Harvesting Quantum Vacuum Fluctuations via Micro-Electromechanical Systems

 The Casimir effect has long implied extractable energy from the vacuum, yet practical mechanisms remain theoretical. This article details a proposed MEMS-based resonator array designed to create dynamic boundary conditions that rectify zero-point energy. Using a non-equilibrium QED approach, we calculate a maximum extractable power density of 50 nW/cm² at a resonant frequency of 1.2 THz. While dwarfing current energy conversion efficiencies, the system requires near-absolute zero temperatures to prevent thermal noise from overwhelming the quantum signal, limiting applications to deep-space probes.
