doncityz: I would like to know what flow rate do you expect the prototype you are doing if you don't use catalyst? I guess its hard to generate enough oxyhydrogen if you don't add catalyst. Our tested unit with catalyst, drawing 30amps will only have a very very very low flow rate which is 50L/hour or less if i was not mistaken. Have to check back the report.
Basically, with or without catalyst, the unit will also generate oxyhydrogen. It won't pollute the water.
As for the corrosion, I'm the one to witness and clean up the whole intake manifold. Just to make this clear, the gas that are generated will be Oxyhydrogen (Brown gas) and not pure water vapor. I'm lucky to found out this problem early. I have tested it for 4000KM when i realize this problem. It corroded part of my intake manifold and built up composites on the manifold. If I discovered this problem abit later, I guess it will corrode the engine valves.
But don't worry about this issue anymore as you can get the water trapper or dryer to get rid of this problem. If you need this, I can tell u wat brand we are using.
I want to ask, your prototype unit is planning to draw how many amps out from the battery?
