Steven Cowley: Fusion is energy's future

The video discusses the history and potential of fusion energy, starting with its discovery in 1920. It highlights current energy challenges, emphasizing the need for sustainable solutions like solar and nuclear fission. Fusion is presented as the ideal energy source due to its safety and inexhaustibility, despite its complexity. The process of fusion, involving deuterium and tritium, is explained, along with the challenges of achieving the necessary conditions for fusion reactions. The video concludes with ongoing research efforts and the potential for fusion to become a viable energy source by the 2030s.
