The principle has been around at least as long as the "300 mpg carburetor"; it
actually does work under some circumstances. Sometimes used on ocean-going
ships & whatnot. But unless you have a Amphicar, I can't see it being of any
use on a car. It only prevents electrolytic corrosion, when the body is
immersed in a conductive liquid to close the circuit.
