Ultra Energy-Saving Renewable Energy Harvesting Ship

— A Next-Generation Vessel in Harmony with Nature —

1. High-Altitude Helium Wind Sail System (Helium Gas + High Position Wind Sail)

To capture strong upper-level winds over the ocean, the vessel employs a wind sail lifted by helium gas.
A counterweight beneath the sail ensures stability, allowing the system to utilize continuous high-altitude wind as a propulsion source.

2. Wind-Receiving Sails

Multiple masts are installed on the ship, with electric motors controlling the raising and lowering of the sails.
The system continuously harnesses tailwinds and combines them with high-altitude winds to maximize propulsion efficiency.
The sails are made of polyester-based Dacron, a fabric that offers both elasticity and high tensile strength.
Metal vapor deposition can be applied when additional reinforcement is required.
In addition, by supplying air bubbles beneath the hull and using a low-friction coating, hydrodynamic resistance is minimized to the greatest extent possible.

3. Biofuel Diesel Power Generation System (Biofuel Diesel Engine + Generator)

The vessel uses BDF (Biodiesel Fuel) and HVO (Hydrotreated Vegetable Oil) as its main energy sources.
Both are carbon-neutral fuels, effectively offsetting CO₂ emissions.
Generated electricity powers the propulsion propellers, onboard systems, and battery storage.
Tests have confirmed that adding hydrogen to BDF can reduce fuel consumption by up to 50%.

4. Ship Bottom Air-Bubble Supply Device

Initially designed for full-bottom air supply, the system has been optimized to provide partial, balanced gas injection to specific hull areas, improving stability.
Through refined hull geometry and fin configuration, stable navigation is maintained.
A high-performance seawater mixing device enables nanobubble oxygenation, supplying oxygen to low-oxygen marine regions.

5. Offshore Plant & Storage System (Various Factories & Storage Tanks)

The ship can host multiple onboard decarbonization and circular resource plants, including:

• UCDI Microbe (Prof. Yukawa, CO₂ Resource Conversion Institute)
  Converts CO₂ and H₂ into proteins, plastics, and isobutanol.
  This next-generation bio-material can multiply from 1g to 16 tons within 24 hours.
• Equatic Technology
  Electrolyzes seawater to convert CO₂ into calcium carbonate (CaCO₃) while generating hydrogen as a byproduct.
  Incorporates NASA’s oxygen-generating electrode technology.
• Mechanochemical Hydrogen Production (Hiroshima University Research Team)
  Utilizes physical reactions through impact and friction (ball milling) to produce hydrogen.
  When combined with advanced mixing devices, continuous H₂ generation becomes feasible.

By integrating these technologies, the ship achieves a self-sustaining “offshore CO₂-to-resource and hydrogen-production system.”

6. Advanced Hull Coating

The hull is coated with eco-friendly materials that minimize drag and prevent biofouling.

• Fluorine-based hydrophobic coatings
• Lotus-leaf-inspired superhydrophobic structures (Developed by Dr. Masanobu Naito, NIMS)
• Hydrogel-based hydrophilic coatings (Reduce wave-making resistance by up to 20%)
  These coatings balance marine ecological protection with enhanced energy efficiency.

7. High-Efficiency Generation Propeller

This is the ship’s core technology.
The propeller design offers superior rectification and propulsion efficiency.
A dual counter-rotating structure and controlled void ratio further improve power generation performance.
Based on the proven tidal systems by Orbital Marine Power (O2, Scotland), the ship envisions eight 5MW-class units.
Future composite large-scale CFRP blades developed by Japanese companies (e.g., Nakashima Propeller, Mitsubishi Chemical) are anticipated.

8.９.11 CO₂ and Inert Gas Storage Tanks

These tanks store CO₂, H₂, and other gases used in the onboard plants.
For vessel balance under varying wind conditions, tanks are installed on both port and starboard sides.

10. AI Control Tower & High-Altitude Sail Management System

AI continuously analyzes navigation, weather, and power generation data in real time.
It integrates wind direction, wind speed, and ocean current information to automatically optimize sail angles and navigation routes.
Linked to the central command onshore, it enables comprehensive energy management.
With next-generation solid-state batteries, the ship aims for a fully autonomous energy circulation system.

Vision

“A Moving Power Plant that Transforms CO₂ into Resources”

Harnessing nature’s forces to create a sustainable cycle of energy, environment, and resources,
