Tech that exploits the properties of the quantum vacuum—not empty nothingness, but a seething sea of "zero-point energy" where virtual particle pairs constantly pop in and out of existence. These technologies aim to extract energy, create propulsion, or manipulate forces by interacting with this underlying energetic activity of supposedly empty space.
Example: The hypothetical "Casimir engine." By using incredibly precise nanoscale plates, you harness the quantum vacuum pressure. Virtual particles of certain wavelengths can't fit between the plates, creating a net pressure from the more energetic vacuum outside that pushes them together. A cyclic engine could theoretically convert this push into usable work, literally getting power from the restless activity of nothingness. Quantum Vacuum Technologies.
