Guest: Philipp Sauter (Max Planck Institute for Comparative Public Law and International Law). In this episode Christopher Murphy talks with Philipp Sauter about nuclear fusion. As opposed to nuclear fission, i.e., splitting a heavy atomic nucleus into smaller nuclei, nuclear fusion uses the opposite approach to combine - or fuse - light atomic nuclei into heavier ones. Through recent scientific breakthroughs the possibility of using nuclear fusion to provide the world with a practically inexhaustible source of green energy has become tantalisingly close. Consequently, the time is right to discuss how this tremendous power should be best regulated to ensure maximum safety while not stifling scientific ingenuity.
