The corporation intends to optimally exploit the diverse applications of its various clean-energy technologies by actively seeking out and forming strategic partnerships (that the Company may co-invest in) with brand-name industrial companies that are the leaders in the markets, which our technologies target. Centripetal Dynamics has secured strategic R&D relationships with a major aerospace company and other leading suppliers of aircraft, wind turbine and engine sub-systems for development and manufacture of the Company's energy systems, advanced wind turbines, heat recovery engines and hybrid biomass systems.
The trend is toward more efficient, lower cost, low wind speed power generation, combined with high reliability. Centripetal is uniquely positioned to capitalize on this demand with its technology. The Centripetal wind turbine's competitive advantages over conventional turbines are its low cost, high reliability, lightweight, increased efficiency and it's (COE of 3cents/kW) on a Class-4 wind-site. The Centripetal Wind Turbine will also provide low operating costs as well as a 10-15% reduction in "Balance of Station" installation costs.
"In the United States, wind-generated electricity is generally competitive for a grid-connected application in locations with high-quality wind resources such as Class 6 wind sites (6.7 m/s @ 10 meters). Currently, the unsubsidized cost of wind energy at Class 6 sites ranges from 4 to 5 ¢/kWh. Although near-term development of these high-quality wind resources is expected, the limited availability of Class 6 sites, coupled with their distance from load centers and transmission facilities, will constrain U.S. and Global wind energy development to a fraction of its potential."
"Current cost of energy (COE) levels for wind energy have been achieved by focusing development on Class 6 wind resource sites (average wind speeds of 6.7 m/s @10 m height) and by taking advantage of the production tax credits. With favorable financial terms, Class 6 sites can market electricity at prices of 4 ¢/kWh or less before the subsidy. However, as more sites are developed, easily accessible prime Class 6 sites are becoming less available. In addition, many Class 6 sites are located in remote areas that do not have easy access to transmission lines. The full development of accessible Class 6 sites may cause wind energy growth to plateau in the near future unless improvements in technology can make lower wind speed sites more cost effective.
The Class 4 wind sites (5.8 m/s @10 m) cover vast areas of the Great Plains from central and northern Texas to the Canadian border. Class 4 sites are also found along many coastal areas and along the shores of the Great Lakes. While the average distance of Class 6 sites from major load centers is 500 miles, Class 4 sites are significantly closer, with an average distance of 100 miles from load centers. Utility access to these Class 4 sites is more attractive and less costly. Also, Class 4 sites represent almost 20 times the developable wind resource of Class 6 sites. Currently electricity at Class 4 sites can be generated at costs in the range of 5 to 6 ¢/kWh.
Also, there are numerous Class 4 regions in the offshore waters of the US Great Lakes, Atlantic, Pacific and Gulf coastlines, many in close proximity to large load centers. The cost impact of offshore development, though not completely quantified is expected to increase overall COE by approximately 25% to 50%. Such offshore sites represent resources that can serve important coastal power markets through improving cost effectiveness in the technology."

To position wind energy for long-term growth, Centripetal will focus its efforts on wind turbine technology that will be the most competitive in the Class 4 (5.8 m/s) wind sites. This strategic objective will result in a twenty-fold increase in U.S. as well as global land areas suitable for wind energy development. For example, Class 4 wind resource areas are, on average, closer to major load centers than Class 6 areas by almost a factor of five. Achieving cost effectiveness at lower wind speeds will require technology improvements, such as the Centripetal Dynamics rotor technology, that builds on lessons learned from ongoing wind energy public-private research and development partnerships.
"The winds that blow across the Great Plains of the U.S. are capable of generating more energy than our Nation currently uses. To tap that vast energy resource and help balance our Nation's energy scales between consumption and production, we need to find ways to develop that resource to its full potential. Wind energy researchers have worked with industry partners for two decades developing advanced wind turbines designed to produce low-cost electricity in high wind, Class 6, resource areas where the average annual wind speed is 6.7 meters per second (m/s) at a height of 10 m (15 miles per hour [mph] at a height of 33 ft.). Our current wind capacity of almost 4700 megawatts (MW) is produced by wind farms located in some of our Nation's best wind resource areas
However, as the global wind energy industry continues to grow, the outstanding high wind resource sites with easy access to transmission lines will dwindle, leaving only hard-to access high wind speed sites and the lower wind speed areas. The full development of accessible high wind sites may cause wind energy growth to plateau in the near future unless improvements in technology can make lower wind speed sites more cost effective. Many of America's low wind speed or Class 4 wind sites, where the average annual wind speed is 5.8 m/s at a height of 10 m (13 mph at a height of 33 ft), are located in America's heartland on farms, ranches, and in rural communities from central and northern Texas to the Canadian border. Class 4 sites are also found along many coastal areas, around the Great Lakes, and along shallow coastal areas of the eastern United States."
