Cambridge Heavy Industries Developing Compact Fusion Device
Cambridge Heavy Industries, based in Cambridge, Massachusetts, has been developing a compact fusion reactor that fits on a tabletop. The startup aims to simplify the process of achieving controlled nuclear fusion by using fewer lasers and enabling rapid experimentation through its modular design. This approach allows for up to 80 experiments per day, with data feeding into AI-driven simulations to optimize performance. The company recently secured $6.2 million in seed funding led by Azolla Ventures, alongside other investors such as Overlay and the Neta Foundation. Cambridge Heavy’s reactor uses a novel laser-based method that compresses fuel targets efficiently at relatively low power levels. The technology was developed from research conducted under MIT chemist Keith Nelson. The company plans to scale up its design in about a decade for use in commercial fusion power plants, while also exploring the production of tritium—a rare isotope essential for most current fusion projects—offering potential revenue before full-scale energy generation.
