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 ...

The stakes of the “race to fusion” are dramatic. Commercial fusion has the potential to deliver nearly unlimited energy by replicating the physics that powers the sun.

China breaks a historic barrier in nuclear fusion, bringing the dream of nearly infinite energy closer to reality.

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 ...

China is racing forward in its effort to pave the way in fusion energy science, and state-sponsored media reported earlier this week that one of the country’s next-gen reactors is now under ...

A US-based nuclear fusion developer wants to deploy a reactor in Japan in the late 2030s or early 2040s, in line with the Asian country’s broader plans to adopt the potent, low-carbon energy source.

“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 ...

The current AI race has reached a bottleneck that can be relieved only by new sources of electrical generation. Alongside the current demand for power, governments around the world continue to ...

General Fusion announced on Tuesday that it had successfully created plasma, a superheated fourth state of matter required for fusion, inside a prototype reactor. The milestone marks the beginning of ...

Inside a vast, hangar-like building in Devens, a trio of employees are working to test and assemble the pieces of what is likely one of the most advanced machines being built on Earth. One part of a ...
