American fusion-energy startup, one of two hot fusion startups (alongside Helion) together worth some $10bn. CFS has signed contracts to provide power to Google and a big Italian client from the early 2030s. Co-founded by Brandon Sorbom, its chief scientist.
CFS uses the tokamak approach, in which small atoms are squeezed together by powerful magnetic fields inside a doughnut-shaped container filled with superhot plasma. Since their invention in the 1960s, tokamaks have been improving faster than the famously exponential Moore's Law for microprocessors, according to Sorbom. CFS credits the development of "high-temperature" superconductors, which operate at a balmy -200°C rather than -270°C and so require far less power to cool. They also create stronger magnetic fields than alternative materials. Thanks to reliable orders from CFS, its superconductor suppliers have increased production by a factor of 40 since the startup was founded in 2018.
