I pretty much ran into the same issue. its easy to make, and really nasty to make a mistake with. So cheap, easy, simple, probably isnt going to happen. if the Hydrogen was 100% pure and contained, it is my basic understanding that it would not be explosive until mixed with oxygen or some other component. It is also my understanding that buying hydrogen already in a tank is not a lot more expensive than making your own and just paying for the power used. I personally would love to run a car off hydrogen. But its not as simple as it seems. more oxygen is required than air will provide for most car/truck performance. For instance you might find that you have the power loss as if you used propane instead. that brings me to the reason I wanted to collect my own. So i could have the oxygen too and use both to fuel a car or truck. That application could get pretty dam tricky fast because of the explosive nature of H and O. some day i will tackle it, who knows what I might get from doing it. probably a lighter wallet heh.
