Thirteen Open-Source Innovations for Offshore Freshwater Production, Emergency Food Security, Microplastic Prevention, and Zero-Emission Cargo Shipping
Abstract
This article presents the inventions developed by Göran Skoog under the umbrella Skoog Architecture. The framework S.K.O.O.G. (Skoog Kinetic Orbital Oscillating Generator) and its sub-initiative Skoog Open Marine Technology (SOMT) encompass thirteen innovations spanning autonomous offshore freshwater production, emergency protein synthesis, proactive microplastic prevention, wave-energy propulsion, turbine design, surface coating technology, and navigation methodology. All technologies are released as open source under CC BY 4.0.
1. Introduction
The global shipping industry accounts for approximately 3% of CO₂ emissions, while over 2 billion people lack access to safe drinking water and millions face acute protein deficiency. The Skoog Architecture addresses these challenges through a single design philosophy: harvesting the ocean’s orbital wave motion, thermal gradients, and solar heat to generate freshwater, food, and propulsion without fossil fuels, electricity, or toxic chemistry.
The framework encompasses three primary branches: the Humanitarian Branch, embodied in the Skoog Buoy (SCSL) for water and the Skoog Tablets (SCLS) for emergency food, the Environmental Branch with SOMPF for microplastic prevention, and the Propulsion Branch centered on the Skoog Harvester (AWEV).
Skoog Buoy SCSL — Capillary Sweating Liana
The world’s first zero-electricity industrial water-from-air generator ready for coastal deployment. It sweats freshwater from humid ambient air using three passive energy inputs: deep-sea cold (approx 4°C), solar heat, and latent heat recovery.
A 1,000-metre closed-loop HDPE pipe—the thermal liana—brings 4°C deep-sea water to the buoy via wave-driven circulation. Humid air rises through an 18–20 metre solar chimney and passes through a capillary condensation matrix cooled by the riser pipe.
Production capacity:
- Compact unit (100 m² matrix): ~2,400 litres/day
- Standard industrial (500 m²): ~12,000 litres/day
- Large-scale (5,000 m²): ~500,000 litres/day
Delivery to shore: Freshwater is collected in a 200 m³ storage tank positioned above water level. This tank, combined with a 3-metre hydrostatic water column and 0.43% volumetric thermal expansion as stored water is heated to approximately 30°C, creates a water-tower effect. This enables delivery to shore over up to 30 km without pumping. The SAFA module creates a Venturi low-pressure zone that pulls airflow through the matrix without fans.
Skoog Tablets SCLS — Coastal Life-Seed
Open-source, electricity-free biotechnological architecture for emergency protein production. Transforms seawater into nutrient-rich biomass within 72 hours through a closed co-culture of halophilic organisms: Vibrio natriegens, Dunaliella salina, and Tetragenococcus halophilus.
Three-tablet protocol:
- Tablet 1 (Circle): Raises salinity to >7% to eliminate pathogens
- Tablet 2 (Square): High-energy substrate for explosive biomass growth
- Tablet 3 (Triangle): Initiates fermentation and flocculation
Safety barriers: Visual anthocyanin pH indicator, quassin taste barrier, mandatory 75°C thermal treatment. Each 72-hour cycle produces ~40g dry biomass with ~22g pure protein.
Skoog Open Marine Proactive Flocculant (SOMPF)
Materials science system that programs plastic to self-aggregate at the moment of fragmentation, preventing microplastic dispersal at the source before it enters the marine food chain.
Mechanism: Surface-anchored amphiphilic block copolymers respond to seawater ionic strength. At fragmentation, new functional surface is exposed while fragments are at maximum concentration. Charge screening + polymer bridging overcome repulsion between fragments, creating immediate aggregation.
Key advantages:
- Proactive, not reactive: Doesn’t chase dispersed microplastics. Neutralizes impact at point of origin
- Bio-physical barrier: Aggregates into >50 µm particles too large for cellular uptake by marine organisms
- Biofilm synergy: Modified surface accelerates bacterial EPS production that stabilizes aggregates into marine snow
- Industrial application: Applied via spray tunnel in 3-10 seconds at 60-120°C during plastic molding
- Brackish water optimized: Functions in Baltic Sea conditions (0.1-0.15 M salinity)
Status: Open source, CC BY 4.0. Technical specification: Zenodo DOI
The S.K.O.O.G. Architecture
Skoog Kinetic Orbital Oscillating Generator — the overarching framework for all propulsion technologies within Skoog Architecture. Core insight: ocean waves generate orbital particle motion, which is continuous elliptical rotation of water molecules. Rather than treating this as resistance, the architecture harvests it as the sole propulsion source.
Design philosophy focuses on the net energy surplus of the wave-energy platform rather than traditional speed metrics.
Skoog Harvester – Autonomous Wave Energy Vessel (AWEV)
Zero-fuel cargo vessel with a wave-permeable hull featuring through-going internal channels that allow waves to pass freely. Turbines in these channels convert kinetic energy into electricity for propulsion and storage.
Cargo module sits 10 metres below waterline, protected from wave motion and acting as active ballast. A 25-turbine research configuration with 10 m diameter turbines has estimated net output of 1.9–3.0 MW. Target: Handysize cargo ~20,000 DWT at 9–10 knots.
SKOOG LFAS — Lift-Force-Optimized Archimedes Screw
First Archimedes screw to exploit hydrodynamic lift as a torque-amplification mechanism along the entire axis. Each blade is profiled as an airfoil, generating a lift moment perpendicular to flow. Continuous radial twist keeps the lift coefficient nearly constant across the full blade radius.
Produces positive torque during both forward and backward wave phases, rectifying oscillatory flow into unidirectional rotation.
SKOOG DALAS — Dynamically Adaptive Lift-Force Archimedes System
Mounts the LFAS turbine on low-friction linear rails coupled to a Linear Permanent Magnet Generator (LPG). When a wave slam occurs, the turbine accelerates linearly with the impulse instead of absorbing it as shock, simultaneously eliminating mechanical stress and generating electricity.
First system to extract electricity simultaneously from both rotational lift force and linear wave impulse.
The Skoog Tacking Principle
Eliminates the rudder entirely. Two Azimuth-DALAS propulsion units positioned at each bow of the symmetrical double-ended hull create a controlled torque couple. Differentially vectoring their thrust positions the vessel at a 30–40 degree attack angle to the wave field, causing it to crab sideways while turbine channels remain aligned with orbital wave flux.
SKOOG Azimuth-DALAS Propulsion
Steerable ducted propulsors based on the same lift-force geometry as the DALAS harvesters. Ducted configuration achieves higher thrust efficiency than open propellers at low speeds while significantly reducing the underwater acoustic footprint. Allows precise maneuvering and directional thrust without traditional steering surfaces.
SKOOG PHST — Passive Hydrostatic Stabilization
Replaces expensive electronic bearings with a completely mechanical solution based on fluid-coupled hydraulic chambers. PHST is the first completely mechanical solution that stabilizes the rotor and stator while allowing the shaft to move freely.
Hydrostatic pressure adjusts automatically to rotor loads, preserving the microscopic air gap between rotor and stator without active electronics or scheduled maintenance. No sensors, no control systems, no power required.
SKOOG RDG — Wall-Integrated Shaftless Drive
Relocates the generator’s electromagnetic components from a central shaft to the outer rim of the turbine rotor, integrated directly into the channel wall. Eliminates the central bearing assembly, reduces mechanical losses, and allows the turbine to occupy the full duct cross-section for maximum energy capture.
SKOOG IAKKS — Active Ceramic Composite Coating
First marine coating to integrate ceramic wear resistance, active electrical antifouling, and structural delamination resistance. Uses brake-pad-grade particles (TiO₂, Al₂O₃) in an epoxy matrix to resist cavitation and ice.
A conductive mesh encapsulated in the coating emits a low-voltage pulse (1–12 V) to disrupt microorganism adhesion without toxic discharge. The mesh also mechanically binds the coating to the substrate, preventing crack propagation. Projected durability: ~30 years.
