The speculative practice of extracting usable work from the quantum vacuum's ground state energy. Unlike ZPE engineering, harnessing focuses on methods to tap into this energy, often portrayed as drawing limitless power from the seething foam of virtual particles. Proposed mechanisms often involve dynamic Casimir effects (moving mirrors in a vacuum to generate photons) or manipulating Van der Waals forces. In popular science and fiction, it's the hand-wavy power source for everything, despite physicists pointing out the vacuum state is the lowest possible energy; you can't milk the bottom of the well.
Example: "The UFO conspiracy guys swear the Tic-Tac crafts use zero point energy harnessing, with a quantum vacuum flux capacitor pulling free joules from empty space. Scientists sigh and explain you'd need to create a lower-energy vacuum below ground state first, which is like digging a hole in the bottom of the universe."
