CHICAGO--(BUSINESS WIRE)--Dec. 12, 2001

Roland Winston, chief scientist for Duke Solar LLC and long-time professor and past chair in the University of Chicago's department of physics and scientist in The Enrico Fermi Institute, received the prestigious Farrington Daniels Award for outstanding intellectual leadership in renewable energy from the International Solar Energy Society (ISES). The award, which Winston received on November 29 at the ISES annual conference in Adelaide, Australia, is the society's highest honor.

"This tribute reflects the level of commitment and excellence Dr. Winston brings to his work and the dedication he has shown to advancing solar technology throughout his entire career," said John F. Myles, III, chief executive officer of Duke Solar. "We are gratified that his revolutionary work has been recognized and are lucky to have him as Duke Solar's chief scientist."

Winston's pioneering work in non-imaging solar optics has developed technology that has been proven to concentrate sunlight at more than 84,000 times the natural level of Earth-surface sunlight. This technology has resulted in products and supplies to cool buildings, generate electricity, provide heat for industrial processes, and irradiate the surface of materials or to pump lasers. Winston's primary work with Duke Solar includes developing this groundbreaking technology commercially.

"I am deeply honored to be recognized by the international solar energy community for my work," said Winston. "Solar thermal technology has the potential to transform the energy industry as we know it for both commercial and residential use. Of the variety of uses of non-imaging optics, I consider the solar energy application to hold the greatest potential for societal good. Thanks to the contributions of many - my long-term colleague at the University, Dr. Joseph J. O'Gallagher, the many generations of talented graduate students, and Duke Solar, the courageous and innovative company that is implementing these new technologies - we can benefit as a society if we accept and embrace these new technologies. I hope that my research and work can help advance this endeavor.

The basis for Duke Solar's technologies, non-imaging optics is a patented technology that, when incorporated into the design of concentrating solar collectors, improves the efficiency of converting solar energy to thermal energy. The collectors are utilized in many different configurations - fixed arrays or tracking systems, roof-, wall- or ground mounted as well as building-integrated.

In addition to the Farrington Daniels Award, Winston's work in solar energy has been recognized by the Charles Greeley Abbot award of the American Solar Energy Society (1987), the C. Raymond Kraus Medal of The Franklin Institute (1996) and the Solar Personality of the Year of India (1999).

The international award was established in 1974 to honor the memory of Farrington Daniels, a founder and long-time member of ISES, and a University of Wisconsin, Madison, professor of chemistry who was a pioneer in renewable energy. The first award was presented in 1975 to Hoyt Clark Hottel, professor at Massachusetts Institute of Technology (MIT). The award is conferred every two years. Most recently, the award was presented to Ken-ichi Kimura, professor at Waseda University (Japan), in 1999.
