Wind power represents one of the most promising sources of renewable energy and improvements to wind turbine design and control can have a significant impact on energy sustainability. This proposal is about a new design for efficient VAWT. Typically, VAWT power output is generated from the difference between the forces on the forward and backward facing blades to the wind direction. That reduces their efficiency as compared to the Horizontal Axis Wind Turbine (HAWT). The current innovation, eliminates the forces on the backward facing blades using dynamic blades which improve their efficiency to be comparablewith the HAWT.
In addition, the turbine is fitted with aerodynamic brakes that safely stop the turbine at low and high wind speeds. This safety feature does not exist in any Vertical Axis Wind Turbine in the market. The innovation received the Accelerator to Commercialization award in 2014 from the state of Ohio and University of Cincinnati. Several small size prototypes were builtwhich validated the concept.
VAWTs are capable of catching wind from all directions which avoid the need for yaw mechanisms, rudders or downwind coning. The electric generators can be positioned near the ground and are easily accessible for maintenance. The new invention will revolutionize thewind turbines andwind farms technology by improving the VAWT efficiency and safety.
The Technical Report Archive and Image Library (TRAIL), an open access digital library of U.S. federal technical reports, is now celebrating 10 years of existence. TRAIL is truly a labor of love, built from scratch and nurtured by a growing and passionate community of member organizations and volunteers. Through this group’s collective efforts, TRAIL has progressed from a small pilot (200 digitized documents) to the current library of 50,000+ technical reports, and contains content of interest to all disciplines. TRAIL provides an integrated website and search interface for discovery of reports from a range of federal agencies - well-known ones, such as the National Bureau of Standards (NBS), and obscure ones such as the Office of Saline Waters. This initiative is funded by its member organizations, including the Government Publishing Office (GPO), and works under the administration of the Center for Research Libraries (CRL). It represents a strong collaboration between government document librarians, subject librarians in academia, and the many partner organizations that support the digitization workflows (e.g., University of Michigan Google Book Project scanning) and donate content for digitization. This poster will describe TRAIL’s genesis and development, its growth in membership and volunteers (including our new no-cost “personal” membership option), lessons learned while fostering the LOVE and awareness of open access discovery and digital preservation, and future plans to increase the reach of TRAIL’s activities.
