Water fills at installation and never leaves the system. The flip repositions water from lower to upper chamber. No pump, no grid connection required for operation. Fully sealed after fill — zero contamination entry, zero biological growth risk.
A center tube runs axially through both chambers and annular neck. Water falls in the outer annulus. Air rises in the center tube. Fully separated — no competition, no air restriction. Faster drain. Tube is also the structural flip axis and vortex organizer.
The annular jet exiting the neck hits a cone tip on the tube end. The hollow ring jet splits radially to two Pelton runners on a common shaft. Both torques add. Both runners use 25° angled buckets (+29% over standard) and 21 Fibonacci buckets (zero resonance with 8 grooves).
Moving the air path from the chamber side to the central axis transforms it from a single-function component into a four-function architectural element that simultaneously solves air management, structure, vortex stability, and power extraction.
Innovations 16 and 17 remain prior art on their original dates but are superseded in the final design by Innovation 18.
Chamber section: 100mm diameter — 11.8 litre air capacity.
Neck section: tapers to 16mm diameter with neck.
Air volume 100mm bore: π×50²×1500mm = 11,781 cm³.
Thermal bladder: 2L rubber diaphragm still needed for seasonal expansion.
No floats. No valves. No flaps. Zero air management components.
After a flip, standard round chambers require 5 seconds of settling before vortex flow organizes. That dead time represents wasted phase output. The teardrop chamber converts the 13-second flip rotation into vortex nucleation energy — so Phase B begins with a fully organized vortex jet, not turbulent settling flow.
The top Z=573mm of each chamber has a teardrop/egg cross-section instead of round. The proportions follow φ: length:width = φ:1 = 1.618:1. The tip radius = 0.382 × Width. The broad end faces the flip rotation direction.
This is a nautilus cross-section. Cutting a nautilus shell horizontally produces this exact profile — each chamber grows by φ per turn. Nature evolved this shape for smooth asymmetric flow transitions with no separation zones.
Step 1: Flip begins. Water experiences F = M×ω²×r_cg = 17.5N lateral force from rotation.
Step 2: Water hits broad curved teardrop wall. Wall deflects it tangentially. The tip is a low-pressure zone. Water flows broad-end → around → toward tip. That IS circular motion.
Step 3: Rifled grooves in transition zone (Z depth) guide the nucleated rotation into organized circular flow. Fibonacci pitch: tight at tip, opens as circle forms.
Step 4: At t=13s (flip completion): vortex organized at neck entry. Phase B needle opens → clean jet immediately.
Z = 1.5m / φ² = 1.5 / 2.618 = 573mm
Above Z: teardrop cross-section — flip energy acts here.
Below Z: circular cross-section — vortex develops normally.
The teardrop zone is exactly where the water surface lives at phase start. It is only the top fraction of the chamber — most of the chamber is already circular. Just the water-surface region where flip force is acting gets the teardrop treatment.
Each section reduces the annular gap by 1/φ. Water velocity increases by φ per section.
| Section | Length | v_exit |
|---|---|---|
| F₁ | 55mm | ~10 m/s |
| F₂ | 34mm | ~16 m/s |
| F₃ | 21mm | ~26 m/s |
| F₄ (exit) | 13mm | 57 m/s |
Total neck length: 123mm. Inner wall = center tube surface (fixed). Outer wall = Fibonacci-tapered annular wall. Same principle as original solid neck — now annular around the center tube.
8 helical grooves at 25° pitch angle run through all 4 sections. The rifling creates the tangential velocity component that allows the angled Pelton bucket to extract an additional 18% of kinetic energy.
Groove count: 8 (Fibonacci F₆). Bucket count: 21 (F₈). 21÷8 = 2.625 — non-integer. Zero resonant frequency between groove excitation and bucket passing. No vibration fatigue.
Bidirectional: Phase A creates CW vortex, Phase B creates CCW vortex. Both orientations produce equally organized jets. The dual sprag clutch handles direction at the generator.
In the original design, air returned through the center of the neck annulus (a low-pressure hollow core). This required careful management to prevent air bubbles contaminating the jet.
With the center tube: air travels in the tube bore — completely inside the tube wall — never touching the water annulus. The jet at exit is pure water. No air entrainment. No bubble contamination. Clean, dense, dry jet hitting the Pelton.
Standard Pelton (0°): F_tangential = 0 N at center. All force is radial — zero torque contribution from the bucket angle itself. All drive comes from jet deflection only.
Angled Pelton 25°: F_tang = 180N × sin(25°) = 76N directly driving the runner. This is the tangential KE component from the rifled neck now captured. +29% power from bucket angle alone.
| Metric | 0° Standard | 25° Angled |
|---|---|---|
| F_tangential | 0 N | 76 N |
| Torque/magnet | 0 N·m | 24 N·m |
| Power gain | baseline | +29% |
The annular hollow jet from the neck hits a cone tip at the tube end. The cone deflects the ring jet radially outward to both sides. Each half feeds its own Pelton runner. Both runners are on the same common shaft.
Result: τ_total = τ_left + τ_right. Same water mass, same neck, same jet — two torques instead of one. Both runners use 25° buckets and 21 Fibonacci buckets.
Phase A produces CW vortex. Phase B produces CCW vortex. Without correction, Phase B would reverse the generator.
Two runners on the same shaft — one CW sprag, one CCW sprag. CW phase: CW runner engages, CCW freewheels. CCW phase: CCW engages, CW freewheels. Both phases always drive the shaft forward. Roller element sprags — silent, 5M+ cycle rated, no pawl wear.
Local: Runner disc itself acts as local flywheel. Covers 2.5s transition shock at phase start. No extra mass — runner IS the local FW.
Master: 197kg at r=30cm. Covers residual inter-unit ripple. Was 643kg single FW — 69% mass reduction from 2-stage architecture. Ripple: 27.3% per unit → local smoothing → √8 cancellation → <1% at generator.
The entire HGG control system operates passively. No sensors. No timers. No controllers. Each mechanical event is triggered by the physics of the previous one — a cascade of cause and effect that runs indefinitely without intervention.
At 85% of nominal RPM (1,532 RPM), centrifugal force on 3 shoes drops to spring force — clutch engages, drives flip mechanism.
Why 85% corresponds to h<20%: as head drops, Torricelli flow slows, Pelton torque drops, axle decelerates. RPM drop IS the flip signal. The 0.3s engagement delay filters transient faults (<0.1s) without missing genuine end-of-phase decline (>5s). No sensor needed — physics reads itself.
800kg counterweight · 0.8m arm · 60° swing.
Revised from 45° — torque margin at null was 0.45× (insufficient). At 60°: margin 1.6× ✓.
L_cw at null: 1,792 kg·m²/s + flywheel 9,326 = 11,118 combined. Water resistance: 2,943 N·m. Available torque: 1,390 N·m over 8s. Margin: 1.6×.
Phase B: CW on driving side — adds 57% extra drive force at Phase B start. Phase B nets +52,597 J above flip cost. CW pays for itself 29×.
Fibonacci-pitched lead screw on axle (5→8→13→21→34mm pitch). Spring-return follower loads axle proportionally to RPM.
Primary function: Passive RPM governor + progressive load-proportional clutch. Fine pitch at entry: aggressive early catch of over-speed. Coarse pitch at end: natural soft-stop, no impact shock.
Side effect: 3W incidental extraction of over-speed energy otherwise lost as heat. Not the reason to include it — the governor function is.
