The industries which have provided these technological advances include the off-shore oil and gas, wind power generation, maritime, shipping and telecommunications. Submersible turbine-generator units according to the present invention utilize recent technological advances from several industries and incorporate them into an integrated power system. These technological advances include not only unique designs and equipment but also state of the art advanced materials, including composite materials. With worldwide awareness of the negative environmental impacts of fossil fuels on our global environment, growth in the use of renewable energy appears to be constrained only by the ability to produce and deliver it at an economic price. Moreover, the flow direction varies only 1.5 degrees from an otherwise steady northerly direction of flow. One of the greatest potential sources of ocean current energy in the world is the Florida Current as shown in Figure 2. The Florida Current is the portion of the Gulf Stream that runs in a northerly direction off the east coast of the United States from the Florida Keys to Cape Hatteras in North Carolina.

Importantly, it always flows in a northerly direction, twenty-four hours a day, so it provides a continuous, reliable source of energy. In one embodiment, the blades 500 form a helical configuration, a modification of a delta turbine, which ensures that a portion of the blades always angles perpendicular to the fluid flow.

Although the speed and exact location of the Florida Current can fluctuate from season to season and year to year, it is relatively stable, predictable and wide enough that the center portion is always within the current boundaries. Although power generated from ocean energy can be directly “plugged into” coastal load centers and remote communities, it is not restricted to these markets. Since ocean and tidal currents exist everywhere in the world and are either constantly flowing or extremely predictable, converting the energy in these currents to electricity could provide a predictable, reliable and, in some cases, base load supply of electricity to the electric power systems or remote sites in many parts of the world. As shown in Figure 3A, two potential tidal generation project sites may be located near the City of Anchorage. In addition to providing much needed electricity to the Anchorage area, where approximately one-half of the state’s population lives, tidal current generators can be located in tidal currents near to shore in remote, local “pockets” of demand.
Both projects could be easily interconnected with the local utility grid which serves the Anchorage area. The submersible power generation modules may generate electricity from both tidal currents and open ocean currents, and, additionally, may generate electricity via deployment in any other natural or manmade water flow, such as rivers, causeways, canals, and dams. In European Union countries, for example, a considerable premium over fossil fuel generation is currently being paid for “green” power. At 50 meters below the surface, for example, the water velocity distribution was found to be Gaussian. Flows are very consistent – in the range of 0.642 to 2.43 5 meters per second (1.25 to 4.73 knots) 99.7% of the time (within three standard deviations of the mean).
0.75 per kWH or more. This is enough electricity to power a substantial portion of the households near the southeast coast of the United States. Gripe dolor muscular . This bill also authorized funding of $632 million in fiscal year 2007, $734 million in fiscal year 2008 and $852 million in fiscal year 2009 for renewable energy research, development, demonstration and commercial application projects, including ocean energy projects. WO 2008/051455 PCT/US2007/022288 SUBMERSIBLE TURBINE-GENERATOR UNIT FOR OCEAN AND TIDAL CURRENTS RELATED APPLICATIONS The present application claims priority to U.S. The aerodynamic blades of the ADCF Turbine convert the energy in the ocean and tidal currents into mechanical energy that transfers through the turbine shafts to a permanent magnet generator. The generator converts the mechanical energy (i.e., RPM and torque) into electricity.

Additionally, the maximum velocities of the Florida Current occur during the peak months of electricity usage during the summer which means the maximum output of the submersible turbine-generator modules of the present invention would occur during periods when the power is most needed. Figure 30 depicts a cross section of one embodiment of a housing assembly of the present invention. Figure 29 depicts a see-through perspective view of one embodiment of a housing assembly of the present invention.

Figure 23 depicts a front elevation of another submersible turbine-generator module according to yet another embodiment of the present invention. Ejercicios para el dolor lumbar ciatico . Such submersible turbine-generator units according to the present invention preferably utilize a highly efficient turbine, known as the advanced design cross-flow turbine (“ADCF Turbine”), which is a derivation of the Darrieus turbine. According to the invention, there is provided a submersible turbine-generator unit for generating electricity from ocean or tidal currents, comprising: a.

Patent No. 5,451,137 for a “Unidirectional Helical Reaction Turbine Operable Under Reversible Fluid Flow For Power Systems”, the contents of each of which is incorporated herein by reference. The tremendous growth in renewable energy over the past several years is well documented and the rate of growth continues to increase each year.
Each turbine 420 thus comprises a plurality of airfoil-shaped blades 500 mounted transversely to the direction of fluid flow for rotation in a plane parallel to the fluid flow. At ultra low head fluid pressures, the turbines 420 are capable of achieving relatively high speeds. A submersible permanent magnet generator connected to the one or more turbines by a common rotating shaft (or shaft extensions) and preferably housed in a watertight enclosure. Ocean power generation, on the other hand, has essentially unlimited development potential, is predictable, if not constant. These, and other incentives, bode well for the continued development of ocean energy technologies, and the commercialization of ocean energy projects at an increasing pace. The greatest potential for development of tidal current projects in the United States is in Alaska, where tidal flows are greater than anywhere else in the United States.

For the above reasons, the upper Cook Inlet of Alaska can be a primary target for the development of tidal current projects. Since the Florida Current is relatively close to the shore and to the large population centers on the east coast of Florida, where significant and growing demands for electricity exist, it is ideal for development of ocean current power generation. In another exemplary embodiment, from one to several submersible turbine-generator units can be mounted on a single submersible platform to make a submersible power generation module.
A power electronics system controls, conditions and synchronizes the generated electricity.
In one exemplary embodiment, submersible turbine-generator units may be mounted on a variety of support structures in many differing orientations (underwater foundations, floating platforms, submersible structures, etc.). Operations may be monitored and controlled from on-shore computers, and the submersible modules may be brought to the surface for inspection and maintenance. Due to the severe terrain, weather and environmental constraints in Alaska, there is no integrated transmission system, which has resulted in the proliferation of nearly 120 public and municipal owned utilities. A power electronics system controls, conditions and synchronizes the generated electricity. Ocean and tidal currents are capable of providing a virtually inexhaustible supply of emission-free renewable energy.
