This is an interesting proposition. Iron isn't toxic, whereas other mixtures such as nickel-iron are. Iron is also readily available. I searched for additional details about iron batteries and their benefits including how long they can last (15 years or more would be ideal) as well as energy density, but have not been able to find much information. More research is needed.
