Scientists at the Plasma Science and Fusion Center at the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts show the technology used to reach the record-breaking 20 tesla magnetic field, the strongest fusion magnet in the world, that is making new strides for carbon-free power. Recently the hot plasma fuel produced a net gain energy for the first time using magnetic fusion and the MIT team aims to have its first test plant providing sustained fusion energy by 2025.
