capacitor. The output is then connected to a 6 amp 400 volt bridge diode for a pulsed DC flow to the anode and cathode assembly. No DC filter is used. The discharger produces a high DC pulsed voltage at low amps. Aluminum anode and cathode spacing must be experimented with for the best results. I use only baking soda and water for the electrolyte mixture which only produces oxygen and hydrogen. Other exotic mixtures you read about can be hazardous to you and your engine. The cheapest inverters are the 50 Hz models made for europe applications. They will plug right into your car 12 volt electrical system and produce the required 220 AC single phase output for the discharger. These small units have a rating of 200 watts with a 400 watt surge capacity. See schematic below. Build at your own risk.
NOTE: The trick is in the square wave output of the inverter. The square wave is a sharp low amp extended pulse at 50 cycles which easily splits the hydrogen oxygen bond in the electrolyte. This is more efficient than using the standard bell signature wave from the grid.
