BILL GATES-BACKED COMMONWEALTH FUSION SYSTEMS HITS KEY REACTOR CONSTRUCTION MILESTONE

Summary from the TLDR newsletter

Commonwealth Fusion Systems has installed a key component of its SPARC demonstration reactor called the cryostat base. The milestone signifies a transition into a new stage of the project that involves building the actual tokamak itself. SPARC is expected to come online in 2027 - if it works as anticipated, it could be the first tokamak to produce more power than it takes to run. Three other major pieces of the tokamak will be installed simultaneously later this year or early next year - it will take several months after that to ensure all of the pieces work together as planned.
