       Real-life Rupees: How to Grow Green Potassium Ferrioxalate Crystals From Iron Rusthttps://crystalverse.com/potassium-ferrioxalate-crystals"A more efficient way of making rust is via electrolysis. The disadvantage is that it requires a power supply."Idea: is electrolysis efficient enough to sabotage infrastructure with it over time? Eg wire up a power source to something like a bridge?This wouldn't often happen naturally as most leakage currents from power infrastructure are AC, not DC.

       @peteIt's probably a matter of power applied.With an aluminum boat hull, yes, stray current from normal systems can lead to perforation within hours.With a steel hull, iirc, it's more like days.Paint is also a factor.Metal boats usually have a leakage current alarm and periodically replaceable sacrificial anodes to protect against this.Seems like bridges might use sacrificial anodes as well: https://www.dot.ny.gov/divisions/operating/oom/transportation-maintenance/repository/CathodicProtectionSystems.pdfTram lines can provide the stray current:https://www.researchgate.net/publication/273770635_Protection_of_Bridges_Against_Stray_Current_Corrosion
