Let me get this straight. The theory is you use some other means to heat up the iron to its burning point (probably by burning fuel, unless electricity can be used to bring material >1000 C?). Then you can turn off the energy input because the fuel is burning, at which point it will oxidize on its own...? I'm not really sure I'm grasping how this is an efficient system
