After many years of experiments, the U.K. Atomic Energy Authority (UKAEA) is decommissioning the world's longest-running fusion tokamak. The project housing this machine is known as the Joint European ...

Experiments show fusion plasma can stay stable at higher densities by controlling reactor walls, challenging long-standing limits.

The dream of the ancient alchemists may come true as Marathon Fusion announces that its tokamak fusion reactor technology can turn common mercury into gold as a byproduct of fusion operations in ...

A nuclear fusion reactor in Germany has reached world record numbers for runtime. The tokamak dominates fusion research in 2025, but stellarators are making a comeback. A stellarator is still a donut ...

Scientists may have discovered a way to improve fusion reactors. Interesting Engineering reported on experiments inside a tokamak, a doughnut-shaped machine that contains plasma. Instead of only ...

For billions of years, the sun reigned supreme as the only fusion reactor in our solar system, leveraging its immense gravitational pressure and intense heat to overcome an atomic nuclei’s natural ...

Although nuclear fusion is exceedingly easy to achieve, as evidenced by desktop fusors, the real challenges begin to pop up whenever you try to sustain a plasma for extended periods of time, never ...

The sun-mimicking technology known as nuclear fusion hopes to create “limitless” energy by smashing light nuclei together using immense heat, but containing such hot plasma is proving tricky. A ...
