Hydrogen definitely fits in there somewhere. The Hindenberg photo is funny but far from an accurate reflection of reality.
In a car the hydrogen would be much higher pressure and enclosed in a metal can that would act like a rocket IF WHEN damaged.
Sounds strangely like President Bush's energy plan that has been bottled up in the Senate for the past 4 years by John F'n Kerry and his demomarxist, treehugger-pandering cohorts.
