Pacific Fusion says it has finally found a way to make its ambitious fusion reactor design affordable enough to build at ...

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

This sector module is next in line for insertion in the tokamak pit. The assembly suspended in vertical tooling is composed of vacuum vessel sector #6 at the center, which is surrounded by a thin ...

Zap Energy’s three-meter reactor uses a lead-lithium liquid wall, cutting hardware needs and bringing cleaner, modular power ...

Fusion power has long been promised as a clean, abundant energy source, but scientists have struggled to harness it effectively. A new approach, however, may finally bring fusion reactors closer to ...

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 the heart of Provence, Southern France, the world's largest fusion energy experiment, which could be a step towards unlimited energy, has quietly entered perhaps the most critical stage yet. The ...

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 ...

Workers wear protective equipment in a cavernous hall that contains industrial equipment. The tokamak hall at Commonwealth Fusion Systems’ fusion energy facility in Devens, Massachusetts, will house ...

The world’s newest flagship fusion machine has barely finished proving it can work, and already it is heading into a long pause. After a high profile debut campaign that cost hundreds of millions of ...
