Electric Seven

[Reckless Rat]

It's all well and good talking about there only being water as a by-product of a hydrogen powered car, which is true, but in order to acquire the gas, it is necessary to split water into its component parts by a process of electrolysis. It takes a HUGE amount of electricity to create sufficient Hydrogen for an automotive application, and on top of that, due to Hydrogen's molecular size you need a special high pressure tank in order to store it, otherwise the Hydrogen escapes by osmosis. On top of that, it is extremely explosive when mixed with air. It all sounds simple, but the required technology is complex, and therefore expensive. I remain unconvinced.

Cue videos of the Hindenburg and R101 airship disasters...
