Canadian startup General Fusion has been working on its unique approach to producing clean energy through nuclear fusion for two decades, and it's now got something major to show for it. The company ...

For the first time, a research team has demonstrated, in a metal-wall environment, a plasma regime that simultaneously ...

Nuclear fusion, which operates on the same principle that powers the sun, is expected to become a sustainable energy source for the future. To achieve fusion power generation, it is essential to ...

In February, France's WEST nuclear fusion reactor made a big step toward getting clean, star-like energy for everyone. The machine held superheated plasma for 1,337 seconds, or just over 22 minutes.

A fusion reactor in southern France achieved a significant milestone toward clean, limitless energy. The fusion reactor, WEST, created a super-hot plasma and sustained it for a record-breaking 6 ...

A student’s small bedroom has become a hotspot for nuclear fusion experiments. With no fancy lab or deep-pocketed sponsors, the work is entirely driven by curiosity and grit. Hudhayfa Nazoordeen, a ...

Many tokamaks use what is called positive triangularity plasma to produce energy, but past experiments have found that the inverse of this triangularity could be more stable. A new compact tokamak ...

Fusion energy has long promised the world a clean, nearly limitless source of power. But despite the excitement, real-world reactors must meet intense demands—both in performance and safety. Inside ...

Here’s what you’ll learn when you read this story: The plasma density barrier is a mathematical limit to the density of plasma that can exist in a tokamak before destabilizing. A new study led by a ...

The interiors of fusion reactors can get seriously chaotic. But for obvious reasons—like extreme temperatures and pressures—researchers aren’t typically able to peek directly inside a reactor. Some ...

Nuclear fusion usually brings to mind sprawling facilities, blistering temperatures, and machines built on a scale that can swallow budgets whole. This device does something stranger.
