The history of the Searl IGV, narrated by John Searl. The Inverse Gravity Vehicle (IGV) is claimed to be an experimental space vehicle powered by a Searl Effect Generator, capable overunity energy generation for space propulsion purposes. It’s essentially described as a craft that integrates one or more SEGs as both a power source and a propulsion/lift system.

In this slideshow, Searl narrates the history of constructing and testing the Searl IGV in the 1960’s, and describes numerous confrontations with scientific skepticism as obstacles that his organization had to overcome. He also describes some of the scientific and technical aspects of the Searl IGV craft, including a “mirror effect” on the bottom of the craft during flight in which the reflection of ground features underneath the Searl IGV are reflected from the force-field surrounding it.

John Searl describes the Searl IGV as being designed to take advantage of the antigravity effects generated by the Searl Effect Generator during operation. The Inverse Gravity Vehicle is envisioned as a disc-shaped craft powered by Searl Effect Generators, capable of both self-sustained electrical power and propulsion through “inverse gravity” fields. It represents a fusion of perpetual power generation and antigravity flight, but remains controversial and unverified, existing more in conceptual claims than in validated engineering.

Design of the IGV

• Form Factor: Usually depicted as a disc- or saucer-shaped craft, with one or more SEGs embedded in its structure.
• Core Drive System: The SEG’s concentric rings and rollers allegedly create strong electromagnetic and electrostatic fields when operating.
• Hull Integration:
  • The IGV’s body acts as a capacitor, storing high electrostatic charge.
  • The craft is said to ionize the surrounding air, producing a visible glowing or corona effect during flight.
• Crew Compartment:
  • Placed in the center of the disc, shielded from the intense fields.
  • Early illustrations show seating and controls arranged much like an aircraft cockpit.

Principles of Operation

• Levitation / Gravity Reduction:
  • At high rotor speeds, the SEG allegedly generates a powerful electrogravitational field, reducing the craft’s interaction with Earth’s gravity.
  • Searl described this as “inverse gravity,” hence the name.
• Propulsion:
  • By tilting or directing the SEG’s field gradients, the IGV supposedly produces thrust in any direction.
  • The motion is said to be smooth and silent, unlike conventional propulsion.
• Energy Self-Sufficiency:
  • Since the SEG is claimed to be a self-running generator, the IGV would require no fuel.
  • It would generate both propulsion and on-board electrical power indefinitely.
• Atmospheric & Space Operations:
  • In air: Lift aided by ionization and electrostatic thrust.
  • In space: Claimed to operate as a reactionless drive, using its field effects rather than expelling mass.

Reported Effects

• Corona Discharge / Glow: Witnesses of claimed tests reported the craft glowing, sometimes with pink or bluish light.
• Silent Motion: Described as accelerating without noise, shockwaves, or exhaust.
• Extreme Speed & Maneuverability: Supposedly capable of rapid direction changes without inertia felt by occupants.
• Thermal Anomalies: Said to become extremely cold during operation (a recurring claim with Searl’s machines).
