From a thermodynamic point of view, it is not impossible that introduction of hydrogen into the combustion chamber could increase the efficiency of the engine at burning gasoline, thereby scavenging energy from the gasoline that would have otherwise been blown out the manifold with the exhaust. It’s likewise not impossible that the quantity of energy scavenged from the gasoline through a better, cleaner burn might exceed the quantity of the energy initially required to electrolyze the hydrogen from the water. I think you make a valid point. The title of the article is misleading and deliberately provocative. It causes people who have a technical background to scoff, and it doesn't give the idea a serious audience. Everyone posting on this thread knows that you can't hydrolize water and then burn it and come out ahead, if hydrogen is all you're burning. But this guy is using a mixed fuel of hydrogen and gasoline. I am skeptical, but would like to know more.
