Risky Business? Entrepreneurship In The New Independent-Power Sector, Wesley D. Sine, Heather A. Haveman, Pamela S. Tolbert May 2011

Risky Business? Entrepreneurship In The New Independent-Power Sector, Wesley D. Sine, Heather A. Haveman, Pamela S. Tolbert

Pamela S Tolbert

Building on sociological research on institutions and organizations and psychological research on risk and decision making, we propose that the development of institutions that reduce the risks of entering new sectors has a stronger effect on the founding rates of firms using novel technologies than on firms using established technologies. In an analysis of the independent-power sector of the electricity industry from 1980 to 1992, we found that the development of regulative and cognitive institutions legitimated the entire sector and provided incentives for all sector entrants; thus, foundings of all kinds of firms multiplied rapidly but had a stronger impact …


Wind Power Technologies: A Need For Research And Development In Improving Vawt’S Airfoil Characteristics, Rigoberto Chinchilla, Samuel Guccione, Joseph Tillman Apr 2011

Wind Power Technologies: A Need For Research And Development In Improving Vawt’S Airfoil Characteristics, Rigoberto Chinchilla, Samuel Guccione, Joseph Tillman

Straight bladed fixed pitched vertical axis wind turbines (VAWTs) offer several potential advantages over the standard horizontal axis wind turbines which are now in common use worldwide. The purpose of this study was to determine the need for further research and develop on improved airfoil or blade characteristics for use on straight bladed fixed pitched VAWT. This need was demonstrated by the design and construction of an airfoil that was physically modeled and field tested. The test showed that asymmetric airfoils would enable SBVAWTs to self start.
