Goal

Generate thermonuclear energy (heat) via acoustic cavitation of liquid metal.

Problem

Provide a method to produce net energy gain using fusion reactions without conventional high-temperature plasma confinement.

Concept Summary

Acoustic horns induce pressure waves in a sealed chamber containing a liquid metal (e.g., lithium, beryllium). The pressure variations create cavitation bubbles that grow and collapse violently, causing adiabatic compression that raises temperatures and pressures enough for hydrogen isotopes (deuterium, tritium) to undergo fusion. The resulting heat is extracted through the acoustic horns to an external heat exchanger.

Principles

  • Acoustic cavitation
  • Adiabatic compression
  • Thermonuclear fusion of hydrogen isotopes
  • Magnetic pulse gravity cancellation

Materials

  • Lithium
  • Lithium alloy
  • Beryllium
  • Aluminum
  • Tin
  • Indium
  • Thallium
  • Deuterium
  • Tritium

Mechanisms of Action

  • Acoustic pressure waves generate cavitation bubbles in liquid metal
  • Bubble collapse produces extreme temperature and pressure
  • Hydrogen isotopes in the bubble and host liquid undergo fusion
  • Heat is transferred to the liquid metal and removed via acoustic horns

Energy Sources

Acoustic (ultrasonic) energy

Applications

  • Heat generation
  • Power generation
  • Isotope production (helium-4, tritium)

Claimed Performance

Device of ~20 g produced ~100 W of heat from 50 W of acoustic input (~=2x net gain).

Experimental Evidence

In a tiny device of 20 g he produces piezoelectrically in heavy water bursting bubbles that generate about 100 watts of energy with an input of 50 watts.

Limitations

  • No independent peer-reviewed verification
  • Scalability of liquid-metal handling
  • Potential low overall efficiency

Red Flags

  • Claims of overunity without rigorous experimental data
  • Historical controversy surrounding cold-fusion research
