Simple, i have learned that i don't need a hugh unit with 3 1/2" wide x 6" long 16 gauge plates drawing 25 amps and getting hot as hell. The system i just described to you is what most people are playing with. I went back to the drawing board and started with a paper clip and a 9 volt battery. It made hydrogen, so i built a full size model, my first problem was it just did not have the pressure behind it like the plates and high amp draw. So i tried putting some air pressure behind it, didn't work. I tried this and that and finally figured out the solution. The new systems are vacuum based with a bubbler that is actived by the vacuum entering the generator. Low and behold i had excellent gas output. The new systems connect to the motor in two locations. Because the vacuum is different at idle and driving. The bubbler actually helps free the HHO from the coils and mixes it up for the motor. The pcv enhancer removes the crude and crap that is unburned by the motor and reintroduces it as a cleaned up fuel. You would be surprized how much it does clean. It is used with the pcv valve on the motor. Like i said in my other post i use a little baking soda in the water, non toxic and helps the output. And no it does not create a vacuum leak or suck water. Also there is 12 feet of ss wire for the coil. The fuel heater helps vaporize the fuel in to the intake instead as a cool liquid. More even combustion.
