This cutting-edge propulsion concept harnesses quantum vacuum fluctuations to generate thrust. Although still in the experimental phase, recent discoveries suggest that propulsion without conventional propellants is achievable. By manipulating quantum fields, the technology creates differential pressure in the vacuum of space, enabling submarines to move through water with minimal acoustic signature and energy consumption. Research centers worldwide are working to transition this technology from laboratory demonstrations to practical underwater applications, with promising results in reduced cavitation and improved efficiency.
