2000 degrees celsius or thereabouts to break H?O covalent bonds down to wind up with 2x H?O >> H? and O?
Engine blocks don't like 2000c, not much does.
So Thermolysis is pretty much out the window.
Electrolysis takes a fair amount of energy to smash the covalent bonds too, water needs to be less than pure (pure water is self ionising so it takes a LOT more energy to pass a current through)
you need to use expensive metals like platinum too in order to achieve usable results, Hydrogen is Positively charged, oxygen is negatively charged (water molecules actualy arrange themselves like compass needles) this means that the atoms can be collected at the correspondingly charged electrodes.
Hydrogen production here isn't exactly efficient though, on paper one oxygen atom with two hydrogen atoms bonded to it should smash into 2 hydrogen and 1 oxygen, this doesn't always happen and yields do vary, not to mention that because your not using pure water deposits also collect at the anodes and cathodes reducing efficiency further and causing the need to replace the expensive platinum bits...
Hydrogen powered cars sound GREAT on paper but in realistic terms they're pretty difficult to manufacture, require a lot of energy put in to get the hydrogen (outside of producing it from hydrocarbons IE: oil) and need regular maintainance and replacement of rare heavy metals.
So to run a cheap hydrogen car most of the hydrogen would come from the very oil its trying to work around...
