  • Scientists replicated their breakthrough December 2022 nuclear fusion experiment.
  • But this time, they produced even more energy from the experiment than the first time.
  • These experiments are history in the making, bringing us one step closer to a fusion-powered future.

In a second successful experiment, US scientists say they produced a nuclear fusion reaction that yields more energy than they put into it.
