US: Optical fiber solar lighting systems gaining momemtum

With five hybrid solar lighting systems already in place and another 20 scheduled to be installed in the next couple of months, the forecast is looking sunny for a technology developed at the Department of Energy's Oak Ridge National Laboratory.

Preliminary data from field units, which collect sunlight and pipe it into buildings using bundles of small optical fibers, show potentially significant energy savings in lighting and maintenance costs. An added benefit is that, for most uses, natural light is vastly superior to artificial light.
