Fusion Energy (Part I) — Prof. Steven Cowley

In 1920 Sir Arthur Stanley Eddington conjectured that “fusion” of light nuclei to form heavier nuclei is the power source of the sun and stars. He also conjectured that one day humans would harness his energy source to power our lives. Fusion is not easy — it requires that the fuel (in the form of a plasma) be heated to temperatures in excess of a hundred million degrees. This talk discusses the physics of fusion and the various methods proposed for obtaining the requisite temperatures. The Joint European Torus experiment in the UK has achieved considerable levels of fusion power — 16 megawatts. Now the world is building ITER — a fusion device that is predicted to reach a self sustained fusion burn.
