Advanced Energy Systems Division
In 1976, the Company changed the name of the site to the Westinghouse Advanced Energy Systems Division (AESD), making it an R&D site for development of nonconventional renewable energy systems. According to the official announcement, AESD's mission would be "Engineering today's science into tomorrow's power systems." Under the leadership of Max Johnson, General Manager, AESD engineers designed and built prototype devices such as a heliostat, which was designed to concentrate sunlight (by means of a tracking, flat-mirror assembly) onto a fluid-filled tank mounted on a tower. This hot fluid could then be transferred to the ground and used to produce steam, spinning a turbine to generate electricity.
Among AESD's successes was the winning site and conceptual design proposal for the Solar Total Energy Project (STEP) in Shenandoah, Coweta County, Georgia, 35 miles (56 km) south of Atlanta along I-85. Financed as a joint project by Georgia Power Company (part of Southern Company) and the U.S. Department of Energy, STEP operated from 1982 until 1989. Covering more than 5 acres (20,000 m2), it was the world's largest solar thermal cogeneration project. It consisted of 114 tracking parabolic-dish collectors (7 m dia), which heated a transfer fluid that produced high-pressure steam for generating electricity that was fed to an adjacent knitwear factory owned and operated by Bleyle of Germany. Downstream of the turbine, medium-pressure steam was piped to the plant for knitwear pressing, and low-pressure steam was used to provide air conditioning. The project was dismantled in 1989 when the turbine failed and there were no funds to replace it or provide other needed maintenance on the facility.
Other work conducted at AESD included testing of nickel metal hydride battery prototypes. A phosphoric acid fuel cell was designed, built, and tested successfully. Dendritic web silicon photocells were built and tested, and that business was later sold and transferred to Solar Power Industries Inc. of West Newton, Pa. AESD engineers also built a prototype for a magnetohydrodynamic (MHD) system utilizing hot plasma gases emitted by a coal-fired power plant. The exhaust gasses passed through a copper plate channel, generating additional electricity .

Famous quotes containing the words advanced, energy, systems and/or division:
“For such an advanced civilization as ours to be without images that are adequate to it is as serious a defect as being without memory.”
—Werner Herzog (b. 1942)
“Parents find many different ways to work their way through the assertiveness of their two-year-olds, but seeing that assertiveness as positive energy being directed toward growth as a competent individual may open up some new possibilities.”
—Fred Rogers (20th century)
“We have done scant justice to the reasonableness of cannibalism. There are in fact so many and such excellent motives possible to it that mankind has never been able to fit all of them into one universal scheme, and has accordingly contrived various diverse and contradictory systems the better to display its virtues.”
—Ruth Benedict (1887–1948)
“The division between the useful arts and the fine arts must not be understood in too absolute a manner. In the humblest work of the craftsmen, if art is there, there is a concern for beauty, through a kind of indirect repercussion that the requirements of the creativity of the spirit exercise upon the production of an object to serve human needs.”
—Jacques Maritain (1882–1973)
