But hey, ze Germans and their Zeppelins are never wrong on hydrogen, right?

The Zeppelins were actually designed to be used with helium. Hydrogen was used because the U.S. (largest producer of helium) refused to supply it to post-war Germany.

Now, if BMW can make an X5 run on helium that'd be great, it already looks like the G 4 series designers were huffing nitrous oxide.
