This paper presents the Gorelli Extended Siphon (GES), a hydraulic system in which the descending leg of a classical siphon is replaced by a closed vertical pipe whose length is at least seven times the submerged inlet segment (geometric ratio Rg ≥ 7). The central hypothesis, termed the GE Effect, postulates that the confined transient acceleration of the fluid column generates a sub-atmospheric pressure in the closed source basin containing a measurable residual term ΔPGE (t) beyond the classical trapped-gas model, arising from the non-stationary inertial force of the accelerating column. The paper provides: a formal falsifiable statement of the GES Principle; a numerical simulation via 4th-order Runge-Kutta integration of the unsteady equation of motion; five quantitative simulation graphs; a complete instrumented experimental protocol with statistical falsification criteria; and documentation of the operational sequence verified on a physical prototype (2019–2021). All numerical values are theoretical predictions requiring experimental verification. The GES Principle does not violate energy conservation; it identifies a non-stationary inertial regime not covered by existing stationary hydraulic models.
