If you actually read Dr Karl's commentary (instead of just misquoting him) you will see that he is talking about cathodic systems (as used on ships and bridges) that require the metal to be under water. He explains that such a system doesn't work once the metal is not under water.
I have never heard Dr Karl comment on Capactive Coupling systems such as the ERPS or CounterAct. These systems have been trialled and used sucessfully by Queensland Transport, BHP Mining, SLSA, and
Brisbane City Council.
