P5 5 Nuclear Fusion: A Finite Resource?

Abstract

The studies in this paper explore the limits of nuclear fusion, specifically looking at deuterium
and tritium fusion, the primary fuels used in nuclear fusion reactors. The calculations within this
paper find that on Earth, the abundance of lithium-6 is the limiting factor in this reaction and the
ocean reserves would be able to fuel anthropogenic activities on Earth for 7.1 million years given
the total energy usage on Earth from 2023.
