The Wind Done Gone (2001) is the first novel written by Alice Randall.
 It is a bestselling historical novel that tells an alternative account of the story in the American novel "Gone with the Wind" (1936) by Margaret Mitchell.
 While the story of "Gone with the Wind" focuses on the life of a wealthy slave owner, Scarlett O'Hara, "The Wind Done Gone" tells the story of the life of one of her slaves, Cynara, during the same time period and events.
Tara is the name of a fictional plantation in the state of Georgia, in the historical novel "Gone with the Wind" (1936) by Margaret Mitchell.
 In the story, Tara is located 5 mi from Jonesboro (originally spelled Jonesborough), in Clayton County, on the east side of the Flint River about 20 mi south of Atlanta.
Gone with the Wind is a novel by American writer Margaret Mitchell, first published in 1936.
 The story is set in Clayton County and Atlanta, both in Georgia, during the American Civil War and Reconstruction Era.
 It depicts the struggles of young Scarlett O'Hara, the spoiled daughter of a well-to-do plantation owner, who must use every means at her disposal to claw her way out of poverty following Sherman's destructive "March to the Sea".
 This historical novel features a "Bildungsroman" or coming-of-age story, with the title taken from a poem written by Ernest Dowson.
Tehachapi Pass Wind Farm is one of the first large-scale wind farms installed in the U.S. Wind development in the Tehachapi Pass began in the early 1980s by James Dehlsen and Zond Corporation.
 The first set of wind turbines installed were of American-made Storm Master brand, however they proved troublesome and eventually had to be replaced.
 Dehlsen quickly turned to Danish-built machines later, thus comprising the majority of the turbines at the pass.The area hosts a multitude of wind farms, comprising one of California's largest wind resource areas.
 The pass is undergoing much repowering activity.
 The area has multiple generations of wind turbine technology installed, including both single and double-blade turbines, as well as the more modern three-blade horizontal axis design.
 The older generation turbines generate kilowatts, and the modern turbines installed generate up to 3 megawatts, depending on the specific turbine and manufacturer.
 The Tehachapi wind resource area is a net exporter of generation to other parts of the state of California.
 A state initiative to upgrade the transmission out of Tehachapi (Tehachapi Renewable Transmission Project) began in 2008 and was expected to be completed by 2012.
 This has opened the door to further regional wind power development and multiple projects are expected to be installed to utilize that capacity.
 A prime location for viewing the turbines is off of State Route 58 and from Tehachapi-Willow Springs Road.
Suntrust v. Houghton Mifflin Co., 252 F. 3d 1165 (11th Cir.
 2001), opinion at 268 F.3d 1257, was a case decided by the United States Court of Appeals for the Eleventh Circuit against the owner of Margaret Mitchell's "Gone with the Wind", vacating an injunction prohibiting the publisher of Alice Randall's "The Wind Done Gone" from distributing the book.
The Mampuri Wind Farms (also known as the Senok Wind Farms, after its developers) are a set of three wind farms located near the Lakvijaya Power Station, on the Kalpitiya peninsula, in Mampuri, Puttalam District, Sri Lanka.
 The wind farms, referred to as Mampuri-I, Mampuri-II, and Mampuri-III, was built successively, and consists of eighteen Suzlon wind turbines ranging from 1.25 MW to 2.10 MW .
 Mampuri-I was commissioned on none }} , and was the first wind farm in the country to reach the 10 MW installed capacity threshold.
 As the government only allows projects up to 10 MW , the three wind farms are registered under three different company names, namely Senok Wind Power , Senok Wind Energy , and Senok Wind Resource .
The Making of a Legend: Gone with the Wind is a 1988 documentary outlining the successes and challenges of the casting, filming, and legacy of the 1939 film "Gone with the Wind", from concept to finished product.
 The documentary focuses on David O. Selznick from the time of the book's publication to the Academy Awards ceremony of 1940.
 Included are interviews with many of the crew and office personnel involved in making the film.
 Producer David O. Selznick struggled to control his project, working with three directors along the way--George Cukor, Victor Fleming and Sam Wood.
 Each had their own vision and the strong-willed men often clashed.
John Wiley, Jr., is an expert on "Gone With the Wind" and the life of its author, Margaret Mitchell.
 Over the past 40 years, he has assembled a collection of more than 10,000 items of "Gone With the Wind" and Mitchell memorabilia – including every American edition of the novel and more than 800 foreign editions.
 His collection is featured in the "Complete Gone With the Wind Sourcebook."
Era Records was an independent American record label located in Hollywood, California.
 It was founded by Herb Newman and Lou Bedell in 1955 as a pop, country and western and jazz label.
 Era had a #1 hit in 1956 with Gogi Grant's "The Wayward Wind", written by Newman.
 In 1959 Bedell sold his interest in the label to Newman.
 Artists who experienced hits on Era include Ketty Lester ("Love Letters"), Larry Verne ("Mr. Custer"), Donnie Brooks ("Mission Bell"), Dorsey Burnette ("Tall Oak Tree"), Art & Dotty Todd ("Chanson D' Amour") and The Castells ("So This Is Love").
 Era distributed other labels including Monogram, Gregmark and Eden.
 From 1969 to 1971, Era was associated with Happy Tiger, which reissued and distributed some of Era's oldies.
 In 1972, Newman added the RTV label, which released the MU album.
 In the mid-1970s Newman sold the Era label and catalog to K-tel.
 In 1993, K-tel began reissuing some of the early Era material using the original Era label and logo.
Crosswind kite power is power derived from a class of airborne wind-energy conversion systems (AWECS, aka AWES) or crosswind kite power systems (CWKPS) characterized by a kite system that has energy-harvesting parts that fly transverse to the direction of the ambient wind, i.e., to crosswind mode; sometimes the entire wing set and tether set is flown in crosswind mode.
 These systems at many scales from toy to power-grid-feeding sizes may be used as high-altitude wind power (HAWP) devices or low-altitude wind power (LAWP) devices without having to use towers.
 Flexible wings or rigid wings may be used in the kite system.
 A tethered wing, flying in crosswind at many times wind speed, harvests wind power from an area that is many times exceeding the wing’s own area.
 Crosswind kite power systems have some advantages over conventional wind turbines: access to more powerful and stable wind resource, high capacity factor, capability for deployment on and offshore at comparable costs, and no need for a tower.
 Additionally, the wings of the CWKPS may vary in aerodynamic efficiency; the movement of crosswinding tethered wings is sometimes compared with the outer parts of conventional wind turbine blades.
 However, a conventional traverse-to-wind rotating blade set carried aloft in a kite-power system has the blade set cutting to crosswind and is a form of crosswind kite power.
 Miles L. Loyd furthered studies on crosswind kite power systems in his work "Crosswind Kite Power" in 1980.
 Some believe that crosswind kite power was introduced by P. Payne and C. McCutchen in their patent No. 3,987,987, filed in 1975, however, crosswind kite power was used far before such patent, e.g., in target kites for war-target practice where the crosswinding power permitted high speeds to give practice to gunners.
