Nuclear Fusion
Season 4
Episode 1
Fission, the splitting of atoms, makes the heat that drives our nuclear reactors. Fusion, the fusing together of atoms, powers the stars, including our sun -- which means that fusion already powers Earth, just not in a way that we can control. If we could harness fusion, it would transform our world, producing limitless energy, safely and without emissions -- the holy grail of energy.
