So....if an internal combustion engine could actually run on water, how high would the theoretical (magical?) compression ratio/cylinder pressure need to be to generate enough heat to break down the water into it's hydrogen and oxygen components, and then ignite the mixture?

I don't know if it's even possible to make a mechanical molecule-smasher...but I'd think the required forces wouldn't be practical.

I do know that I haven't seen a process that yields more energy from the resulting hydrogen than it takes to produce it in the first place. Sadly, it seems that the conservation of energy laws still apply here.

A close cousin (although a bit backwards) is the hydrogen fuel cell.

In case you're interested. That will show up as a viable source of energy in cars if the momentum stays the same.

I bet if Ford built one they could get it down to about 9 mpg.... :lol:
