    • Applications in power generation involve harnessing ambient gravitational fields amplified by electric polarization, as explored in LaViolette's work on the B-2 bomber's electrogravitic assist for reduced drag and enhanced stealth.
      • Potential for zero-point energy extraction through high-frequency pulsing of capacitors to tap vacuum fluctuations.
  • Military and aerospace uses encompass stealth technology and directed energy systems, with declassified patents suggesting electrogravitic shielding to reduce inertial mass for high-speed maneuvers.
    • NASA-inspired patents from the 2000s focus on asymmetric field generators for satellite station-keeping, minimizing propellant use over mission lifetimes.
      • Emerging applications in materials science include levitation of objects for non-contact processing, leveraging thrust for precision manufacturing in microgravity environments.
