In 1903, how often did automobiles break down, hmm?
In 1903 automobiles were chosen freely by those who could afford them as being vastly superior to the horse. You know, it's funny I don't see any big line forming to buy fuel cell vehicles. And electric vehicles - well we all know how they took the marketplace by storm. (not) You'll have to do better than that.
I assume from your handle that you are familiar with the first and second laws hmmm? Then you are fully aware that H2 formed from fossil fuel is just adds additional inefficientcy to the burning of the fuel. You'd get more useful energy out burning it directly wouldn't you?. And as far as electrolysis goes, this is the most expensive H2 around. (I misspeak - H2 in space is much more expensive. Electrolytic H2 is the most expensive H2 on the planet)
