What is the Iron Battery? How does it work?

The chemical concept

The whole concept is based on the different chemical states that exist for Iron. Indeed the reactions that happen  inside the battery to produce power is the following:


This reaction is enabled through a special design that was built up to make the reactant get in contact using only gravity, producing the following exchanges:

 As the discharged solution does not contain any toxical component , it can be poured out in the ground without any bad effect for environment or for the people around. Then putting new solution in the top recipient creates electricity again.

Use of the battery

Once the battery in your possession, it uses three different consumables to produce the desired power: Paper, iron salt, and iron. Water is added to the iron salt to produce the solution that goes down inside the battery.
