The stakes of the “race to fusion” are dramatic. Commercial fusion has the potential to deliver nearly unlimited energy by ...

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

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 ...

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 ...

There’s only one fusion device on earth that has been able to meet a key scientific threshold, but Maritime Fusion CEO Justin Cohen is already preparing to put a fusion reactor on a boat. Stay with me ...

Inside a vast, hangar-like building in Devens, a trio of employees are working to test and assemble the pieces of what is likely one of the most advanced machines being built on Earth. One part of a ...

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 ...

The promise of nuclear fusion feels simple. Just as stars fuse hydrogen into heavier elements to produce energy, a fusion reactor generates massive amounts of energy by combining lightweight particles ...

Nuclear fusion promises a green and infinitely renewable supply of energy—if we can harness it. Fusion happens all the time inside the sun. But to recreate the process on Earth, we must control ...

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 ...
