Blue Energy The Davis Hydro Turbine

The Davis Hydro Turbine can be compared in design and output to an ultra-efficient underwater windmill.

Four fixed hydrofoil blades of the Davis Turbine are connected to a rotor that drives an integrated gearbox and electrical generator assembly. The turbine is mounted in a durable concrete marine caisson which anchors the unit to the ocean floor, directs the water flow through the turbine and supports the coupler, gearbox, and generator above. The hydrofoil blades employ a hydrodynamic lift principle that causes the turbine foils to move proportionately faster than the speed of the surrounding water. Computer optimized cross-flow design ensure that the rotation of the turbine is unidirectional on both the ebb and the flow of the tide.

The design of the Blue Energy Power System requires no new construction methodology: It is structurally and mechanically straightforward. The transmission and electrical systems are similar to thousands of existing hydroelectric installations. A standardized high production design makes the system economical to build, install and maintain.

The Blue Energy Power System's Davis Turbine modular design is capable of meeting any site application from 5 kW to 500 kW for river applications and from 200 MW to 8000 MW ocean installations.

The Davis Hydro Turbine forming the Blue Energy Power System is designed for modularity, according to two distinct scenarios (see graphics below):

- the Davis Hydro Turbine 'Ocean Class' system, which will link 7-14 MW units across ocean and estuarine passages;
- the Davis Hydro Turbine 'Mid-Range' 250-kW unit, which can operate individually or be linked together for remote and river-based applications;

to form Tidal Fence (concept proposed for Dalupiri Strait, Philippines)

The US Army Corps of Engineers, Canadian National Research Council, and Acadia Center for Estuarine Research have all provided independent testimonials of the Davis Turbine technology.

The Blue Energy technology is a key solution to the environmental energy crisis, providing significant advantages over conventional energy systems.
