Switchable Mirrors Win 2004 R&D 100 Award

July 07, 2004

A unique new type of energy-saving window material developed by scientists at the Environmental Energy Technologies Division of Berkeley Lab has been recognized with a 2004 R&D 100 Award. Given by R&D Magazine, the awards have been called "the Oscars of technology." The addition of this winner, and an R&D 100 award won by another Lab division (Materials Sciences for their work on nanomotors) brings the total of R&D 100 Awards won by Berkeley Lab researchers to 34.
