Fusion energy is often discussed as a matter of plasma physics, funding, and machine design, but bringing commercial fusion to the grid also requires a global industrial base that can manufacture critical components at scale. 1/4

In case you've been wondering — yes, we've been quite busy 🧲. We're now up to eight installed toroidal field (TF) magnets of the 18 total our SPARC fusion machine needs to help confine its superhot plasma. 1/2

The cryogenic team at CFS, responsible for the system that pulls heat from the SPARC tokamak and cools its magnets, recently hit a major achievement: Getting SPARC's cryogenic system down to its operating temperature of 8 kelvin. 1/4 youtu.be/eZcoMqijqDA

CFS is gearing up for SPARC’s dry dress rehearsal (DDR), firing up our tokamak’s support systems. In parallel with tokamak assembly, we're validating critical support systems like power and cooling under real operating conditions. 1/2

At CFS, we’re very confident that our SPARC tokamak will generate net fusion energy, a crucial performance threshold also called Q>1. 1/3

Big, world-changing technologies don't happen in a flash. They're built on days, then months, and then years of steady progress toward a singular goal. When we turn on our #SPARC tokamak and generate net fusion energy, it may feel like an overnight success to those who haven't tracked us. 1/3

The future of fusion isn't built all at once. As #SPARC moves closer to operation, our team is commissioning the systems that make fusion possible — 1/4

What's different now about commercializing fusion energy compared to past efforts? Three things, CFS CEO and Co-founder Bob Mumgaard told Adele Peters of @fastcompany.com. 1/5
