Summary: DeepMind, an AI firm backed by Alphabet, is collaborating with the Swiss Plasma Center to develop an AI system for controlling nuclear fusion in tokamaks. Fusion, a potential clean energy source, requires precise plasma control, achieved through magnetic coils. DeepMind’s AI, employing deep reinforcement learning, autonomously manipulated plasma shapes in simulations and real experiments. This breakthrough could expedite fusion reactor development, especially for larger tokamaks, by improving control, optimizing heat transfer, and preventing plasma instabilities, potentially advancing the path to practical fusion power.
