An artist’s impression of what the new demonstration plant might look like GENERAL FUSION A company backed by Amazon’s Jeff Bezos is set to build a large-scale nuclear fusion demonstration plant in Oxfordshire. Canada’s General Fusion is one of the leading private firms aiming to turn the promise of fusion into a […]

Dr Greg Brittles, Tokamak Energy TOKAMAK ENERGY Dr Greg Brittles’ eyes gleam with excitement when he explains the project he is working on. “It’s every engineer’s dream really, to have a project that’s technically challenging, which requires you to develop new technology and solutions to hard problems, but that are […]

SPARC could be the first fusion reactor to produce net energy—a decade before ITER and in a machine 10 times smaller. CFS/MIT; T. HENDERSON A startup chasing the dream of plentiful, safe, carbon-free electricity from fusion, the energy source of the Sun, has settled on a site, timetable, and key […]

A conception of a compact fusion power plant, developed by researchers at the Massachusetts Institute of Technology ALEXANDER CREELY U.S. fusion scientists, notorious for squabbling over which projects to fund with their field’s limited budget, have coalesced around an audacious goal. A 10-year plan presented last week to the federal […]

It’s mission is to create and confine a plasma that produces net fusion energy. Credit: CFS/MIT-PSFC — CAD Rendering by T. Henderson Seven studies describe […]

ORNL researchers used natural tungsten (yellow) and enriched tungsten (orange) to trace the erosion, transport and redeposition of tungsten. Tungsten is the leading option to armor the inside of a fusion device.
