Thanks for all the feedback,
Thanks for all the feedback, guys. My conclusion after writing this was if we can use fuel cells to make electricity to run the cars, why not use hydrogen to just make electricity in the first place (if that's viable) and drive electric cars?
As far as the Hindenberg is concerned, what I got from my research is that static ignited the hydrogen, thus burning the framework, sending the zeppelin to the ground where the diesel fuel used to power the propellers continued to burn for some time.
Static, flammable materials, hydrogen and diesel fuel do not a good equation make.
But you're right John. Hydrogen burns in a flash and does not leave anything to continue burning unless it manages to ignite something nearby, but I've never seen a car explode except in movies and one semi on the news. Did see a cartoon-like framework of an RV in Yellowstone, It was left when a 50¢ engine part failed setting the big box on fire.
