The Advancements Are Mostly in the Theory or the Engineering Front?

This is a conversation with Thomas Sunn Pedersen, Director of the Stellarator Edge and Divertor Physics Division at the Greifswald branch of the Max-Planck Institute of Plasma Physics in Germany. Thomas explains the progress that has occurred in fusion research over the past few decades, and how far away are we are from creating practical fusion reactors. He also discusses the obstacles that still need to be overcome, and the potential social, political, and environmental impacts of fusion technology.
