Aquatankers
Cost effective, environmentally sensitive water transport solutions

A reliable supply of fresh water in urban areas is becoming a growing problem around the world. Aquatankers using proven Hybrid Marine Power technology offer a compelling solution with outstanding benefits.

The concept involves a series of supertankers specially designed and constructed for the carriage of potable water. The water is transported onto land through small, offshore facilities known as Single Point Moorings (SPMs). Using our unique Solar Wing sail with solar cell array technology reduces fuel consumption and emissions by nearly 50% on the voyages compared to the conventional tanker of this size and hydrodynamic characteristics.

Some of the many benefits of Aquatankers over pipelines & aquaducts include:

• environmentally sensitive
• relatively fast development
• social benefits
• relatively low capital costs
• exceptional reliability

• excellent scalability characteristics
• proven technology
• readily financed on the world equity
  & debt markets
• excellent potential for local content
  in construction & operation.

Unmanned Ocean Vehicles
Autonomous, self-propelled, high endurance unmanned vessels

Existing unmanned marine vehicles use fuel or batteries, and have limited endurance. Persistent surveillance of vast ocean areas requires high endurance platforms with plenty of electrical power for electronic systems. They must be low cost so it is affordable to deploy them in sufficient numbers. They must be rugged and reliable to weather extreme ocean conditions.

UOV's adapt the base technology of the Solar Sailor and integrates it into an autonomous, unmanned marine vehicle. By harvesting wind, solar, and motion energy, an Unmanned Ocean Vehicle (UOVTM) does not need fuel. It is self-propelled, self-deployable, and provides an inexhaustible supply of electrical power for sensors and communications. Its endurance is unlimited.

UOV's achieve this performance by integrating these features:

• Rigid wing sails covered with solar panels convert wind energy to propulsive energy. The rigid sails fold on deck in severe weather to prevent damage.
• Solar panels on all horizontal surfaces to collect electrical energy for electronics, sensors and communications, and for propulsion via electric motor.

• Large battery storage capacity sufficient for a week's operation. Provides continuity of power at night and in low wind. Battery weight is necessary for vehicle ballast.
• High efficiency DC motor-generator. When the UOV is propelled by wind, the motor-generator is turned by a propeller to generate additional electrical energy. It operates as a drive motor for propulsion in low-wind conditions and for tactical maneuvering.

UOV's are a new approach to achieving wide-area, persistent ocean surveillance for military, oceanographic and commercial applications. The vehicles have the unique ability to multi-task by doing military, intelligence and oceanographic missions concurrently or on a time-share basis.
