Summary

This 1988 documentary, ‘Sun of Man,’ provides a comprehensive overview of the state of nuclear fusion research at the time. It begins at Princeton Plasma Physics Laboratory, where scientists are working on the Tokamak Fusion Test Reactor (TFTR), aiming to achieve controlled fusion. The film explains the basic principles of fusion, including the use of deuterium and tritium, and the challenges of confining plasma at extremely high temperatures. It then visits Lawrence Livermore National Laboratory, showcasing the Nova laser for inertial confinement fusion. The documentary covers the history of fusion research, from early claims by Argentina to the declassification of research in 1958, and highlights the contributions of scientists like Lyman Spitzer and Andrei Sakharov. It also discusses international cooperation, including Soviet tokamaks like T-10 and T-15, and the prospects for ITER. The film addresses funding issues, materials challenges, and the potential for fusion to provide clean, abundant energy. It concludes with reflections on the commercial reality and the long road ahead, emphasizing that fusion success is always decades away but remains a crucial goal.
