Passes momentum conservation, but magnetic scoop drag exceeds ionization thrust at sub-relativistic speeds.
- Interstellar hydrogen density is only ~1 atom/cm³, necessitating a scoop field > 5,000 meters in diameter.
- Bremsstrahlung radiation losses in the compressed p-p fusion core exceed achievable fusion power yield.
- 2026 technological readiness is constrained by magnetohydrodynamic scoop drag and high-temperature superconductors.
