ZPF

Douglas Miller's design for the Zero-Point Field MEMs Array (he also calls it the ZPF Array), a micro-fabricated chip from his company Zero-Point Field Technologies LLC. Its GHz-actuated wedge cavities polarize virtual particle pairs to push off the quantum vacuum, an approach Miller frames as modulating the vacuum for navigation rather than extracting energy from it. He builds it on the Haisch-Rueda-Puthoff 1994 inertia model and Barry Setterfield's variable-constants hypothesis. The numbers are projections, not measurements: the near-term prototype targets just 3 to 15 millinewtons at 10W, while the company's scaling math projects 0.6 to 2.4 newtons of directional thrust per square centimeter (and 1 to 9 newtons of upward, anti-gravity force) for a full array. As of May 2026 the project sits at the design stage with a fabrication-ready package, a provisional patent (US 63/820,876) with a non-provisional filing planned for June 2026, and roughly $5,400 invested against a $350K prototype ask inside a wider $1M raise, with no grants or test results yet. Miller hopes to build the prototype with a university partner (he names Rice University's nanofab and Embry-Riddle) and to pursue an NSF STTR. The October 2025 Tim Ventura livestream that 4Orbs first drew on cited an earlier, vaguer figure of 6+ units of thrust from 10W.
