Phase Energy Extractor: Conceptual Device

We describe a conceptual device based on the Binary Flow theory for extracting energy from the 90° phase mode of the vacuum. The device uses a resonant phase cavity tuned to the fundamental frequency ω₀ = 2mₑc²/ℏ to couple the vacuum's phase tension to a work extraction system. Design equations and operating conditions are provided. This document serves to establish intellectual priority and stimulate experimental development.
