Fiber optics, that miracle of modern communications, can also be used to deliver natural light to spaces deep in a building. Last week I focused on tubular skylights, which provide a great way to bring daylighting into home offices, hallways, bathrooms, and other spaces. An aluminum tube that's highly reflective on the interior transmits daylight down through an unheated attic to the space below--delivering the light through what appears to be a fairly standard light-diffusing ceiling fixture. It's a great technology--especially with the relative low cost--but it has some limitations. You need a relatively straight shot, and it's hard to extend the tubes through living space to reach first-floor spaces in multi-storey buildings. 
For those with deep pockets, "active daylighting" using fiber optics provides a way to bring daylight deep into a home or commercial building--beyond the reach of tubular skylights. I know of two companies that are offering this technology: the Swedish companyParans Solar Lighting, AB (through its U.S. distributor HUVCO Daylighting Solutions), and theHimawari Solar Lighting System from La Foret Engineering Company, Ltd. in Tokyo, Japan.
