The video game-boosted digital reactor performed so well it could lead to great improvements in reactor technology. A fusion reactor’s main job is smashing subatomic particles together in a searing hot, high-energy plasma cloud. Yet, keeping track of them, especially in the chaotic environment of a fusion reactor, is enormously difficult. The authors estimate that the video game-boosted algorithm could increase fusion reactor analysis by a factor of 15, while reducing 99.9 percent of those calculations. For the fusion dream to become a physical reality, we may first need to play with virtual fusion reactors—and that’s where video games reign supreme.
