We speak to Rob Akers, director for computing programmes at UK Atomic Energy Institute, about its new artificial intelligence (AI) supercomputer.

The hydrogen bomb, unlike the atomic bomb used on Hiroshima, generates energy through fusion by fusing isotopes of hydrogen, deuterium and tritium. This fusion process requires extremely high ...

Hydrogen bombs cause a bigger explosion, which means the shock waves, blast, heat and radiation all have larger reach than an atomic bomb, according to Edward Morse, a professor of nuclear engineering ...

What if the key to solving the world’s energy crisis was hidden in a process so ambitious, so technically demanding, that even experts once dismissed it as science fiction? For decades, nuclear fusion ...

The promise of nuclear fusion feels simple. Just as stars fuse hydrogen into heavier elements to produce energy, a fusion reactor generates massive amounts of energy by combining lightweight particles ...

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. This ...

Claims of “net energy gain” in fusion experiments often exclude the massive energy consumed by the full system, leading to misleading headlines. Even under optimistic timelines, commercial fusion ...
