Iron is one of the most abundant elements on earth, but also we aren't going to be burning it like we do fuels now. Instead we would produce pure iron using green power and oxidize it back to it's natural state for energy in a cycle.

Imagine loading an iron rod into your car, driving for a while, and then when you get into the gas station you dump a pile of rust off and buy a fresh iron bar.

Some societal implications:

* Kids playing with iron filings sounds a lot safer than kids playing with gasoline. "Don't leave your magnets in the fuel tank; it clogs up the lines!"

* The gasoline party scene in Zoolander would need to be reconsidered.
