How to keep the steel from corroding given the chemical exposure and likely levels of electrical current during storms (they have those in Florida)? My guess would be that titanium nitride would work great since it bonds well to steel, resists corrosion well enough for medical implants (unless heated to 800C), and conducts electricity well enough for tiny electrical circuits (unless chilled to near absolute zero) despite being chemically a ceramic. Of course it is expensive.
