Zephyr Fusion is building the first in-orbit fusion power source - a compact, megawatt-class reactor designed to run in the vacuum of space. Founded by two physicists who met in grad school operating a spherical tokamak, the San Diego-based startup uses a levitated dipole magnetic confinement approach with high-temperature superconductors. Their bet: space makes fusion easier, not harder. With launch costs down 10x and mass-produced HTS tapes providing 10x more field per kilogram, Zephyr Fusion aims to power the industrial revolution that humanity is about to have off-planet.
