Clean energy from nuclear fusion may soon be commercial. But leaders around the world have done little to prepare.

Once a government-led pursuit, nuclear fusion is now a private-capital race, much of it financed by the same people building AI.

Nuclear fusion, the process that powers the Sun, has the potential to generate clean and abundant energy. However, it requires two atomic nuclei to collide head-on at high energies, and current fusion ...

Explore how fusion energy research is extending reaction times, highlighting nuclear fusion progress toward reliable, large-scale clean energy while explaining challenges, technologies, and future ...

For most of the past 70 years, fusion energy has been shorthand for a promise that never quite arrived, a running joke about a technology that was always a few decades away. That timeline has shifted.

In late 2022, Lawrence Livermore National Laboratory achieved a historic nuclear fusion breakthrough by creating a fusion reaction that produced more energy than the lasers used to create it.

While not as highlight-reel worthy as the Winter Olympics and the World Cup, experts expect high-performance computing (HPC) to have an even bigger ...
