No, but I DID invent the "Rusty Water Reactor" that will revolutionize the fusion power industry!
The easist way to visualize how the anodes are supposed to work is this: They GENERATE a DC voltage that protects the hull; from 0.9 to 1.2 volts is the range we're looking for. If less than 0.9 volts ("9" on the CAPAC meter) you need more/ better/ cleaner or different (magnesium) anodes. If more than 1.2 volts you need to remove some anode(s) to prevent leaching magnesium out of the welds.
Simpler to think of that way, right?
