none of the nasa prototypes became commonly produced as commercial generators because the purpose of the program was to develop the technology and support the emerging industry. many of the technologies such as doubly fed variable speed generators, light weight tubular towers, and the engineering design tools used in the wind industry today were developed and pioneered by the nasa program. total cost of the program between 1974 and 1992 was $330 million. for reference, the global wind market had reached $47 billion annually by 2008. general electric, boeing engineering and construction, westinghouse and united technologies were the commercial partners on the program, some of whom are involved in the wind industry today. although it has widely been stated that no commercial designs were produced, nasa's industry partners did indeed produce commercial turbines during this program such as the boeing mod-2 (described earlier) and westinghouse 600 kw turbines at kahuku wind farm in hawaii. when oil prices declined by a factor of three from 1980 through the early 1990s during what came to be known as the "1980s oil glut", many turbine manufacturers, both large and small, left the business. the commercial sales of the nasa/boeing mod-5b, for example, came to an end in 1987 when boeing engineering and construction announced they were "planning to leave the market because low oil prices are keeping windmills for electricity generation uneconomical." a summary of the doe/nasa large wind turbine program was published in 1984.
