Commonwealth Fusion Systems (CFS) has verified the core plasma physics assumptions for its upcoming ARC fusion power plant following a peer-reviewed study published in the Journal of Plasma Physics.

The research confirms the ARC reactor design aligns with known physics, allowing the company to shift its focus toward detailed hardware engineering...

According to the validated models, the ARC plant will produce approximately 1.1 gigawatts (GW) of fusion power to generate 400 megawatts (MW) of net electricity for the grid...

CFS engineers are using this simulation framework to optimize upcoming design iterations, adjusting dimensions like tokamak width and divertor length to refine reactor performance before manufacturing begins.

I should clarify. I think increasing technological complexity can lead to progress, but I don't think it always does. I think progress from increasing technological complexity often follows an s-curve. I'm not denying the progress that has come from the significant technological advancement of the last few centuries, I'm just not sure continued technological advancement will lead to that same level of progress over the next few centuries.

Maybe, but many things are increasingly efficient. Maybe energy need for most things is plateauing and flat id goud enough. You’ll just need fusion for datacenters
