Fibre optics coupled with some innovative collecter design allows sunlight direct to carry the light of the sun indoors. The hybrid device allows sunlight (IR filtered) to be 'piped' to the destination required inside a building. This is a great thechnology and will augment PV based and grid based electric lights using opto-electronic sensors to balance the load. Fact of the matter is that bulk of the energy consumed for indoor lighting is used during daylight hours especially in office complexes. This device is a great example of clear thinking and use of modern materials. While factories and industrial sheds typically have some daylight harvesting mechanism's in place this should make it easier for line of sight constrained locations to enjoy the same benefits.
Looks like a great idea.
