Perhaps I misunderstood, however I think you said that you can't get anymore enery out of the hydrogen splitting from the water molecule and being used in the engine, than it takes to split the hydrogren off from the water.

You asked about conservation of energy, but it must be understood that water in a molecular form already contains a good amount of energy stored up (in the molecular bonds), and while it does take a good amount of energy to split the molecule, it's not nearly as much as it would take to construct a water molecule.

Were you saying that the amount of energy produced by the hydrogen would barely make up for the energy needed to split the water molecules? If that's what you meant, I think you would really have to put a better test to that theory than just figuring it out in your head.

Think of it this way... it takes a good amount of energy to initiate an atomic explosion, but the breakdown of a single hydrogen atom at the molecular level (as opposed to the chemical level, which is what we deal with in the engine) creates much more energy in the explosion than it takes to initiate said explosion.

Am I wrong? Did I miss your point?

Would you like to buy my '91 Red NA 300ZX?
It has the following:

JWT POP Charger
HKS Exhaust
Axxis Metal Master Brake Pads
ACT Clutch (Modified Street Disc)
Wings West Body (without the rear valence which sucks IMHO)
Just painted with Redline Red (350Z color)
