Goal

Achieve levitation / anti-gravity lift using electromagnetic and ultrasonic mechanisms.

Problem

Providing a method to counteract gravity for hovercraft or lift-craft applications.

Concept Summary

The device combines high-voltage Tesla-coil circuitry, ultrasonic piezoelectric sound generation, rotating textured metal discs, and magnetic elements. By tuning voltage, frequency and ultrasonic vibration to resonance, the system is claimed to produce a levitating force that can lift the device for several seconds.

Principles

  • Electrostatics
  • High-voltage discharge
  • Resonance between electric fields and ultrasonic vibrations
  • Acoustic levitation
  • Magnetic vortex formation
  • Tesla coil operation

Scientific Domains

Physics Electrical Engineering Acoustics Materials Science

Materials

  • copper (brushes)
  • stainless steel (textured metal)
  • aluminum (foil layer)
  • polycarbonate (disc substrate)
  • electrolytic capacitors
  • piezoelectric ceramic
  • neodymium magnets (assumed)
  • pancake motors (metal housing)

Mechanisms of Action

  • Electrostatic attraction/repulsion between charged rotating discs
  • Acoustic pressure from ultrasonic piezoelectric speaker
  • Magnetic field coupling between discs
  • Resonant amplification of voltage and acoustic frequency

Energy Sources

12 V starter battery (DC) High-voltage switching power supply (Tesla coil) Secondary high-voltage power supply

Applications

  • Hovercraft / lift-craft
  • Aerospace propulsion concepts
  • Scientific research on levitation

Claimed Performance

Device was shown levitating for several seconds in video demonstrations; lift-craft can hover and be guided.

Experimental Evidence

Video recordings show the device hanging in the air for several seconds after disconnecting the starter battery; engineers have recreated parts of the schematic and observed similar behavior.

Replication Status

No independent, peer-reviewed replication reported; only anecdotal attempts by hobbyists and a small engineering team.

Limitations

  • Exact composition of the "special metal" not disclosed
  • No quantitative voltage/current specifications
  • Reliance on high-voltage circuitry (safety hazard)
  • Lack of independent verification
  • Unclear scalability

Red Flags

  • Claims of anti-gravity without peer-reviewed evidence
  • Potential pseudoscientific language
  • Absence of reproducible data or independent testing
