Book Description
The most prevalent failure modes in wind turbine drivetrains are main bearing failures stemming from micropitting, white etching or axial cracks in gearbox bearings, and generator bearing failures. These failures are neither well understood nor accounted for in design standards; consequently, the mitigation strategies being developed and fielded may only partially address the physics of failure and can take years to assess. The U.S. Department of Energy continues to support research programs to investigate the influence of rolling element sliding on the formation of bearing axial cracks and main bearing micropitting.

Book Description
Wind Turbines addresses all those professionally involved in research, development, manufacture and operation of wind turbines. It provides a cross-disciplinary overview of modern wind turbine technology and an orientation in the associated technical, economic and environmental fields. It is based on the author's experience gained over decades designing wind energy converters with a major industrial manufacturer and, more recently, in technical consulting and in the planning of large wind park installations, with special attention to economics. The second edition accounts for the emerging concerns over increasing numbers of installed wind turbines. In particular, an important new chapter has been added which deals with offshore wind utilisation. All advanced chapters have been extensively revised and in some cases considerably extended

Book Description
This book provides a detailed roadmap of technical, economic, and institutional actions by the wind industry, the wind research community, and others to optimize wind's potential contribution to a cleaner, more reliable, low-carbon, domestic energy generation portfolio, utilizing U.S. manu-facturing and a U.S. workforce. The roadmap is intended to be the beginning of an evolving, collaborative, and necessarily dynamic process. It thus suggests an approach of continual updates at least every two years, informed by its analysis activities. Roadmap actions are identified in nine topical areas, introduced below.

Book Description
In the tradition of Kitchen Confidential and Waiter Rant, a rollicking, eye-opening, fantastically indiscreet memoir of a life spent (and misspent) in the hotel industry. “Highly amusing."—New York Times Jacob Tomsky never intended to go into the hotel business. As a new college graduate, armed only with a philosophy degree and a singular lack of career direction, he became a valet parker for a large luxury hotel in New Orleans. Yet, rising fast through the ranks, he ended up working in “hospitality” for more than a decade, doing everything from supervising the housekeeping department to manning the front desk at an upscale Manhattan hotel. He’s checked you in, checked you out, separated your white panties from the white bed sheets, parked your car, tasted your room-service meals, cleaned your toilet, denied you a late checkout, given you a wake-up call, eaten M&Ms out of your minibar, laughed at your jokes, and taken your money. In Heads in Beds he pulls back the curtain to expose the crazy and compelling reality of a multi-billion-dollar industry we think we know. Heads in Beds is a funny, authentic, and irreverent chronicle of the highs and lows of hotel life, told by a keenly observant insider who’s seen it all. Prepare to be amused, shocked, and amazed as he spills the unwritten code of the bellhops, the antics that go on in the valet parking garage, the housekeeping department’s dirty little secrets—not to mention the shameless activities of the guests, who are rarely on their best behavior. Prepare to be moved, too, by his candor about what it’s like to toil in a highly demanding service industry at the luxury level, where people expect to get what they pay for (and often a whole lot more). Employees are poorly paid and frequently abused by coworkers and guests alike, and maintaining a semblance of sanity is a daily challenge. Along his journey Tomsky also reveals the secrets of the industry, offering easy ways to get what you need from your hotel without any hassle. This book (and a timely proffered twenty-dollar bill) will help you score late checkouts and upgrades, get free stuff galore, and make that pay-per-view charge magically disappear. Thanks to him you’ll know how to get the very best service from any business that makes its money from putting heads in beds. Or, at the very least, you will keep the bellmen from taking your luggage into the camera-free back office and bashing it against the wall repeatedly.
