The first is a vortex concentrator, which is a vertical wing placed in the natural wind in a way that a strong wing tip vortex occurs; a turbine is then placed behind the wing tip in the concentrated energy region of the vortex to convert the energy to more directly-useful forms. The second concept involves a vertical axis turbine with straight blades; the blades are composed of special circulation controlled airfoils which show promise of increasing the overall efficiency of the turbine. Results of approximately the first year's theoretical and experimental investigation are reported, along with conclusions and recommendations for future research efforts.

Many of the changes were the result of the rapid influx of population associated with industrial activities. It has long been recognized that communities subject to rapid growth have difficulty meeting the physical facility needs of their residents, such as housing, shopping and school facilities, and sewer and water services. In recent years, a growing recognition of the importance of the social effects of rapid community growth has also developed. These effects include the deterioration of the quality of life valued by local residents, problems in integrating newcomers to a small community, the breakdown of interpersonal networks, and an unprecedented need for human services, which is the focus of this publication.
