Could you build this?
No Zephyr Fusion is developing in-orbit nuclear fusion power systems, which requires deep nuclear physics, advanced hardware engineering, and space launch/orbital logistics that cannot be written in software.
What it would actually take: Building this requires advanced plasma physics modeling, high-temperature superconducting magnet design, space-rated vacuum and thermal dissipation hardware, and radiation-shielded space components. The challenge lies in plasma confinement physics, power-to-weight ratios for orbital deployment, regulatory clearance from nuclear and space agencies (FAA, NRC), and multi-million-dollar hardware testing facilities. Requires aerospace engineers, nuclear physicists, and specialized hardware fabrication.
