> In 2025, Polaris transitioned fully into operations. Our team is now conducting thermonuclear fusion operations daily, refining test parameters, and using real-time plasma, neutron, and electrical diagnostics to increase the amount of fusion energy we recover from the system. Polaris consistently exceeds both the plasma temperatures and FRC size achieved on Trenta.
> We also received final approval from the Washington State Department of Health to operate with deuterium\u2013tritium (D-T) fuel, marking the first time a private fusion energy company has been licensed to perform D-T fusion.
> One of our biggest milestones of the year was receiving approvals and beginning construction on the world\u2019s first commercial fusion power plant in Malaga, Washington.
What is not said: Achieving net energy from the Polaris test machine. Three years ago they announced that their commercial plant is planned to come online in 2028 and will provide energy for Microsoft.

And then Commonwealth Fusion Systems (backed by Google and Bill Gates) released this short video of their first "superstrong magnet" from high-temperature superconductors. The test machine needs 17 other magnets and will be finished this year (hopefully). They want to build a commercial 400 MW plant in Richmond, Virginia, in "early 2030s".
