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.

Well to be honest, I personally think that data centers are a huge waste of this emerging technology, but yeah, I suppose it's probably a perfect use case for fusion...

My question, is who can miniaturize their technology sufficiently to put it in a spacecraft? When we get fusion reactors in space we'll be able to use electric propulsion to make vehicles with insane range. We could send humans to Jupiter in a matter of months and have plenty of propellant for a return trip in a perfectly reusable vehicle. We already have all the tech for this, all except a suitable power source.

    Not in the top five problems of a Jupiter trip.

    Power and propulsion aren't in the top 5 problems?

    Well enlighten me, what's more important that we haven't figured out?

    Keeping a human alive healthy and capable of re-entry.

    We've done that. The ISS has been occupied for the last 25 years uninterrupted. The space station can go months between resupplies. In other words, we've shown that a crew can survive in a spacecraft without aid from earth for months. With some mission specific planning, I don't see why we couldn't manage a 6 month mission.
