In the next few decades, many physicists are hopeful that nuclear fusion could become a realistic source of practically limitless energy. But before this can happen, it will be critical to ensure that ...

The promise of nuclear fusion feels simple. Just as stars fuse hydrogen into heavier elements to produce energy, a fusion reactor generates massive amounts of energy by combining lightweight particles ...

Fusion reactors, devices that generate energy by fusing light atomic nuclei at extremely high temperatures, could contribute to ongoing efforts aimed at producing electricity more sustainably. The ...

Good news for fusion fans: A phenomenon that might have hindered efforts to generate energy using nuclear fusion may actually be beneficial. In computer simulations of two planned fusion reactors, ...

Terra Fusion is beginning work on a second-generation reactor in the Hollins Ferry area of Baltimore, he said. It will be able to produce 5 megawatts of electricity – enough to power about 4,000 homes ...

Nuclear fusion reactors offer the hope of vast, clean energy from the same process that powers stars. But despite decades of research, a reactor that can supply practical amounts of power has proven ...

Nuclear fusion may be closer to commercialization than previously thought, with private firms targeting operational reactors in the early 2030s. Major technical and economic hurdles remain, including ...

Nuclear fusion harnesses the immense energy released by the union of two lightweight particles. This requires extremely high temperatures and pressures—literally, this is how stars power ...

No one has made a fusion reactor capable of generating power, but physicists have a pretty good road map for how to get there. One major milestone is heating fusion fuel up above 10 million degrees ...

Inside a concrete pit near Cadarache, engineers have positioned ITER’s fifth vacuum vessel module—an ultra-precise step that brings the world’s largest tokamak closer to reality and moves the project ...

A Florida startup called AMPERA says it has completed production of what the company describes as the world’s first full-scale, 3D-printed nuclear reactor module. The hardware, which includes a ...

Back in the last century, smart alecks said that commercial fusion would always be 50 years in the future. Now, energy consultant Wood Mackenzie has taken to discussing developments in nuclear fusion ...
