Sunlight in a tube 

Their new system. called hybrid solar lighting, would reduce this energy usage with fixtures that supplement or completely replace electric light with sunlight, at times when its available. The system is called hybrid solar lighting.

In the system, a rooftop collector concentrates and sends sunlight through optical fibers, tubes made of special, high-purity material that transmit light by reflecting it down their inner walls.

The fibers would transmit sunlight to special fixtures inside the building, which also contain high-efficiency fluorescent lighting. When the transmitted sunlight completely illuminates each room, the electric lights stay off.
