The breakthrough scientific moment for fusion power—and the potential for nearly limitless electricity from a so-called star in a jar—came at the end of 2022 when scientists at Lawrence Livermore ...

Senior Correspondent For long-time followers of fusion energy, Tokamak Hall is the high-water mark after decades of ups and downs. From an observation deck on the side, the surgically-clean, ...

Cold fusion, one of the most notorious blunders in science, is making a return – of sorts. Scientists have resurrected an experiment that was once claimed to show room-temperature nuclear fusion, ...

Google signed the first direct corporate power purchase agreement for nuclear fusion energy with Commonwealth Fusion Systems. The global race to achieve commercial nuclear fusion is intensifying, with ...

Nuclear fusion originates in our sun and other stars. Immense pressure and high temperatures in the core create a reaction, ultimately preventing it from collapsing under the force of gravity. "The ...

Net power through nuclear fusion, a long dreamed-of goal, may finally be within reach. Fusion technology is moving out of the lab and many companies, including recently-founded ones, are striving to ...

UK-based Pulsar Fusion announced it has successfully achieved first plasma in its Sunbird nuclear fusion rocket exhaust system. The demonstration, a world’s first for a rocket of this type, was ...

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 ...
