EV's typically use 0.3 to 0.5 kwh/mile. Using electricity
with Olah's reverse fuel cell, electrolyis at 67%, reverse
fuel cell at 35%, fuel cell again at 35%, you need 3.6 kwh
to finally get 0.3 kwh to the wheel. Batteries and electric
drivetrains aren't 100% efficient but they certainly beat
those figures.

Isn't electtrolysis more like 45% efficient?
And you didn't factor in pressurization or the costs of hauling around a half
ton of steel bottles.
