Imagine thinking that a material stars can't use for fuel is one that makes sense as a "renewable energy source." These idiots need to go back and take undergraduate thermodynamics.

No one is talking about using Fe as fuel in a nuclear reactor, or (even though the article muddles this) as a primary source of chemical energy. Its a battery. A heavy, big battery.
- skyechurch 3y agoYou can't extract energy from iron by nuclear fusion, which is how stars "burn" fuel, but this is a chemical process, Fe + O2 => (some Fe&O compound) + energy.
