If you want to lunch a spaceshuttel the price of the energy that you need to split the H2O is pretty cheap compared to the other costs that you have when you want to build spaceshuttels. That doesn't mean that it's a cheap way to fuel other vehicals.

Not as I see it. The commercial Hydrogen On Demand units that are sold and people are using now, uses 1.2 volts from the battery.
Punch HHO - Ultra High Output HHO Cells
The result is 130 octane Hydroxy gas that is supplemented to lower Octane gasoline. Thats 130 octane fuel.
1.2 volts to achieve 130 octane burnable
Supplemental fuel (not direct fuel) ? In my book thats a system that is highly energy efficient.
Now if you want to power a vehicle directly from Hydrogen. Use solar panels to power the process of electrolysis, which splits water into hydrogen and oxygen. Transfer to a storing device, which can then be used to run fuel cells. Use these fuel cells to power your electric car or a Blue tec Engine.
