So while Brown's gas is less powerful as a combustible than you think, the real problem is that, in essence, it is not a combustible at all. It is an explosive, and as an explosive it has no equals when it comes to bang per weight.
When it explodes it will not complete the reaction; the temperature gets so high that some of the hydrogen and oxygen start to lose their bonds again, and the reaction will only complete when it can shed its heat or mix with the surrounding gases.
Yes, I was worried about that too.
I dropped the concept and won't work it out, but just for the hell of it, I'll calculate it out further in this thread.

I indeed don't listen to idle comments. I only listen to comments that are backed up by hard data. So, if you reply to me and include calculations to back up your thoughts, I'll listen.

I've been working on related issues since many years. I never did the calculations on hydrogen though since I also always considered it a lost cause. However, given that it is a completely clean fuel (and little other transport technologies are, -and if they are, they're expensive, ie batteries/electric motors-), I'm reconsidering it, and trying to make it at least better then the current way of using hydrogen.
