acid rain and catchment thread

Yes, the issue is that when you use two metals that have different electric potentials in contact with each other, electrons flow from one to the other like a battery causing rapid corrosion. This happened with the fencing at Kulani because they used galvanized steel fencing with stainless steel T-posts and wire. They're both rust-resistant, right? Not when you put them together...
