A future powered by fusion energy is closer than ever before. This week, scientists at MIT got a large high-temperature superconducting electromagnet to a strength of 20 tesla. That’s the most powerful magnetic field of its kind ever created on Earth.

“Fusion in a lot of ways is the ultimate clean energy source,” Mari Zuber, MIT’s vice president of research, said in a Wednesday press release on the experiment. “The amount of power that is available is really game-changing.”
