US fusion firm Commonwealth Fusion Systems (CFS) has announced partnerships with Nvidia and Siemens to develop a digital twin ...

CFS has partnered with NVIDIA and Siemens to build an AI-driven digital twin for its SPARC tokamak, accelerating fusion ...

Commonwealth Fusion Systems (CFS) is developing a tokamak device called SPARC. The company aims to demonstrate the critical fusion energy milestone of producing more output power than input power for ...

A 75-ton, 24-foot diameter stainless steel structure, known as the cryostat base, has been installed as the foundation for the SPARC tokamak. This component, manufactured in Italy and shipped to CFS’s ...

Left: geometry of the SPARC tokamak showing the pump volume and the “louver” actuator that restricts gas flow between the plasma and pumping chambers. Right: neutral gas pressure increases strongly ...

Commonwealth has made measurable progress toward its goal of building a practical fusion reactor that generates carbon-free electricity. Explore the 2023 list of 15 Climate Tech Companies to Watch.

Nuclear fusion reactors are highly powerful technologies that can generate energy by fusing (i.e., joining) two light atomic nuclei to form a heavier nucleus. These fusion reactions release large ...

News media, the Biden administration, and scientists are pumping it up for what the outcome means for fusion power (monumental) and skeptics are pumping the brakes (still decades away). Chris Kelsall, ...

Commonwealth Fusion is working on Tokomaks with higher power magnets. SPARC would be the size of existing mid-sized fusion devices but with a much stronger magnetic field. SPARC plans to verify the ...

An artist’s interpretation of the inside of a fusion vessel, where some of the inner surfaces are directly exposed to the plasma. Some regions lie in the “magnetic shadow” of other components and are ...
