Utilizing Ocean Current Energy
Blue Energy Canada is commercializing the Davis Hydro Turbine, able to generate high-density renewable and emission-free electricity from ocean currents and tides at prices competitive with the cheapest conventional sources of energy today. Preliminary findings indicate that ocean current energy is one of the largest untapped power sources on the planet, capable of supplying both small and large-scale electricity to virtually every ocean bordering nation. The Davis Hydro Turbine, according to the company, is a technological breakthrough that 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 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. BEC is pursuing the development of a 500kW pre-commercial demonstration project off the coast of British Columbia, Canada. |  |
