Galvanic corrosion
I'm no chemist but I'd agree that I don't see how it works if it's not completely submerged as it's the water that earths the current. If it works we could also just treat our steel cars like oil rigs and bolt a lump of alluminium to the chasis! Whenever I don't see miricle before and after photos by a non-affiliated examiner I have my doubts!
