Further, the gain I'm looking for is nowhere near double efficiency... I'd be satisfied with a 5-10% increase since I'm getting the electricity and water for free.
I'll have a look at that video, thank you very much for the pointer.

The issue with on-the-fly generation is this: Let's say you have a 100w HHO generator. At 20% cracking to combustion efficiency, you're looking at getting 20w of hydrogen out of it. If you're cruising on the highway using 20hp, that works out to around 15000w of energy from gasoline to the wheels. A 100w HHO generator run off a battery thusly should cut around 0.1% fuel consumption. Increase it to 1000w and you're getting 1%.
