Bill Gates-backed Commonwealth Fusion Systems hits key reactor construction milestone | TechCrunch
Briefly

Commonwealth Fusion Systems (CFS) has successfully installed a major component, the cryostat base, of its Sparc demonstration reactor in Massachusetts, moving closer to its goal of net-positive fusion power. This 75-ton structure is pivotal to constructing the tokamak, a key feature of fusion reactors. Alex Creely noted this milestone signals a shift from industrial facility building to building the actual fusion machine itself. With significant backing from investors such as Bill Gates, CFS is positioned as a leading contender in the race for viable fusion energy, aiming to bring the Sparc reactor online by 2027.
CFS's installation of the cryostat base marks a significant transition towards building the actual tokamak, a crucial step towards demonstrating feasible fusion energy.
If successful, CFS's Sparc reactor could generate more power than it consumes, potentially leading the way in commercially viable fusion energy.
