Let's be logical then. How does a "big battery" electrolyze water into H2 and O2 give a better range than using the electricity directly to power a wheel? Rough efficiency estimates tell me for a 1000W input, you can put 800W to the ground using a motor, but splitting water (40%) to fuel an engine (40% at best) (a fuel cell?) puts 160W of that 1kW to use.

Let's define "work". Can you split water and burn it? Yes? OK, it works. Does it net work? NO, it is a LOSS.
