This video shows how sunlight can be taken from the roof and then piped into a building using fiber optics. Cuts down on electricity usage and emits a light that is healthier and more pleasing to the eyes.
Pretty cool technology, but I wonder how the economics of it break down. They state that this setup costs less than $10,000 lights 1000 sq feet and will last 20 years, but I have no idea how that compares with other lighting options.
