Research under way at ORNL could lead to entirely new, highly energy-efficient ways of lighting buildings using the power of sunlight. In addition to providing light, the technology would convert sunlight to electricity much more efficiently than conventional solar technologies. In commercial buildings, lighting consumes more electric energy than any other building end-use. It accounts for more than a third of all electricity consumed for commercial use in the United States. Way cool. I remember, back in high school, thinking about how to do something like this. These "large-diameter" optical fibers are just the ticket. Hybrid Lighting |
