The filament is actually more like a glow plug--looks sort of like a small spring stretched between 2 terminals suspended in the middle of the gas accumulation chamber. I have read of a few people who managed to "explode" their chambers if they ran the unit through several of the gas...

Thanks for the link--I did a lot of web searches but hadn't found anything like this. When you mention the high-powered buffer, would that still be a completely DC system? Guess if possible I was hoping that I could keep this all DC so that we can take it out in the middle of a field, etc...

Guess I didn't think about the fact that during the phase of H2 generation when it's not pulling 6 amps, the equation will no longer be valid and my voltage will not be constant, so perhaps this will cause a problem elsewhere?

Phrak, It takes about 5 minutes to bubble (has a solution of citric acid in the chamber and a catalyst which I think I read somewhere is made of zinc), then goes into countdown mode and you push the launch button which basically energizes the filament to make it glow and ignites the small...

The 3 volts being the drop that I'm looking for--right? Would putting the 2 of these in parallel be the equivalent of a "zener diode"? Somewhere I read that a zener diode would do it, but it seemed as though none of the parts they listed on that site would handle the watts needed? Will these...

Any EEs out there who can help me with a circuitry question? I purchased an Estes rocket for my kids that uses a small chamber to run DC current through water and produce hydrogen which is, in turn, the fuel to launch the rocket. It's great when it works but the problem is that it runs on 6...
