Engineers at the Massachusetts Institute of Technology (MIT) have successfully created a sophisticated, yet affordable, method to turn ordinary glass into a high-tech solar concentrator. Electrical engineer Marc Baldo, his graduate students Michael Currie, Jon Mapel and Timothy Heidel, and postdoctoral associate Shalom Goffri developed the concentrator made from dye-coated glass and announced their findings in the July 11, 2008, issue of Science. The device collects and channels photons otherwise lost from a solar panel's surface, dramatically boosting solar cell performance. In this video, Baldo explains the technology and its potential impact on the future of energy.
