Thorium, element 90 on the periodic table, is a fertile material. When struck by a neutron, it will change (over time) into Uranium-233. Uranium-233 is fissile, and can fission into energy and fission products.

Claims have been made regarding both thorium's energy potential, and counter claims that it holds no particular advantage over uranium as a nuclear fuel.

This video seeks to clarify this dispute.
