For a long time, the Greenwald limit was accepted as a given and incorporated into fusion reactor engineering. The new work shows that precise control over how the plasma is created and interacts with ...

The fusion power frontrunner said that construction on its Sparc reactor was proceeding as planned. Meanwhile, it's building ...

A number of concepts exist for exploiting the solar wind as a means of propulsion: the MagSail, the e-sail, and the plasma magnet. All of these concepts work predominately as drag devices and thus are ...

Three researchers from the US Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) have been awarded the 2025 Kaul Foundation Prize for Excellence in Plasma Physics Research and ...

CFS hits a key fusion milestone at CES 2026, installing Sparc’s first 20T superconducting magnet and building an ...

Helicon plasma propulsion represents a promising and multifaceted approach in the domain of electric space propulsion. At its core, the technology utilises helicon waves to generate high-density ...

A detailed study confirms that record-setting magnets built by the Plasma Science and Fusion Center and Commonwealth Fusion Systems meet the requirements for an economical, compact power plant.

Commonwealth Fusion Systems installs first of 18 massive magnets in Sparc fusion reactor at CES 2026, aiming to activate it ...

How do we extract energy from space around a spacecraft? If there are differences in the speed of the solar wind or differences in flows of particles around a spacecraft or where a spacecraft is ...

The VX-200 low temperature superconducting magnet has been delivered to Ad Astra’s Houston facility by its manufacturer, Scientific Magnetics Ltd. of Oxford, England and has successfully passed a ...
