Commonwealth Fusion Systems said Tuesday at CES 2026 that it has installed the first superconducting magnet for its Sparc fusion reactor, a key milestone for the experimental system the company aims ...

A viable nuclear fusion reactor — one that spits out more energy than it consumes — could be here as soon as 2025. That's the takeaway of seven new studies, published Sept. 29 in the Journal of Plasma ...

Fusion power has long been treated as a mirage on the energy horizon, but the construction cranes outside Boston suggest ...

Commonwealth Fusion Systems has crossed two thresholds that fusion watchers have been waiting on for years: a giant superconducting magnet now sits inside its experimental reactor, and a fresh ...

“AI factories and data centers require gigawatts of electric power,” said Siemens CEO Roland Busch today at CES 2026. “What if we had an energy source that was clean, safe, affordable, and practically ...

Scientists in the US have introduced a novel artificial intelligence (AI) approach that can protect fusion reactors from the extreme heat generated by plasma. The new method, which is called HEAT-ML, ...
