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

Scientists in the U.K. have achieved a major breakthrough — a key step in unlocking greener, nearly limitless energy. The Times reported that researchers at the U.K. Atomic Energy Authority ...

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 ...

Scientists may have discovered a way to improve fusion reactors. Interesting Engineering reported on experiments inside a tokamak, a doughnut-shaped machine that contains plasma. Instead of only ...

Fusion firm Tokamak Energy has released the first high-speed color images of plasma from inside a fusion energy machine, providing new visual insights into the behavior of the “captured star.” This is ...

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

An experiment at the Princeton Plasma Physics Laboratory produced a 1-million-ampere plasma current with a new reactor last month, setting a world record for that type of reactor and opening the door ...

A fusion reactor dismantled in the UK and reassembled in the Czech Republic celebrated its first plasma late last year. The $32 million device was handed over for a symbolic £1. A fusion reactor ...

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 ...

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 ...

Tokamak plasma systems hold great promise in realising practical nuclear fusion, yet their full potential is constrained by the risk of disruptions – sudden, often catastrophic, losses of plasma ...
