Nuclear fusion reactors, if and when they become practical, will need a steady supply of fuel. The source of that fuel is the ...

U.K. start-up Pulsar Fusion has unveiled plans to build a fleet of reusable nuclear fusion-powered rockets, known as Sunbirds ...

Lithium-6 is a crucial material for nuclear fusion reactors, but isolating it is challenging – now researchers have found a way to do this without using toxic mercury ...

It's part of the same government laboratory that ensures the safety and reliability of the nation's nuclear stockpile. "Every time we do a fusion experiment on the NIF, we are actually the hottest ...

Lithium-6 is essential for producing nuclear fusion fuel, but isolating it from the much more common isotope, lithium-7, ...

Nuclear fusion is a technology with the ultimate goal of controlling naturally unstable plasma. It uses even fewer resources and less fuel than fission, which was already very concentrated ...

A world record for nuclear fusion has been smashed after an ‘artificial sun’ reactor was able to maintain a plasma for more than 22 minutes. The WEST reactor, in southern France, is at the ...

they all operate using nuclear fission — but one energy startup has plans to change this. Commonwealth Fusion Systems (CFS), a spinoff branch of the Massachusetts Institute of Technology ...
