Real car that runs on saltwater

41. It's a metallic salt, not "saltwater" as most people think of it.

When lay people think of salts, they think of harmless table salts or seawater. In chemistry, a salt is what you get when you neutralize an acid and a base, and it can contain all sorts of nasty ions capable of melting the skin off your hands...and of carrying an electric charge.

Based on their engines name, it's probably safe to say that their "breakthrough" is based on some nano polymer flow battery improvements that made the rounds in tech news circles last year. If so, then we're probably talking about metallic salts embedded into polymers. Cool, but not as environmentally friendly as the "saltwater" that most lay readers would assume they were talking about. And their comment about the expended electrolyte blowing away as dust sets off my bullshit detectors. Metallic salts, released into the environment in sufficient quantities, would be enormously harmful.
