Stainless steel comes in a wide variety of types and have a number designation that refers to the amount of other metals and carbon that are added to the iron when making the alloy. Types 304 and 316 are common types found in the retail market. One thing to remember is that even within the same number classification, there can be subgroups such as 304L and 316L which manifest different corrosion characteristics due to differences in crystalline structure.
For example the 304L and 316L types are less susceptible to intragranular corrosion.
Also there are are differences in magnetic properties. Type 304 is not magnetic but type 440 is
While Stanley Meyer makes much of the very low corrosion rate in the various lectures and his publications, (" They'll last for 10,000 years"), the appearance of a brownish coloration
of the water is likely due to the oxidation of the free iron atoms being leached from the vertical exciter tubes in his vertical cluster array model. Additionally
the construction of that cell included non stainless bolts that rusted. The repeated or continued use would concentrate impurities or other
contaminants that remained in the water contained in the Perspex (r) tube as the water was being was being converted to HHO gas. This would be analogous to concentrating
sugar in the preparation of maple syrup. (Although the method of removal of water is different, boiling versus the dissociation of water by a novel means)
Visual inspection of several photographs show the discolored water, the rusted bolts, and the difference in the appearance of the surfaces of anode and cathode due to the different curvature of the inner and outer
electrodes having a different surface charge density Also the cavitation effect and rising bubbles may be causing a scrubbing action

In my opinion it's ok to has some corrosion of the small lattice iron granules on the surface of the stainless tubes as this is
providing a rougher surface similar in concept to sanding flat plates to create cross hatching but on a a much smaller scale
The roughened surface provides a nucleation point for bubble formation just as the conditioned surface is recommended
