The system is implemented in The Skoog Harvester — a cargo vessel concept designed to operate:

• Without fuel
• Without combustion
• Without exhaust emissions

The structural objective is long-endurance marine transport independent of fossil fuels, future environmental taxation, and refueling logistics.

This is not an incremental efficiency improvement. It is a propulsion architecture built around wave interaction as the primary energy source.

Core Hydrodynamic Innovation

Continuous Axial Lift — A Helical Underwater Wing

At the center of the architecture is a lift-optimized Archimedes screw — the first of its kind.

Unlike conventional displacement screws or segmented propeller blades:

• The entire helical surface is lift-optimized
• The geometry functions as a continuous underwater wing along its full axis
• Lift is generated continuously along the helix
• Low RPM produces high torque
• Oscillatory marine motion is mechanically rectified into directional rotation
• The screw behaves as a wing wrapped helically around a shaft

It is the first design capable of harnessing the orbital motion of waves in a ducted configuration and converting it directly into axial lift — essentially ”rectifying” alternating orbital flow into unidirectional thrust.

This capability has never existed before, making The Skoog Harvester architecture unique: the orbital wave energy, the largest untapped marine energy source, is structurally compelled to become usable propulsion.

Duct-Constrained Orbital Conversion

Both in the main vessel channels and in DALAS, the lift-optimized screws operate inside ducted passages.

Key points:

The channels are shaped as funnels, wider at the entrance, tapering toward the turbine center. This maximizes captured water surface area and guides flow toward the screw.

• Orbital motion cannot escape sideways, forcing conversion into lift
• Flow acceleration is naturally induced toward the central turbine
• The duct acts like a rectifier: orbital energy enters as alternating motion and emerges as unidirectional axial thrust

Efficient torque transfer

Because the system converts oscillatory orbital motion into continuous unidirectional rotation, the harvested mechanical energy can be transferred efficiently to electrical generation and propulsion systems.

In The Skoog Harvester configuration, the ducted lift-optimized screw primarily serves as an energy conversion device rather than a conventional marine propeller. Generated electrical power can then be used to drive dedicated propulsion units.

The Skoog Tacking principle uses dual propulsion units to achieve thrust vectoring without rudders.

Both DALAS and The Skoog Harvester share the same lift-optimized screw foundation:

• The Skoog Harvester — orbital bidirectional energy interaction in ducted channels
• DALAS — unidirectional resistance-to-linear conversion in ducted channels

The Skoog IAKKS System

The architecture integrates The Skoog IAKKS System, a specialized ceramic coating inspired by brake pad technology.

Key features:

• Internal pulsed electrical mesh embedded in the coating
• Prevents biological fouling
• Acts as a structural reinforcement, reducing the risk of cracking
• This embedded mesh is a completely new innovation, never implemented in coatings before
• Projected durability of approximately 30 years under harsh conditions
• Extreme wear resistance
• Long operational lifespan
• Elimination of toxic coatings
• Extended intervals between dockings

This system ensures durable protection of submerged surfaces, contributes to low maintenance, and supports long-term operational efficiency.

The Skoog Open Marine Technology (SOMT) initiative encourages open-source collaboration, sharing technical insights, and inviting feedback from researchers, engineers, and industry partners.

From Concept to Physical Validation

The S.K.O.O.G. Harvester has reached its milestone as a defined engineering framework. Having established the theoretical modeling and system logic, the technology is now transitioning from architectural specification to physical proof-of-concept.

All architectural materials for the Skoog Harvester are shared under the Creative Commons Attribution 4.0 International License. We believe in radical transparency to accelerate the global transition to fossil-free shipping.

Validation Readiness:
The Skoog Harvester is engineered for empirical verification. Following preliminary technical dialogue, maritime research institutions, such as MARIN, have expressed interest in conducting wave basin testing once project financing and formal test planning are secured.

The engineering design is currently prepared to transition into these physical evaluation phases to validate its performance in maritime environments.

Modular Development & Versatile Applications

Each component within the S.K.O.O.G. Architecture is developed as a standalone innovation. The functionality and commercial viability of these technologies are independent of the total system integration, allowing for diverse applications across the maritime and energy sectors.

• IAKKS Coating: Beyond the AWEV, this active ceramic system is designed for any marine infrastructure requiring long-term, toxic-free biofouling protection.
• SKOOG LFAS & SKOOG DALAS: These units are highly adaptable for use in stationary wave-power plants, hydroelectric installations, and advanced propulsion systems for conventional vessels.

Conventional wave-energy systems attempt to extract force from wave-induced motion, whereas the S.K.O.O.G. LFAS converts the orbital kinematics of the wave field itself into continuous lift-driven torque aligned with the screw axis.

Mobile Energy Harvesting & Green Fuel Production: The AWEV efficiency allows it to operate as a mobile energy plant. During transit or while stationed in energy-dense sea corridors, any net energy surplus can be utilized for on-site production of green hydrogen or fuels.

This turns the Skoog Harvester into a dual-purpose maritime asset, a zero-emission carrier that simultaneously functions as a mobile fuel generator.
