Windworks 8 - KW Wind System Prototype Development Report
This report summarizes Phase I (design and analysis) and Phase II (fabrication and test) activities of a DOE contract to produce a wind system capable of generating 8 kW in 9 m/s (20 mph) winds. The Windworks 8 kW prototype design consists of a 10 m (33 ft), three-bladed, downwind, flapping rotor which is connected to a three-phase, direct drive alternator. Rotor controls are hydraulic and allow the blades to be pitched for starting and governing. A major failure of a blade yoke limited performance testing at the Rocky Flats Wind Energy Research Center, but some operational data were obtained by the manufacturer at the Windworks facility. The prototype was successful in demonstrating the feasibility of several innovative concepts and influential in the later development of the Windworker 10, a commercially available wind system.
How Do Wind Turbines Work?
In recent years, it's become more common to see vast, open areas of countryside and costal areas filled with wind turbines. From the outside, these devices may look fairly simple, but inside, there are many complex parts that help turn the wind's energy into electricity. Readers of this engaging guide will get a look at the inner workings of these powerful machines and learn how wind turbines are capable of producing clean, renewable energy. Accessible text is paired with eye-catching photographs that will keep readers engrossed in this compelling learning experience.

The Wind Ensemble and Its Repertoire
As part of the mission of The Donald Hunsberger Wind Library, the 1994 hardcover edition (University of Rochester Press) of The Wind Ensemble and Its Repertoire has now been published in a paperback edition. This compendium of research includes "must have" information on the history and execution of the wind ensemble repertoire.
How Plants Work
Today's plants are descended from simple algaes that first emerged more than 500 million years ago, and now there are around 400,000 species. The huge diversity of forms that that these plants take is staggering. From towering redwoods, to diminutive mosses; from plants that developed stinging hairs and poisons, to those that require fire to germinate tor ocean currents to dsitribute their seeds. But how have we arrived at this mind-blowing variety in the plant kingdom? How Plants Work seeks to answer this intriguing question, drawing from a wide range of examples--from the everyday leaf to the most bizarre flowers--this book is a fascinating enquiry into, and celebration of, the rich complexity of plant life.
