"Der Traum von der Kernfusion" ("The Dream of Nuclear Fusion") is a German science documentary on the decades-long effort to build a fusion reactor — the attempt to harness the same physical process that powers the sun as a source of clean, abundant electricity. The film takes viewers inside leading research facilities and follows the scientists working on magnetic confinement, plasma physics, and reactor engineering. It also looks at the ITER project and the political and financial scaffolding around international fusion research. Through interviews with physicists and energy experts, the documentary explains both the science and the scepticism: why fusion has always been "thirty years away" and what would change if the current generation of experiments succeeds. Part of the Kantara Films & Documentaries archive, it reflects the production company's interest in science, technology, and energy policy.
