Or we can learn how to fully convert matter into energy, and use the
energy to transmutate iron into more desirable elements. According to this
web page by the French atomic energy commission,
( we
can potentially do matter-to-energy conversion by catalytic conversion of
matter into antimatter, or by creating a small black hole and capturing
its Hawking radiation as it evaporates.
