Fiber optics have enabled everything from light-transmitting concrete (LiTraCon) to see-through wood, but lately have found even more innovative applications for interior daylighting. Passing through a thin wooden wall or concrete block is one thing; Here natural light winds its way through entire stories of a structure, pushing through walls and ceilings to the innermost windowless spaces of a building.
Companies such as Huvco and Himawari, produce this technology however it is relatively expensive.
