For decades, fusion has been delayed and thwarted by failure, miscalculation, fraud and politics. It has been maddeningly always just out of reach, which seems to make people obsess over it all the more. “Fusion is the energy of the future… and always will be,” goes one old joke.
But today, fusion is being pursued with a renewed zeal, mostly because we’ve never needed it like we do now, and there are 37 countries currently collaborating to build the biggest experiment ever, in order to prove that fusion is viable.
Will this finally succeed? Or will the project collapse under its own massive complexity? The film chronicles the work of the passionate scientists who are struggling to make it work.
