If anybody wants to see a cool artificial light that mimics natural light well take a look at coelux: [this video] It is imperfect (costs too much) but it'll give a good idea of why I think heliostat/optic cable/natural light is something more people need in their lives.

In this video ( [this video] ) they talk about the usage for underground buildings. It could be for underground buildings what the lift is for high buildings (eg make it practical). This was on Product Hunt a while ago: [LINK]

They are using these underground to help simulate the true daylight experience. Basically a smart led version of a traditional roof sunlight: [this video]

This is not new. See this video from 2014: [this video] This light is sold by [LINK] . They might also hold the patents on this technology.
