Engineers at the UK’s STEP (Spherical Tokamak for Energy Production) program have successfully tested ...

Nuclear fusion has long promised virtually limitless low carbon power, but the machines that might deliver it are notoriously ...

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

The machines at their center, called tokamaks, have evolved from experimental curiosities into instruments capable of sustaining confined plasma – matter so hot it mimics the ...

All of these new developments don’t mean that the sun is ready to give up its fusion monopoly, as many significant ...

Add Yahoo as a preferred source to see more of our stories on Google. A view of the Wendelstein 7-X fusion reactor, as seen on September 18, 2015 at the Max Planck Institute for Plasma Physics in ...

China's Burning Plasma Experimental Superconducting Tokamak fusion facility (BEST) has entered a new construction phase as it speeds toward its 2027 target completion date. The state-run nuclear ...

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 ...

The central solenoid is the heart of a fusion reactor, and a "jacket" of meticulously crafted stainless steel—capable of withstanding extreme temperatures and magnetic fields—protects it. Chinese ...

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 ...
