Electrolysis of water

Hey /sci/,
Is carrying around a battery and a liter of water an alternative to carrying around a helium container?

A liter of water makes about 1200 liters of ideal H2 at STP.

He's criticising you for confusing hydrogen gas with helium, though your post is less than clear.

The main problem with the Hindenburg wasn't the hydrogen gas. Tons of blimps had been using it without issues for years. It's perfectly safe if you keep oxygen away.
The problem was the paint used on the hull. The hydrogen didn't help, but it would have crashed and burned (if less spectacularly, though not likely with fewer victims; only thirty-six people died, after all, and most of them died from jumping from the blimp, not from the fire) either way.
