For long-time followers of fusion energy, Tokamak Hall is the high-water mark after decades of ups and downs. From an observation deck on the side, the surgically-clean, hospital-white room feels both ...

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 ...

US private fusion company Commonwealth Fusion Systems has installed the disc-shaped stainless steel cryostat base, marking the start of the assembly of the SPARC tokamak. Meanwhile, Fusion for Energy ...

Humanity probably isn’t on the cusp of a nuclear fusion revolution just yet. But along the way, we are getting some peeks at mind-blowing fusion experiments, so what’s the big rush? We submit this new ...

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 ...

Commercial fusion power plants may be cheaper and easier to build thanks to a breakthrough by TAE Technologies that allows reactors to generate their own containment fields without the need for ...

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 ...
