Just wondering if anyone on here has any experience of protecting steel from corrosion by "Impressed Current Cathodic Protection" (ICCP) ?
For those that haven't heard of this before (including me up to yesterday), it seems ICCP is using a small dc power source to prevent current flowing away from metal into the surroundings and causing corrosion. It works on the same principle as attaching sacrificial zinc or magnesium anodes.
ICCP doesn't stop metal rusting in air, but it seems is very effective for anything that is immersed in water, or surrounded by soil.
This gives a quick overview
With a small solar panel and a simple circuit, it may have some potential for those of us who like to dabble with a few volts. I have a couple of things I may try it on. If it doesn't work, I should be able to let you know in another 10-15 years - if I'm still around to poke my finger through the rust
