Open research repository for the HCTGS (Hydro-Cascade Turbine Gravity Systems) family of gravity-powered water-energy infrastructure architectures and related technologies.
HCTGS systems exploit natural elevation gradients to deliver purified water and generate continuous baseload electricity without operational pumping energy. The research portfolio spans three core variants: HCTGS v1.0 (600m coastal shaft desalination), HCTGS v2.0 (800m mountain variant with U-tube freshwater recovery), and HCTGS v3.0 (spine-and-rib cascade topology for multi-city distribution across 500 km mountain fronts with dual-harvest generation and progressive MXene nanofiltration).
Related technologies hosted in this community include: Project URDHR (Unified Resilient Distribution for Hydrological Recycling — closed-loop artificial water cycle integrating Sahm Al-Matar atmospheric generation, HAAP v9 precision rainfall, and HCTGS gravity distribution), the Seraphim advanced materials ecosystem, and supporting publications on water security, climate resilience, and open-source infrastructure design.
