The water is split via electrolysis preferably using electricity from renewable sources. The stored hydrogen is then burned in the cars fuel cell using oxygen from the surrounding air. There is nothing magical about it.

    Yeah, but this isn't about real hydrogen fuel cell cars. This is about the urban legends about cars that run off water.

    The urban legend usually just leaves the electrolysis part blurry. They vaguely call it a machine to process or prepare the water, and completely ignore the electricity going in. I.e. hydrogen cars, being "suppressed" by the government.

    The urban legend goes back a long time. I first encountered someone telling specifics around 15 years ago, but the vague concept is much older. It's similar to the legend that there's a specially tuned carburator (yeah, that old) that would give you 100mpg, but it was killed by oil companies.
