A France-based company is using stellarator technology to accelerate fusion research in Europe. Renaissance Fusion is ...

If it’s able to hold the heat of a fusion-capable plasma, it could be a huge breakthrough. So what’s a stellarator? It’s a specific type of nuclear fusion containment geometry that ...

How a tokamak works: The electric field induced by a transformer drives a current (big red arrows) through the plasma column. This generates a poloidal magnetic field that bends the plasma current ...

Controlled hydrogen fusion−the key to cheap, abundant energy−is still miles away but it is getting closer. After a two-day conference at Princeton, N.J. last week, U.S. and British atomic ...

Physicists have been trying to design fusion reactors, technologies that can generate energy via nuclear fusion processes, ...

After all, achieving controlled nuclear fusion requires replicating the extreme ... the tokamak and the stellarator. These technologies employ magnets to confine plasma in a donut shape called ...
