>> There are other tokamaks, but the MIT scientists expect their large tokamak to be the first in history that is capable of a self-sustaining reaction, and the first that generates more energy than it uses. And they expect to pivot immediately from this historic engineering feat to commercial energy production, and to do all of this on a relatively modest budget, and on a timeline of just three to four years.<p>This has a lot of expectations, but will be super exciting if they pull it off! By 2024 would be incredible.
