Hooked it up to a 2003 civic, cell was inside the car in the passenger foot well, with 10 ga wire direct to the battery with a inline 55 amp breaker. Ran good for about 15 minutes, then things started to get hot. Wires were getting hot and the water was almost boiling, it finally tripped my 55amp circuit breaker, so i might have to try another cell design, or use a reostat or potentiometer to limit the current. I have learned much from this. I think my electrodes are to far apart causing the high amp draw because it takes more to get the current through the further distance of water. Therefore the water gets to hot because theres alot more resistance. I will post a picture of the electrodes and you will see what i mean. And i did have a crap load of baking soda in the water, still not sure about the amount, i just dump a whole bunch in lol i will post pictures of my original design

Another thought i have for my next design is the size of the electrodes porpotionatly to each other, For some reason i have stuck in my head that the negative electrodes should be 2/3 bigger than the positive ones because hydrogen is produced at the negative electrode and oxygen at the positive, HHO > 2 hygrogen 1 Oxygen. I'm wondering what you guys are finding with the size of electrodes??.

My next design > 15 plates 6" by 3.5" to start with. Maybe cut the positive plates down 2/3 like i said to 2" by like 1 " . OR leave all the plates the same size??? i'm not sure yet which i should try. The plates will sit inside my 4" ABS pipe from my old cell and tie in with stainless bolts offset to each other with little tabs connecting every other plate to each other
.

so +n-n+n-n+n-n+n-n+n-n+n-n+n-n+ pretty straight forward
