Quantum Vacuum and Inertia: The Quest for Propellant-Free Propulsion
To the point
It surveys speculative ideas that the quantum vacuum is a real energy medium that could someday be tapped to propel spacecraft or alter inertia, drawing on the Casimir effect, warp-drive concepts, metamaterials, and researchers like Harold Puthoff, Alfonso Rueda, and Bernhard Haisch, with NASA and others exploring related experiments, though vacuum energy is uncertain and practical energy extraction remains unproven, making the whole notion provocative but speculative.
