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

For decades, nuclear fusion has been described as the holy grail of clean power, a way to generate vast amounts of energy by ...

NIIEFA has tested a high-temperature superconductor wire (HTSC) for the TRT tokamak, achieving record current and magnetic field parameters.

Add Yahoo as a preferred source to see more of our stories on Google. Nuclear fusion promises a green and infinitely renewable supply of energy—if we can harness it. Fusion happens all the time inside ...

China's EAST reactor achieved plasma densities 1.65x beyond theoretical limits, solving fusion's 70-year puzzle and bringing ...

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

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 ...

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

Getting a significant energy return from tokamak-based nuclear fusion reactors depends for a large part on plasma density, but increasing said density is tricky, as beyond a certain point the plasma ...

An artist’s interpretation of the interactions between the plasma and the wall inside a tokamak fusion system. Lithium is shown in green, fuel is shown in red and atoms forming the tokamak wall are ...

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 ...
