For the past 20 years, MIT’s Plasma Science and Fusion Center (PSFC) has been experimenting with nuclear fusion through the world’s smallest tokamak-type (doughnut-shaped) nuclear fusion device — the Alcator C-Mod.
The goal? To produce the world’s smallest fusion reactor — one that crushes a doughnut-shaped fusion reaction into a 3.3 meter radius — three of which could power a city the size of Boston. [1]
