As fossil fuels near depletion, nuclear fusion promises unlimited power supplies. This program looks at recent developments in the quest to turn the mechanism of the sun into a viable energy source. The program chronicles the efforts of Alan Sykes and his team working on START, the first spherical Tokamak, at the Culham Research Facility in England. Dr. Martin Peng, who first conceived of a compact, spherical plasma reactor, is also interviewed and discusses the American offshoot of the START project, the National Spherical Tokamak Experiment.
