Water4gas

HHO...Brown's gas...whatever they'll call it, as it's an electrolytic product of water, it will take more energy to produce than combustion of the resulting components will yield.
I have a chemistry background (albeit very rusty from disuse) and agree completely with this statement within the context of using the liberated Hydrogen and Oxygen as the actual fuel. I'll have to look at this thing more closely, but I gather that the idea is separating the gases without diverting them into separate vessels. Then this weird (and apparently somewhat stable? hmmm...) mixture is introduced to the vaporized fuel stream and acts to further reduce the size of the droplets through reducing surface tension or some such thing. I dunno... there are many question marks here. The net result at a glance is that the fuel charge has much greater surface area and is thus more efficiently burned.

I'm probably missing tons of stuff. It'd probably take a while for me to balance even the simplest equation at this point.

I hope that I've thoroughly confused the issue for anyone with the misfortune of reading this fatigue-induced rambling. ;-)
