In this work, we propose a theoretical scheme for extracting energy from the pressure gradient of superdense Ether. The operating principle is analogous to the hydraulic ram, known to have been used by Arab engineers at the Alhambra palace (Granada, Spain, 13th–14th centuries). In our model, the role of "flowing water" is played by the Ether flow generated by the cosmic density gradient. The role of the "valve" is played by an excited topological knot (a proton in an overstressed state). The rupture of phase continuity generates a longitudinal wave (the Spitsa Effect), which transfers pressure to a working element. The knot returns to its ground state, and the cycle repeats. Ether is not consumed — energy is drawn from its internal pressure. The energy density of Ether (ρE c2 ∼ 1029 J/m³) makes it possible to create compact energy sources with specific power orders of magnitude higher than chemical and nuclear sources. We provide a mathematical description of the cycle, the power balance equation, the concept of an interface based on curved domain structures, and an efficiency estimate. This work is purely fundamental and does not contain engineering blueprints for a specific implementation.
