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 ...

There are a remarkable number of commercial fusion power startups, considering that it’s a technology that’s built a reputation for being perpetually beyond the horizon. Many of them focus on ...

The Wendelstein 7-X stellarator in Germany has broken the record for plasma duration in a nuclear fusion reactor. Fusion reactions were sustained at high performance levels for 43 seconds, which is a ...

Commercial fusion power – electricity from facilities that will exploit the same thermonuclear fusion process that enables the sun to provide the planet with life-sustaining heat and light – may no ...

As noted in the paper by [P. Helander] et al., the use of permanent magnets can substantially simplify the magnetic-field coils of a stellarator, which are then primarily used for the toroidal ...

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 ...

A German startup has secured new funding for a peculiar twisted-looking reactor that could prove a quicker path to clean, virtually limitless fusion energy. Proxima Fusion has raised €20mn as it looks ...

Experiments at China's Experimental Advanced Superconducting Tokamak have confirmed the existence of "a density-free region" of the tokamak, finding a method to break through the density limit and ...

Nuclear energy as we know it today is generated through fission—the process of splitting atomic nuclei, which produces electricity without emitting greenhouse gases. The problem? Fission also creates ...
