We present the Event Horizon Siphon (EHS), a theoretically grounded framework for harvesting energy from the extreme relativistic and quantum phenomena arising as matter approaches a black hole's event horizon. The system couples a stabilized Schwarzschild or Kerr black hole of approximately Earth mass with an infalling neutronium cluster from neutron star matter. Five extraction mechanisms are analyzed: accretion disk radiation, the Penrose process, quantum horizon siphoning, tidal inertia conversion, and gravitational wave harvesting. A novel containment material-the Inertial-Neutral Containment Material (INCM), realized as the Nullfold Cylinder-is introduced with negative gravitational mass and infinite inertial resistance. Estimated energy yield is ~10 44 J from a 1.4 M s neutron star-billions of times current annual global energy consumption.
