Inertia is a fusion-energy company that is taking the most direct, scientifically-proven path to commercializing fusion, leveraging the only successful achievement of fusion ignition, using a process that was pioneered at Lawrence Livermore National Laboratory. The startup’s reactor relies on a form of fusion known as inertial confinement. In Inertia’s flavor of inertial confinement, lasers bombard a fuel target, compressing the fuel until atoms inside fuse and release energy. The technique is based on NIF’s designs, in which laser light is converted into X-rays inside the target. The X-rays are what ultimately heat and compress the fuel pellet.
