Nuclear fusion, an energy generation method driven by the combination of two hydrogen atoms, has long been sought for its potential as a near-limitless source of energy. In the pursuit of cheap and attainable fusion energy, scientists recently achieved an important breakthrough drawn from an unlikely source: video game technology.Drawing from algorithmic innovations in the video game industry, researchers from the Ulsan National Institute of Science and Technology (UNIST) in South Korea were able to achieve a 15x increase in computation speed in predicting where and when particles would collide in nuclear fusion reactions. Specifically, the scientists adapted collision detection algorithms, which are fundamental calculations done in video games to produce realistic models of how objects interact in space.Diagram of nuclear fusion process, from the IAEA.Predicting particle collision is vital for progressing fusion technology. The quest for profitable fusion energy has long been stymied by fusion's high energy and computational costs, and the high costs of current fusion reactors. As the scientists stated in their press release, fusion reactors require the injection of extremely high-energy particles; while collisions between particles are desired, the energy of the particles makes collisions with reactors walls highly likely, too. Particles that hit reactor walls may destabilize the reaction, reduce the effectiveness of the fusion process, or even harm the reactor. This algorithmic advancement could allow engineers and scientists to make reactors safer, more efficient, and more stable.Continue Reading at GameSpot...
