Nuclear fusion combines light hydrogen atoms to release energy, similar to the sun's processes. Fusion reactors are ...

A persistent asymmetry in fusion exhaust has challenged researchers for years. New simulations show that plasma core rotation, working together with cross-field drifts, determines where particles land ...

Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the ...

A 0.5-tonne superconducting magnet recently hovered silently inside a 5-meter-wide vacuum chamber, which marked ...

New Zealand-based fusion energy startup OpenStar Technologies says it has become the first commercial company in the world to successfully create and confine plasma using a levitated dipole reactor.

At the same time, a current of cold electrons travels toward the heated plasma from the opposite direction. When the two meet, the plasma develops filament-shaped instabilities that SLAC’s facilities ...

EAST’s accomplishment is notable since the density limit has long prevented researchers from increasing plasma density past a certain point. Higher plasma density has historically been associated with ...

This is where Godzilla earns its keep. Standing four meters tall and capable of lifting 2.3 metric tons, Godzilla is the ultimate testbed. Starting in March 2026, the robot will begin testing over 30 ...

The big picture: For decades, the promise of fusion power seemed just out of reach – a theoretical miracle of physics that stubbornly refused to move from blueprint to breaker box. Yet in laboratories ...

Researchers in France have set an impressive new record. For 22 breathtaking minutes, blazing-hot plasma swirled inside the WEST tokamak, setting a new world record for plasma duration. A tokamak is ...

For six decades, the Bull Run Fossil Plant in Claxton, Tennessee, powered a region on fossil fuel. Last year, the plant was decommissioned, collapsing the plant's ...

French molten salt reactor developer Stellaria has announced it is seeking the necessary authorisations to construct an experimental reactor. Its application is now under review. A rendering of Alvin ...
