A great look at the development of fusion reactors.

Great breakdown of Commonwealth Fusion Systems fusion reactor project in Massachusetts by MIT engineers. The goal to make fusion power on a smaller scale to very likely power large by large really large data centers for AI. As the need for powering these things are massive. Microsoft and Google are betting on it producing enough energy to power these massive data centers. Also the goal to do it in the early 2030's. The guy is a nuclear engineer with extensive background it fission reactors and fusion development.

He does a great breakdown of the extensive problems and that fusion not completely without issues. Some materials are not as abundant as people would sell it such as tritium there is only a few decades of supply currently. He talks about the size being limited to just 400 megawatts vs gigawatts as some big projects seek to build. But that is likely CFS sweet spot keep it reasonable focus on the goal and not try to just turn everything into a testing area.

The secret sauce in the development of their what is called tokamak is a donut-shaped magnetic confinement device designed to achieve nuclear fusion by heating a gas into a plasma and using powerful magnetic fields to contain it. What makes CFS tokamak special it is much smaller then ITER by a huge amount like way smaller. The photo above is CFS tokamak and how they got away with doing it this way was using new magnets that are far stronger then the ones used in ITER the huge French fusion reactor. The advancement in magnets is using REBCO or "RARE-EARTH-BARIUM-COPPER-OXIDE" magnets that are much more compact and powerful then the ones used in ITER. Photo above is CFS tokamak the photo below is the ITER tokamak.

As you can see how much bigger in volume the ITER is compared to CFS setup and ITER is around 30 billion already with needing 5 billion more with . no end in sight. As you can see very different approaches yet similar in goals.

The future is both challenging but promising with the development of these technologies. Could also make electricity cheaper with more sources of power such as wind, solar, nuclear power and fission and fusion on the way. Article by Philip Biron an avid technology fan and editor of Rad Space.
